To evaluate early postoperative safety and efficacy outcomes after monocular Kamra corneal inlay (acufocus – ACI 7000) implantation in presbyopic patients.

In this interventional study, 42 Patients between 45 and 60 years old, who met the criteria for undergoing small-aperture corneal inlay implantation were selected and the karma was implanted in the nondominant eye with assistance of femtosecond laser. Contrast sensitivity and visual field was assessed preoperatively and 6 months postoperatively. The UDVA and near visual acuity (UNVA) were assessed preoperatively, 1 week, and 1, 3 and 6 months postoperatively. The minimum postoperative follow-up was 6 months.

The mean binocular UNVA improved from 20/80 (j9) to 20/32 (j3) (P<.001) ; 33 patients (78%) had a UNVA of 20/32 or better. The mean UDVA was 20/32 in the surgical eye and 20/25 binocularly after 6 months. Photopic and mesopic contrast sensitivity remained in the normal range (P<.001). No patient had detectable central visual field defect. No inlay was explanted. No corneal melting and no hyperopic shift were observed.

Based on the 6 months follow up,the corneal inlay implanted in femtosecond laser-created flaps and pockets, was effective and safe for the corneal compensation of presbyopia improved near visual acuity with minimal impact on UDVA or contrast sensitivity in the implanted eye.
