Avoiding complications associated with iris retractor use in small pupil cataract extraction.

While there are several options for managing the small pupil during cataract surgery, adjustable iris retractors are beneficial when there is a risk of cutting or tearing the iris, such as with rubeosis. Appropriate use of this new surgical tool includes proper placement of the parcenteses and a gradual and limited enlargement of the pupil, perhaps to no more than 5.0 mm.
