Purpose

To investigate safety, efficacy and stability of dried amnion used in APCXL 

Setting

The Laservision Clinical and Research Institute, Athens, Greece

Methods

This study included 50 eyes that have undergone APCXL which were randomly divided in two groups; in group-A an adjunct amnion disc was used,  under the bandage contact lens, while in group-B contact lens alone. Besides the subjective pain score, visual acuity, corneal keratometry, astigmatism, epithelial distribution and minimum corneal thickness were evaluated at the first postoperative day, the day of complete re-epithelization for each eye, 1, 3 and 6 months postoperatively.

Results

Mean Values: Pain score group a 0.5 (1-4) while group B 1 (P<0.02), Epithelization; day 5 vs. day 7 respectively. At 6 months there was statistically less anterior stromal scarring group A. The tomographic and visual function data were comparable between the 2 groups.

Conclusions

Thin amnion used as an adjunct bandage in AP CXL may accelerate re-epithelization, improve first day pain profile and also improve epithelial remodeling within the first postoperative month.
