OCT angiography has potential to improve diagnosis and monitoring of corneal vascularization

OCT angiography is designed and optimized for the retina, but it offers potential for the diagnosis and monitoring of several conditions that affect the cornea, according to one specialist.“With a modified focus and algorithm, OCTA can be used for imaging and delineating corneal vascularization, which is seen in any insult to the cornea, including patients with ocular surface disease and limbal stem cell deficiency,” Marcus Ang, FRCS, said in an interview with Ocular Surgery News.

Hyperopic LASIK with corneal vertex centration minimizes postop higher-order aberrations

LASIK for high hyperopia with corneal vertex centration and asymmetric offset yielded a low risk of postoperative higher-order aberrations, according to a study.“Maintaining postoperative keratometry less than 49 D after hyperopic LASIK and centering on the corneal vertex reduces the induction of coma compared to non-aspheric profiles and lower hyperopia,” the study authors said. “The use of corneal vertex centration results in a morphologically stable cornea, less topographic asymmetry and enhanced stability.”
