Wavefront-Optimized Technology in Hyperopic Correction Stability Using Different Optical Zones

Purpose: To follow-up the visual and refractive outcomes of laser in situ keratomileusis (LASIK) to correct hyperopia using Wavelight Allegretto Wave since 2001. Setting: Eye Care Private One-Surgery Centre, Jeddah, Saudi Arabia. Methods: This retrospective study comprised 50 eyes of high hyperopia patients having spherical equivalence of +4.0 diopters (D) or more, treated with LASIK Wavelight Allegretto Wave. Outcomes are evaluated over follow-up visits. Patients underwent retreatment are excluded form this registry. Results: The mean patient age was 37.45±11.4 years. Fifty eyes were evaluated and followed-up over duration 56.76±8.62 weeks. No eye was retreated during the study. The mean manifest refraction spherical equivalent was +4.97±0.92 D preoperatively and +0.645±0.47 D postoper-atively. Fifty percent of eyes are within ±0.5 D while 94% were within ±1.0 D The preoperative best corrected visual acuity ranged 0.67-1 decimal scale (20/30-20/20 Snellen) and postoperative uncorrected visual acuity ranged 0.67-1 decimal scale (20/30-20/20 Snellen). Conclusion: This registry had shown overall success in correcting high hyperopia using Allegretto Wavefront-Optimized Technology. The optical zone of 7.0 D of Wave-front optimized technology is providing better efficacy and stability in hyperopic patients especially after the age 45 years.
