Exploring the Impact of Refractive and Ocular Residual Astigmatism on Stereopsis After Photorefractive Keratectomy in Patients With Myopic Astigmatism

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Background To investigate the impact of refractive and ocular residual astigmatism (ORA) on stereopsis after photorefractive keratectomy (PRK) for the correction of myopic astigmatism. Methods This prospective observational study was conducted on patients who underwent PRK for the treatment of myopia and myopic astigmatism using a Schwind Amaris 1050RS

Interocular Differences in Corneal Asphericity Are Associated with Stereopsis in Myopic Astigmatism Candidates for Laser Vision Correction

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To investigate the relationship between stereoacuity and corneal topographic parameters in patients with compound myopic astigmatism who are candidates for laser vision correction (LVC). Methods In this analytical cross‐sectional study, LVC candidates aged 18 years or older with compound myopic astigmatism and corrected distance visual acuity ...

Cataract Epidemiology Performed with Scheimpflug Documentation

Ophthalmic Research, 1999
Cataract epidemiological surveys applying a photodocumentation system were performed by the author’s group in three climatically different sites with racially different populations: Noto (Japan), Reykjavik (Iceland) and Singapore. Data regarding age- and sex-related changes in lens transparency decrease, prevalence and type of opacification are ...

A new method for Scheimpflug camera calibration [PDF]

, 2011
An easy way to achieve higher depth of field in a camera-laser configuration is to tilt the image sensor respect to the lens plane, such that the image plane, laser plane and the lens plane intersect in a unique line (Scheimpflug condition [1]).

Effects of customized corneal cross‐linking on higher‐order aberrations in progressive keratoconus and low‐grade myopia

Acta Ophthalmologica, Volume 103, Issue 8, Page 966-973, December 2025.
Abstract Objective To evaluate the effects of customized corneal collagen cross‐linking (CXL) on higher‐order aberrations (HOAs) in keratoconus (KC): vertical coma (VC), horizontal coma (HC), spherical aberration (SA), trefoil (TF) and astigmatism, compared with the same effects in healthy eyes undergoing CXL for low‐grade myopia.
