Hi MMario. The options I'm aware of are these:

No implants, no contacts, but special glasses. With this option, I'm assuming that I wouldn't be able to see much without the glasses.

Contact lenses. I have some concern about chemical sensitivities with this option, but not as much as with the implants. Again, I'm assuming that I wouldn't be able to see much without the contacts.

Implants. This sounds like it would be the best option if my body would be able to tolerate the implants.

Preventative maintenance. Try, through the use of sun-glasses and vitamins, to put off needing the surgery.
