Purpose
To investigate safety, efficacy and stability of dried amnion used after myopic PRK
Setting
The Laservision Clinical and Research Institute, Athens, Greece
Methods
This contralateral eye, consecutive case series study included 50 eyes of 25 patients who have undergone bilateral myopic PRK with mechanical epithelial removal , in which one eye (group-A) was treated with PRK, and adjunct amnion placed under the bandage contact lens, while the other eye (group-B) with PRK and 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. The tomographic and visual function data were comparable between the 2 groups.
Conclusions
Thin amnion used as an adjunct bandage in PRK may accelerate re-epithelization, improve first day pain profile and also improve epithelial remodeling within the first postoperative month.
