LTK (Laser Thermal Keratoplasty)

In LTK, the doctor uses a laser to heat a series of small, dot-shaped areas of the cornea. This causes the corneal tissue to expand and the curvature of the cornea steepens. LTK is used to treat people suffering from hyperopia (farsightedness). Candidates for LTK should be at least 40 years old, have stable vision and no abnormalities of the cornea or external eye.

Some 30% of the patients treated with LTK have retained functional near vision in the correction of presbyopia as well. The procedure takes approximately 2.8 seconds per eye and the effect is immediate. Recent FDA monitored studies have indicated an 84% success rate in restoring 20/40 or better vision in hyperopic patients. To date, no complications or adverse events have been reported. One hundred percent of the patients treated to date have met the FDA criteria for stability. Sunrise Technologies has recently received FDA clearance to treat both eyes on the same day. Sunrise has also begun a study of hyperopia treatment of up to 4 diopters as well as patients who are overcorrected from myopic PRK procedures.
