REFRACTIVE ERRORS

This study is testing whether providing free reading and distance glasses can help slow down memory loss and cognitive decline in older adults. Researchers in India will give glasses to 820 participants aged 60 and over who need them and follow their health for three years. The m…

This study is testing the safety and precision of a new ultraviolet laser for creating the corneal flap during LASIK surgery. It will compare this new laser to the current standard infrared laser in 174 participants in Australia. The main goal is to see if the new laser can creat…

This study aims to check how well a computer program can predict vision results after a common type of laser eye surgery (PTK-PRK). Researchers will collect data from 150 patients with nearsightedness who have already had the surgery as part of their normal care. They will compar…

This study aims to understand if common vision correction surgeries like LASIK change the results of a key eye scan called OCT. Researchers will measure the eyes of 33 people before and after their surgery to see if the scan readings are different. The goal is to make sure these …

This study aims to understand if the size and shape of a person's eye is related to the three-dimensional shape of their face. Researchers will examine 120 healthy young adults (ages 21-25) who have either normal vision, are nearsighted, or are farsighted. They will use a routine…

This study aims to develop better tools to predict how a person's cornea will respond to surgery. Researchers will use special eye imaging and computer simulations on people with keratoconus or those scheduled for LASIK. The goal is to see if these computer models can accurately …
