• Is refractive testing before and after cataract surgery necessary if you’re using a monofocal lens?


    Is pre- and post-refractive testing necessary for cataract surgery when you are using a standard Medicare-covered lens?


    Yes, the pre-tests are to check the health of the eye as well as taking the corneal measurements, which are used to calculate the lens implant power. The testing after surgery is for deciding on what glasses, if any, are needed after surgery.
