Abstract

Purpose: To analyze the efficacy, safety and stability in myopic and astigmatic small‐incision lenticule extraction (SMILE) with simultaneous prophylactic corneal crosslinking (CXL) in thin corneas.
Methods: A total of 48 eyes from 24 patients who underwent myopic and astigmatism SMILE with simultaneous prophylactic CXL were included in this retrospective study. All patients had a 12‐month follow‐up. A femtosecond laser was performed with LDV Z8 (Zeimer). CXL treatment was applied when the predicted stromal thickness was less than 300 μm. Results: The patients’ mean age was 20.58 ±3.12 years. The previous mean spherical equivalent was − 6.85 ± 1.80 (−9.75 to − 5.00) D. The postoperative mean spherical equivalent was − 0.50 ± 0.26 (−1.00 to + 0.25) D; 60% of the eyes had 20/20 or better; 81% of eyes had 20/25 or better; 60% were within ± 0.50 D; and 8.3% of the eyes changed 0.50 D or more between 3 and 12 months. Conclusion: Prophylactic CXL with simultaneous SMILE for myopia and astigmatism femtosecond laser surgery technique appears to be partially effective, safe, predictable, and stable after 12 months of follow‐up.
