Stretch technique helps manage small-pupil cases

Pupillary stretch is a safe and effective technique for expanding small pupils in cataract surgery, according to a study by Bradford J. Shingleton, MD. He measured the effect of pupillary stretch during phaco on postoperative vision, IOP and inflammation. No significant differences were seen between outcomes of cataract surgery performed with pupillary stretch or without, he said.

The retrospective study included 150 eyes in which pupil stretching was performed and 125 eyes in which no stretching occurred. All patients were followed for at least 1 year, Dr. Shingleton said.

Visual acuity was similar in the two groups preoperatively, and there was no statistically significant difference in visual acuity after surgery. A slight difference in IOP between the two groups was noted, but it was not statistically significant.
