Muhemmed Swadique* and Hassan Sanooj

ABSTRACT

Back Ground: Laser in situ keratomelusis (LASIK) is a widely used refractive surgery technique. Corneal wavefront guided LASIK treatment is a newly evolving method to correct preexisting high order aberrations and also to reduce induction of further aberrations. This study is to assess the efficacy and safety of Corneal wavefront guided LASIK treatment in myopic astigmatism. Methods: This is a prospective study of 30 eyes of 16 patients who underwent Corneal wavefront guided LASIK treatment. The pre operative and post operative one and three month data were collected and analyzed. Results: The post operative mean BSCVA at 1 month was 1.02±0.2 and at 3 month was 1.02±0.18. The change in BSCVA at 1 month was 0.09±0.22 and at 3 month was 0.10 ± 0.22(p <0.001). The change in RMS of 4th order HOA is 0.08±0.01D (p<0.001). and that of the 5th order HOA is 0.02 ±0.04 D (p<0.001). Conclusion: Corneal wavefront guided LASIK treatment is safe and effective in treating patients with myopic astigmatism.
