--CK is a safe, minimally invasive procedure.
--CK is fast: Like LASIK, the procedure is performed in a few minutes.
--CK is convenient and comfortable: It is performed in-office with only topical anesthesia.
--CK does not involve the cutting or removal of tissue therefore it meets the needs of patients who are more risk-adverse.
--CK is the first alternative to laser for hyperopia.
How CK SM Works:
CK is the first alternative to laser for hyperopia (farsightedness). Research into treating hyperopia has discovered that the application of heat energy to the cornea can cause a shrinking of the corneal tissue (thermokeratoplasty). This shrinkage can treat hyperopia by steepening the surface of the cornea. CK builds upon the principles of thermokeratoplasty, using radiofrequency (RF) energy to reshape the cornea and adjust its refractive characteristics. More than 20 years of research into this technique have established the depth and temperature necessary to achieve refractive change.
The physician uses a small probe, thinner than a strand of human hair, which releases (RF) energy. The probe is applied in a circular pattern on the outer cornea to shrink small areas of corneal tissue. This circular shrinkage pattern creates a constrictive band (like the tightening of a belt), increasing the overall curvature of the cornea. The procedure, which takes less than three minutes, is done in-office with only topical anesthesia (eye drops).
CK From the Patient's Perspective:
Once the ophthalmologist has determined the patient to be a candidate for CK, the patient's cornea will be mapped with a computer to evaluate its curvature (refractive characteristics).
After applying drops to numb the eye and ensure the procedure is painless, the doctor imprints a treatment pattern on the cornea using rinse-away dye. The pattern guides the doctor's treatment; each point represents a place where radiofrequency (RF) energy will be applied. Once the cornea is marked, the doctor uses a small probe, called a Keratoplast™ Tip, to apply the energy in a circular pattern to reshape the cornea. The most common sensation that patients experience is a feeling of pressure on the eye.
The doctor will apply antibiotic drops that the patient will continue using for three days, as per labeling. The patient may need to wear dark glasses after the CK treatment and use artificial tears for up to one week. As with other vision procedures, there may be some mild discomfort and light sensitivity for a few days, and many patients experience a foreign-object sensation or a slight "scratchiness" in the eye. This usually subsides within 24 hours of the procedure.
CK Patient Profile:
Following are the basic criteria in order to be considered a candidate for CK:
--Age 40 and over
--No drastic changes in vision or eyeglass prescription within the past year
--No eye conditions such as glaucoma, severe dryness, keratoconus, herpes of the eye, aggressive keloid formation or corneal dystrophy
--No physical conditions such as diabetes, pregnancy or nursing, and vascular or autoimmune diseases

CK in Montgomery:
John Swan, M.D., corneal and refractive surgeon at Montgomery Eye Physicians (MEP), is the first surgeon to bring this technology to Montgomery. Dr. Swan performs CK on an outpatient basis at the MEP-Sturbridge office. In preparation for CK, candidates must undergo a pre-operative evaluation with the Refractive Team.
