Because LASIK is performed under
a layer of protective tissue, there is less
surface area to heal, less risk of corneal haze,
less postoperative discomfort, and less need for
postoperative medication. Your vision also
returns more rapidly- often within a day or so.
  Surface Laser Treatment: PRK
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. |
