Description

Technical Field

[0001] This invention generally relates to optical systems. More particularly, this invention relates to a telescopic method based on an intraocular intraocular lens contact lens (IOPCL) for treating age-related macular degeneration (AMD) or other eye diseases. Background Technology

[0002] Age-related macular degeneration (AMD) causes degeneration of the macula in the retina of the eye. The retina is a paper-thin tissue at the back of the eye where photoreceptor cells send visual signals to the brain, and the macula supports fine vision. Sharp, clear, and direct vision is centered on the macula; damage to the macula results in central blind spots of various sizes and blurred or distorted central vision. People affected by AMD find that as the disease progresses, many daily activities, such as driving and reading, become increasingly difficult and eventually impossible. Common difficulties and symptoms of AMD include loss of the ability to drive a car, loss of reading ability, distorted or lost central vision, progressively decreased contrast sensitivity, increased glare and light sensitivity, the need for additional lighting for reading, and impaired depth perception.

[0003] AMD is a leading cause of vision impairment and irreversible vision loss. AMD is more common in people aged 50 and older, and it is one of the leading causes of legally recognized blindness. Up to 15 million Americans currently have some type of AMD, including both early and intermediate stages. This number is projected to increase to nearly 22 million by 2050. It is estimated that more than 196 million people worldwide have AMD to varying degrees, and this number is expected to increase to 288 million by 2040. Risk factors for developing AMD include a positive family history, smoking, farsightedness, light-colored eyes, high blood pressure, and cardiovascular disease. Summary of the Invention

[0066] The following discussion Figures 1 to 15 The various embodiments used to describe the principles of the invention in this patent document are merely exemplary and should not be construed as limiting the scope of the invention in any way. Those skilled in the art will understand that the principles of the invention can be implemented in any type of suitably arranged apparatus or system.

[0067] This invention relates to devices, systems, and techniques for treating age-related macular degeneration (AMD) or other types of eye diseases using the Galileo vision system. The Galileo vision system includes an intraocular intraocular lens contact lens (IOPCL) that can be mounted on, attached to, or otherwise fixed to an artificial intraocular lens (IOL) for one or more eyes of a patient. The Galileo vision system also includes one or more external lenses (such as eyeglasses (lenses) or contact lenses) having a specially designed magnification system to magnify images onto the macula(s) of the patient's eye(s). The IOPCL-based Galileo magnification approach can be particularly used to provide customized vision systems for treating early and intermediate AMD in patients with intraocular lenses. For example, these patients may have lost enough vision to support maintaining their driving privileges. They may also have genuinely lost their ability to drive and / or read normal printed materials.

[0068] Figure 1 and Figure 2 An example Galileo vision system 100 according to the present invention is illustrated. Figure 1 and Figure 2 As shown, the Galileo visual system 100 is used in conjunction with a patient's eye 102. Depending on the circumstances, a single Galileo visual system 100 may be used for one of the patient's eyes 102, or two Galileo visual systems 100 may be used for both of the patient's eyes 102. The eye 102 generally comprises a cornea 104, a sclera 106, and an iris 108. For ease of illustration and explanation, the eye 102 itself... Figure 1 The image is shown in cross-sectional form. The cornea 104 represents the transparent anterior portion of the eye 102 through which light enters the eye 102. The sclera 106 represents the hard, outer white portion of the eye 102. The iris 108 represents a component of the eye 102 that controls the size of the pupil, thereby controlling the amount of light entering the eye 102 from the cornea 104.

[0069] Eye 102 also includes a capsule 110 that normally holds the natural lens of eye 102. However, in this example, the natural lens has been removed and replaced with an artificial intraocular lens (IOL) 112. The IOL 112 generally comprises an optical lens and one or more tactile elements. The optical lens of the IOL 112 receives light entering eye 102 and focuses it onto the retina of eye 102. The tactile elements of the IOL 112 help hold the IOL 112 within the capsule 110, ensuring that the optical lens of the IOL 112 is in the desired position within the eye. Eye 102 in which the natural lens has been replaced by the artificial intraocular lens 112 is generally referred to as an "artificial lens" eye. It should be noted that a wide variety of artificial intraocular lenses are available for use with patients, and other artificial intraocular lenses will certainly be developed in the future. The intraocular lens 112 shown herein is for illustrative purposes only, and any other suitable artificial intraocular lens now known or developed in the future may be used in the Galileo vision system 100. In addition, the intraocular lens 112 can be used here to provide any desired optical correction or other modification of the light passing through the eye 102.

