Intraocular lens with degree factor and structure to improve peripheral vision

Abstract

Lenses and methods for improving peripheral and central vision of a patient are provided. The lens improves vision by having optics configured to provide optimal peripheral vision that minimize off-axis astigmatism at, for example, 20 degrees eccentricity, while maximizing in-axis visual acuity and contrast sensitivity. The method provides a design of an IOL that reduces optical errors in images generated in peripheral retinal locations of a patient's eye at a distance from the foveal center while maximizing coaxial visual acuity and contrast sensitivity.

Description

Technical Field

[0001] Embodiments of this disclosure relate to devices, systems, and methods of manufacturing intraocular lenses that provide corrective vision and also improve peripheral vision. Background Technology

[0002] Embodiments of this disclosure relate to vision treatment techniques, and particularly to ophthalmic lenses, such as intraocular lenses (IOLs), including, for example, crystalline IOLs and piggyback IOLs (i.e., IOLs implanted in an eye that already has an IOL).

[0003] Intraocular lenses (IOLs) are used to restore vision after cataract or other ophthalmic surgeries, in which the natural lens is replaced or supplemented by an IOL. When this surgery alters the eye's optical system, the typical goal is to improve central visual acuity. Recent studies have found that peripheral aberrations change when a monofocal IOL is implanted, and these aberrations differ significantly from those in a normally phakic eye. The primary change is peripheral astigmatism, the dominant peripheral aberration in the natural eye, followed by spherical aberration, and then higher-order aberrations. These changes can impact overall functional vision, including driving ability, fall risk, postural stability, and / or detection capabilities.

[0004] Several retinal diseases can also impair central vision, such as age-related macular degeneration (AMD) or central scotoma. Other conditions can affect central vision, even at a young age, such as Stargardt's disease, Best's disease, and retinitis pigmentosa. Visual outcomes in patients with these conditions can be improved by improving peripheral vision.

[0005] Glaucoma can also cause peripheral vision loss. Glaucoma affects more than 2% of the population over 40 years of age. Glaucoma patients gradually lose peripheral vision due to damage to the optic nerve. Central vision may decline very late in the disease. Because glaucoma can cause serious disabilities in daily life, including problems with walking, balance, fall risk, and driving, patients with glaucoma can benefit from intraocular lenses (IOLs), which can improve both central and peripheral vision.

[0006] Given the above, lenses that improve peripheral vision are needed. Summary of the Invention

[0007] This invention addresses the aforementioned problems by providing a lens with a power shape factor and diopter label power range corresponding to a lens having optimized coaxial visual acuity and contrast sensitivity and a blur parameter of less than 1.8 diopters (D), thereby improving peripheral vision. Furthermore, the provided lens has a shape factor and diopter label power falling within a subrange corresponding to the lens with optimal peripheral vision, minimizing off-axis astigmatism at 20 degrees of eccentricity while maximizing coaxial visual acuity and contrast sensitivity, wherein the optimized parameters are described herein.

[0008] Specifically, a first embodiment of the intraocular lens includes a lens body comprising: a refractive index between 1.40 and 1.50 including endpoints, a refractive power label between 17D and 23D including endpoints, and a power shape factor less than or equal to -1.0 and greater than or equal to -2.5. Advantageously, an intraocular lens providing a label power range and a power shape factor range according to the first embodiment allows for correction of peripheral astigmatism with a blur parameter less than 1.8D, while optimizing coaxial visual acuity. Within these ranges, the power shape factor is stable, meaning that structural features can be selected to produce lenses that predictably reduce off-axis astigmatism at a 20-degree eccentricity while optimizing coaxial visual acuity. These ranges are crucial for allowing predictable peripheral astigmatism correction for patients requiring a refractive power less than the transition point power. The transition point power is the label power corresponding to the shape factor of the plano-convex lens (which is -1).

[0009] The lens body may have a center thickness between 0.62 mm and 1.0 mm. The intraocular lens may also include an anterior tactile portion connected to the lens body, and the lens may have an arch height between 0.34 mm and 0.65 mm. The lens may have a thickness greater than -0.077 mm. -1 And less than 0.00mm -1 The first surface with a front surface curvature greater than -0.355mm -1 And less than -0.130mm -1 The second surface has a posterior surface curvature. Advantageously, selecting any of these parameters within their respective ranges increases the lens's adaptability by allowing implantation with industrially available inserters. These ranges for each parameter also prevent the lens from being too steep, and thus reduce discomfort during patient insertion. The corresponding selection of these parameters further allows the lens to have a power shape factor that is even more stable within the scope of this invention, further aiding the lens's ability to predictably improve peripheral vision.

