Optical Biometer
Ocular biometry refers to the measurement of anatomical dimensions of the eye, which include corneal curvature (keratometry), axial length, and anterior chamber depth. These measurements are primarily used to calculate the appropriate power of the intraocular lens (IOL) to be implanted during cataract surgery.
What is Optical Biometer?
Optical biometry is a non-contact automated modality used for measuring optical biometric parameters. Two models are widely available that employ two different techniques: Laser partial coherence interferometry (PCI) and optical low-coherence reflectometry (OLCR).
What machine is used to check your eyes?
A non-contact optical device that measures the distance from the corneal vertex to the retinal pigment epithelium by partial coherence interferometry, the IOL Master is consistently accurate to within ±0.02 mm or better. The IOL Master is the first such device to be widely used in clinical ophthalmology.
