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

The influence of posterior corneal surface astigmatism on residual astigmatism [PDF]
, 1990 It has often been found that corneal astigmatism exceeds the amount exhibited by the eye as a whole. This difference is usually referred to as residual astigmatism. Scrutiny of the studies of corneal astigmatismreveal that what has actually been measured is the astigmatic contributionof the anterior corneal surface alone.
