Abstract
• Ocular biometry is an essential procedure in ophthalmology as it is used to calculate the optical power of intraocular lens that replaces the cataract lens in pseudophakic cataract corrections • Biometric data are important such as Axial length, keratometry values, Anterior chamber depth, corneal power are necessary parameters for IOLs power calculation and for satisfied outcomes after IOLs implantation • Biometry can be performed by both ultrasonic and optical biometry but non-contact optical methods (IOL Master700 and the Lenstar900) are now preferred due to their significantly higher resolution, better patient comfort and greater acceptability • IOL Master uses the partial coherence interferometry technology for AL measurements with automated keratometry, ACD and corneal white to white distance measurements in one instrument • The Lenstar 900 is based on optical low coherence reflectometry can provide a nine accurate measurements such as AL, ACD, lens thickness and , keratometric readings, corneal diameter, pupil size and retinal thickness at the point of fixation.
