Protection against small iris-prolapse and its repositioning... 

Pupil distortion may be caused by many factors. If a wound leak is present, a wick of vitreous or prolapsed iris may become incarcerated in the wound, causing a distorted or peaked pupil. The peak of the pupil often points toward the incarcerated area (Figure 30-6). 

The patient may or may not have symptoms from pupil distortion. Clinically, the pupil and anterior chamber should be eraluated before dilation. If the pupil is peaked at the first postoperative visit, the examiner may carefiilly examine with gonioscopy, looking for vitreous or iris extending to the wound. Presence of vitreous prolapse in the anterior chamber necessitates a thorough retinal eraluation early in the postoperative period, looking for secondary retinal breaks. lOL position and capsule integrity should be eraluated to further define the source of pupil distortion.
