THE NIDEK MARCO CORNEAL ANALYZER OPD SCAN III IS THE LATEST DIAGNOSTIC/REFRACTIVE INSTRUMENT THAT SERVES THE PRACTICE AS AN AUTOREFRACTOR, KERATOMETER, PUPILLOMETER, CORNEAL TOPOGRAPHER AND WAVEFRONT ABERROMETER
Accurate Diagnostics
Over 20 diagnostic measurements are acquired in 10 seconds. Easy alignment and automatic capture of data ensures accurate readings. Wavefront data is gathered from available zones up to a 9.5mm area, adding the capability to provide for calculation of mesopic refractions. Blue light, 33 ring, placido disc topography is gathered in one second.
Data View Options
Axial, gradient, instantaneous, numeric K display, numeric power display, PSF (point spread function), zernike graph (including corneal), contact lens summary, VA-ETDRS simulations, internal OPD, eye image, comparison maps, and difference maps.
Unique Features
Cataract and refractive surgeries have now been taken to another dimension. Detailed patient summaries are available in just a matter of seconds. Pre-op toric axis alignment can be mapped to iris or other physical landmark positons. Retro illumination images can be used post-op to verify IOL axis alignment.
Dysfunctional Lens Syndrome (DLS)
The above map is a measurement of a prior myopic LASIK patient with Dysfunctional Lens Syndrome (DLS). The Point Spread Function (PSF) maps show that the cornea is contributing to the problem but the majority of the patient’s issue is lenticular change. The patient thought she needed another LASIK treatment, when in actuality, the lens changed. A refractive lens exchange is recommended.
