Marco OPD Scan III is five tools in one. The doctors are extremely excited that this tool generates an abundant number of accurate data about the eye. Ultimately, the patient encounter will improve. Here is how:
Accuracy: This digital device can precisely pinpoint your eyesight prescription that is customized for clearer, clearer vision for the day and nighttime. We start the exam with this tool as it gives the doctor a baseline prescription which could reduce the “which is better 1 or 2” choices of a traditional exam.
Day and night vision: For those patients that complain of issues with night vision or night driving, two prescriptions may be beneficial. One prescription for one and afternoon vision for night vision. Due to this technology, our physicians now have the capability with the support of the eye test elements that are electronic and also to evaluate the need for a prescription, can formulate an accurate vision prescription.
Marco OPD Scan III Wavefront system from Nidek and Marco is a refractive power/corneal analyzer that can evaluate a patient’s overall visual system. It unites pupillometry, autorefraction/keratometry, corneal topography, optical path difference (OPD) and wavefront analysis into one diagnostic workstation.
New features include ARK function automation, wavefront visual acuity maps, a full 9.0millimeter measurement region, CT blue light and electronic medical record integration. In 10 seconds, Marco OPD Scan III may capture: the spherical aberration of the retina for aspheric intraocular lens choice; lenticular–remaining astigmatism; angle kappa; pre/post toric intraocular lens measurements; corneal pathologies; mesopic/photopic student size; retro lighting picture; Zernike graphs; corneal refractive power map; and intraocular lens tilt or decentration.
Marco OPD Scan III is 5 Instruments in 1
Aberrometer — evaluation of visual acuity and quality of vision. This measures how the light comes in and out of the pupil. If a patient is not fully correctable to 20/20 vision, our physicians have tools and data to educate the patient they are not fully correctable.
Topographer — maps the outside surface of the eye (cornea). Everybody’s eyes are exceptional. This measurement gives us a fingerprint of the eye’s top layer. Like the wavefront aberrometer, this informs us how light is currently passing through the eye. The doctor reviewed the pictures and compared to guarantee the eyes are healthy.
Auto-refractometer reading of prescriptions in nighttime and day conditions.
Auto-keratometer — an instrument for measuring the curvature of the cornea’s surface. This information is often used in the fitting of contact lenses as well as corneal changes’ monitoring.
Pupillometer -steps student diameters in the night and day.
The Marco OPD Scan III is a brand new topographer workstation based on the principle that is skiascopy. It unites pupillometer/pupillographer, topographer, autorefractor, auto keratometer and a wavefront aberrometer. Intra-session and inter-session variability have been assessed on 14 subjects (28 eyes).
The Marco OPD Scan III gave slightly more negative readings than results obtained by subjective refraction (Nidek mean difference -0.19 ± 0.36 DS, p < 0.01 for sphere; -0.19 ± 0.35 DS, p < 0.01 for mean spherical equivalent; -0.002 ± 0.23 DC, p = 0.91 for cylinder; -0.06 ± 0.38 DC, p = 0.30 for J0 and -0.36 ± 0.31 DC for J45 , p = 0.29). Auto-refractor results for 74 percent of spherical readings and 60 percent of cylindrical powers were within ± 0.25 of subjective refraction. There were high intra-session and inter-session repeatability for all parameters; 90 percent of inter-session repeatability results were within 0.25 D. The Nidek OPD-Scan III gives valid and repeatable measures of objective refraction when compared with non-cycloplegic subjective refraction.
