ABSTRACT
PURPOSE: To evaluate and report the visual, refractive, and aberrometry outcomes of laser in situ keratomileusis (LASIK) to correct low to moderate myopia using a commercial solid-state laser. SETTING: Oftalmar, Medimar International Hospital, Alicante, Spain. DESIGN: Prospective case series. METHODS: This study evaluated consecutive eyes with low to moderate myopia that had LASIK performed using a Pulzar Z1 solid-state laser. Visual, refractive, and aberrometry changes as well as potential complications were evaluated. RESULTS: The study enrolled 60 eyes (34 patients). The mean follow-up was 8.5 months (range 6 to 13 months). There was a significant improvement in logMAR uncorrected distance visual acuity (UDVA) postoperatively (P<.01). No significant change was detected in logMAR corrected distance visual acuity (CDVA) (P=.21). The postoperative logMAR UDVA was 0.1 (approximately 20/25) or better in 57 eyes (95.00%). The mean overall efficacy index was 0.99 and the mean safety index, 1.02. Postoperatively, 1 eye (1.67%) lost lines (1 line) of CDVA. The postoperative spherical equivalent was within ± 0.50 diopter in 58 eyes (96.67%). There was a small, but statistically significant increase in the primary coma root mean square (0.17 µm) and in the magnitude of primary spherical aberration (0.09 µm). No severe complications occurred. CONCLUSION: Laser in situ keratomileusis using the solid-state laser provided predictable correction of low to moderate myopia, minimizing the induction of higher-order aberrations and preserving CDVA.
