Accuracy of intraocular lens calculation formulas in cataract patients with steep corneal curvature

PLoS ONE, 2020
Objective To compare the accuracy of five kinds of intraocular lens calculation formulas (SRK/T, Haigis, Hoffer Q, Holladay and Barrett Universal Ⅱ) in cataract patients with steep curvature cornea ≥ 46.0 diopters. Methods This is a retrospective study of cataract phacoemulsification combined with intraocular lens implantation in patients with steep

Minimum Corneal Diameter and Anterior Steep Axis Curvature Share the Same Meridian: A Novel Finding

American Journal of Ophthalmology, 2023
To define the external scleral sulcus (ESS) on a Scheimpflug image and use it for a morphometric analysis of corneal diameter (CD).Retrospective, cross-sectional study of pediatric Asian-Indian eyes.One random eye of 353 subjects between 5 and 18 years underwent 25-scan Pentacam HR imaging.

Influence of Dry Eye Disease on the Measurement Repeatability of Corneal Curvature Radius and Axial Length in Patients with Cataract

Journal of Clinical Medicine, 2022
The influence of dry eye disease (DED) on ocular biometric measurements is unclear. We aimed to investigate the effect of DED on the repeatability of ocular biometric measurements in cataract patients.

Effects of steep-axis incision on corneal curvature in one-handed phacoemulsification

International Journal of Ophthalmology, 2019
To examine the effects of one-handed phacoemulsification with steep-axis incision on corneal curvature and analyze surgically induced astigmatism (SIA) on the true net power, anterior and posterior corneal surfaces.Patients with cataracts underwent one-handed phacoemulsification with a 2.4-mm steep-axis of clear corneal incision (CCI) based on true net

Modified deep anterior lamellar keratoplasty for the treatment of advanced keratoconus with steep corneal curvature to help in eliminating the wrinkles in the Descemet′s membrane

Indian Journal of Ophthalmology, 2014
To determine the clinical efficacy of modified deep anterior lamellar keratoplasty (DALK) for the treatment of advanced-stage keratoconus with steep curvature.In this interventional, non-comparative case series, 30 patients with advanced stages of keratoconus and curvature of more than 60 D underwent a modified DALK procedure.
