Optical Biometry & Topography

Optical biometry is a highly accurate non-invasive automated method for measuring the anatomical characteristics of the eye. Accurate measurements are critical for determining the correct power of an IOL before it is implanted during cataract surgery.
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the anterior curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision and corneal health.
