Comparison of Intraocular Lens Power Calculation Using Biometric Data From Pentacam AXL vs. IOLMaster 700 in Postphotorefractive Keratectomy Patients

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare intraocular lens (IOL) power calculation using biometric data from Pentacam AXL vs. IOLMaster 700 in postphotorefractive keratectomy (PRK) patients. Methods Patients with previous PRK and 1 year of postoperative follow‐up were included in the study.

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.

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.

Estimation of final cylindrical spectacle correction by Pentacam

Function and Disability Journal, 2020
Background and Objectives: Keratoconus is a non-inflammatory asymmetric corneal degenerative disease characterized by the steepening and distortion of the cornea. In this disease, irregular astigmatism makes the subjective refraction difficult. Using the

Zulu ocular biometry differs fundamentally from that of Europeans – A modelling analysis

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1829-1836, November 2025.
Abstract Purpose The accuracy of ocular refraction calculations depends on reliable biometry and the validity of the models upon which the calculations are based. Most models are based on European eyes, so their validity in sub‐Saharan Africans may be questioned, potentially contributing to suboptimal postoperative outcomes. Hence, this study developed

Fluctuations in angle lambda with the pupil diameter and correlations with biometric values in a healthy population

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1837-1844, November 2025.
Abstract Purpose Angle lambda (λ) is defined as the angle between the line of sight and the pupillary axis at the entrance pupil. We previously developed a child‐friendly and portable method to measure this angle in daily practice. In a given population, angle λ fluctuates according to age or refractive error.

Referat zur Diagnostik: Pentacam AXL

, 2018
Ein wesentliches Ziel in der Standard-Katarakt-Chirurgie ist es postoperativ die gewünschte Refraktion zuverlässig zu erreichen. Die Scheimpflug-Analyse mit der Pentacam AXL erlaubt neben der Achsenlänge und der Vorderkammertiefe, nicht nur die Keratometriewerte der kornealen Oberfläche,[zum vollständigen Text gelangen Sie über die oben angegebene URL]
