Company Visiometrics
Item OQAS Optical Quality Analysis System
Features OQAS is specially designed for :
  • Comparing pre and post cataract and refractive surgery measurements
  • Diagnosis of pathologies
  • Right measurements of the ocular MTF (Modulation Transfer Function) in all situations (overestimated by aberrometers when scattering exists)
  • Showing the effect of ocular aberrations in visual acuity (including the higher order ones, not usually measured by standard aberrometers)
  • Objective measurement of the amplitude of accommodation
  • Showing the effect of accommodation in the quality of the retinal image
  • Objective measurement of halos and glare

OQAS provides:

  • Two and three dimensional maps of the retinal image, a qualitative way to evaluate the quality of the eye
  • The ocular MTF and other quantitative parameters useful for evaluating the performance of the eye
  • A dynamic register (video) of the retinal image
  • A useful and user-friendly patient database
  • Tools for optimum visualization and quantification of the images, such as zoom, rotation, profiles and measurements
  • Easy acquisition and manipulation of the images
Description OQAS (Optical Quality Analysis System) developed by Pablo Artal, PhD and Jaume Pujol, PhD is the first diagnostic tool for ophthalmology that provides "total optical quality of the total optical system. Never before has an ophthalmologist had the opportunity to truly understand a patients quality of vision.

OQAS works by sending in a near infrared light source and directly measuring the point-spread function of that reflected light source. Using Fourier analysis the point spread function data is translated to an MTF value. OQAS also provides full color, 3-dimensional views of the point spread function.

MTF values (the numeric translation of contrast sensitivity) are the basics of optical quality. For years the photography industry has used MTF values to measure the optical quality of lenses. The higher the MTF value, the higher the quality of the image after it passes through a lens. Transfer this optical knowledge to the eye and now we can know, for the first time, the total optical quality of the eye.

The superiority of OQAS over aberrometers is the ability of the OQAS to measure and analyze all orders of aberration PLUS scatter. Standard aberrometers are incapable of measuring higher order aberrations or scatter. To truly analyze your patients optical quality it is necessary to have complete information.

Applications include: screening of LASIK candidates, comparative studies of excimer lasers, IOL comparative studies, monitoring of cataract formation, comparative studies of different surgical techniques, and most importantly having an objective baseline of your patients optical quality. This objective analysis of optical quality can be used as an adjunct to your current subjective assessment of optical quality.
