Özet
SIGNIFICANCE After epithelium-off crosslinking (CXL), epithelial closure time and post-operative pain are an important issue in terms of possible complications and patient comfort. We report a prospective randomized study about the use of autologous serum eye drops after CXL. PURPOSE This study aims to evaluate the effect of autologous serum eye drops on epithelial healing and post-operative pain after CXL. METHODS Sixty patients diagnosed as having progressive keratoconus and treated with accelerated CXL (9 mW/cm2 for 10 minutes) randomly received 20% autologous serum eye drops (autologous serum group, n = 30) or artificial tears (control group, n = 30). Patients were evaluated every day after the surgery, and the day of epithelial closure was recorded. All patients were asked to report the maximum pain level using the Wong-Baker FACES Pain Rating Scale at the end of each day until the epithelial closure was completed. The change in topographic parameters and haze were recorded at 6 months. RESULTS The mean epithelial closure time was significantly lower in the autologous serum group than in the control group (2.37 ± 0.49 and 2.67 ± 0.47 days, respectively; P =.02). There was a statistically significant difference between the pain scores in the first and second days of surgery between the two groups (first-day autologous serum autologous serum group: 2.80 ± 0.66 and control group: 3.50 ± 0.82, P =.01; second-day autologous serum group: 1.73 ± 0.69 and control group: 2.20 ± 0.76, P =.02). Pre-operative and post-operative topographic parameters and haze at 6 months were similar between the two groups (P >.05 for all). CONCLUSIONS Use of autologous serum eye drops after CXL accelerates epithelial healing and reduces post-operative pain. Shortening the duration of epithelial closure would be beneficial in reducing possible complications and increasing patient comfort.
