PRAGUE — Long-term, 4-year results demonstrated a corneal inlay to be a safe and effective treatment for presbyopia, according to a surgeon speaking here.

The Kamra intracorneal inlay (AcuFocus) is an opaque ring that is implanted in the non-dominant eye. The small central aperture exploits the pinhole effect to increase depth of focus.

"The inlay is implanted under a LASIK flap. We now use the femtosecond laser to create a flap at 170-µm depth," Wolfgang Riha, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.

Salzburg University, where Dr. Riha works, is one of the European centers participating in the U.S. Food and Drug Administration trial for the Kamra implant.

"In the 32 patients treated in our center, near vision improved from J7/J8 at baseline to J2 at 4 years, and intermediate vision from 20/40 to 20/25. Distance vision decreased about one line. While before surgery 88% of the patients needed reading glasses, only 6% were dependent on them after surgery," Dr. Riha said.

OQAS (Visiometrics) analysis showed improved optical quality within the whole accommodative range in the implanted eye compared to the non-implanted eye.
