Abstract:
We evaluated 206 eyes of 105 patients who recieved LASIK with Meditec Mel 60 excimer laser and followed up for at least 6 months. We used 6 mm optical ablation zone to every passible patients and excuted photorefractive ablation after making corneal hinge flap using a 160 micrometerplate. The range of refractive error was from -1.75D to -13.50D and patients were divided into 3 group according to their manifest refraction error(spherical equivalent): Group I(<-6.00D, 120 eyes), Group II(-6.25D to -10.00D, 72 eyes), Group III(>-10.25D, 14 eyes). Mean preoperative spherical equivalent was -3.81D in group I, -7.63D in group II and -12.56D in group III. Mean spherical equivalent after LASIK at 1 Month was +0.05+/-0.60D in group I, 0.00+/-0.74D in group II, -0.12+/-0.99D in group III and at 3 Months, -0.11+/-0.58D, -0.19+/-0.75D, -0.59+/-0.90D and at 6 months -0.21+/-0.59D, -0.34+/-0.78D, -1.11+/-0.86D respectively. In group I, 90.6% of eyes were within 1D of attemped correction at 6 Months as were 80.6% in group II and 46.0% in group III. Mean UCVA at 6 month after LASIK was 1.02 in group I, 0.90 in group II, 0.75 in group III and uncorrected visual acuity of 0.8 or better was achieved in 91.6% of 118 eyes in group I, 88.5% of 67 eyes in group IIand 76.9% of 13 eyes in group III. LASIK done experienced surgeon appears to be safe, accurate, efficient to correct myopic refractive error.