[0010] The lens may include a refractive power label between 18D and 22D, including endpoints. The power shape factor may be less than or equal to -1.1 and greater than or equal to -2.0. Advantageously, these ranges of label power and power shape factor allow the lens to be optimized such that, for lenses with label power less than the inflection point power, the lens minimizes off-axis astigmatism while maximizing coaxial visual acuity. Within these ranges, the power shape factor of the lens is particularly stable, which is crucial for the ability to allow for larger predictions to achieve optimized lens structure features. The lens may include a center thickness between 0.70 mm and 0.90 mm. A front tactile portion may be attached to the lens body, and wherein the lens may include an arch height between 0.40 mm and 0.60 mm.

Advantageously, selecting any of these parameters within their respective ranges increases the lens's adaptability by allowing implantation with industrially available inserters. These ranges for each parameter also prevent the lens from being too steep, and thus reduce patient discomfort during insertion. The corresponding selection of these parameters further allows the lens to have a power shape factor that is even more stable within an optimized range, further aiding the lens's ability to predictably minimize peripheral vision while maximizing coaxial visual acuity.

Advantageously, an intraocular lens providing a label power range and a power shape factor range according to the second embodiment allows for correction of peripheral astigmatism with a blur parameter less than 1.8D, while optimizing coaxial visual acuity. Within these ranges, the power shape factor is stable, meaning that structural features can be selected to produce lenses that predictably reduce off-axis astigmatism at a 20-degree eccentricity while optimizing coaxial visual acuity. These ranges are crucial for allowing predictable peripheral astigmatism correction for patients requiring a refractive power less than the transition point power.

Advantageously, selecting any of these parameters within their respective ranges increases the lens's adaptability by allowing implantation with industrially available inserters. These ranges for each parameter also prevent the lens from becoming too steep, and thus reduce patient discomfort during insertion. The corresponding selection of these parameters further allows the lens to have a power shape factor that is even more stable within an optimized range, further aiding the lens's ability to predictably minimize peripheral vision while maximizing coaxial visual acuity.

[0018] The degree shape factor can be calculated using the radii of curvature defined along the axis of the first and second surfaces.

Advantageously, an intraocular lens providing a label power range and a power shape factor range according to the third embodiment allows for correction of peripheral astigmatism with a blur parameter less than 1.8D, while optimizing coaxial visual acuity.

The corresponding selection of these parameters further allows the lens to have a power shape factor that is even more stable within the scope of this invention, further aiding the lens's ability to predictably improve peripheral vision.

[0030] Intraocular lenses may have a refractive power label between 25D and 35D, including endpoints. The power shape factor is less than or equal to -0.40 and greater than or equal to -0.95.

[0034] The present invention also provides a set of intraocular lenses for improving peripheral vision; the set includes at least one lens according to a first and / or second embodiment; and at least one lens according to a third and / or fourth embodiment.

[0044] This disclosure considers a variety of ophthalmic lenses for vision correction and provides a reliable solution to the problems involved in implanting intraocular lenses into patients, and provides a reliable location for the structural features of IOLs with different label powers.

[0045] The embodiments of this disclosure incorporate the simple meanings of technical terms in the field of IOL. For example, as Figure 2 As shown, this disclosure relates to a haptics 320 attached to a lens body, configured to hold an IOL 300 in the proper position within a patient's eye. The haptics 320 establishes an anterior haptic plane 325, which serves as a useful reference point for comparing different lenses. The anterior haptics 325 is defined by a plane perpendicular to the optical axis and extending through the foremost surface of the uncompressed IOL haptics 320. Figure 2 As shown, the dome height 350 of the IOL is the distance between the front tactile plane 325 and a plane perpendicular to the optical axis, which includes the front surface 330 of the IOL body, as calculated according to the definition in ISO standard 11979-1. Figure 2 The measurement of the center thickness 310 is also shown, which is the difference between the sagittal thickness and the vault height as defined in ISO standard 11979-1. Figure 2The intraocular lens body has an anterior surface 330, a posterior surface 340, an anterior principal plane defined at least partially by the optical effects of the anterior surface of the IOL 300, and a posterior principal plane defined at least partially by the optical effects of the posterior surface of the IOL 300. This disclosure calculates the optimal possible structure for a given label power measured in refractive power. As used herein, “label power” refers to the refractive power as defined in ISO standard 11979-1, which can be calculated using ray tracing techniques. A center thickness 310, anterior surface curvature, and posterior surface curvature are used according to standards in the field of intraocular lenses. Standard materials used to form the IOL are within the scope of this disclosure. In various implementations, the optics may include materials such as acrylic acid, silicone, polymethyl methacrylate (PMMA), styrene-ethylene-butene-styrene block copolymer (C-FLEX) or other styrene-based copolymers, polyvinyl alcohol (PVA), polystyrene, polyurethane, hydrogels, etc.

[0046] This disclosure uses power shape factor values ​​of intraocular lenses (IOLs) to identify structural features of the IOL that are necessary to achieve different labeled powers, measured in diopters (D), which are appropriate for implantation in the patient. This involves managing and designing at least the structural features disclosed herein, as well as... Figure 2 With the structural features shown in Equations 1 to 10 below, the IOL of this disclosure performs very well in treating eye diseases and in maintaining the focus and clarity of foveal and peripheral vision for patients who receive implanted IOLs.

