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/cm 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.
