Purpose: We report our experience with the use of the matrix regenerating agent (RGTA) Cacicol® after reverse transepithelial all-surface laser ablation (ASLA)-SCHWIND to assess the safety, efficacy, pain, and epithelial healing.
Methods: Forty eyes of 20 myopic patients were prospectively recruited to a randomized fellow eye study. Patients underwent transepithelial ASLA in both eyes, with one of the eyes randomly assigned to the use of the RGTA Cacicol. Postoperative pain and vision were subjectively assessed with the use of a questionnaire on the operative day, at 24 hours, 48 hours and 72 hours. Epithelial defect area size was measured at 24 hours, 48 hours, and 72 hours. Uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were assessed at 1 month.
Results: Mean UDVA at 1 month was LogMAR 0.028. The epithelial defect area was 10.91 mm2 and 13.28 mm2 at 24 hours and 1.39 mm2 and 1.24 mm2 at 48 hours for treated and nontreated eyes, respectively. Overall, 50% and 65% of treated and nontreated eyes healed by 48 hours. There was no statistically significant difference in the subjective vision between the groups, although vision of patients in the RGTA group was reported to be better. Pain scores were better at 24 hours and 48 hours in the RGTA group but with no statistically significant difference.
Conclusion: The use of RGTA Cacicol shows faster epithelial recovery after transepithelial ASLA for myopia. Subjectively reported scores of pain and subjective vision were better in the RGTA group, although the difference was not statistically significant. There seems to be a consensual acceleration of epithelial healing even in eyes that did not receive treatment. There were no adverse events and no incidents of inflammation, delayed healing, or haze.
