PURPOSE This study was designed to identify possible differences between healthy subjects and patients with primary open-angle glaucoma (POAG) in keratometry, central corneal thickness, overall corneal thickness, mean thickness of a circular zone centered at the corneal apex of 1-mm radius (zone I), and mean thickness of several concentric rings also centered at the apex of 1-mm width (zones II...

Purpose: To investigate the interocular difference of axial length (AL), mean keratometry (K), corneal astigmatism and anterior chamber depth (ACD) according to AL without history ocular surgery.Methods: This study was performed on 16,411 patients (32,825 eyes) who were measured AL, K, ACD by IOL Master® from April 2007 September 2016, excluding with missing values extreme in AL. After, divided...

Background/aims—Post-keratoplasty astigmatism can be managed by selective suture removal in the steep axis. Corneal topography, keratometry, and refraction are used to determine the steep axis for suture removal. However, often there is a disagreement between the topographically determined steep axis and sutures to be removed and that determined by keratometry and refraction. The purpose of thi...

We have assessed the role of bandage contact lenses in the primary treatment of traumatic corneal abrasions. Patients treated with bandage lenses healed more quickly (0.05 greater than p greater than 0.02) and with less discomfort (0.05 greater than p greater than 0.02) than those treated traditionally, with the added advantage of maintaining vision during treatment. Resterilisation of contact ...

ABSTRACT Purpose: To evaluate the corneal and anterior chamber morphology in phakic eyes with noninfectious intraocular inflammation. Methods: This study included 59 active uveitis, 62 inactive 95 healthy eyes. Corneal endothelial cell density, hexagonal ratio, coefficient of variation (CV), thickness volume, maximum keratometry, volume depth (ACD) measurements were performed using a specular m...

OBJECTIVE Revision of methods for estimating corneal power (Kpost) and effective lens position (ELP) for cataract surgery after corneal refractive surgery. METHODS Review of medical literature. RESULTS To calculate the intraocular lens that achieves emetropia after corneal refractive surgery it is necessary to correct the Kpost and to estimate the effective lens position again correcting it...

purpose: to report the outcomes of graft refractive surgery (grs) together with clear-cornea phacoemulsification and intraocular lens (iol) implantation in post-penetrating keratoplasty (pkp) eyes. methods: fourteen eyes of 13 patients who had received pkp underwent simultaneous grs (relaxing incisions with or without counter-quadrant compression sutures) and clear-cornea phacoemulsification wi...

PURPOSE To compare 2 sequences of combined intrastromal corneal ring segment (ICRS) implantation and ultraviolet/riboflavin-mediated corneal collagen crosslinking (CXL) in progressive keratoconus. SETTING Dunya Eye Hospital, Istanbul, Turkey. METHODS In this prospective comparative randomized consecutive study, CXL was followed by ICRS implantation (Group 1) or ICRS implantation was followe...

PURPOSE To report the outcome of cataract surgery with implantation of the Z-flex 690TA hydrophilic acrylic toric intraocular lens (IOL).
 METHODS We enrolled consecutive patients who had 1.75 D or more of preexisting corneal astigmatism. Patients had cataract extraction surgery with implantation of a Z-flex 690TA toric IOL (Medicontur, Hungary). Refractive outcomes, keratometry, correction r...

PURPOSE To evaluate the validity of a keratometry (K)-independent method of estimating effective lens position (ELP) before phacoemulsification cataract surgery. SETTING Institute of Eye Surgery, Whitfield Clinic, Waterford, Ireland. DESIGN Evaluation of diagnostic test or technology. METHODS The anterior chamber diameter and corneal height in eyes scheduled for cataract surgery were meas...
