Summary

The purpose of this study is to determine the effectiveness of collagen cross-linking in the cornea in halting the progression and possibly partially reversing the effects of keratoconus. Keratoconus is a progressive weakening in the cornea that causes irregular astigmatism and thinning of the cornea. The overall effect is reduction of vision, and in more advanced cases, scarring of the cornea that may lead to the need for corneal transplantation. Cross-linking has been shown increase the rigidity of the cornea. The patients would be treated once and then followed over 24 months. .

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Cross-linking treatmentExperimental Treatment1 Intervention
Topical anesthesia (lidocaine jelly 2%) will be used. The central 9 mm of corneal epithelium will be removed cautiously with an Amoils brush. Riboflavin 0.1% solution will be applied (10 mg riboflavin-5-phosphate in 10 ml dextran T-500 20% solution, supplied in a sterile, single dose container) to the cornea every 2-3 minutes for 15 minutes and then every 5 minutes thereafter. The UV source will be from the CBM VEGA X-linker (CSO, Florence, Italy). A wavelength of 370 nm will be used to direct 5.4 J/cm2 to the area of cornea debrided for 30 minutes. The distance from the UV source to the cornea will be 1.5 to 5.4 cm.
Group II: Sham treatment groupPlacebo Group1 Intervention
Topical anesthesia (lidocaine jelly 2%) will be used. Differing from the treatment group, no epithelium will be debrided, but instead, this step will be skipped and a 2% methylcellulose solution combined with 1% fluorescein dye will be applied to the cornea every 5 minutes for 30 minutes. The patient will be placed under the UV device, but instead of the UV light, the LED aiming beam will be applied for 30 minutes.
