PURPOSE To evaluate the visual and refractive results of laser in situ keratomileusis (LASIK) retreatment on eyes with residual myopia with or without astigmatism. METHODS LASIK retreatment was performed on 35 eyes of 23 patients for correction of residual myopia, with or without astigmatism, with a mean manifest spherical equivalent refraction of -2.17+/-0.82 D (range, -1.00 to -3.87 D) and ...

To the Editor: We were interested to read the recent study by Huang and co-authors (Huang D, Sur S, Seffo F, Mesiler DM, Krueger RR. Surgically-induced astigmatism after laser in situ keratomileusis for spherical myopia. J Refract Surg 2000;16:515-518) regarding the possible effect of the LASIK flap on surgically-induced astigmatism. In that study, the authors found that a superior hinge produc...

The broad acceptance of "spot scanning" or "flying spot" excimer lasers in the last decade has enabled the domination of corneal ablative laser surgery over other refractive surgical procedures for the correction of hyperopia, hyperopic and mixed astigmatism. This review outlines the most important reasons why the ablative laser correction of hyperopia, hyperopic and mixed astigmatism for many ...

The laser in situ keratomileusis (LASIK) is the most widely used refractory surgical method world with excellent results, but this not without risks. Post-LASIK ectasia a serious complication and characterized by progressive increase curvature thinning of cornea, resulting irregular astigmatism decreasing visual acuity. Its incidence current literature approximately 0.033%. main treatment for i...

purpose: to assess the efficacy and safety of laser in situ keratomileusis (lasik) for correction of residual myopia and astigmatism after penetrating keratoplasty (pk). methods: in this prospective interventional case series, lasik was performed on 14 eyes of 13 patients unable to wear glasses or contact lenses after pk. the interval between lasik and pk was at least one year. all patients had...

PURPOSE To evaluate the results of laser in situ keratomileusis (LASIK) performed to correct hyperopia, and hyperopic and mixed astigmatism using wider ablation diameters (optical zone diameter and overall ablation diameter) than those commonly used with the same and other lasers. METHODS After flap creation using an Alcon SKBM microkeratome set for a 10-mm flap diameter, 53 eyes (33 patients...

purpose: to evaluate the results of laser in situ keratomileusis (lasik) retreatment in  patients with postoperative regression. methods: in a retrospective interventional case series, 153 eyes of 113 patients who had undergone lasik retreatment for postoperative regression were evaluated. both initial lasik and retreatment were performed with a nidek: ec 5000 excimer laser, and flap was made w...

purpose : to compare the visual and refractive outcomes of laser in situ keratomileusis (lasik) versus laser assisted subepithelial keratectomy (lasek) in the treatment of low to moderate myopia and astigmatism methods : a retrospective comparative case series study comprised 2,474 eyes of patients with manifest refraction spherical component lower than -5.00 diopters (d) and cylinder component...

Purpose: To compare safety, efficacy, stability, and predictability of implantable collamer lens (ICL) with femtosecond-laser in situ keratomileusis (FS-LASIK) or small incision lenticule extraction (SMILE) for the correction moderate-to-high myopia/myopic astigmatism.
 Study design: We retrospectively collected data from patients astigmatism (spherical equivalent [SE] ≥ −3.00 diopters [D]...

AIMS To report the results of a series of patients who were treated with LASIK to correct post penetrating keratoplasty ametropia. METHODS 26 eyes of 24 patients underwent LASIK to correct astigmatism and myopia after corneal transplantation; 14 eyes also received arcuate cuts in the stromal bed at the time of surgery. The mean preoperative spherical equivalent was -5.20D and the mean preoper...
