Optical Biometry Versus Ultrasound Biometry [PDF]

The Egyptian Journal of Hospital Medicine, 2020
Background: Implantation of an intraocular lens (IOL) is the gold standard in modern-day cataract surgery. Over the last decade, IOL power calculations have become a focal point of cataract surgery. Objective: To compare the sensitivity and specification of optical biometry and applanation ultrasound biometry in the measurement of intraocular lens ...
