About this study
Official title: Quantitative Refractive Crosslinking in Presbyopia-Aged Patients: An Open Label, Multi-center, Phase I Study of the TECLens Corneal Crosslinking System for Correction of Refractive Error in Patients of Presbyopia Age
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Quantitative refractive crosslinkingDevice
Non-invasive corneal crosslinking device delivering controlled UV light through a contact lens platform for refractive reshaping of the cornea.
| Study group | Role | What they receive |
|---|---|---|
| Treatment Group | Experimental | Epithelium-on Corneal Crosslinking Receives: Device: Quantitative refractive crosslinking |
What is being measured
The primary outcome is the main question the study is designed to answer.
Reduce refractive error
Achieve manifest refraction outcome at 3 months post treatment within 0.75D of the pre-planned targeted refraction, in patients aged 40 to 65 years old
Measured: 3-months post procedure
