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(More)
PURPOSE To investigate corneal tissue alterations after corneal collagen cross-linking in patients with post laser in situ keratosmileusis (LASIK) keratectasia and keratoconus. DESIGN Prospective comparative case series. METHODS Five patients (5 eyes) with iatrogenic keratectasia after LASIK and 5 patients (5 eyes) with progressive keratoconus were(More)
The 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(More)
OBJECTIVE To prospectively study the effects of the use of Intacs microthin prescription inserts (Addition Technology Inc, Fremont, Calif) for the postoperative management of corneal ectasia resulting from laser in situ keratomileusis (LASIK). METHODS In this prospective nonrandomized clinical trial, 10 eyes of 7 patients with post-LASIK corneal ectasia(More)
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. In 6 eyes, a customized instrument was used to(More)
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. Mean preoperative spherical equivalent was 3.71 diopters (D)(More)
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. Matching parameters between the groups were(More)
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(More)
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(More)
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(More)