[0047] As an initial introduction, this disclosure uses at least two different IOL structures as non-limiting examples configured as peripheral vision correction IOLs to illustrate the features and benefits of the work disclosed herein. Figure 2 A lens is shown, wherein the concave surface faces the light source of the object to be imaged and / or the image. Both the front and rear sides of an IOL can have convex surfaces. A plano-convex IOL has a flat or substantially flat front surface and a convex rear surface.

[0048] The power shape factor varies for different types of lenses, but can be constant for lenses with a single plane. For example, for a plano-convex lens, a constant power shape factor is equal to -1 (-1). In non-limiting embodiments, an IOL with a power shape factor less than or equal to -1 (-1) is provided, and an IOL with a power shape factor greater than or equal to -1 (-1) is also provided. An IOL with a power shape factor greater than or equal to -1 can have a lens body formed differently from a lens body with an IOL having a power shape factor less than or equal to -1. Without limiting this disclosure to any particular power shape factor or label power, the lenses of this disclosure can have a label power range from about 17D to 35D to illustrate various embodiments. With a constant power shape factor (e.g., -1) for a plano-convex lens, the lens shape changes from the lens shape of a lens with a power shape factor less than or equal to -1 to the lens shape of a lens with a power shape factor greater than or equal to -1. Within the lower label degree range, including but not limited to the range from 7D to 17D, the anterior and posterior surfaces of an IOL do not necessarily exhibit the degree response expected from a simple surface with consistent curvature across both the anterior and posterior surfaces. Instead, the anterior and posterior surfaces of an IOL can effectively comprise complex surfaces with variations across the respective surfaces. Differences across surfaces may be in terms of surface curvature variations (i.e., exhibiting toroidal surface structures or Zernike surfaces) and may require further investigation to ensure the necessary reliable response is provided when the IOL is implanted in a patient.

[0049] The degree shape factor of the IOL is calculated according to the following formula: Among them, Power ant It is the power of the front surface of the lens body, and Power post It is the power of the rear surface of the lens body.

[0050] The front surface measure is calculated as follows: The back surface measure is calculated as follows: Among them, R ant R is the front radius of curvature, and R post It is the rear radius of curvature of the lens body. The first surface of the IOL defines the front radius of curvature R. ant And the second surface defines the radius of curvature R. post n IOL It is the refractive index of IOL, and n media This is the refractive index of the medium implanted in the IOL. For prescriptions using diopters, the radius must be given in millimeters.

[0051] The radius shape factor of the IOL is calculated according to the following formula: The radius shape factor utilizes the total labeled radius of curvature for each lens, while the diopter shape factor can be calculated using ray tracing techniques applied to intraocular lenses. In some non-limiting embodiments, the ray tracing technique may include utilizing a specific aperture size. The ray tracing technique may also combine the effects of a specific aperture size, optimal focus position, and spherical aberration on the diopter shape factor. For an ideal, simple surface with known curvature, the diopter shape factor and the radius shape factor may be equal, but their values ​​are not always the same, indicating more complex surface curvatures.

[0052] The lens manufacturer's formula explains how the focal length of an intraocular lens is affected by the radii of curvature of both the anterior and posterior surfaces, where F is the focal length and n... IOL R1 is the refractive index of the lens, R2 is the radius of curvature of the first surface, and R2 is the radius of curvature of the second surface.

[0053] Existing technological efforts, such as Figure 1 The IOL 100 shown focuses primarily on the lens manufacturer's equations to adjust the radius and focal length of the IOL, without delving into the variable power response that the anterior and posterior surfaces may exhibit during implantation.

[0054] The measurements given throughout this application are discussed in conjunction with the Liou and Brennan eye model (Liou HL, Brennan NA. Anatomically accurate, finite model eye for optical modeling. J OptSoc Am A Opt Image Sci Vis. 1997 Aug; 14(8):1684-95. doi:10.1364 / josaa.14.001684.PMID:9248060). For the lens of this disclosure, the dome height is selected in the range of 0.34 mm to 0.65 mm. The lens may include a dome height in the range of 0.40 mm to 0.60 mm or 0.50 mm to 0.55 mm. The dome height may be 0.65 mm. The center thickness is selected in the range of 0.62 mm to 1.0007 mm. The center thickness may be in the range of 0.70 mm to 0.90 mm or 0.80 mm to 0.85 mm. The shape factor can range from -4 to 0. These parameter ranges are chosen to provide lenses that can be implanted using industrially available inserters and to avoid producing overly steep lenses, thus reducing patient discomfort. For these reasons, lenses with a posterior radius below -4 mm are also excluded from this disclosure. In this disclosure, eye length is defined by the equivalent ZCB00 ( The paraxial focal point of the monofocal lens is fixed, and the power of the lens is 2D, which is lower than the label power of the IOL (i.e., an IOL with a label power of 22D uses an eye length corresponding to a 20D ZCB00 lens).

