PURPOSE To compare the outcomes of implantation of 2 models of intrastromal corneal ring segments (ICRS) to manage keratoconus. SETTING Kartal Training and Research Hospital, Istanbul, Turkey. METHODS This study evaluated eyes with keratoconus that had implantation of Keraring ICRS (Group A) or Intacs ICRS (Group B). The corneal tunnels were created(More)
PURPOSE To compare the outcomes of mechanical and femtosecond laser-assisted tunnel creation for intrastromal corneal ring segment (ICRS) implantation in eyes with keratoconus. SETTING Kartal Training and Research Hospital, Istanbul, Turkey. METHODS In this prospective study, consecutive eyes with keratoconus were randomly assigned to have ICRS tunnel(More)
BACKGROUND To evaluate the 3-year clinical outcomes after toric implantable collamer lens (ICL) implantation for the management of moderate to high myopic astigmatism. METHODS Thirty-four eyes of 20 patients who underwent toric ICL implantation were reviewed. All eyes completed 3-year follow-up. Uncorrected (UDVA) and corrected (CDVA) distance LogMAR(More)
PURPOSE To determine the visual and refractive outcomes of 210-degree arc length intrastromal corneal ring segment (ICRS) implantation in eyes with pellucid marginal corneal degeneration (PMCD). DESIGN Retrospective, consecutive case series. METHODS Sixteen consecutive eyes of 10 patients who underwent a single 210-degree ICRS implantation by(More)
PURPOSE To evaluate the effectiveness and safety of adjunctive mitomycin C (MMC) in Ahmed glaucoma valve (AGV) implantation for refractory glaucoma. METHODS Twenty-two eyes of 22 patients who underwent AGV implantation with adjunctive MMC (0.5 mg/ml) for 3 minutes (Group A) were compared to a control group of 26 eyes of 26 patients (Group B) who received(More)
PURPOSE To compare the status of corneal endothelium and central corneal thickness within the first four postoperative years after deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PK) in patients with keratoconus. MATERIALS AND METHODS Thirty-nine eyes (Group A) which had PK and 44 eyes (Group B) which had DALK for the treatment of(More)
PURPOSE To evaluate the safety and efficacy of intrastromal corneal ring segment implantation using both mechanical and femtosecond-assisted tunnel creation for the treatment of patients with keratoconus. METHODS A retrospective noncomparative interventional study including 96 eyes of 75 patients with keratoconus. All patients had contact lens intolerance(More)
PURPOSE To evaluate and compare visual and optical performance outcomes by means of analysis of the contrast sensitivity function (CSF) and ocular higher order aberrations (HOA) in patients with keratoconus who had deep anterior lamellar keratoplasty (DALK) or penetrating keratoplasty (PK). METHODS In this prospective, randomised case series, 174 eyes of(More)
PURPOSE The purpose of this study was to evaluate the results of fluorescein angiography-guided photodynamic therapy with half-dose verteporfin in the treatment of chronic central serous chorioretinopathy with focal leakage areas. METHODS Eight cases with a history of central serous chorioretinopathy of ≥6 months were included. All eyes had one or more(More)
PURPOSE To compare the results of penetrating keratoplasty (PK) in a series of congenital hereditary endothelial dystrophy (CHED) patients operated at amblyogenic years and at later ages. METHODS Records of 65 eyes of 35 CHED patients who underwent PK were reviewed retrospectively. Visual results and graft clarity rates were compared between patients(More)
