While you're researching the scleral lens you might want to try a less expensive lens to see if it will help you. I had a lens for about 3 years that was similiar to the scleral, didn't have to have it fitted so I took it home with me on the first visit. My regular eye doctor sent me to an eye doctor that specialize in dry eye issues. He told me not to bother making an appointment because she probably couldn't help me. I was at my wits end so he referred me to her but sent information rather than making an appointment. She told me she could help me, I got my Jupiter 15 lens and was very happy with it. The lens is a hard contact lens like the scleral lens but not as big. After about 3 years I couldn't wear the lens anymore, not sure why, perhaps I became allergic to it. Anyway, my eye doctor then had me try using a daily use contact lens. I use the Acuvue Oasys, it just came out this time last year. I love it, can't tell it's in my eye and I don't have to use all the cleaning solutions I did with the scleral lens. Depending on your Insurance it can be a bit costly, the lens costs about a dollar a day. For me it's wonderful, before the daily use lens and the Jupiter lens I spent over $4,000. a year on eye ointment, that's not a typo. There is something out there that will work for you, keep researching and don't stop because a doctor says it won't work for you. Good luck and keep us updated! Jill
