Clinical Result of LASIK using Meditec Mel 60 in Myopia

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(-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.
