Discarded eye tissue yields clues about corneal strength in nearsighted patients

This study looks at tiny pieces of corneal tissue that are normally thrown away during a type of eye surgery for nearsightedness (myopia). Researchers will test the tissue's strength and structure in the lab and also use a special microscope to examine the living cornea before surgery. The goal is to learn more about how the cornea behaves mechanically, which may help improve future eye surgeries. About 100 people aged 20 to 50 who are scheduled for this surgery will take part.
