KUALA LUMPUR, Malaysia — Patients who underwent conductive keratoplasty with a modified technique reported a higher level of satisfaction than patients who underwent conventional CK, according to a speaker here.

Low Cze Hong, MD, FACS, FRCS, FRCOphth, performed “light touch” CK in 85 eyes of 65 patients under local anesthesia using the Refractec ViewPoint CK system. He presented his results here at the Asia Pacific Academy of Ophthalmology meeting. Dr. Low compared the results with the light touch procedure against the results of the clinical study submitted to the Food and Drug Administration for approval of conventional CK, he said.

Dr. Low performed the modified technique in one eye of 45 patients and bilaterally in 20 patients. All patients were between 43 and 59 years old, he said. There was no loss of best corrected visual acuity for any of his patients, and 99% achieved N6 or better near vision, he said.

“Patients who undergo [light touch] CK find the response is greater because it’s less invasive and results are enhanced,” Dr. Low said.

Dr. Low sees CK as an additional tool for presbyopia correction because “it’s suitable to those averse to cutting a corneal flap and its associated risks.”

Counseling to ensure than patients have reasonable expectations is a necessary first step before surgery, he told attendees.

“We’re not promising the sky, and it’s very important in presbyopia,” Dr. Low said. “As an initial start, anyone who embarks on a refractive procedure needs to lower expectations. The important thing is realistic expectations. Aim for J1, but tell your patients they’ll achieve J3,” and you will have a happy patient, he said.

The light touch CK technique was also recently discussed at The Cole Eye Institute’s Cornea and Refractive Surgery Summit.
