Iris reconstruction by coloboma repair.

If a pupil becomes irreversibly miotic during cataract surgery it is helpful to perform an iridotomy to facilitate lens expression. Reconstructing the pupil with one or two iris sutures is advisable in order to prevent coloboma-related problems. We describe a method of iridoplasty that involves using a vanadium steel suture attached to a long, straight needle. This technique can be used in an eye with surgically low pressure as well as in an eye with elevated vitreous pressure.
