I just got my low profile platinum implant on August 12. I can keep my eye open fine, it now closes all the way, and I blink about half-way. If it were heavy enough for me to blink all the way, I think my eyelid would droop. So there's a tradeoff involved.
I found the surgery to be very easy. I did not even get a black eye. I am still using ointment at night and drops during the day, but not nearly so much. I have made a few posts about my experience. I posted a picture in the follow-up one.
They can be removed once the blink function returns to normal. My ophthalmologist told me I would ask to have it come out a long time before he would agree to do so. He says he has seen too many people have it removed and then regret it. Also, the eye and forehead are the last regions to regain movement. I will probably leave mine in unless my eyelid gets really droopy.
I wish I had gotten it right away instead of waiting 10 weeks.
Pros: eye feels and looks better, use fewer drops, less chance of corneal abrasion
Cons: it is another surgery, some people have allergic reactions, especially to gold (that's why my ophthalmologist uses platinum), can make eyelid droopy, can shift or extrude over time
Best wishes!
