Aim: To investigate and compare the effects of pterygium surgery on mean anterior surface Simulated Keratometry (SimK) Holladay Equivalent Readings-65 (EKR65) detail report.
 Methods: Patients who underwent between August 2022 January 2023 were examined. All surgeries performed under local anesthesia with conjunctival autograft method. Pentacam topography was after detailed ophthalmologica...

Background and aims: Keratoconus is characterized by corneal ectasia and irregular astigmatism, which can lead to diminished vision and corneal scarring. Keratoconus is a condition that causes corneal ectasia and reduced vision in young adults. A proportion of these patients have progressive disease requiring corneal transplantation. Methods: The databases searched included OVID MEDLINE, MEDLIN...

AIMS To evaluate intra- and interobserver variability in measurements on normal and astigmatic corneas with keratometry and computerized videokeratography. METHODS Keratometric readings with the 10 SL/O Zeiss keratometer and topographic maps with the TMS-1 were obtained by two independent examiners on 32 normal and 33 postkeratoplasty corneas. Inter- and intraobserver coefficients of variabil...

Background. To estimate repeatability and comparability of central corneal thickness (CCT) and keratometry measurements obtained by four different devices in healthy eyes. Methods. Fifty-five healthy eyes from 55 volunteers were enrolled in this study. CCT (IOLMaster 700, Pentacam HR, and Cirrus HD-OCT) and keratometry readings (IOLMaster 700, Pentacam HR, and iDesign) were measured. For statis...

The Astigmometer is a simple accessory which is attached to a surgical microscope. It allows precise suturing of the cataract wound and reduced the amount of postoperative astigmatism at six weeks. This allowed rapid visual rehabilitation and more active patients. It obviated the removal of sutures in the postoperative period in most patients (90%). However, stable results after one year were o...

BACKGROUND To evaluate the distribution of biometric parameters and corneal astigmatism using the IOLMaster device before phacoemulsification in cataract patients in Central China. METHODS Consecutive cataract patients were recruited at the Central Hospital of Wuhan between January 2015 and June 2016. Ocular axial length (AL), keratometry values, anterior chamber depth (ACD) and horizontal co...

AIMS A blind, randomised, prospective, bilateral study to investigate the efficacy of riboflavin/ultraviolet A corneal collagen cross-linkage to halt the progression of keratoconus. METHODS 24 patients with early/moderate bilateral keratoconus with recent progression were recruited. One eye was randomly assigned to undergo collagen cross-linkage following epithelial removal with riboflavin 0....

INTRODUCTION The biometric parameters of the eye are measured for the calculation of the intra ocular lens power to be used in cataract surgery. OBJECTIVE To report the keratometry reading, axial length and intra ocular lens power used for eyes operated for cataract in Karnali Zone, Nepal, and to compare these findings with those reported in other similar studies. SUBJECTS AND METHODS The d...