[0070] An intraocular intraocular lens (IOPCL) 114 is placed on or otherwise positioned in front of the intraocular lens 112 (possibly without contact with the uvea). The IOPCL 114 represents another lens that can be mounted on, attached to, or otherwise fixed to the intraocular lens 112. As shown here, the IOPCL 114 can be positioned on or in front of the anterior surface of the intraocular lens 112, meaning the anterior surface of the intraocular lens 112 relative to the eye 102. Light enters through the cornea 104 and passes through the pupil before entering the IOPCL 114, which modifies the light. The modified light then passes through the optical lens of the intraocular lens 112 and is modified again. The twice-modified light then passes through the rest of the eye 102 to reach the retina at the back of the eye 102.

[0071] As described below, the intraocular intraocular lens contact lens 114 includes an optical lens and optional mechanisms for securing the intraocular intraocular lens contact lens 114 to or against the intraocular lens. For example, in some embodiments, the intraocular intraocular lens contact lens 114 includes one or more tactile elements that extend a short distance and are positioned below the anterior leaf of the capsular bag 110 in the eye 102. This allows the tactile elements to be captured and confined by the anterior leaf and may be attached to the capsular wall of the anterior leaf via fibrosis or refibrillation. The anterior leaf refers to the outer portion of the anterior side of the capsular bag 110, which forms an opening (referred to as capsulotomy) in the capsular bag 110 so that the natural lens can be retained after removal. Inserting the tactile element of the intraocular intraocular lens contact lens 114 under the anterior leaf helps to secure the intraocular intraocular lens contact lens 114 in place. In some cases, the healing process in eye 102 may lead to fibrosis or refibrosis, which could also affect the tactile aspect of the anterior leaflet attached to the intraocular lens contact lens 114. In other embodiments, the intraocular lens contact lens 114 includes one or more needles capable of piercing the lens material of the intraocular lens 112. In other embodiments, the intraocular lens contact lens 114 may be designed to mate with or connect to one or more components of the intraocular lens 112 specifically designed for use with the intraocular lens contact lens 114. Generally, any suitable mechanism(s) can be used to mount, attach, or otherwise secure the intraocular lens contact lens 114 in place relative to the intraocular lens 112.

[0072] An external lens 116 is positioned in front of the eye 102. In this example, the external lens 116 takes the form of an eyeglass lens (such as a spectacle lens) that can be held in the proper position in front of the eye 102 (such as using a patient-worn frame). However, the external lens 116 can also take other forms, such as a contact lens 116' worn on the cornea 104 of the eye 102. The external lens 116 and the intraocular intraocular lens contact lens 114 (with or without the intraocular lens 112) form the Galileo vision system 100. More specifically, the Galileo vision system 100 is formed using two high-power optics with opposite optical powers. The intraocular intraocular lens contact lens 114 contains a high-negative-power optical segment implanted in the eye 102. The high-negative-power segment of the intraocular intraocular lens contact lens 114 produces a large hyperopic refractive error in a portion of the patient's visual field while maintaining the patient's current hyperopic visual field and peripheral visual acuity. In some embodiments, the high negative power segment of the intraocular intraocular lens contact lens 114 can serve as the "eyepiece" of the Galilean telescope system.

[0073] To complete the Galilean telescope system, an external lens 116, such as a high-positive-power spectacle lens, contact lens, or other external lens, is placed in front of the eye 102. The high positive power makes the external lens 116 essentially function as the objective lens of the Galilean telescope system. The high-positive-power lens can be manufactured in any suitable manner. For example, in some cases, the high-positive-power lens can be manufactured using a diffraction phase plate made by a specialized eyewear manufacturer to achieve very high positive power while maintaining minimal weight and thickness. Using specialized corrective lenses can help avoid the problems encountered in existing methods. Furthermore, when a patient's vision gradually deteriorates over time due to the progression of AMD or other impairments, using specialized corrective lenses allows for subsequent adjustments to the magnification effect. However, other techniques for manufacturing the external lens 116 can be used.

