By mapping your corneal shape with a diagnostic technology called corneal topography, we can calculate the amount of astigmatism correction that your eye should require in eyeglasses following cataract surgery.We can then incorporate this amount of astigmatism correction into the artificial lens that is selected for your cataract surgery.When exercising their judgement, healthcare professionals are expected to take this guidance fully into account.However, the guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or guardian or carer.While lens replacement surgery technically does not have FDA approval, some eye surgeons will perform the procedure off label in certain circumstances.This is legal and sometimes is the most effective way to correct particular vision problems.
