Summary
Laser vision correction enhancement (LASIK retreatment) is effective for myopia. This study shows good visual acuity and stable results one year after enhancing LASIK surgery with the VISX Star excimer laser.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Myopic laser in situ keratomileusis (LASIK) is a common procedure for vision correction.
- Enhancements may be needed to address residual refractive error after primary LASIK.
Purpose of the Study:
- To evaluate the outcomes of LASIK enhancement for myopia using the VISX Star excimer laser.
- To assess the safety and efficacy of LASIK retreatment.
Main Methods:
- A prospective study involving 52 eyes of 40 patients undergoing LASIK enhancement.
- The existing LASIK flap was lifted, and retreatment was applied using the VISX Star excimer laser for residual refractive error.
- Follow-up included assessments at 1 month, 6 months, and 12 months post-enhancement.
Main Results:
- Mean spherical equivalent improved from -0.77 D to -0.13 D one year post-enhancement.
- Mean uncorrected visual acuity improved from 20/60 to 20/25, with all patients achieving 20/40 or better.
- Refraction remained stable over the 12-month follow-up, with no significant loss of best-corrected visual acuity and no epithelial ingrowth.
Conclusions:
- LASIK enhancement, initiated 6 weeks post-primary procedure, is effective for correcting residual myopia.
- The technique of lifting and repositioning the flap for retreatment is safe.
- Good visual outcomes and minimal complications were observed following LASIK enhancement.
