Large upper eyelid coloboma repair: a one-stage, one-site technique.

Current techniques for repairing large eyelid colobomas require preparation of other tissue sites and occasionally more than one procedure. We present a technique that requires only one procedure and is limited to the colobomatous eyelid; in addition, it is specifically designed to help avoid postoperative astigmatic and obstructive amblyopia. Outcomes are demonstrated in 3 cases of hemifacial microsomia. Large colobomas on the upper eyelid can be successfully and aesthetically repaired with only one procedure, incising only the congenitally abnormal eyelid.
