Monnett Eye & Optical Center

In lens-replacement procedures, vision is improved by replacing the eye's natural lens with an intra-ocular lens (IOL). IOLs come in different powers and sizes to compensate for each patient's individual needs. There are many options available, how do you know the right one?

Today, selecting the right IOL to meet individual patient expectations is more crucial than ever. The IOLMaster 500 incorporates advancements designed with the challenges of today‘s cataract practice in mind: precision, simplicity, outcomes.


Monnett Eye Care is proud to offer the new IOL master technology for extremely accurate measurement of the axial length used for intraocular lens power calculations (the custom power of the implant for an individual’s eye).

This device uses partial coherence interferometry to measure the length of the eye (as opposed to standard ultrasound measurements). It has an accuracy of +/- 0.02 mm or better! This represents a fivefold increase in measurement accuracy when compared to standard A-scan ultrasound (which has a resolution of +/- 0.1 to 0.12 mm).


We have invested in this new technology because we feel it will improve our ability to calculate implant powers with even greater accuracy! This helps our cataract surgical patients have better distant vision without glasses by improving our accuracy in choosing the best implant for the patient’s eye.
