PURPOSE: To describe the outcomes of retreatment for myopic regression following primary LASIK or PRK, and to explore factors associated with pre-retreatment refractive error.
METHODS: Retrospective cross-sectional study of eyes undergoing retreatment with LASIK, PRK, or ICL implantation after prior LASIK/PRK. Outcomes included UDVA, CDVA, MRSE, and safety and efficacy indices through 6-12 months. Associations between baseline factors and pre-retreatment MRSE were assessed.
RESULTS: 158 eyes were included (136 LASIK, 12 PRK, 10 ICL). Early postoperative outcomes improved significantly for LASIK (UDVA 0.37 to 0.04 logMAR; MRSE - 1.28 D to - 0.12 D) and ICL (UDVA 0.68 to 0.03 logMAR; MRSE - 2.72 D to 0.03 D). PRK also produced significant UDVA gains (0.63 to 0.06 logMAR). Efficacy and safety indices were near or above 1.0 across groups. A longer interval since primary surgery was significantly linked to more negative MRSE, consistent with greater regression. Mild correlation between pre-retreatment MRSE and age, initial MRSE, and tissue ablation were observed. Complications were low (7.9%).
CONCLUSIONS: Retreatment for myopic regression with LASIK, PRK, or ICL was safe and effective, with stable outcomes through 6-12 months. Regression was multifactorial and not predicted by baseline characteristics, though longer intervals between surgeries were significantly associated with greater myopic regression.
