PURPOSE The aim of this study was to evaluate the accuracy of intraocular pressure (IOP) values from the new non-contact tonometer (NCT) Reichert R7 by comparing results with those from Goldmann applanation tonometry (GAT) and the Reichert Ocular Response Analyzer (ORA). Other ocular dimensions were assessed to evaluate their potential influence on the IOP values obtained. METHODS Ninety two ...

AIM To compare 1-year follow-up results of photorefractive keratectomy (PRK) with mitomycin C (MMC) and laser in situ keratomileusis (LASIK) for custom correction of myopia. METHODS Eighty-eight eyes of 44 patients with moderate myopia were randomised to PRK with 0.002% MMC for 1 min in one eye and LASIK in the fellow eye. The 1-year follow-up was evaluated. RESULTS There were no difference...

Purpose To assess the predictive accuracy of simulation-based LASIK outcomes. Methods Preoperative and 3-month post-LASIK tomographic data from 20 eyes of 12 patients who underwent wavefront-optimized LASIK for myopia were obtained retrospectively. Patient-specific finite element models were created and case-specific treatment settings were simulated. Simulated keratometry (SimK) values and t...

PURPOSE To determine the agreement between intraocular pressure (IOP) measurements using an automated non-contact tonometer (NCT), Goldmann applanation tonometer (GAT), and the ocular response analyzer (ORA) in subjects with primary congenital glaucoma (PCG). METHODS Twenty-nine eyes of 17 PCG patients underwent IOP measurements using NCT, GAT and ORA. Variables obtained by the ORA were corne...

Corneal Visualization Scheimpflug Technology (CST) and Ocular Response Analyzer (ORA) measurements were carried out in 105 eyes of 69 patients with primary open-angle glaucoma. All patients had axial length (AL), central corneal thickness (CCT), intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) and eight visual fields (VF)s with the Humphrey Field Analyzer. VF progression was...

Background & Aims: This study was carried out to determine the leading indications for corneal transplantation in Kerman province. Methods: Medical records of 186 patients underwent corneal transplantation during 3 years (2004-2006) in Shafa Medical Center were evaluated retrospectively. The initial diagnosis and causes of corneal grafting were recorded. Infectious keratitis (Bacterial, Fungal,...

To the Editor: Bak-Nielsen et al. recently reported on the dynamic assessment of keratoconus and the effects of corneal cross-linking (CXL).1 The authors described the corneal deformation during rapidly applied force via an air jet using ultra high-speed Scheimpflug technology (Corvis ST; Oculus Optikgeräte GmbH, Wetzlar, Germany).1 Patients with both untreated and CXL-treated keratoconus were ...
