Horizontal Corneal White to White Diameter Measurements Using Calipers and IOLMaster

Abstract

To determine if the mean horizontal white-to-white (WTW) corneal diameter, measured intraoperatively with calipers, of a population of cataract surgery patients differs from the currently accepted normal WTW range of greater than 11.0 and less than 13.0 mm. In addition, we compared manual caliper measurements with those with IOLMaster.\r\r
