Central vault after phakic intraocular lens implantation : correlation with anterior chamber depth, white-to-white distance, spherical equivalent, and patient age [PDF]

, 2012
To compare the central postoperative vault of a phakic intraocular lens (pIOL) to correct myopia, myopic astigmatism, and hyperopia and identify ocular and lens parameters that might predict the vault amount.Supported in part by Ministerio de Ciencia e

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

Journal 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 ...

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

Journal 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.

Urrets-Zavalia syndrome following implantable collamer lens (ICL) implantation: a case report and review of the literature

Journal of Medical Case Reports
Background Urrets-Zavalia syndrome is a condition that arises after eye surgery, often linked to increased intraocular pressure following the procedure. We present a case of a progressively dilated and fixed pupil in one eye following the implantation of

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

Ophthalmic 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

Ophthalmic 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 ...

Surgical technique for management of isolated lenticular coloboma with high corneal astigmatism

Indian Journal of Ophthalmology, 2018
We describe a surgical technique for the correction of isolated congenital lenticular coloboma associated with high corneal astigmatism. Transscleral fixation of the capsular bag with a single eyelet Cionni capsular tension ring was followed by in-the ...
