Verisyse

Here is a case of a patient with a 6mm Verisyse place in her eye.  The images of the same eye is presented using the different technologies of Visante OCT (1310nm), Pentacam Scheimpflug (475nm), and the spectral domain Cirrus OCT (840nm).

Visante image of an eye with Verisyse Phakic IOL

In the Visante image (1310nm) of the eye with Verisyse, many of the software images shine.  The Visante is able to place an image of the lens inside the eye and very accurately predict the position of the lens post-op.  Read more on my other page about Verisyse Phakic IOL. In this enhanced anterior segment image a 16mm by 6mm image is produced that gives a full anterior segment image.  The Verisyse is clearly noted in the anterior chamber and the distanced of the lens to the endothelium is accurately measured.  The Vault distance -- the distance of the back side of the Verisyse and the crystalline lens is also measured.  The outlines of the ciliary body is clearly noted and useful if consideration is made for Visian ICL.

The Pentacam's Scheimpflug image of an eye with Verisyse

The above Pentacam's Scheimpflug image is the same eye as above.  In this case the IOL is optically neutral to the 475nm light and as a result it can not be "seen" by the Scheimpflug.  Although the enclavation site is noted as the irregular notch in the iris, the Verisyse is not visible.  There is no capability in providing post-operative status report.  The angle are not clearly visible and the ciliary body can not be outlined.

The Above two images of the same eye acquired by the Cirrus show the enclavation site on the left image and the top table of the PIOL on the right image.  The 840nm images have a difficult time with the relatively optically neutral PIOL.  The spectral domain provides excellent detail but the image is only 2 by 3mm in size!  as such much of the valuable data in post-operative safety outcome can not be measured using this technology.
