Presbyopia appears when a muscle that allows the lens to change its shape and size stops working. Thanks to this lens movement we are able to focus the images from near and far. When the muscle in question stops working we can not focus the images correctly. There are only two alternatives: the continued use of glasses that we must continually change degrees, or surgery, which will definitively solve the problem.
The intervention lasts about 10 minutes per eye and involves replacing the lens with an intraocular lens that allows us to focus at different distances.
The recovery is very fast and the next day the patient is able to see normally and with hardly any discomfort.