[0074] Depending on the implementation, the intraocular intraocular lens contact lens 114 can be multifocal and include combinations of lens powers (such as high negative power optical segments and optical segments with different or no powers). This allows observation to be performed with or without the complete Galileo vision system 100 as needed. This means that, even without the external lens 116 in place and only with the intraocular intraocular lens contact lens 114 in place, a patient may be able to enjoy the benefit of increased magnification (such as approximately 1.4x to 1.6x magnification). This level of magnification may be sufficient to restore a patient whose vision has decreased from 20 / 40 distance corrected distance visual acuity (DCDVA) to 20 / 60 best corrected distance visual acuity (BCDVA) to approximately 20 / 40 BCDVA. This is sufficient to read normal-sized printed materials or regain a patient's driver's license. With the external lens 116 in place along with the intraocular intraocular lens contact lens 114, the Galileo vision system 100 can achieve even greater magnification. Therefore, among the various methods, patients can benefit from both normal width and magnification of their field of vision (with external lens 116 not in the proper position) and greater magnification (with external lens 116 in the proper position).

[0075] Although often described as being for treating both eyes 102 of a patient, this is not mandatory. For example, a single eye 102 of the patient can be treated, and a contact lens, spectacle, or other external lens 116 can be used with that eye 102 to provide a Galilean telescope system for that eye 102. The patient's other eye 102 may not have a contact lens, spectacle, or other external lens 116, or the other eye 102 may contain a different contact lens, spectacle, or other external lens 116 (it may be blank or uncorrected). The patient's other eye 102 may or may not contain an intraocular intraocular lens contact lens 114, and it is not required that the other eye 102 contain the same type of intraocular intraocular lens contact lens 114. In general, the methods described herein can be readily customized to provide the desired correction for each patient's (one or both) eyes 102, individually or collectively.

[0076] The desired optical power of the intraocular intraocular lens contact lens 114 and the external lens 116 can be achieved in any suitable manner. For example, in some embodiments, the segmented optical power of the intraocular intraocular lens contact lens 114 can be delivered in a central aperture or dedicated segmented region of different powers or shapes on the posterior or anterior side of the optics of the intraocular intraocular intraocular lens contact lens 114. The external lens 116 can also have any suitable anterior and posterior surfaces that provide the desired optical power.

[0077] although Figure 1 and Figure 2 An example of the Galileo vision system 100 is illustrated, but it is possible to... Figure 1 and Figure 2 Various modifications can be made. For example, any suitable intraocular contact lens 114 (with or without the intraocular lens 112) and any suitable external lens 116 can be used to form the Galilean visual system 100.

[0078] Figures 3 to 9 An example intraocular intraocular lens contact lens 300 for the Galilean vision system according to the present invention is illustrated. More specifically, Figure 3 The illustration shows a perspective view of the intraocular intraocular lens contact lens 300. Figure 4 The illustration shows a top view of the intraocular intraocular lens contact lens 300, and... Figure 5 The illustration shows a side view of the intraocular intraocular lens contact lens 300. Figures 6 to 9 The illustration shows different cross-sectional views of the intraocular intraocular lens contact lens 300. For ease of explanation, the intraocular intraocular lens contact lens 300 can be described as representing the intraocular intraocular intraocular lens contact lens 114 and used for... Figure 1 and Figure 2In the Galileo vision system 100. However, the intraocular intraocular lens contact lens 300 can be used in any other suitable Galileo vision system, and the Galileo vision system can use any other suitable type of intraocular intraocular lens contact lens.

[0079] like Figures 3 to 5 As shown, the intraocular intraocular lens contact lens 300 includes an optical lens 302 that represents a portion of the light passing through the intraocular intraocular lens contact lens 300 that alters the composition of the light. For example, light passing through the optical lens 302 can then pass through the associated intraocular lens 112 before reaching the retina of the patient's eye 102. The optical lens 302 can be formed from any suitable material(s) such as silicone or acrylic. The optical lens 302 can also be formed in any suitable manner (such as by using a mold, laser, or lathe cutting process). Different optical lenses 302 in different intraocular intraocular lens contact lenses 300 can be designed and manufactured to provide different types of optical modifications, such as when different optical lenses 302 provide different high negative power optical magnification.

[0080] Multiple tactile elements 304a-304c extend from multiple sides of the optical lens 302. The size and shape of the tactile elements 304a-304c are designed such that they extend a short distance from the optical lens 302 and, after implantation, are positioned beneath the anterior leaf of the capsular wall in the patient's eye 102. Each tactile element 304a-304c can be made of any suitable material(s) and formed in any suitable manner. For example, each tactile element 304a-304c can be formed of the same material(s) as the optical lens 302. It should be noted that although three tactile elements 304a-304c are shown herein, the intraocular intraocular lens contact lens 300 can contain any number of tactile elements, including a single tactile element. It should also be noted that although the tactile elements 304a-304c are angled downwards (meaning that the tactile elements 304a-304c generally extend outwards and backwards from the optical lens 302), the tactile elements 304a-304c can have any other suitable arrangement. Furthermore, it should be noted that the tactile elements 304a-304c can be coupled to the optical lens 302 in any suitable manner, such as when the tactile elements 304a-304c are integrally formed with the optical lens 302 or attached to the optical lens 302 or a retaining ring or other structure (integrated with or attached to the optical lens 302) using adhesives or other suitable coupling mechanisms.

