During intraocular surgery, an eyelid speculum is used to keep the eye open during surgery. Sometimes, the eyelid speculum can cause ptosis (droopy eyelid). This results from the speculum disinserting one of the muscles in the eyelid that works to elevate the eyelid.
Normally, we usually wait about six months following the surgery to see if the position of the eyelid returns to normal. If the ptosis persists beyond six months from the date of the surgery, then an eyelid surgery can be done to re-attach the muscle and elevate the position of the eyelid. This surgery is usually done by an Ophthalmologist who specializes in Oculoplastic surgery. This surgery is commonly performed and usually has excellent results.
