Description
The radiuscope has traditionally been the gold standard of base curve measurement in many clinical settings (Defazio and Lowther, 1979; Rakow, 1985; Tannehill and Sampson, 1966). Keratometry has traditionally been performed with manual instruments. Numerous . studies have proven the effectiveness of autokeratometers, both stand and hand held models, in the measurement of both corneal curvature and on man made surfaces (Pardhan and Douthwaite, 1998; Harvey et al., 1995; Lam, 1995; Douthwaite and Pardhan, 1995, 1997; Tennen et al., 1995; Wassill and Dick, 1995). The purpose of this study is to bridge the gap between these two instruments and test the accuracy of a hand held autokeratometer in comparison to a standard radiuscope.
