Refractive surgery

There are many different types of refractive surgery, and the doctors and staff at Helena Vision Center have the knowledge and experience to help each individual choose the appropriate one for his or her visual needs.

LASIK: In laser-assisted in-situ keratomileusis, a flap of surface tissue is created, exposing the underlying corneal tissue. A laser is used to reshape this tissue, then the flap is laid back down in order for the cornea to heal.

Photorefractive keratectomy: Instead of creating a flap of tissue as with LASIK, for PRK, the surgeon gently brushes aside a layer of surface cells, and then guides a laser to reshape the underlying tissue. A protective contact lens is placed over the treated area, allowing the cells to regenerate and heal.

Refractive lens exchange: This procedure involves removing the eye’s natural lens and implanting an artifical lens that is selected to correct the patient’s prescription. RLE is essentially the same technique as cataract surgery, the only difference being that the natural lens is not clouded.

Implantable contact lenses: ICL’s are placed in front of the pupil and attach to the iris. The surgical procedure involves creating a tiny incision in the cornea and properly positioning the contact lens.
