Wavefront-Optimized LASIK in High Myopic Patients-Retrospective Analyses,ADNAN ELMARZOUKI
Abstract
Purpose: To follow-up the visual and refractive outcomes of laser in situ keratomileusis (LASIK) to correct high myopia using Wavelight Allegretto Wave since 2001.
Setting: Eye Care Private Center, Jeddah, Saudi Arabia.
Methods: This retrospective study comprised 112 eyes of 65 high myopic patients having spherical refraction –8 diopters (D) or more, treated with LASIK Wavelight Allegretto Wave. Eyes were analyzed preoperatively and 1,3 and 12 months postoperatively. Analyses were done on retrieved data from patient files.
Results: The mean patient age was 29.75±7.31 yeas. Gender 42 Female: 23 Male. Seventy two eyes were evaluated at 3 months, 85 eyes at 6 months and 81 eyes at 12 months.
All eyes have not been retreated during the study. The mean manifest refraction spherical equivalent MRSE was –8.67±2.54 D preoperatively and –0.54± 0.64 D for 3 months, –0.64±0.73 D for 6 months, and –0.7±0.82 for 12 months postoperatively.
Eyes were distributed as 16 eyes, 35 eyes and 61 eyes to optical zones of 5.5mm, 6mm and 6.5mm respectively.
Postoperatively 70 (62.5%) and 89 (79.46%) eyes were within ±0.50D and ±1.00D respectively of the intended cor-rection. After 12 months follow-up 56 (50%) and 80 (71.43%) eyes remained within ±1.00D and ±0.50D respectively. The 6.5mm had achieved 44 (72.13%) and 57 (93.44%) eyes within ±1.00D and ±0.50D respectively. Its results sustained to achieve 38 (62.29%) and 51 (83.61%) eyes within ±1.00D and ±0.50D respectively after the 12 months. The 6.5mm was the highest efficacy and sustainability.
No records of postoperative ectasia or adverse events had been encountered.
Conclusion: Wavefront-Optimized technology might provide sustained efficacy in high myopic patients. The 6.5mm OZ had shown less regression and higher efficacy.
