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.

Development of a Scheimpflug slit lamp camera system for quantitative densitometric analysis [PDF]

Eye, 1993
We have developed a computerised video system for accurate quantification of lens opacities from Scheimpflug images. Using a modified Zeiss Scheimpflug camera and Macintosh computer, the system software can warn of improper exposure and can provide immediate results of cataract progression on individual patients. These results are obtained from a novel
