Purpose: Present our early experience with the KAMRA (formerly AcuFocus) corneal inlay (AcuFocus, Inc. Irvine, CA) for the correction of presbyopia.

Methods: Exclusion criteria included moderate to high myopia, thin corneas, signs of cataract, peculiar corneal findings, or dry eye. Glasses are used preoperatively to simulate potential near and intermediate vision after inlay implantation. We explain that glasses may still be needed for dim lighting conditions, prolonged reading, and small print postoperatively. The inlay is placed under a flap on the stromal bed of the non-dominant eye.

Results: Patients prefer the KAMRA inlay to monovision as it does not sacrifice distance vision as much as in monovision in the implanted eye. 17 patients were implanted (6 myopic presbyopes and 11 plano presbyopes.) 3 patients had KAMRA implanted only, 10 had KAMRA and unilateral Lasik while the remaining 4 had KAMRA and Bilateral Lasik. Near Vision improved out to 1 month, at which time the majority of patient were N4 to N5 (J2-J3).

Conclusion: The KAMRA corneal inlay technology is an excellent option for presbyopia correction in patients without cataract. However, it is important to set patient expectations preoperatively.
