Summary

Corneal crosslinking (Crosslinking, CXL) is a treatment offered for the stabilization of early corneal ectatic disorders such as keratoconus. Although CXL is an excellent treatment option to stabilize early ectatic corneas, complications include corneal haze, sterile infiltrate, endothelial cell toxicity, treatment failure and stromal scarring. Corneal haze is a common finding in almost all CXL patients and may decrease visual quality. The effect of 0.02% mitomycin C (MMC) for 2 minutes on corneal haze and scarring in refractive surgery is well established in the literature with many clinical studies confirming its effectiveness. Although the pattern of corneal haze after CXL appears to be different from the haze pattern seen following refractive procedures, both processes are thought to be caused by an inflammatory response. The investigators postulate that MMC can reduce post-CXL haze and scars when using the optimal concentration and duration of exposure.

Conditions

Interventions

TypeNameDescription
DRUGApplication of 0.02% MMC over 60 seconds post corneal crosslinking.Topical application of 0.02% MMC on the surface of the cornea post CXL. The surface of the eye is washed thoroughly with Balanced Salt Solution (BSS) over 1 minute after MMC application.
DRUGCorneal crosslinking without the application of 0.02% MMCTopical application of placebo on the surface of the cornea post CXL. The surface of the eye is washed thoroughly with Balanced Salt Solution (BSS) over 1 minute after placebo application.