[0081] Each of the tactile elements 304a-304c may include a textured surface 306 that facilitates the capture or restriction of the tactile elements 304a-304c by means of the anterior leaf of the capsule wall in the patient's eye 102. This particularly helps the tactile elements 304a-304c to hold the intraocular intraocular lens contact lens 300 to or in place of the intraocular lens 112. In some cases, the textured surface 306 allows the tactile elements 304a-304c to be physically bonded to the anterior leaf of the capsule wall in the patient's eye 102, such as through fibrosis or refibrosis during healing. In other cases, the textured surface 306 can simply resist movement of the tactile elements 304a-304c relative to the anterior leaf of the capsule wall in the patient's eye 102.

[0082] Each textured surface 306 represents any suitable structure that facilitates the restriction, capture, or attachment of haptic elements 304a-304c to the anterior leaf of the capsule wall. In some cases, each textured surface 306 may represent an electrical discharge machining (EDM) finish, or each textured surface 306 may represent a hole formed partially or completely through the haptic elements 304a-304c (in which case the number and size of the holes in the textured surface 306 may vary as needed or desired). It should be noted that other forms of texture may be used herein, or texture may be unnecessary. It should also be noted that haptic elements 304a-304c may be omitted if not needed, such as when the intraocular intraocular lens contact lens 300 can be held in place on the intraocular lens 112 by surface tension, adhesives, or other techniques. Furthermore, it should be noted that other types of tactile elements can be used with the intraocular lens contact lens 300, or pins embedded in or passing through the optical lens of the intraocular lens contact lens 300 or other structures of the intraocular lens contact lens 300 can be used to secure the intraocular lens contact lens 300 to the intraocular lens 112. Generally, the present invention is not limited to any particular tactile element design or mechanism for mounting or attaching the intraocular lens contact lens 300 to or onto the intraocular lens 112.

[0083] In this example, the tactile elements 304a-304c of the intraocular intraocular lens contact lens 300 are formed as large protrusions extending from the side of the optical lens 302, effectively forming long "wings" extending from the optical lens 302. In this example, the interior of each tactile element 304a-304c protrudes outward and downward (rearward), and in this example, the outer portion of each tactile element 304a-304c protrudes outward and slightly upward (although the outer portion of each tactile element 304a-304c can be flexible, as described below). However, it should be noted that other forms of the tactile elements 304a-304c can also be used. Each of the outer portions of the tactile elements 304a-304c has a thickness that gradually decreases towards the outer edge of the tactile element 304a-304c, which facilitates easier insertion of the tactile elements 304a-304c into the anterior leaf of the capsule wall in the patient's eye 102. The lower surface of the tactile elements 304a-304c also includes ridges 308, and the ridges 308 of the plurality of tactile elements 304a-304c can be used to capture one or more edges of the underlying intraocular lens 112. This can help center the intraocular intraocular lens contact lens 300 on the intraocular lens 112. This can also help maintain the intraocular intraocular lens contact lens 300 in the proper position on the intraocular lens 112 during the healing process or during use. Although the ridges 308 are shown here as generally flat or slightly curved, the ridges 308 can be combined with other features. For example, a lip can be formed by extending inward from the bottom of the ridge 308 or one or more other portions toward the central optical axis of the optical lens 302 (meaning...). Figure 5 A small, inwardly protruding portion is formed, extending from the vertical axis passing through the center of the optical lens 302.

