Summary
Wavefront-guided LASIK accurately corrects low to moderate myopia. Higher myopia levels may experience over- or undercorrections, with visual acuity stabilizing quickly post-procedure.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Wavefront-guided LASIK offers customized corneal treatments.
- Utilizes computer ablation profiles to correct refractive errors and aberrations.
- Treatments can address spherical and cylindrical refractive errors up to the fifth order.
Purpose of the Study:
- Evaluate the predictability, efficacy, stability, and safety of wavefront-guided LASIK.
- Assess outcomes for patients undergoing refractive correction.
- Analyze refractive results and visual acuity changes post-procedure.
Main Methods:
- Performed wavefront-guided LASIK on 62 patients using the Keracor 217 Z.
- Treated patients with an average spherical equivalent of -6.11 +/- 2.29 D.
- Collected and evaluated data for 3 months postoperatively.
Main Results:
- Good predictability observed for myopia correction between -1 D and -6 D.
- Over- and undercorrections of +/- 2 D occurred in 10% of procedures for myopia exceeding -7 D.
- 3 months postoperatively, 53% achieved uncorrected visual acuity (UCVA) of 0.8 or better, and 75% achieved best-corrected visual acuity (BCVA) of 0.8 or better.
Conclusions:
- Wavefront technology accurately corrects low to moderate myopia.
- Higher myopia degrees are associated with under- and overcorrections.
- Refractive stability is achieved rapidly, though visual acuity may change up to 6 months postoperatively.