[0055] If, for an implanted IOL, the measured off-axis astigmatism, measured at a 20-degree eccentricity from the optical axis through the iris, is less than or equal to a threshold of 1.8D, then the implanted IOL can be classified as a lens for correcting peripheral vision. Eccentricity refers to the angular distance from the center of the visual field (such as the fovea). Off-axis astigmatism at 20 degrees can be calculated based on the peripheral blur parameters of the IOL measured at this angle. For example, for an IOL with a 20D label power for correcting peripheral vision, the peripheral astigmatism at a 20-degree eccentricity could be 1.3D or 1.7D.

[0056] Vectors J0 and J can be calculated. 45 In addition, there are sphere, cylinder, and blur parameters. These values ​​are calculated according to the following equations, where C(i,j) is the corresponding Zernike coefficient in μm, and r is the pupil radius in mm. For these formulas, the cylinder is defined using the convention of a negative sign, and the retinal curvature is defined according to Atchinson et al. (Optical models for human myopic eyes, 2006).

[0057] Reference Figure 4 and Figure 5 This disclosure provides a range of parameters crucial for lenses with labeled power, which correct peripheral vision based on blur parameters, achieving an absolute value of less than 1.8D for peripheral cylinders at a 20-degree eccentricity, and optimizing coaxial visual acuity and contrast sensitivity. Within the scope discussed herein, coaxial visual acuity and contrast sensitivity are optimized for selected values ​​of dome height, center thickness, and shape factor. For the selected values, coaxial visual acuity and contrast sensitivity are further optimized by adjusting the front and / or rear aspherical parameters to produce a lens with coaxial performance that is as close as possible to the diffraction-limited performance of a coaxial 5.65mm entrance pupil at green light (550nm). Figure 4 Curve 400 shows a peripheral vision lens with a refractive index of 1.471, which corrects peripheral vision according to blur parameters, has an absolute value of less than 1.8D for a peripheral cylinder at 20 degrees of eccentricity, and optimizes coaxial visual acuity and contrast sensitivity. Figure 5 The curve 500 shows a peripheral vision lens with a refractive index of 1.55, which corrects peripheral vision according to blur parameter conditions, has an absolute value of less than 1.8D for a peripheral cylinder at 20 degrees of eccentricity, and optimizes coaxial visual acuity. Figure 4 and Figure 5 Both charts show the shape factor and labeled power of lenses that meet the requirements. In both charts, the lenses are limited by a dome height between 0.34 mm and 0.65 mm and a center thickness ranging from 0.62 mm to 1.0007 mm.

[0058] Refer to each Figure 6 and Figure 7 The disclosure also provides subranges corresponding to optimal label power and power shape factor for curves 600 and 700, which are essential for peripheral vision lenses that minimize off-axis astigmatism at 20-degree eccentricity while maximizing coaxial visual acuity and contrast sensitivity. Figure 6 The optimal areas with a refractive index of 1.471 are shown as shaded areas 610 and 620. Figure 7 The optimal areas for a refractive index of 1.55 are shown as shaded areas 710 and 720. In both graphs, the lens is limited by a dome height between 0.34 mm and 0.65 mm and a center thickness ranging from 0.62 mm to 1.0007 mm.

[0059] To calculate these subranges corresponding to regions 610, 620, 710, and 720, the modulation transfer function (MTF) was optimized. It is well known that contrast sensitivity is proportional to the MTF; therefore, sufficient coaxial visual acuity and / or contrast sensitivity can be achieved by optimizing the MTF. Optimization can be performed at one or more spatial frequencies, or a figure of merit can be used that is proportional to the MTF level at one or more spatial frequencies. In a non-limiting example, sufficient contrast sensitivity is achieved if the MTF is at least 0.7 for a 5mm pupil in green light at a spatial frequency of 50 cycles / mm, as measured in eye model #2 according to ISO 11979-2 2014. The following parameters and their associated weights were used for MTF optimization: For a large entrance pupil of 5.65 mm (weight = 1), the lens was coaxially diffracted-limited; for an entrance pupil of 4 mm (weight = 0.01 each), each of off-axis astigmatism and off-axis defocus was reduced at 20 degrees; for an entrance pupil of 4 mm (weight = 0.02 each), the off-axis 20-degree MTF value of each of the sagittal and tangential focal points was increased at a spatial frequency of 25 cycles per mm; for an entrance pupil of as similar as possible of 4 mm (weight = 0.01), the off-axis 20-degree MTF values ​​of the sagittal and tangential focal points were increased at a spatial frequency of 25 cycles per mm. MTF was calculated using monochromatic green light at 550 nm. In the Liou and Brennan eye model, the anterior tactile plane of the lens was located approximately 0.5 mm behind the iris, and the retinal curvature was defined according to Atchinson et al. (Optical models for human myopic eyes, 2006). This optimization can be used to determine (according to the lens manufacturer's equation) how lens parameters, such as dome height, center thickness, anterior and posterior surface curvature, and shape factor, can be adjusted to achieve the most suitable subrange of label power optimized for improving the patient's peripheral vision. The subrange is then selected based on the observed region where optimization is most stable, so that the optimization effect can be predicted given appropriate selection of structural features.

