Comparisons of Intraocular Lens Calculation Formulas for Eyes With Astigmatism: Systemic Review and Network Meta‐Analysis

open access: yesJournal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the accuracy of different formulas for calculating toric intraocular lens (IOL) power. Methods PubMed, EBSCO, Web of Science, and the Cochrane Library were systematically searched for studies published from 2015 to 2025. Numbers of eyes with a prediction error (PE) within ±0.50 and ±1.00 diopters (D) were synthesized for the meta ...

Real-world refractive outcomes of toric intraocular lens implantation in a United Kingdom National Health Service setting

open access: yesBMC Ophthalmology, 2018
Background With increasing availability of toric intraocular lenses (IOL) for cataract surgery, real-world refractive outcome data is needed to aid the counselling of patients regarding lens choice. We aim to assess the outcomes of toric intraocular lens

Effect of Corneal Incision Features on Corneal Endothelial Cell, Astigmatism, and Higher‐Order Aberrations After Implantable Collamer Lens Implantation

open access: yesJournal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose This study evaluated the impact of clear corneal incision (CCI) morphology on corneal endothelial cell density (ECD), astigmatism, and higher‐order aberrations (HOAs) following implantable collamer lens (ICL) implantation. Design Prospective study. Methods Sixty‐five patients (65 eyes) undergoing ICL implantation were included.

Development and management of surgical techniques for toric intraocular lenses in patients with compromised capsular integrity

open access: yesYanke Xuebao
Astigmatism is a common form of refractive error. For patients who also have cataracts, implanting a Toric intraocular lens (Toric IOL) offers an effective solution.

Prospective evaluation of a plate haptic toric intraocular lens [PDF]

open access: yesEye, 2001
Standard intraocular lenses (IOL) only correct the spherical component of aphakic refractive error. This study describes clinical experience with a foldable, injectable, toric IOL.Keratometric, refractive and visual data were collected on patients listed for cataract surgery.

The effects of a HEV‐filtering contact lens on the brightness of natural images

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 7, Page 1801-1810, November 2025.
Abstract Purpose Yellow filters, including high‐energy‐visible (HEV) filtering lenses, have been thought to increase the subjective brightness of real‐world scenes, but laboratory results are mixed. This study used a brightness matching technique modified to present natural images using a broad spectrum of wavelengths: a visibly clear control contact ...

Deciphering the performance of different surface models for corneal topography

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 6, Page 1270-1281, September 2025.
Abstract Purpose To study the performance of different corneal surface models to be used for ray tracing. Models based on geometric surfaces and polynomial fits were compared and the differences discussed. Methods For this simulation study, five characteristic generic surface configurations were generated: (A) perfect biconic, (B) decentred biconic ...

Presbyopia Correction in Lens Replacement Surgery: A Review

open access: yesClinical &Experimental Ophthalmology, Volume 53, Issue 6, Page 668-681, August 2025.
ABSTRACT Presbyopia affects approximately 1.8 billion individuals globally, posing significant challenges as life expectancy and near‐vision demands, particularly with mobile phone use, grow. Addressing presbyopia during lens replacement surgery has become a key focus for cataract surgeons, aiming to reduce dependence on corrective eyewear. This review
