Q: Are there any known and reported cases of allergy from foldable intraocular lens (IOL) implanted in the eyes? My mother got endopthalmitis after her phaco surgery but none of the other patients who got operated at the same day got the infection. The foldable IOL implanted was of rayner brand. Now her second eye is due for phaco surgery. Should I change the IOL brand or should I go for a non-foldable IOL?

A:Your concern for your mother's eye surgery is understandable, as this may be the only functional eye. She had endophthalmitis, and that is an infective condition and not an allergy. So no reason to be worried about the material on that ground. But you need to be concerned to avoid eye infection. Apart from local ocular asepsis, diabetes or any other focus of infection in the body needs to be excluded. Get her operated at a proper eye hospital.
