Abstract Details


To present own technique for intraoperative trimming of artificial iris (initial diameter 2.8mm) according to the WTW of the patient


Ophthalmology Clinic, Athens Metropolitan Hospital


The artificial iris (Humanoptics, Germany) is manufactured as a standard diameter of 2.8mm . To trim, 0.5mm is added to the average of the horizontal and vertical WTW diameter of the eye. Half of the resulted diameter is adjusted on a caliper. The caliper is centered in the center of iris and circular perforations on the iris tissue are made every 15-20 degrees. Tracing and connecting these perforations the iris is cut circumferentially with Vannas scissors to the appropriate size.


This novel method is applied to 6 artificial irises. The diameter of all trimmed irises had less than 1 mm difference from the intended cut. No movement of artificial iris was observed in any of the eyes three months postop.


This novel technique for artificial iris trimming can replace trephine cuts accurately in cases where these are not available.
