Twenty years ago corneal research and treatments looked very different. Contact lens or glasses were the norm and LASIK was only a dream. Large refractive errors were actually treated by using a procedure that froze, lathed and then sutured a piece of corneal tissue into the eye. There was no database to track corneal transplants and outcomes; most reports looked at small series within a year's follow-up. People with debilitating conditions, such as Fuch's dystrophy, keratoconus, and other ocular medical challenges, faced a full-thickness transplant with an arduous recovery.
