Biometry

Measurement of the internal dimensions of the eye, performed as a part of IOL power calculation. The ocular axial length measurement is used in one of several mathematical formulas to calculate the proper power of lens implant to be used in cataract surgery. Biometry can be performed either by ultrasonic instruments (called “A-scans”) or by optical coherence tomography. Dr. Wallace is one of the co-inventors of the Bio-Pen , the smallest and most accurate instrument of its’ kind.
