Intraocular pseudophakic contact lens with mechanism for securing by anterior leaflet of capsular wall and related system and method

Abstract

An apparatus includes an intraocular pseudophakic contact lens (100, 400, 600, 900, 1100, 1300, 1400, 1600, 1900, 2216). The intraocular pseudophakic contact lens includes an optical lens (102, 402, 602, 902, 1102, 1302, 1402, 1602, 1902) configured to at least partially correct a residual refractive error in an eye (2200). The residual refractive error includes a refractive error that exists in the eye after implantation of an artificial intraocular lens (2210) in the eye. The intraocular pseudophakic contact lens also includes one or more haptics (104a-104b, 404a-404b, 604a-604b, 904a-904b,1104a-1104b, 1304a-1304c, 1404a-1404b, 1604a-1604b, 1904a-1904b) configured to be inserted under an anterior leaflet (2218) of a capsular wall in the eye in order to capture and confine the one or more haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against the artificial intraocular lens.

Description

technical field [0001] The present disclosure generally relates to implantable optical devices. More specifically, the present disclosure relates to a pseudophakic contact lens having a mechanism for fixation through the anterior leaflet of the capsule wall and a related system and method. Background technique [0002] In a normal human eye, light enters through the cornea and passes through the pupil, and the natural lens focuses the light onto the retina of the eye. However, due to cataracts or other problems, it may be necessary to replace the eye's natural lens with an intraocular lens (IOL). The term "pseudophakic" is used to describe an eye in which the natural lens has been replaced with an artificial lens. [0003] Before placing an intraocular lens in a patient's eye, a physician or other person typically selects an intraocular lens that is designed to provide the desired refractive correction for the patient's eye. For example, an intraocular lens may have optic...

AI Technical Summary

Problems solved by technology

For example, one IOL in a patient's eye can be replaced with a different IOL, but this usually carries a high risk of surgical complications

Ablation procedures (such as LASIK) on the cornea of ​​the patient's eye can be performed to correct the residual refractive error, but this can have a high level of unwanted side effects, especially in older patients

An additional IOL (often called a "piggyback" IOL) can be inserted in front of the existing IOL, but this is usually an invasive procedure that is associated with less predictable final refractive outcomes

Alternatively, an intracorneal lens (ICL) can be inserted into the cornea of ​​the patient's eye, but this is often more invasive and highly repulsive

In general, the above procedures are often unpredictable and carry a high degree of surgical risk

Furthermore, the devices used in the above procedures are difficult to remove and "reverse" any residual refractive error, resulting in a higher risk of induced visual aberrations for the patient
