MSRP:
The Marco OPD-Scan III is an autorefractor, keratometer, pupillometer (up to 9.5mm), corneal topographer, and integrated wavefront aberrometer. It can complete 20 diagnostic metrics in less than 10 seconds per eye (including angle kappa, angle alpha, HOAs, average pupil power, RMS value, and point spread function). Plus, easy and automatic alignment and data capture ensures accurate results.

Fast, Accurate Diagnostics
Over 20 diagnostic measurements are acquired in 10 seconds with the OPD-Scan III. Easy alignment and automatic capture of data ensures accurate readings. Wavefront data is gathered with 2,520 light vector data points from available zones up to a 9.5mm area, adding the capability to provide for calculation of mesopic refractions. Corneal topography is gathered across 11mm with 11,880 data point mapping. Blue light, 33 ring, placido disc topography is gathered in one second.

Unique Features for Cataract & Refractive Surgery
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 positions. Retro illumination images can be used post-op to verify IOL axis alignmen
Dysfunctional Lens Syndrome (DLS)
The map pictured 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 has changed. A refractive lens exchange is recommended.
Day/Night Wavefront Refractions
Pupillometry measurements are utilized to allow for the calculation of separate wavefront refractions at 4mm and 6mm zones (or mesopic if smaller than 6mm). This provides information on the stability of the refractive error as pupil size changes, and the individual starting points for separate day and night refractions, if indicated. Your patients can receive a state-of-the-art printout of their ‘before’ and ‘after correction’ chart or understand why they are not able to achieve 20/20.
