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 ...

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.

Polar Value Analysis of Low to Moderate Astigmatism with Wavefront-Guided Sub-Bowman Keratomileusis
Journal of Ophthalmology, 2017 Purpose. To evaluate the astigmatic outcomes of wavefront-guided sub-Bowman keratomileusis (WFG-SBK) for low to moderate myopic astigmatism. Methods. This study enrolled 100 right eyes from 100 patients who underwent WFG-SBK for the correction of myopia ...

Eye &ENT Research, Volume 3, Issue 3, Page 168-174, September 2026.ABSTRACT Background Keratoconus is a progressive corneal ectatic disorder. Accelerated transepithelial corneal cross‐linking (ATE‐CXL) aims to halt progression while preserving the epithelium, but evidence on its 12‐month efficacy requires further evaluation.

Annals of Eye Science, 2018 Background: In recent years posterior corneal astigmatism and its effect on total corneal astigmatism has been studied, with research showing that this can impact total astigmatism. This study aims to ascertain if there is significant change in the posterior corneal astigmatism after cataract surgery and its impact on the total astigmatism.

Slowing of myopia progression by spectacles with highly aspherical lenslets—A narrative review
Optometry and Vision Science, Volume 103, Issue 9, September 2026.ABSTRACT Purpose A new generation of myopia control spectacles has emerged, including spectacle lenses with highly aspherical lenslet technology (HAL lenses). To date, HAL lenses have only been thoroughly evaluated in a single site randomized clinical trial in China and a recently published, multicenter, North American clinical trial.

Clinical &Experimental Ophthalmology, Volume 54, Issue 7, Page 955-973, September/October 2026.ABSTRACT Several benign, inflammatory and malignant lesions can present as iris or anterior chamber masses, including iris naevi, cysts, adenomas, leiomyomas, nodules, vascular tumours, melanomas, metastases, as well as iris and pigment epithelium adenocarcinomas. Fortunately, benign iris lesions are much more common than malignant tumours and many can

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing
Acta Ophthalmologica, Volume 104, Issue 5, Page 498-509, August 2026.Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.
