Optical biometry is the current standard for intraocular lens (IOL) power calculations in clinical practice. Optical biometry is a highly accurate non-invasive automated method for measuring the anatomical characteristics of the eye. Accurate measurements are critical for determining the correct power of an IOL before it is implanted during cataract surgery .
Optical biometry, also known as ophthalmic biometry, using partial coherence interferometry has become the gold standard in ocular biometry as it is highly accurate, easy to perform, non-invasive and comfortable for the patient. The use of optical biometry is a valuable tool when planning cataract surgery and refractive procedures like ICL, resulting in optimization of patient outcomes.
