Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An 'on-eye' UV delivery system for corneal crosslinking can be used safely and effectively to help free presbyopic patients from the need for reading glasses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The clinical trial is evaluating the TECLens CXLens Crosslinking System, an investigational treatment using ultraviolet (UV) light (375 nm) with riboflavin (vitamin B2) to strengthen and reshape the cornea. By creating controlled biomechanical changes, this study aims to test whether the cornea can be reshaped to reduce refractive errors such as mild myopia or hyperopia in patients of presbyopic age.
