Optical biometry is the standard test to calculate the power of the intraocular lens (IOL) to be implanted instead of the crystalline. It is a very accurate, non-invasive automated examination to measure the anatomical features of the eye. Accurate measurements are crucial to determining the correct power of the IOL before being implanted during cataract surgery. It’s a non-invasive, comfortable exam.

The accuracy of biometrics, especially the IOL Master, has been highly confirmed through a broad spectrum of studies. It performs anatomical measurements of the eye including axial length, keratometry and depth of the anterior chamber. These measures are indispensable to choose the right value of the IOL to be implanted to achieve the desired refractive result after cataract surgery. Therefore, it is a fundamental examination before cataract surgery.
