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 Biometry. By optical biometry (Lenstar or IOLMaster), the challenges in measuring eyes with posterior staphylomata are often avoided. As long as the patient can see well enough to look directly at the small fixation light, the axial length measurement will be to the fovea, yielding the refractive, rather than anatomic, axial length.
