PRK, or Photo-refractive keratectomy, treats refractive errors by removing tissue from the surface of the cornea. Our surgeons may recommend this if the shape or thickness of your cornea meets certain criteria.
Before the procedure, your eye is numbed using "eye drop" anesthesia and an instrument is placed between the eyelids to prevent blinking. Your surgeon, using a laser, removes the proper amount of tissue and reshapes the cornea's surface. By altering the shape or placement of the laser beam, the cornea is made flatter to treat nearsightedness, steeper to treat farsightedness, and/ or more rounded to treat astigmatism. You will wear a bandage contact lens for three to five days after the surgery. Your surgeon may recommend treating one eye at a time because recovery with this surgery may take longer.
Modern advances in cataract surgery allow many patients to see well after surgery without glasses. Modern lens implants can correct farsightedness and nearsightedness quite well.
To fix astigmatism, or irregular shape, our
surgeons can place precise incisions in the
cornea to improve vision. These incisions are
made under local anesthesia, so you feel no
pain. After the procedure, the eye can feel
scratchy for a few days.
These incisions can be performed at the same time as your cataract surgery. If you have already had cataract surgery, these treatments can be performed in our procedure suite.
