The relationship between central corneal thickness and corneal curvature in adult Nigerians
African Vision and Eye Health, 2011 Purpose: The aim of this study was to provide average values for central corneal thickness (CCT) and corneal curvature (CC) and also to determine a regression model for the relationship between CCT and CC in adult Nigerians without glaucoma. Methods: A

Effects of rigid high gas-permeable contact lens wear on progression in patient with keratoconus
Medicine Science, 2022 Wearing Rigid High Gas-Permeable Contact Lens (RGPCL) is a primary method of vision rehabilitation in keratoconus eyes. The aim of the study is to investigate the effects of using RGPCL on the topographical variations at the keratoconus progress.

Keratometry in Pediatric Eyes With Cataract [PDF]
Archives of Ophthalmology, 2008 To report the keratometry data of pediatric cataractous eyes (randomly selected single eye of bilateral cases; cataractous eye of unilateral cases) and to compare the keratometry data of the unilateral cataractous eye with the corresponding noncataractous fellow eye.Retrospective review of preoperative data of patients who had undergone cataract ...

Keratometry device for surgical support [PDF]
BioMedical Engineering OnLine, 2009 High astigmatisms are usually induced during corneal suturing subsequent to tissue transplantation or any other surgery which involves corneal suturing. One of the reasons is that the procedure is intimately dependent on the surgeon's skill for suturing identical stitches.

The reproducibility of biometry and keratometry measurements [PDF]
Eye, 1991 Axial length and corneal curvature are entered into formulae to calculate intraocular lens power for cataract surgery and the absolute measurement of fundus structures such as neuroretinal rim area in glaucoma. The reproducibility (coefficient of variation, CV) of biometry and keratometry was investigated by taking five measurements of thirty phakic ...

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing
Acta Ophthalmologica, EarlyView.Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Agreement of Total Keratometry and Posterior Keratometry Among IOLMaster 700, CASIA2, and Pentacam
Translational Vision Science & Technology, 2023 The purpose of this study was to compare total keratometry (TK) and posterior keratometry (PK) obtained by two swept-source optical biometers (IOLMaster 700 and CASIA2) and one Scheimpflug-based topography (Pentacam AXL).The TK and PK in cataract surgery candidates obtained by IOLMaster 700, CASIA2, and Pentacam AXL were compared.
