Actually, removing cataract is not only to remove the opacity, but also to restore the visual capacity of the eye without the aid of glasses or contact lenses.
The more accurate the calculation of the intraocular lens to be implanted, the better the functional result that will be obtained.
Methods for Biometrics
IMO has two different methods for Biometrics:
A classical method that uses ultrasounds to measure the axial length of the eye and the depth of the anterior chamber, introducing the remaining variables – diopter power of the cornea – measured in other equipment.
IOL Master (Zeiss) and AL-Scan (Nidek) – Optical coherence Biometry – the most recent method that performs, with more accuracy, all the measurements necessary to calculate the ideal intraocular lens to be implanted in each proposed case for cataract phacoemulsification surgery or transparent lens surgery.