[0084] The tactile elements 304a-304c can be located in any suitable position within the intraocular lens contact lens 300. For example, in some embodiments, the tactile elements 304a-304c are uniformly spaced about 120° apart. In other embodiments, the tactile elements 304a-304c are not uniformly spaced, such as when tactile element 304a is separated from each of the tactile elements 304b-304c by about 125° and the tactile elements 304b-304c are separated from each other by about 110° (this can be based, for example, on the position of the tactile elements of the intraocular lens 112 on which the intraocular lens contact lens 300 will be placed). Furthermore, in some cases, the intraocular lens contact lens 300 can be designed to be implanted in a patient's eye 102 with a specific orientation, and at least one alignment mark 310 can be provided to identify the correct orientation of the intraocular lens contact lens 300 in the eye 102. In this example, a single alignment mark 310 in the form of a raised letter "R" can be used to identify the tactile element 304a to be positioned to the right of the intraocular lens 112 when a surgeon or other person observes the intraocular lens 112 within the eye 102. However, any other or additional alignment mark 310 may be used, or no alignment mark may be used at all.

[0085] Depending on the implementation, the optical lens 302 can have any suitable optical power(s). In this example, the optical lens 302 includes a first lens portion 312 and a second lens portion 314, wherein the two portions 312-314 of the optical lens 302 can provide different levels of optical magnification. For example, the first lens portion 312 can provide a specified amount of magnification (such as high negative optical power magnification), and the second lens portion 314 can provide a different amount of magnification or may have very little or no magnification. To provide high negative optical power in this example, the front surface of the first lens portion 312 can be convex or concave, and the rear surface of the first lens portion 312 can be concave. The amount of high negative optical power magnification can be adjusted by changing the shape of one or more of the front and rear surfaces of the first lens portion 312. For example, Figures 6 to 9 The diagram illustrates along Figure 4 The example cross-section of the intraocular intraocular lens contact lens 300, taken by line AA, shows different first lens portions 312a-312d having different shapes on their anterior surfaces. These different shapes allow the different first lens portions 312a-312d to provide different amounts of high negative optical power magnification. As a specific example, lens portion 312a can provide -15 diopters of optical power, lens portion 312b can provide -20 diopters of optical power, lens portion 312c can provide -25 diopters of optical power, and lens portion 312d can provide -5 diopters of optical power (although these are only example values).

[0086] Therefore, the first lens portion 312 in the intraocular intraocular lens contact lens 300 can be used to provide a large amount of negative optical magnification. This supports the use of the intraocular intraocular lens contact lens 300 in the Galileo vision system 100, where the outer lens 116 can provide a large amount of positive optical magnification. The second lens portion 314 in the intraocular intraocular lens contact lens 300 can be used to provide a different amount of optical magnification or no optical magnification. For example, the anterior surface of the second lens portion 314 can be convex, and the posterior surface of the second lens portion 314 can be concave. Therefore, the central segment of the optical lens 302 shown herein can be used to increase the field of vision, such as increasing it to the intermediate or near. This can be used to help treat conditions such as AMD or other vision loss associated with retinal diseases.

[0087] In this particular example, the first lens portion 312 is generally circular and positioned at the center of the intraocular intraocular lens contact lens 300, and the second lens portion 314 is generally annular and surrounds the first lens portion 312. However, each lens portion 312 and 314 may have any other suitable size, shape, and position within the intraocular intraocular lens contact lens 300. Generally, the size, shape, and position of the lens portions 312-314 can be varied as needed or desired to provide the desired optical magnification.

[0088] Figures 3 to 9The intraocular lens contact lens 300 shown can be easily attached to the intraocular lens 112, such as by capturing and confining the tactile elements 304a-304c of the intraocular lens contact lens 300 using the anterior leaf of the capsule wall in the eye 102. In some cases, this may also involve the physical bonding of the tactile elements 304a-304c to the anterior leaf of the capsule wall, such as via fibrosis or refibrosis mechanisms. Therefore, in some embodiments, the intraocular lens contact lens 300 may not need to be designed to work specifically with any particular structure of the intraocular lens 112. Instead, the intraocular lens 112 used with the intraocular lens contact lens 300 does not need to have any predetermined structure provided for attachment to the intraocular lens contact lens 300. Instead, the size of the intraocular lens contact lens 300 can be simply designed such that when the intraocular lens contact lens 300 is placed on the intraocular lens 112, it can be secured in place by being captured and restrained (and possibly combined with) the anterior leaflet of the capsule wall. This allows the intraocular lens contact lens 300 to be used with a wide variety of intraocular lenses 112 (including different types of intraocular lenses 112 and existing intraocular lenses 112 already implanted in the patient). It is not necessary to remove the existing intraocular lens 112 from the patient for the purpose of installing a new intraocular lens and intraocular lens contact lens. However, it should be noted that in other embodiments, the intraocular lens contact lens may also be designed specifically to mate with a particular intraocular lens.

