Biometry and Intraocular Lens Power Calculation
摘要
Cataract surgery is one of the most common surgical procedures performed worldwide [1]. Along with removing the cataractous lens, cataract surgery aims to provide clear vision to the patient with or without glasses. Therefore, accurate intraocular lens (IOL) power calculation is essential. The refractive power of the eye primarily depends on the cornea, the lens, the ocular media, and the axial length (AL) of the eye. Hence, the corneal curvature, the anterior chamber depth, and the AL should be accurately measured to precisely calculate the power of the IOL to be implanted and its final position in the eye. The power of the IOL is calculated from these parameters.
