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.

Measurement of corneal astigmatism
Chinese Science Bulletin, 1998 Cornea is the most inportant optical surface in the eye dioptric system. Three kinds of methods in measuing corneal astigmeatism wre used. Three hundred and sixty eyes suffered ametropia were selected on a random basis. Computer-assisted corneal kpographic system was compared with keratometer and cycloplegic retinoscopy in measuring corneal curvature ...

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.

UP Journal of Ophthalmology, 2023 Corneal astigmatism is a refractive error that creates an asymmetric blur in the vision. Corneal astigmatism can arise from trauma, disease, following surgery, or be congenital. In assessing corneal astigmatism, a decision should be made as to whether the astigmatic pattern is regular or irregular.

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

Clinical &Experimental Ophthalmology, Volume 54, Issue 7, Page 883-894, September/October 2026.ABSTRACT Background To report the 1‐year clinical outcomes of decellularised human corneal stromal lamina implantation, with or without autologous adipose‐derived adult stem cells (ADASCs), for advanced keratoconus in a European cohort. Methods In this prospective, randomised Phase I/IIa trial, 10 eyes of 10 patients were allocated to decellularised ...

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.
