Hello everyone,

Long-time lurker first time poster...licensed skydiver. I'm interested
in becoming a pilot (age 47) but given that my best corrected vision in
my left eye is 20/40 and usually 20/50 (with hard contacts) as a result
of keratoconus. I'm anticipating the need for a corneal transplant
therefore to get the left eye to acceptable params. Has anyone here had
or know of anyone who has had such surgery and become/maintained flight
status?

Richard, you have a special situation. You certainly don't want to fly
if you are not safe. "Self certifying" does not lower the requirements.
So spend a few bucks and chat with an Aviation Medical Examiner. You
don't have to request a medical certificate so there is no risk. Good luck.
