For the iPhone and Mac
We are porting our most popular software into the iPhone.  The mobile computing platform is allowing eye care professionals to offer more precise care.  A Mac version will follow later.  Check back to this page for updates when it is available
                                                                                   
iRx (in development)

iRx will combine the abilities of X-Cyl and ImageRx into one application with additional calculations involving vertex distance changes for lens design and a feature to help isolate paretic muscles from the Parks - Bielschowsky 3-way head tilt test for hyperdeviated eyes.  This application will be available through iTunes.

For the PC

X-CYL

Toric Crossed-Cylinder Calculator

X-Cyl is a utility that assists in tough contact lens fitting challenges.  Toric contact lenses can correct for astigmatism.  Sometimes however unexpected results occur during this fitting process.  Unexpected residual refractive errors (overrefractions) can occur than what is clinically predicted from traditional contact lens fitting technique.  When this occurs your eye doctor has to perform a very difficult mathematical calculation to correct for this issue.  The mathematical calculation is difficult and can easily result in an error.  X-Cyl does the math for the physician.  The program even can correct for unwanted contact lens rotation in mathematical calculations.

Updated in 2009 to run on 64 bit operating systems, offer more tips for users and run by itself without an additional runtime DLL file.

ImageRx

Aniseikonic Lens Design Calculator

ImageRx is a wonderful utility that greatly eases the design of Aniseikonic lenses.  Some prescriptions create unwanted magnification difficulties between the two eyes.  The brain can not efficiently combine two unequal sized images on the retina.

ImageRx allows doctors to manipulate many variables to tweak lens parameters to either minimize the image size difference.  Without this software, doctors would have to use nomograms (charts) or manually manipulate a complex equation to solve for each variable.  Our program performs the difficult mathematic calculations to allow optometric physicians to more creatively design tough eyewear prescriptions.

Click on the icon to download ImageRx.

ImageRX and X-Cyl are very small programs with efficient code to calculate mentally tough equations.  The programs can be installed anywhere on your PC.  Double clicking on the program opens it so there really is not installation required.  You may wish to create a shortcut to place the programs on your desktop.