[0060] Figure 3 An example of the characteristics of an IOL is illustrated by considering the corresponding refractive indices of the medium (n1) before the lens, the lens material (n2), and the medium (n3) after the lens. Using the known radii of curvature (R1, R2) of the front and rear lens surfaces, the surface power (i.e., Power) of the lens can be calculated according to Equations 2 and 3 given above. ant and Power post For Power ant n media Corresponding to n1, and for Power post nmedia Corresponding to n2. This disclosure includes surface curvature values ​​across multiple diopter labels for the front and rear surfaces of a plurality of different lenses having corresponding refractive indices. This disclosure considers IOLs having a diopter shape factor less than or equal to -1 and / or IOLs having a diopter shape factor greater than or equal to -1. The lens body of an IOL having a diopter shape factor less than or equal to -1 may be formed differently from the lens body of an IOL having a diopter shape factor greater than or equal to -1. This disclosure can provide a set of lenses including at least one first lens having a diopter shape factor less than or equal to -1. Additionally or alternatively, the set of lenses may include at least one second lens having a diopter shape factor greater than or equal to -1. Lenses having a diopter shape factor less than or equal to -1 and / or lenses having a diopter shape factor greater than or equal to -1 may have a refractive index (n2) between 1.40 and 1.50 and / or between 1.50 and 1.60. Other refractive index ranges are considered. The refractive index can be between 1.45 and 1.48. The refractive index can be between 1.54 and 1.56. The refractive index can be 1.471. The refractive index can be 1.55. The corresponding power shape factor and radius of curvature for different refractive indices correspond to the pattern established for the lenses described above. In fact, the differences and similarities between the power shape factors of the lenses described above indicate patterns that can be used to predict lens characteristics, such as, but not limited to, the dome height as described above. These same effects can be demonstrated in further testing of lenses with variable refractive index values ​​disclosed herein.

[0061] This disclosure describes the structural factors of an IOL, which, according to the optimizations described herein, demonstrates superior results in foveal and peripheral visual acuity after implantation. Lenses with a shape factor of less than or equal to -1

[0062] As stated above, and as Figures 4 to 7 As shown, certain lower label powers, such as lenses with a power shape factor less than or equal to -1, exhibit less stable power shape factor values ​​within the lower label power range. The lower label power range can be from 7D to 17D. For example... Figures 4 to 7 Furthermore, for lenses with a power shape factor less than or equal to -1, similar uncertainty is observed at higher label powers above 28D and below 36D. This provides a basis for fine-tuning the front and rear surface curvatures of each lens at each label power. Since the center thickness, dome height, and shape factor are selected within the range described in this disclosure, the front and rear surface curvatures can be adjusted to produce peripheral vision lenses with a stable power response across the label power range. Figure 4As shown in graph 400, for IOLs with a degree shape factor less than or equal to -1 and a refractive index between 1.40 and 1.50, the degree response is stable in the range of 17D to 23D. (Reference) Figure 5 The curve 500 shows that for IOLs with a power shape factor less than or equal to -1 and a refractive index between 1.50 and 1.60, the stable range of labeled power is between 20D and 28D. Lenses with these labeled ranges have an easily predictable ability to optimize coaxial visual acuity as close as possible to the boundaries of diffraction-limited performance, while correcting peripheral vision.

[0063] An embodiment of a peripheral vision IOL includes a lens body. The lens body has a refractive power label between 17D and 23D, and a refractive index value between approximately 1.40 and 1.50. For these label values ​​and refractive indices, the power shape factor is between -1 and -2.5. The first surface may have a diameter of -0.77 mm. -1 With 0.00mm -1 The curvature of the front surface between them. The second surface can have -0.355mm. -1 With -0.130mm -1 The curvature of the posterior surface is between 0.62 mm and 1.0 mm. The central thickness can be between 0.62 mm and 1.0 mm. The anterior tactile part can be connected to the lens body to fix the lens in place after implantation, and the IOL can present an arch height between 0.34 mm and 0.65 mm.

[0064] For embodiments of lens bodies with a refractive index between approximately 1.50 and 1.60 and a diopter label between 20D and 28D, the power shape factor is between -1 and -3. The first surface may have a diameter of -0.022 mm. -1 With 0.00mm -1 The curvature of the front surface between them. The second surface can have -0.170mm. -1 With -0.081mm -1 The curvature of the posterior surface is between 0.45 mm and 1.0 mm. The central thickness can be between 0.45 mm and 1.0 mm. The anterior tactile part can be connected to the lens body to fix the lens in place after implantation, and the IOL can present an arch height between 0.30 mm and 0.65 mm.

