Biometry optical
WebBoth the ultrasound and optical biometry groups demonstrated similar levels of achieving the standard benchmarks for individuals attaining a final spherical equivalent within 1.00 dioptre of the predicted refraction (90.7% with ultrasound biometry vs. 93.6% with optical biometry) and within 0.50 dioptres (68.2% with ultrasound biometry vs. 72.7 ... WebIn Optical biometry, light is reflected rather than sound. There is no contact with your eye as a special camera does the work of the probe. The results are entered into a computer which provides a measure of the distance between the various intra-ocular structures. This test takes about 10 to 15 minutes.
