Modified technique using flexible iris retractors in clear corneal cataract surgery.

Flexible nylon iris retractors are a useful adjunct to cataract surgery in cases of small pupil. We present a modification of the standard technique. Instead of approaching the square-shaped pupil formed by iris retractors from the side, we recommend an approach anterior to 1 of the retractor hooks. From the surgeon's viewpoint, the pupil goes from a square shape to a diamond shape. This modification minimizes the likelihood of iris prolapse and iris damage during phacoemulsification and increases the workspace for the phacoemulsification needle.
