Purpose
Safety and efficacy customized-minimal PRK
Setting
20 patients (40 eyes) underwent customized PRK for myopia with custom-shape and diameter epithelial removal, Bromfenac 0.9mg/ml the first postoperative day. Visual acuity, CDVA, UDVA, refraction, post-operative pain measured on a subjective scale, epithelial healing and epithelial mapping profile were evaluated for 12 months.
Methods
20 patients (40 eyes) underwent customized PRK for myopia with custom-shape and diameter epithelial removal, Bromfenac 0.9mg/ml the first postoperative day. Visual acuity, CDVA, UDVA, refraction, post-operative pain measured on a subjective scale, epithelial healing and epithelial mapping profile were evaluated for 12 months.
Results
Pain scores were 0.27 ± 0.15 (0-4). Day 2 epi-defect was 1.52 ± 1.23 mm2. 8 eyes were not epithelialized by day 3, and none by day 4. 4 patient’s reported use of additional analgesia. All eyes were 20/25 immediately after the procedure and all 20/25 by day 4. At 3 months UDVA was 20/15,5, Residual refractive error: -0.15 Diopters. Residual manifest cylinder -0.18 Diopters; high order aberrations: 0,21um.
Conclusion
PRK, may minimize pain and visual debilitation, by accelerating re-epithelialization and early visual recovery. These data appear superior to LASIK and Smile for the immediate postop rehabilitation and restrictions, similar in discomfort experienced with both of these lamellar procedures, with a potentially superior intra-operative safety profile.