[0065] An IOL (In-Loop Lens) may be provided, comprising a lens body manufactured according to a sub-range of labeled power and power shape factor. For lenses with a refractive index between approximately 1.40 and 1.50, the labeled power sub-range may be 18D and 22D, and for lenses with a refractive index between 1.50 and 1.60, the labeled power sub-range may be between 20D and 27D. (Reference) Figure 6 and Figure 7The narrow bands 610 and 710 of the optimization functions within these sub-ranges indicate that lenses with labeled diopters within the sub-ranges have an even more stable shape factor across this range compared to the wider range described above. This stability means it is easier to predict which structural features will cause the lens to minimize off-axis astigmatism at a 20-degree eccentricity while maximizing coaxial visual acuity according to the optimized MTF described in this application.

[0066] In one embodiment, the lens has a diopter label between 18D and 22D, and a refractive index value between approximately 1.40 and 1.50. The lens's shape factor is between -1.1 and -2.0. In this case, the first surface may have a front surface curvature, or at -0.071 mm. -1 With -0.00mm -1 Between. The second surface can have -0.355mm. -1 With -0.134mm -1 The curvature of the posterior surface between [the two points]. The center thickness of the lens can be between 0.70 mm and 0.90 mm. After implantation, the anterior tactile part can be connected to the lens body to fix the lens in place, and the IOL can present an arch height between 0.40 mm and 0.60 mm.

[0067] Another embodiment of the lens has a diopter label between 20D and 27D and a refractive index between approximately 1.50 and 1.60. In this case, the lens's power shape factor is between -1.0 and -2.4. The first surface may have a diameter of -0.022 mm. -1 With -0.00mm -1 The curvature of the front surface between them. The second surface can have -0.170mm. -1 With -0.084mm -1 The curvature of the posterior surface between [the two points]. The center thickness can be between 0.55 mm and 0.90 mm. After implantation, the anterior tactile part can be connected to the lens body to fix the lens in place, and the IOL can present an arch height between 0.35 mm and 0.60 mm. Lenses with a shape factor of power greater than or equal to -1

[0068] As described above, for an IOL with a label power greater than the inflection point power, the intraocular lens includes a lens body that can be formed differently from the lens body of an IOL with a label power less than the inflection point power. The inflection point power can be the label power corresponding to an IOL with a shape factor of -1. For example, refer to... Figure 4 For lenses with a refractive index between 1.40 and 1.50, the transition point power can be 23D, 24D, or 25D. (Refer to...) Figure 5For lenses with a refractive index between 1.50 and 1.60, the transition point power can be 23D, 25D, or 28D. Other transition point powers can be selected appropriately.

[0069] For higher values ​​of the labeled power for lenses with a power shape factor greater than or equal to -1, the rate of increase of the power shape factor across the labeled power range will vary, but the difference will be smaller compared to the labeled power values ​​below the transition point discussed earlier. (Refer to...) Figure 4 Between certain increases in labeled power, the rate of increase in the power shape factor across the labeled power range exhibits small variations. For lenses with a power shape factor greater than or equal to -1 and a refractive index between 1.40 and 1.50, these labeled power ranges can be between 23D and 30D; or for lenses with a power shape factor greater than or equal to -1 and a refractive index between 1.50 and 1.60, these labeled power ranges can be between 23D and 25D. Within these ranges, the anterior and posterior surface curvatures can be refined to produce easily predictable changes in shape factor across the entire range. This stability improves the ability to predict structural features that allow the lens to correct peripheral vision while optimizing coaxial visual acuity.

[0070] Examples of lenses have a diopter label between 23D and 30D and a refractive index value between approximately 1.40 and 1.50. The diopter shape factor is between -0.2 and -1. For these ranges, the first surface can have a 0mm diameter. -1 With 0.120mm -1 The curvature of the front surface between them. The second surface can have -0.367mm. -1 With -0.130mm -1 The curvature of the posterior surface is between 0.62 mm and 1.0 mm. The central thickness can be between 0.62 mm and 1.0 mm.

[0071] Examples of lenses with a refractive index between approximately 1.50 and 1.60 have a diopter label between 23D and 35D. The diopter shape factor is between -0.2 and -1. In this case, the first surface may have a diameter of 0.00 mm. -1 With 0.082mm -1 The curvature of the front surface between them. The second surface can have -0.179mm. -1 With -0.081mm -1 The curvature of the posterior surface is between 0.45 mm and 1.0 mm. The central thickness can be between 0.45 mm and 1.0 mm. The anterior tactile part can be connected to the lens body to fix the lens in place after implantation, and the IOL can present an arch height between 0.30 mm and 0.65 mm.

