KERATOCONUS

This study tests whether strengthening donor corneal tissue with a cross-linking procedure before transplant can improve vision and reduce astigmatism in people with keratoconus. About 216 adults aged 18-50 who need a cornea transplant will take part. The goal is to see if this p…

This study looks at how a surgery called CTAK (corneal tissue addition for keratoplasty) affects vision and quality of life in people with keratoconus, a condition where the cornea becomes thin and cone-shaped. Researchers will ask 100 participants to fill out questionnaires befo…

This study will develop an artificial intelligence (AI) system to detect common eye diseases like glaucoma, cataracts, and diabetic retinopathy. Researchers will use 15,000 existing eye images from two clinics in Costa Rica, without recruiting new participants. The goal is to cre…

This study tests a new type of contact lens with a tiny central opening, designed to improve vision for people with presbyopia (age-related blurry near vision) or keratoconus (a condition where the cornea bulges). The lens works like a pinhole camera to increase depth of focus an…

This study will measure how eye pressure changes in one person with mild keratoconus after they receive corneal cross linking. The pressure will be checked before the procedure and again one month later using a special device called Corvis CT. The goal is simply to observe and re…

This study will follow 421 people with keratoconus, a condition that thins and bulges the cornea, to learn how it progresses and what factors increase risk. Researchers will track changes in eye shape and vision over time. The goal is to improve how doctors manage the disease and…
