Measure image using the Visante OCT analysis software before and after acquisition. Practical tools measure ocular structures-ACD, anterior chamber angles and anterior chamber diameter. Corneal Imaging and Pachymetry. High resolution Supported documentation for ocular health. Rapid pachymetry scan Accurate and repeatable map result for glaucoma care. New Lasik information. Visante is the first non-contact OCT to capture, measure and document both corneal flap thickness and residual stromal thickness immediately after LASIK surgery.
Safety and stability of Lasik flaps will not be compromised due to the Visante complete non contact system. The preset radial axis lines start at the 0 degrees and rise at The Global Pachy Map is able to provide twice as many data points and therefore a more detailed evaluation. The repeatability of the Visante pachy map in the standard mode was noted at 7 micron standard deviation in the center and 14 micron standard deviation in the periphery.
As the optometer changes focus, accommodation can be induced and as such dynamic changes of the anterior segment can be quantitatively measured. In the Visante 2. In the Enhanced mode, four consecutive scans are performed and compressed into a single image to produce a higher density, higher contrast image.
Additionally, new software tools to produce a phakic IOL template and measurement tools for endothelial clearance and lens vault distance, along with more sophisticated angle measurement tools are among the many enrichments that have been devised. Visante Anterior Segment OCT images can be used in evaluation of the refractive patient, both pre-operatively and post-operatively. It is capable of providing broad overview images of the anterior segment and more detailed high resolutions of specific areas.
Pachymetric mapping, angle evaluations, corneal flap evaluations, and phakic IOL templates are some of the useful features that will be demonstrated in examples in the remainder of this chapter. The latest 3 models, the , , and the are capable of linking data with the Visante 3.
The ATLAS , which is the latest version, is a 22 ring placido disc system 18 superiorly and 22 inferiorly that uses non-visible nm infrared light. The information obtained is from the reflection of the rings from the corneal surface. Therefore, the data obtained as such pertains only to the anterior corneal surface. The Visante 3. Additionally, the vertex of the cornea is recognized as the point with greatest signal in a vertical scan.
By using the corneal thickness map pachymetric data , with known anterior surface curvature data from the ATLAS, the posterior corneal curvature data may be calculated.
