Abstract
Ocular biometry is a diagnostic method in ophthalmology that uses various techniques to measure the different parts of the eye. It involves the use of instruments that can measure the axial length of the eye, corneal curvature, anterior chamber depth, and other parameters related to the eye's structure. Ocular biometry is crucial in diagnosing and monitoring various eye conditions, especially cataracts but also glaucoma, and myopia. One of the most important techniques used in ocular biometry is optical biometry. Optical biometry involves the use of specialized devices that use light to measure the length of the eye. This technique is very accurate and is the gold standard in measuring axial length, which is essential in determining the correct power of intraocular lenses for cataract surgery as myopia and macular degeneration. Another technique used in ocular biometry is acoustical biometry. This technique uses sound waves to measure the axial length of the eye. Today, acoustical biometry is less commonly used than optical biometry but is still an important tool in certain cases. For example, in eyes with dense cataracts, where the optical media is opaque, acoustical biometry may be the only option for accurate measurement. This talk summarizes the up‐to‐date techniques in ocular biometry is an essential tool in ophthalmology for accurate diagnosis, monitoring, as well as treatment of various eye conditions, and addresses pit and pitfalls.
