AI Technical Summary

Technical Problem

Current two-dimensional intraocular lenses (IOLs) fail to adequately address capsular fibrosis, posterior capsule opacification, and refractive issues post-cataract surgery, leading to suboptimal visual acuity and increased risk of complications.

Method used

A three-dimensional intraocular lens (IOL) scaffold with fenestrations and pillars is designed to maintain capsule openness, allowing aqueous humor circulation and prevent fibrosis, while enabling attachment of secondary optics for precise refractive and astigmatic corrections.

Benefits of technology

The 3-D IOL scaffold maintains visual acuity by preventing capsule collapse, minimizing fibrosis and opacification, and allowing flexible lens placement for optimal refractive outcomes, reducing the need for secondary surgeries.

Abstract

Devices and methods for replacing a human lens after cataract surgery. The device is an insert for the eye capsule and is formed of two or more rings that are connected to one another. A primary lens is affixed to the insert. A secondary add-in lens can be added to the insert in a subsequent surgery to correct, or further optimise, the optical results obtained with the initial surgery.
