A pupilloplasty is usually performed to repair damage to the iris and pupil after trauma. This procedure could also be necessary if an intraocular lens implantation leaves the pupil decentered. If the pupil is very far from center, the iris could create a shadow on the lens and a pupilloplasty would be able to return your vision to normal. This can improve light sensitivity and eliminate glares and halos caused by the irregular placing of the parts of your eye. An off-center pupil can also have cosmetic implications, so a pupilloplasty can render the pupil cosmetically more acceptable.