[0089] Furthermore, the intraocular intraocular lens contact lens 300 can be easily removed from the patient's eye 102, such as after implantation or at any suitable time before the tactile elements 304a-304c are bonded to the capsular wall (assuming fibrosis or refibrosis keeps the intraocular intraocular lens contact lens 300 in place). This particularly allows for the removal of one intraocular intraocular intraocular lens contact lens 300 and its replacement with a different intraocular intraocular intraocular intraocular lens contact lens 300 if a different optical magnification is required or desired.

[0090] The intraocular intraocular lens contact lens 300 can have any suitable size, shape, and dimension. For example, the intraocular intraocular lens contact lens 300 can be manufactured in a diameter range from about 4 mm to about 6 mm. Furthermore, the intraocular intraocular lens contact lens 300 can be fabricated with a basic curvature for variations in its optical lens 302. Of course, the intraocular intraocular lens contact lens 300 can also be custom-designed for a specific patient's eye 102, such as when one or more specific curvatures are required to provide the desired optical magnification in a specific patient's eye 102.

[0091] In some embodiments, the intraocular lens contact lens 300 and its various components may have the following design parameters: the diameter of the first lens portion 312 may be about 2.25 mm, the diameter of the second lens portion 314 may be about 4.5 mm, the diameter of the circle defined by the ridge 308 may be about 6.05 mm, and the diameter of the circle defined by the outer edges of the tactile elements 304a-304c may be about 7 mm. When viewed from above, the straight edges of each tactile element 304a-304c may taper gradually from an interval of about 0.97 mm to about 0.63 mm, wherein the straight edges define an angle of about 15°. The optical lens 302 may have a thickness of about 0.375 mm along its outer edge and may have a step of about 0.065 mm between the rear surface of the optical lens 302 and the rear surface of the tactile elements 304a-304c along its outer edge. Each of the ridges 308 may form an angle of approximately 10° relative to the central optical axis of the optical lens 302, and the rear surfaces of the tactile elements 304a-304c may extend from the optical lens 302 at an angle of approximately 103° relative to the central optical axis of the optical lens 302. The distance between the outer edges of the ridges 308 and each tactile element 304a-304c may be approximately 0.48 mm. Various corners and edges of the intraocular lens contact lens 300 may be rounded, and the radii of curvature of the anterior and posterior surfaces of the first and second lens portions 312-314 may vary based on the desired optical magnification(s) provided by the lens portions 312-314. However, it should be noted that these dimensions and other design parameters are for illustrative purposes only and may vary as needed or desired depending on the implementation of the intraocular lens contact lens 300.

[0092] The intraocular intraocular lens contact lens 300 can be non-invasively implanted into a patient's eye 102 and easily positioned on the intraocular lens 112. The implantation is non-invasive because the intraocular intraocular lens contact lens 300 is mounted on the anterior surface of the intraocular lens 112, which is typically easily accessible to the surgeon or other personnel during implantation. The implantation is also non-invasive because the intraocular intraocular intraocular lens contact lens 300 can be attached to the intraocular lens 112 without requiring attachment to anatomical structures within the patient's eye 102, such as the pupil. The non-invasive implantation and easy positioning of the intraocular intraocular lens contact lens 300 provide a safe and effective surgical procedure to correct AMD or other eye conditions.

[0093] If the tactile elements 304a-304c of the intraocular lens contact lens 300 include ridges 308, the ridges 308 can be used to center the intraocular lens contact lens 300 on the underlying intraocular lens 112, as described above. If the intraocular lens contact lens 300 includes multiple tactile elements 304a-304c with associated ridges 308, the ridges 308 can help to perfectly center the intraocular lens contact lens 300 on the underlying intraocular lens 112. This method allows the ridges 308 of the tactile elements 304a-304c of the intraocular lens contact lens to capture the underlying intraocular lens 112 at its edges and to perfectly align the optical center of the intraocular lens contact lens with the optical center of the intraocular lens 112. This alignment helps to reduce or avoid induced optical aberrations or induced prisms caused by optical center misalignment.

[0094] It should be noted that in the above example, the intraocular lens contact lens 300 may be designed such that only the tactile elements 304a-304c of the intraocular lens contact lens 300 extend below the anterior leaf of the capsule wall in the patient's eye 102. This allows the tactile elements 304a-304c to be captured and confined by the anterior leaf, while leaving the optical lens 302 of the intraocular lens contact lens 300 free and generally not obstructed by the surrounding tissues in the patient's eye 102.

