Official title
Open Label, Multi-center, Phase I Study of TECLens Corneal Crosslinking System for Correction of Refractive Error in Patients of Presbyopia Age.
Overview
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
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.
Interventions
- Device Quantitative refractive crosslinking
Non-invasive corneal cross-linking device delivering controlled UV light through a contact lens platform for biomechanical stabilization of the cornea.
Primary outcome measures
- Reduce refractive error [Time frame: 3-months post procedure]
Eligibility criteria
Inclusion criteria
- Adults aged 40-65 years
- Healthy cornea
- Refractive error between +4.0 D and -5.0 D
- Phakic or monofocal pseudophakic (≥6 months post IOL placement)
- Visual acuity correctable by ±0.25 D
Exclusion criteria
- Corneal dystrophy, scarring, or prior corneal crosslinking
- Astigmatism >1.0 D
- Active ocular infection, inflammation, or uncontrolled dry eye
- Advanced glaucoma or diabetic retinopathy
- History of delayed corneal healing
- Pregnancy, breastfeeding, or planning pregnancy during study period
- Certain medications (e.g., isotretinoin)
- Recent participation in other investigational drug/device studies (within 30 days)
- Patients with uncontrolled dry eye or surface disease