[0072] Within at least one example sub-range, such as Figure 6 As shown in region 620, for lenses with a power shape factor greater than or equal to -1 and a refractive index between 1.40 and 1.50, between 24D and 29D, or as... Figure 7 As shown in region 720, for lenses with refractive indices between 1.50 and 1.60, between 25D and 35D, the rate of increase in the power shape factor is determined such that the difference is not statistically significant, and the power shape factor appears to exhibit even greater stability. These sub-ranges can be selected to optimize the structural characteristics of the IOL, thereby minimizing off-axis astigmatism and maximizing coaxial visual acuity at a 20-degree eccentricity, thus improving peripheral vision. Based on this optimization disclosed herein, an IOL comprising a lens body manufactured according to the following labeled power and power shape factor sub-ranges can be provided to maximize coaxial visual acuity while minimizing off-axis astigmatism at a 20-degree eccentricity.

[0073] Another embodiment of the lens has a diopter label between 24D and 29D, a refractive index between approximately 1.40 and 1.50, and a shape factor between -0.3 and -0.8. In this case, the first surface may have 0mm. -1 With 0.12mm -1 The curvature of the front surface between them. The second surface can have a curvature of 0.36 mm. -1 With 0.13mm -1 The curvature of the posterior surface between [the two points]. The center thickness of the lens can be between 0.70 mm and 0.90 mm. After implantation, the anterior tactile part can be connected to the lens body to fix the lens in place, and the IOL can present an arch height between 0.40 mm and 0.60 mm.

[0074] Examples of lenses with diopter labels between 25D and 35D and refractive index values ​​between approximately 1.50 and 1.60 have a power shape factor between -0.7 and -0.95. In this case, the first surface may have a diameter of 0.01 mm. -1 With 0.082mm -1 The curvature of the front surface between them. The second surface can have -0.179mm. -1 With -0.081mm -1 The curvature of the posterior surface between [the two points]. The center thickness of the lens can be between 0.55 mm and 0.90 mm. After implantation, the anterior tactile part can be connected to the lens body to fix the lens in place, and the IOL can present an arch height between 0.35 mm and 0.60 mm. Lens group

[0075] A set of lenses may be provided, comprising at least one lens having a power shape factor less than or equal to -1 as defined above, and / or at least one lens having a power shape factor greater than or equal to -1 as defined above. This set of lenses may include a series of lenses. The diopter label of each lens in this series may vary by at least 0.25D compared to the other lenses in the series. For example, the series may include five lenses with diopter labels of 17.5D, 17.75D, 18D, 18.25D, and 18.5D. The diopter label of each lens in this series may vary by 0.5D, 1D, 2D, 3D, 4D, or 5D compared to the other lenses in the series. The lenses in this set may have label diopters below or above the transition point diopter. A lens body for an IOL with a label power higher than the transition point power can be formed differently from a lens body for an IOL with a label power lower than the transition point power. The transition point power is the label power corresponding to an IOL with a form factor of -1. For example, refer to... Figure 4 For lenses with a refractive index between 1.40 and 1.50, the transition point power can be 23D, 24D, or 25D. (Refer to...) Figure 5 For lenses with a refractive index between 1.50 and 1.60, the transition point power can be 23D, 25D, or 28D. Other transition point powers can be selected appropriately.

[0076] In addition to providing peripheral vision correction for prescriptions requiring a refractive power greater than the inflection point, providing a set of lenses also allows for peripheral vision correction for prescriptions requiring a refractive power less than the inflection point. Therefore, embodiments of the lens set of the present invention allow for peripheral vision correction across the entire range of possible prescriptions. Advantageously, this set can provide a series of lenses that the user can select to customize the chosen lens according to the patient's refractive power requirements.

[0093] This disclosure uses a range of power shape factors to further illustrate how a lens according to this disclosure can have a range of structural values ​​that ensures normal function and enhances peripheral vision when implanted in a patient.

[0094] It is also envisioned that any lens disclosed herein can also correct the mean corneal spherical aberration specified in ISO 11979-2 2014, Eye Model #2. Industrial applications

[0095] A method for designing a set of intraocular lenses to improve peripheral vision can be provided. The method may include providing an IOL with an optical power that reduces optical errors in the image generated at a peripheral retinal location of the patient's eye at a distance from the fovea. An IOL can be provided in increments of 0.25D from 17D to 35D. As the labeled power of the lens increases from 17D to 35D, the power shape factor increases from -3.0 to -0.2. For labeled powers corresponding to shape factors below the transition point power, the IOL includes a first lens body having a power shape factor less than or equal to -1 according to the above embodiment. For labeled powers corresponding to shape factors above the transition point power, the IOL includes a second lens body having a power shape factor greater than or equal to -1 according to the above embodiment. Each IOL may have a blur parameter of less than 1.8D.

[0096] Other methods for designing a set of lenses are envisioned within the scope of this disclosure.

