Statistics from the past decade indicate that there were fewer corneal transplants performed in the U.S. in 2000 (33,260) than in 1990 (36,037). During this decade, the distribution of corneas for transplant to international sites increased steadily, which more than accounts for the difference. In 1990, 2,726 corneas were exported (7% of the total). Ten years later, the figure exported was reported at 13,689 (29% of the total). Thus, in the year 2000, growing international demand contributed to an increase in the total amount of tissue provided for transplant: 46,949 compared with 38,762, in 1990

Use a search engine like Google and look up keratoconus and you can find all you want to know. Also use Google images to see pictures of how the cornea changes in shape.
