چکیده
Purpose To describe a new technique to deliver riboflavin into the corneal stroma during Corneal Cross-Linking (CXL) without removal of epithelium. Methods Keratoconus patients underwent CXL for progressive keratoconus. Riboflavin was delivered by manually creating an epithelial pocket (CXL Epi-Pocket). Verbal rating scale recorded postoperatively. Best-corrected visual acuity, keratometric indices, thickness and densitometry were at baseline 12-month follow-up. Results Eighteen eyes 18 included in study. At follow-up, best-corrected K1, K2 values stable. Maximum keratometry (Kmax) reduced from 55.31 ± 6.21 (SD) 52.34d 4.12d (P value = 0.032). thinnest point went 441 21.18 425.4 19.02 um 0.041). The verbal 1, 2 3 days postoperatively 1.76 0.19 (SD), 1.02 0.51 0.28 0.14 (SD). Conclusions Epi-Pocket is able halt progression keratoconus

Effect of corneal epithelium on ultraviolet-A and riboflavin absorption.
PURPOSE To determine if the corneal epithelium prevents the collagen cross-linking effect. Using immunofluorescence microscopy after CXL, we indirectly analyzed the role of the epithelium as ultraviolet-A (UVA) shield as well as a barrier to riboflavin penetration. METHODS Fifteen freshly enucleated porcine eyes were divided into 3 groups. The corneal epithelium was kept intact in all groups....
متن کاملTitanium Snoreplasty- A New Surgical Technique
Introduction: Based on the previous data, among the general population aged between 30 and 60 years, snoring is observed in 44% and 28% of males and females, respectively. Therefore, it is important to treat snoring to reduce the disruption of the bed partner's sleep and the patients’ own problems. This study aimed to present a minimally invasive procedure which is easy to perform with le...
متن کاملA new surgical technique to treat corneal perforations using amniotic membrane and surgical adhesive
The objectives of this study were to compare surgical techniques and the effects of using n-butyl 2cyanoacrylate and bovine amniotic membrane to repair perforated lesions in corneas. Penetrating keratoplasty was performed in sixty New Zealand White rabbits under general anesthesia. Group 1 (G1) was treated with n-butyl 2-cyanoacrylate, group 2 (G2) received a fragment of amniotic membrane throu...
متن کاملRole of Corneal Epithelium in Riboflavin/Ultraviolet-A Mediated Corneal Cross-linking Treatment in Rabbit Eyes
PURPOSE To evaluate the role of corneal epithelium in riboflavin/ultraviolet-A (UVA) mediated corneal collagen cross-linking treatment. METHODS Fifty New Zealand rabbits were divided into 5 groups: UVA treatment with or without corneal epithelium, UVA+riboflavin treatment with or without corneal epithelium, and control without any treatment. All rabbits were sacrificed after irradiation and s...