[0097] In addition to other variable, non-uniform surface structures for the anterior and posterior surfaces of the lens body, the intraocular lens according to this disclosure can also utilize complex surfaces, such as Zernike surfaces and toroidal surfaces. In a non-limiting embodiment of the IOL, a first surface has an anterior radius and presents an anterior power; a second surface has a posterior radius and presents a posterior power. At least one of the first or second surfaces can be a complex surface. The intraocular lens presents a power shape factor relative to a constant plano-convex power shape factor and corresponds to a refractive power label power, wherein the power shape factor includes a first power value calculated using the anterior and posterior radii, and a second power value calculated using the anterior and posterior powers. The first and second power values ​​can have equal or different values ​​for the corresponding refractive power label power. At least one of the first or second surfaces has a refractive profile. Therefore, a complex surface can use variable anterior and posterior radius values ​​and a variable first power value. The complex surface may further include a verified power shape factor that only has a second power factor calculated using the anterior and posterior powers. In embodiments, at least one of the first or second surfaces includes a toric surface. The shape factor of the intraocular lens has a tortuous surface with an average value of the diopter meridians calculated for different portions of the intraocular lens surface. In another embodiment, additional diopter values ​​can be added to the diopter label, wherein the shape factor remains equal to a second diopter value calculated using the base anterior and base posterior diopters.

[0098] In another embodiment of the intraocular lens according to this disclosure, the IOL has an anterior radius and a first surface exhibiting an anterior power and a second surface having a posterior radius and exhibiting a posterior power. Optionally, at least one of the first or second surfaces is a complex surface having multiple curvatures across the surface. Similar to the other lenses described above, the intraocular lens exhibits a power shape factor relative to a constant plano-convex power and corresponding to a label power measured in refractive power. The power shape factor may have a first power value calculated using the anterior and posterior radii, and a second power value calculated using the anterior and posterior powers. The first and second power values ​​may have different values ​​for the corresponding refractive power label power. In a non-limiting lens according to this disclosure, the complex surface may have variable anterior and posterior radius values ​​and a variable first power value. The complex surface may also include a verification power shape factor calculated only using the second power factor, which in turn is calculated using the total anterior surface power and the total posterior surface power, wherein the total power takes into account different radii of curvature. In some embodiments, at least one of the first or second surfaces includes a torus (i.e., at least a portion of the surface presents a torus or ring). The power shape factor of an intraocular lens with a torus can be the average of the power meridians calculated for different portions of the intraocular lens. In some cases, the IOL of this disclosure has an additional power added to the label power, wherein the power shape factor remains equal to a second power value calculated using the base anterior power and the base posterior power.

[0099] In some cases, this disclosure describes comparable relationships between optical components in terms of position or operating parameters. These descriptions are not intended to limit this disclosure, but are presented for illustrative purposes only. In fact, when this disclosure uses numerical values ​​to represent dimensions or ranges, all numerical values ​​are to be understood as “approximately” or “roughly equal”, and these phrases should be given the broadest common meaning in the technical context. In some embodiments, the magnitude of certain optical parameters may be “approximately” a certain value, or may be “roughly equal” if the magnitudes differ from each other by an amount selected from 0-5% of the larger value. Unless otherwise specified or unless the context of the range specifies otherwise, ranges in this disclosure include endpoints.

[0100] In addition to the background discussion above, this disclosure also incorporates some contextual information regarding example structures of IOLs, the optical effects of these structures on patient vision, and the environments in which IOLs are successfully used. As would be expected, numerous diagnostic steps occur before a physician prescribes an IOL to a patient. Measurements of the patient's eye can be performed in a clinical setting, such as by an optometrist, ophthalmologist, or other medical or optical professionals. Measurements can be performed via explicit refraction, automated refraction, tomography, or a combination of these methods, or other measurement methods. Optical aberrations of the patient's eye can also be determined.

[0101] It can also determine the patient's visual range. For example, it can measure and determine the patient's ability to focus on nearby objects (presbyopia). It can also determine the range of lens power required for ophthalmic lenses.

[0102] Measurements of the patient's eye can be included in an ophthalmic lens prescription that includes features of at least one optical element designed to address optical aberrations in the patient's eye, as well as features that address the patient's visual range (e.g., the amount of diopter and number of focal points provided by the optics).

[0103] Ophthalmic lens prescriptions can be used to manufacture optics for ophthalmic lenses. The refractive profile of the optics can be determined based on the ophthalmic lens prescription to correct optical aberrations in the patient's eye. This refractive profile can be applied to the optics, whether on a surface including the diffraction profile or on the opposite optical surface. The diffraction profile can also be determined to provide the desired power distribution for the optics.

[0104] The determination of one or more of the refractive or diffractive profiles and the manufacture of the optical device can be performed remotely with an optometrist, ophthalmologist, or other medical or optical professional who takes measurements of the patient's eye, or can be performed in the same clinical facility as such an individual. If performed remotely, the manufactured optical device can be delivered to the optometrist, ophthalmologist, or other medical or optical professional for use with the patient. For intraocular lenses, the manufactured optical device can be provided for implantation in the patient's eye. The manufactured optical device can be manufactured according to embodiments of this disclosure.

[0105] The manufactured optics can be custom-made optics specifically for the patient's eyes, or they can be manufactured in a manufacturing assembly and then selected by an optometrist, ophthalmologist, or other medical or optical professional to be supplied to the patient, which may include implantation in the patient's eyes.
