title: Results of laser in situ keratomileusis performed using solid-state laser technology.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Oftalmar, Medimar International Hospital, Alicante, Spain.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
