Description
The Optovue RTVue is an ultra-high speed, high resolution optical coherence tomography (OCT) retina scanner used for retina imaging and analysis.
It is based on the next generation Fourier-Domain Optical Coherence technology just emerging from clinical research in the last two years.
The ultra-high speed and high resolution features enable the FD-OCT to visualize the retinal tissue with ultra-high clarity in a fraction of seconds. myopic patients.
Tracking is available now for the Optovue RTVue SD-OCT.

Total Corneal Power
The Total Corneal Power Upgrade is the first FDA cleared SD-OCT based cornea power measurements which directly measures both the anterior and posterior curvatures rather than assuming an anterior/posterior relationship.
This methodology, coupled with 5 micron resolution SD-OCT technology, allows evaluation of post refractive patients with increased confidence.
Corneal powers from Optovue RTVue are entered into a unique online formula for IOL calculations.
Tracking
The Tracking feature for RTVue® provides exquisitely detailed B-scans of up to 16mm length. Capture high quality scans even on patients with fixation and movement issues as well as high myopic patients. Tracking is available now for the RTVue SD-OCT.
