Accuracy and reliability of orthogonal polynomials in representing corneal topography

Medicine in Novel Technology and Devices, 2022
Fitting of corneal topography data to analytical surfaces has been necessary in many clinical and experimental applications, yet absolute superiority of fitting methods was still unclear, and their overfitting risks were not well studied.

INFLUENCE OF TOPICAL ANAESTHETICS ON CORNEAL TOPOGRAPHY

Офтальмохирургия, 2015
Introduction. By now it is a well-established fact that topical anaesthetics have an influence on IntraOcular pressure. The topical anaesthetic will give a lower intraocular pressure reading.

Optical coherence tomography-based topography determination of corneal grafts in eye bank cultivation

Journal of Biomedical Optics, 2017
. Vision loss due to corneal injuries or diseases can be treated by transplantation of human corneal grafts (keratoplasty). However, quality assurance in retrieving and cultivating the tissue transplants is confined to visual and microbiological testing.
