Sunrise Technologies has developed laser thermal Keratoplasty (LTK). This procedure was FDA approved on June 30, 2000 for the temporary reduction of hyperopia from +0.75 to +2.50 diopters for patients 40 years and older with up to 0.75 diopters of astigmatism and refractive stability for the previous 6 months. Unlike most refractive surgery, LTK is not performed in an operating suite but in an ordinary exam room. It involves the strategic placement of 16 laser spots onto the peripheral cornea. In LTK, the eye is numbed with anesthetic drops and held open with an eyelid holder. The tear film is allowed to dry for 3 minutes before the laser is applied. The laser application itself takes less than 3 seconds per eye. The treatment thermally contracts the tissue, causing the central cornea to steepen. A bandage soft contact lens is usually placed on the eye until the following day. They eye may have some irritation for the first few days.

An important note from Dr. Thompson:

See: Risks of Refractive Surgery. Remember surgery is surgery and all surgery has risks. This is not meant to discourage you but these are facts you should know if you plan to have surgery preformed. This office is extensively involved in refractive surgery and would be happy to meet with you and discuss your case. I have personally had refractive surgery. But, just because these risks were acceptable to me does not mean they will be acceptable to you. I strongly recommend you educate yourself prior to surgery and then consult a knowledgeable eye care provider to further guide you through the procedure and follow-up. Pre and post operative care is critical in maximizing your chance of a good outcome.

Our office policy is to educate our refractive surgery patients well enough that they have realistic expectations and know the risks before they commit to the surgery, we believe in informed consent. Once the decision is made, it is our goal to get that person to the best surgeon for the amount of money they want to spend.
