PURPOSE To report two cases of femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty (DLEK) for patients with corneal endothelial decompensation by Fuchs dystrophy and glaucoma METHODS Femtosecond laser (IntraLase; IntraLase Corp., Irvine, CA) with 15 kHz of repetition rate, was used for a 9.5 mm diameter by 400 micrometer thickness donor corneal lamellar dissection...

PURPOSE To evaluate the correlation between refractive, corneal, and residual astigmatism and higher order aberrations (HOA) in refractive surgery candidates. METHODS Three hundred and seventy-five eyes of 188 patients aged 28.2 ± 6.24 years with a predominance of females (62.7%) were enrolled in this study. Refraction, topography (Orbscan IIz, Bausch & Lomb, Rochester, NY, USA), and aberrome...

Purpose: Comparing the optical coherence tomography (OCT) pachymetry patterns in keratoconus suspect and normal people Methods: Thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. Their pachymetry pattern was obtained through OCT Visante in the minimum thickness spot, upper and lower corneal difference (I-S), lower temporal, and upper nasal thick...

to evaluate long term safety and efficacy of the photo refractive keratectomy (prk) in myopic eyes with thin cornea, this study has been designed. in this retrospective case series study, we included 74 eyes of 38 myopic patients with preoperative central corneal thickness (cct) less than 550 micrometer who underwent for prk surgery prior to 2010 and had 4 years of mean follow up postoperativel...

Background: The possible impact of corneal thickness, curvature, and size on the measurement of endothelial cell density (ECD) has largely been ignored in the normal eye. The aim of this study was to investigate the possible impact of the main corneal parameters on the analysis of ECD values at the central, superior, and temporal parts of the corneal surface. Methods: All 75 participants (52 fe...
