WebData quality for optical biometry is frequently diminished in cases of very dense cataracts and posterior subcapsular cataracts, and this can be quantified in the form of signal-to-noise ratio (SNR). 7–9 Olsen et al reported a minimum difference in axial length (AL) between optical biometry and US at an SNR value of ≥2.1. WebOptical biometers are used to perform ocular biometry that measures the length of the eye, curve and width of the cornea, and anterior chamber depth. This information is normally used before refractive or cataract surgery to determine the intraocular lens (IOL) power a patient requires.
