Abstract


OBJECTIVE: To evaluate and compare the refractive status of myopic and hyperopic patients before and after one day, seven days and one month of LASIK (laser-assisted in-situ keratomileusis) surgery.

METHOD: 131 eyes of 66 patients of which 33 were myopic and 33 patients were hypermetropic, underwent femtosecond LASIK surgery. Follow-ups were made after one day, 7 days and one month of LASIK surgery and then a pre and post-LASIK comparison of best unaided visual acuity were performed using LogMAR visual acuity chart. The patients mean age was 24.1±4.1 years. The mean post-operative spherical equivalent (SE) for myopia was -0.50±0.7D. The mean post-operative spherical equivalent (SE) for hyperopes was -0.24±0.5D. Uncorrected visual acuity after 1 day, 7days and one month of LSIK surgery was to be evaluated.

RESULTS: Out of 66 patients 65.15% were females and 34.85% were male. 33 patients were myopic while the other 33 were hyperopic. After one month of LASIK  surgery using femtosecond laser for flap creation, the mean percent success of myopia was 98.6±3.1% and mean percent success of hyperopia was 97.4±4.9%. P-value was less than 0.001. After one day of LASIK, 80.3% of right eyes and 72.7% of left eyes show 100 percent success. After 7 days of LASIK, 84.4% of right eyes and 83.3% of left eyes shows 100 percent success. After one month of LASIK surgery, 84.4% of right eyes and 83.3% of left eyes shows 100 percent success.

CONCLUSION: LASIK surgery using femtosecond laser is a safe and predictable procedure for the correction of myopic and hyperopic refractive errors. LASIK is associated with faster recovery of vision and greater comfort in the early postoperative period.
