Purpose: To evaluate the long-term results of phakic refractive lens (PRL; Carl Zeiss Meditec) implantation in eyes with high myopia.
Methods: In this retrospective, noncomparative, interventional case series, 143 myopic eyes of 82 patients were treated for high myopia with the implantation of the silicone PRL in the posterior chamber.
Results: Mean follow-up was 3.
Purpose: To report a patient fifteen years after anterior chamber phakic intraocular lens (AC-PIOL) implantation in one and laser in situ keratomileusis (LASIK) in the fellow eye.
Methods: Case report.
Results: A 56-year-old male underwent AC-PIOL implantation in one eye and LASIK in the fellow eye fifteen years ago.
Purpose: To compare the early postoperative course and the 1-year clinical results of off-flap Epi-LASIK and Epi-LASIK for the treatment of low and moderate myopia.
Design: Pilot double-masked, randomized, comparative study.
Participants: Fifty-six patients (112 myopic eyes).
In order to evaluate the role of botulinum toxin induced ptosis as an occlusion method to treat unilateral deep strabismic amblyopia in two uncooperative children, we injected 0.2 ml of diluted botulinum toxin in the levator palpaebrae; low sedation was necessary in one of the two children. In both cases a marked ptosis was achieved, which lasted about four weeks and then gradually resolved completely.

Design: Retrospective, noncomparative, interventional case series.
Participants: Two hundred thirty-four eyes of 138 patients underwent epi-LASIK for the correction of low to moderate myopia.
Purpose: To compare the effect of Epi-LASIK or Laser In Situ Keratomileusis (LASIK) on corneal sensitivity and tear function.
Design: Prospective, non-randomized comparative clinical trial.
Methods: Seventy-nine eyes (Group A) underwent Epi-LASIK and 61 eyes underwent LASIK (Group B) for the treatment of myopia.
Purpose Of Review: The aim of this article is to provide an update on epipolis laser in-situ keratomileusis--an alternative surface photorefractive surgical technique for the correction of myopia.
Recent Findings: In-vivo studies on animal models provide evidence that the replacement of the epithelial sheet on an ablated cornea can control corneal wound healing. Preliminary clinical data confirm that epipolis laser in-situ keratomileusis can provide excellent long-term visual and refractive results.
Purpose: To report the histological findings of four eyes of three patients who underwent epi-LASIK treatment for the correction of low myopia.
Methods: The epithelial sheets were harvested either immediately after separation (one eye) or were accidentally dislocated and harvested from the operative eyes 24 hours after treatment (three eyes). All sheets underwent optical and transmission electron microscopy.
Purpose: To evaluate the clinical results of epi-LASIK, a new surface ablation surgical technique for the treatment of low myopia.
Setting: Vardinoyannion Eye Institute of Crete, University of Crete, Greece.
Methods: Forty-four eyes of 31 patients had epi-LASIK for the correction of low myopia.
Purpose: To evaluate the efficacy and safety of implantation of a new posterior chamber phakic refractive lens (PRL, Ciba Vision Surgical) in highly myopic eyes.
Setting: Department of Ophthalmology, Medical School, University of Crete, Vardinoyannion Eye Institute of Crete, Crete, Greece.
Methods: Thirty-four myopic eyes of 19 patients were treated for high myopia with implantation of a silicone PRL in the posterior chamber.
To compare the effect of mechanical and alcohol-assisted excision on the histological ultrastructure of epithelial disks from human corneas. Vardinoyiannion Eye Institute of Crete, University of Crete, Medical School, Crete, Greece. Ten eyes of 10 patients were deepithelialized by 1 of 2 two techniques.
View Article and Find Full Text PDFThe reports of an increasing incidence of iatrogenic ectasia, the evolution of wavefront aberrometry, and the suggestion that the laser in situ keratomileusis flap could lead to unpredictable biomechanical corneal changes have renewed interest in surface ablation and have set the stage for the introduction of alternative photorefractive treatment modalities. The theoretical advantage of surface procedures, such as laser epithelial keratomileusis that preserve the epithelial button, stems from the repositioning of the epithelial flap over the laser-ablated corneal surface. This epithelial sheet is thought to act as a natural contact lens that decreases postoperative pain and haze formation.

Methods: In this prospective nonrandomized clinical trial, 10 eyes of 7 patients with post-LASIK corneal ectasia (2 men and 5 women) aged 33 to 46 years (mean +/- SD, 40.67 +/- 5.
