Hello, I received a Technis lens implant last Friday, and when I returned for a follow up visit on Wednesday, I complained that my vision was not distinct and defined as I had been told it would be, that in fact my vision was not as good as it had been before with contacts or glasses. My doctor then told me I would have to have YAG 3 months later to remove a membrane, and that this was required in 100% of Technis lens implants. I had never been told this before and it was not in the material I received before the surgery, and I have been unable to find corroboration of this online. Does anyone have knowledge about this, thanks.
