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)
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)
BACKGROUND To evaluate the average, minimum, and 6-sectoral macular ganglion cell-inner plexiform layer (GC-IPL) thickness measured by spectral domain optical coherence tomography (SD-OCT) in patients with Parkinson disease (PD), as well as average and 4-sectoral retinal nerve fiber layer (RNFL) thickness and to determine whether thickness parameters are(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 compare astigmatic keratotomy (AK) outcomes in high astigmatism after deep anterior lamellar keratoplasty (DALK) and after penetrating keratoplasty (PK) in keratoconus patients. DESIGN Prospective, comparative, interventional case series. METHODS This study comprised 20 eyes that underwent DALK and 24 eyes that underwent PK. After suture(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)
AIM To investigate the association of serum glucocorticoid kinase gene-1 (SGK-1) DNA variants with chronic central serous chorioretinopathy (CSC). METHODS We enrolled 32 eyes of 32 patients who were diagnosed with chronic CSC and composed 32 normal eyes as a control group. Peripheral blood was used for DNA extraction and polymerase chain reaction (PCR)(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 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 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)
