UV Light-emitting Contact Lens Device for Corneal Collagen Crosslinking Stabilizes Corneas with Keratoconus
An ultraviolet (UV) light-emitting contact lens device for corneal collagen crosslinking stabilizes and flattens corneas with keratoconus, according to a poster presented at the American Society of Cataract and Refractive Surgery (ASCRS) Virtual Annual Meeting.
In this prospective, non-masked, non-randomized, clinical trial, 9 patients (9 eyes) with advanced keratoconus underwent CXL performed using a scleral contact lens reservoir containing BAK preserved riboflavin 0.25% for 30 minutes followed by an exchange to the UV light-emitting contact lens device.
The following results were found:
- Uncorrected visual acuity was improved in 83.3% of eyes
- Best-corrected visual acuity was improved or remained stable in half of the eyes treated
- K1 and K2 values were stable or improved in 66.7% of eyes
- Kmax values remained stable or improved in 83.3% of eyes.
No complications related to the use of the device were observed.
