I have a patient who currently wears a Varilux Comfort DRx with 8D base out OU. With her new script, the prism is now 13D base out OU. Our lab is telling us that that amount of prism is too high for a progressive. I am reluctant to put the patient in a FT28 because of her balance issues. Our lab is telling us that the best option for this patient is single vision. I know there has to be a lab out there with the expertise to be able to do her new script with the prism. Her distance Rx is very mild, but she does have 25D esotropia. Any help will be appreciated.