[0095] It should also be noted that, in some embodiments, a surgical tool disclosed in U.S. Patent Application Publication No. 2019 / 0269555A1 (the entire contents of which are incorporated herein by reference) can be used to assist in the implantation of an intraocular intraocular lens contact lens 300. For example, this tool can be used to separate at least a portion of the anterior leaf of a patient's eye 102 from the implanted intraocular lens 112, allowing the tactile elements 304a-304c of the intraocular intraocular lens contact lens 300 to be inserted between the anterior leaf and the intraocular lens 112. As another example, this tool can be used to separate the anterior leaf of a patient's eye 102 from the implanted intraocular intraocular intraocular lens contact lens, thereby allowing the intraocular intraocular intraocular lens contact lens to be removed (and possibly replaced).

[0096] although Figures 3 to 9 The illustration shows an example of an intraocular intraocular lens contact lens 300 used in the Galileo vision system 100, but other examples may be included. Figures 3 to 9Various modifications can be made. For example, the intraocular intraocular lens contact lens 300 can include any suitable number of each component shown in the figures. As a specific example, although the optical lens 302 is shown as having two parts 312 and 314, the optical lens 302 can have more than two regions (such as two or more annular regions surrounding a central region). Furthermore, the forms of the tactile elements 304a-304c shown herein are merely examples, and any other suitable structure or other mechanism can be used to secure the intraocular intraocular lens contact lens 300 in place. In addition, many other features can be used at one or more locations of the intraocular intraocular lens contact lens 300. For example, one or more drug-eluting materials can be placed on the top, side, or bottom surface of the optical lens in the intraocular intraocular lens contact lens. Furthermore, the specific dimensions, diopter, optical power, and other values ​​described above are for illustrative purposes only and do not limit the invention to the specific values.

[0097] also, Figures 3 to 9 The intraocular intraocular lens contact lens 300 shown illustrates one example of an intraocular device type that can be designed or modified for use in the Galileo vision system 100. However, various other intraocular devices can be designed or modified for use in the Galileo vision system 100. For example, U.S. Patent Application Publication No. 2020 / 0121446A1 and U.S. Patent Application Publication No. 2019 / 0076237A1 (both incorporated herein by reference in their entirety) disclose a variety of intraocular intraocular lens contact lenses that can be modified to include an optical lens providing a central high negative power optical magnification, which would allow those intraocular intraocular lens contact lenses to be used in the Galileo vision system 100. The intraocular intraocular lens contact lenses disclosed in the above-incorporated documents, in particular, use pins, tactile rings, or other structures to secure the intraocular intraocular lens to the intraocular lens, and any of these structures can be used with the intraocular intraocular lens contact lens in the Galileo vision system.

[0098] Figure 10 and Figure 11 An example combination of an intraocular intraocular lens contact lens 300 and an artificial intraocular lens 112 that can be used in the Galileo vision system according to the present invention is illustrated. For ease of explanation, this combination can be described as being used for Figure 1 and Figure 2 The Galileo vision system 100. However, this combination can be used in any other suitable Galileo vision system, and the Galileo vision system can use any other suitable combination of intraocular intraocular contact lens and intraocular lens.

[0099] like Figure 10 and Figure 11As shown, the intraocular lens 112 includes an optical lens 1002 and a tactile element 1004 extending from the optical lens 1002. The optical lens 1002 receives light that has passed through the intraocular intraocular lens contact lens 302 and focuses the light onto the retina of the eye 102. The tactile element 1004 helps to hold the intraocular lens 112 within the capsule 110, such that the optical lens 1002 is in a desired position within the eye 102. It should be noted that the forms of the optical lens 1002 and the tactile element 1004 shown herein are merely examples, and other intraocular lenses may include different optical lenses or different tactile elements.

[0100] Figures 12 to 14 An example connection between an intraocular intraocular lens contact lens 300 and an artificial intraocular lens 112 for a Galilean vision system according to the present invention is illustrated. For ease of explanation, the connection can be described as being performed to aid in the formation of... Figure 1 and Figure 2 The Galileo vision system 100. However, this connection can involve any other suitable Galileo vision system, and the Galileo vision system can use any other suitable connection between the intraocular intraocular lens and the intraocular lens.

