Abstract

Objective To evaluate the effect and safety of LASIK retreatment for correcting residual myopia and astigmatism. Methods The thirty-five eyes (from 22 patients) underwent secondary LASIK by model Keracor 116 excimer laser at 3-20 months after primary LASIK procedure. Following-up was 12 months. The statistical analysis of the data was made by the paired-samples t test. Results After retreatment, uncorrected visual acuity (UCVA) improved significant (P0.001), UCVA after secondary LASIK and best-corrected visual acuity (BCVA) after primary LASIK were with no significant difference (P0.05). Myopic refraction of all patients was within ±1.00D. Severe complications were not observed. Conclusions Secondary LASIK was an effective and safe method to treat regression after primary LASIK for high myopia.
