Purpose: To evaluate Laser Epithelial Keratomileusis (LASEK) for the correction of myopia and myopic astigmatism. Methods: 219 consecutive eyes with myopia and myopic astigmatism (mean spherical equivalent -4.90D, range -1.25 to -12.50D) underwent LASEK using the Summit Technology Apex Plus Laser. The epithelial flap was created using 15% alcohol applied for 20 seconds using the technique described by Camellin. A satisfactory intact epithelial flap was achieved in 98% of eyes. Results: Most patients experienced ocular discomfort only for the first 24 hours. Epithelial closure was achieved in all eyes by 3 days. At one week 93% could be corrected to 20/40 or better. Mean follow up was 7.6 months (range 3-12 months). At the last post-operative visit 79% were within +/- 0.50D and 93% were within +/- 1.00D of emmetropia. For corrections <-3.00D, 92% were within +/-0.50D and 100% were within +/-1.00D of emmetropia. Similarly, for corrections between -3.00 to -6.00D, 82% were within +/-0.50D and 98% were within +/-1.00D. For -6.00 to 12.50D, 71% were within +/-0.50D and 87% were within +/-1.00D. Vector analysis demonstrated an average of 93% achieved cylindrical correction. In 85% no corneal haze was detectable at the last post-operative visit. Best spectacle corrected acuity was increased or unchanged in 184 eyes (84%). 2 eyes (1%) lost 2 lines of BSCVA. Conclusions: LASEK appears to offer excellent refractive correction, with limited post-operative discomfort, fairly rapid visual recovery with little corneal haze and few complications.