[0101] like Figure 12 As shown in the diagram, an intraocular lens contact lens 300 and an intraocular lens 112 are illustrated in a side view, with the intraocular lens contact lens 300 moving toward the intraocular lens 112. The outer portion 1202 of each tactile element 304a-304c is partially angled upwards here, which facilitates the attachment of the intraocular lens contact lens 300 to the intraocular lens 112, as described below. The intraocular lens contact lens 300 can be moved toward the intraocular lens 112 in any suitable manner, such as when a surgeon or other person grasps and manipulates the intraocular lens contact lens 300 using tools.

[0102] like Figure 13 As shown, the intraocular intraocular lens contact lens 300 is placed on the anterior surface of the intraocular lens 112. However, in Figure 13 In this context, it is assumed that the outer portion 1202 of the tactile elements 304a-304c is not positioned below the anterior leaf of the eye 102, which is why the outer portion 1202 of the tactile elements 304a-304c is still partially angled upwards. This allows the ridge 308 of the tactile elements 304a-304c to more easily surround and capture the outer edge of the optical lens 1002 of the intraocular lens 112.

[0103] like Figure 14 As shown, the intraocular intraocular lens contact lens 300 is now fixed to the anterior surface of the intraocular lens 112. Figure 14In this configuration, it is assumed that the outer portions 1202 of the haptic elements 304a-304c have been placed below the anterior leaflet in the eye 102. The anterior leaflet exerts a downward force on the outer portions 1202 of the haptic elements 304a-304c. Assuming that the haptic elements 304a-304c are flexible, this surface pressure causes the outer portions 1202 of the haptic elements 304a-304c to deflect and partially angle downward, which helps drive the ridge 308 (and optionally any lip or other structure on the ridge 308) into the outer edge of the optical lens 1002 of the intraocular lens 112. This helps to secure the intraocular intraocular lens contact lens 300 to the intraocular lens 112 and helps to align the optical axes of the intraocular intraocular lens contact lens 300 and the intraocular lens 112.

[0104] although Figure 10 and Figure 11 The illustration shows an example of a combination of an intraocular intraocular lens contact lens 300 and an artificial intraocular lens 112 that can be used in the Galileo vision system 100, and Figures 12 to 14 The illustration shows an example of the connection between the intraocular intraocular lens contact lens 300 and the artificial intraocular lens 112 for the Galileo vision system 100, but it is possible to modify the image. Figures 10 to 14 Various modifications can be made. For example, any other suitable mechanism (possibly involving only surface tension) can be used to hold the intraocular intraocular lens against or against the intraocular lens.

[0105] Figure 15 An example method 1500 for forming a Galilean visual system according to the present invention is illustrated. For ease of explanation, method 1500 is described as using an intraocular intraocular lens contact lens 300 and an external lens 116 as part of the formation of a Galilean visual system 100. However, method 1500 can use any other suitable intraocular intraocular lens contact lens and any other suitable external lens and can form any other suitable Galilean visual system.

[0106] like Figure 15As shown, in step 1502, an intraocular intraocular lens (IOPCL) is inserted into the patient's eye and secured in place in the patient's eye at step 1504. This may include, for example, a surgeon or other person selecting (such as from a kit) an IOPCL 300 that provides the desired amount of high negative power optical magnification. This may also include a surgeon or other person making a small incision in the patient's eye 102 and inserting the IOPCL 300 into the eye 102 through that incision. The IOPCL 300 may be rolled up, folded, or otherwise reduced in cross-sectional size to allow insertion through a smaller incision. This may further include one or more tactile elements 304a-304c of the IOPCL 300 sliding under the anterior leaf of the capsule wall in the patient's eye 102 or otherwise inserted.

[0107] At step 1506, an external optics device is selected for the intraocular intraocular lens contact lens, and at step 1508, the external optics device is obtained. This may involve, for example, a surgeon or other person selecting a suitable external lens 116 that provides a desired amount of high positive optical magnification. This may also involve a surgeon or other person forming the external lens 116, or a patient otherwise obtaining the external lens 116 with the desired amount of high positive optical magnification. At step 1510, the intraocular intraocular lens contact lens and the external optics device are used as a Galileo vision system. This may involve, for example, a patient wearing the external lens 116 (which acts as the objective of the Galileo vision system) while having an implanted intraocular intraocular lens contact lens 300 (which acts as the eyepiece of the Galileo vision system).

[0108] although Figure 15 An example of a method 1500 for forming Galileo's visual system 100 is illustrated, but it is possible to modify it further. Figure 15 Various changes were made. For example, although it was shown as a series of steps, Figure 15 The steps in the process can overlap, occur in parallel, occur in different orders, or occur any number of times.
