Acta Ophthalmologica, EarlyView.Abstract While acanthamoeba keratitis (AK) is a sight‐threatening corneal infection, a thorough comparison of the outcomes of therapeutic penetrating keratoplasty (PK) and therapeutic deep anterior lamellar keratoplasty (DALK) is lacking. We aimed to compare clinical outcomes of PK and DALK in AK.

Premium Intraocular Lens Selection in Patients With Glaucoma: A Clinical Review
Clinical &Experimental Ophthalmology, EarlyView.ABSTRACT Glaucoma frequently coexists with cataract, but glaucomatous functional loss, ocular‐surface disease, anatomical abnormalities, and treatment‐related refractive variability may reduce tolerance of premium intraocular lenses. This narrative review critically appraises evidence relevant to lens selection in glaucoma. Central visual‐field status,

A New Approach for the Calculation of Total Corneal Astigmatism Considering the Magnitude and Orientation of Posterior Corneal Astigmatism and Thickness [PDF]
Cornea, 2018 Purpose: To evaluate a new method of calculation of total corneal astigmatism based on Gaussian optics and the power design of a spherocylindrical lens (C) in the healthy eye and to compare it with keratometric (K) and power vector (PV) methods.

Reduced order modelling of air‐puff test for corneal material characterisation
Journal of Microscopy, EarlyView.Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress
Advanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Understanding higher‐order aberrations in keratoconus
Optometry and Vision Science, Volume 103, Issue 10, October 2026.ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Gender-differences in age-related changes of corneal astigmatism in Korean cataract patients
BMC Ophthalmology, 2019 Background This cross-sectional study investigated age-related changes in anterior, posterior, and total corneal astigmatism and evaluated sex differences in corneal astigmatism with increasing age in cataract patients.

Repositioning of Vertical Implantable Phakic Contact Lens
Clinical Case Reports, Volume 14, Issue 9, September 2026.Vertical orientation of Implantable Phakic Contact Lens. ABSTRACT Implantable phakic contact lens (IPCL) V2.0 has a special patterned hole on the leading left corner to ensure correct orientation and positioning. Incorrect orientation is an absolute indication for repositioning.
