Purpose: To report a case of LASIK using Intralase® due to residual myopic astigmatism, 14 years after radial keratotomy. Methods: Thirty-nine years-old male patient who had undergone bilateral RK operation for myopic correction was admitted to Turkiye Hospital, for the correction of the residual refractive error in his left eye. The manifest refraction was -1.25(-3.00@175), UCVA was 20/50 and ...

PURPOSE To evaluate agreement in central corneal thickness (CCT), keratometry, and anterior and posterior elevation map measurements in normal corneas between a combined Placido-Scheimpflug system and a combined Placido-scanning-slit elevation topography system. SETTING Department of Cataract & Refractive Surgery, Rothschild Foundation, Paris, France. DESIGN Evaluation of diagnostic test or...

OBJECTIVE To investigate the effects of encircling scleral buckle (SB) on corneal biomechanical properties of the cornea and its morphological parameters. METHODS We prospectively examined twelve eyes diagnosed with vitreous haemorrhage undergoing pars plana vitrectomy (PPV), and fifteen eyes undergoing combined PPV and scleral buckle (PPV/SB) for repair of rhegmatogenous retinal detachment (...

PURPOSE Traditionally, orthokeratology has used diagnostic lenses to determine the best fit. The purpose of this study was to determine the efficacy of fitting empirically from corneal topography, without the use of diagnostic lenses. METHODS Twenty-nine subjects, 18 to 37 years old, with myopia of 1.00 to 4.00 diopters (D) and astigmatism of no more than 1.50 D, were entered into this 6-mont...

BACKGROUND To investigate the difference of ocular biometric and corneal topographic characteristics between the two eyes in high anisometropes with difference of 4 D or more in spherical component. METHODS Fifty-one young anisometropic men were collected. Detailed ocular examinations, including cycloplegic autorefraction, best-corrected visual acuity, intraocular pressure, A-scan, and Orbsca...

PURPOSE To determine the 1-year stability of LASIK in corneas with topographic suspect keratoconus confirmed as non-keratoconic by epithelial thickness mapping. METHODS This was a retrospective case/control comparative study. Eyes suspected of keratoconus using criteria based mainly on Atlas (Carl Zeiss Meditec AG) and Orbscan II (Bausch & Lomb) topography were scanned by Artemis very high-fr...
