Laser iridotomy is a surgery that's used to prevent or control glaucoma. An ophthalmologist uses a laser to make a tiny hole in the iris (colored part) of the eye. This opening - usually the size of a pinhead - allows fluid to flow from behind the iris and out through the drainage angle.

With posterior capsulotomy, converging laser beams are aimed directly at the hazy lens capsule, and as they meet they cut a small hole in the capsule. This allows light to pass through again, restoring your vision to the way it was not long after your cataract surgery. Learn more at http://www.geteyesmart.org.

Like your eye's natural lens, an IOL helps you see by focusing the light that comes through the cornea and pupil, focusing the light onto the retina. The retina converts the light rays into signals that are sent through the optic nerve to the brain, where they are interpreted as the images we see. Learn more at http://www.geteyesmart.org.
