Abstract Details


To evaluate the visual outcomes after KAMRA corneal inlay (Acufocus, Inc., Irvine, CA) implantation in both phakic and pseudophakic patients.


Department of Ophthalmology, Saarland University Medical Center, Homburg, Germany. Experimental Ophthalmology, Saarland University, Homburg, Germany.


Twenty patients between 47 and 63 years old were divided into two groups: Group 1 (13 phakic patients) and Group 2 (7 pseudophakic patients). Group 1 underwent simultaneous LASIK and KAMRA corneal inlay implantation in the nondominant eye of hyperopic and emmetropic presbyopic patients. Group 2 underwent cataract surgey or refractive lens exchange with monofocal intraocular lens (IOL) implantation and 6 weeks later KAMRA corneal inlay implantation in the nondominant eye. The monocular uncorrected distance (UDVA), intermediate (UIVA), near visual acuities (UNVA), and a subjective patient questionnaire on satisfaction were compared pre- and postoperative between the 2 groups.


All twenty patients were available for the 6-month postoperative examination. Both groups achieved a mean UDVA of 20/20, with Group 1 and Group 2 gaining 3 lines and 6 lines respectively. The mean UIVA in Group 1 was J2 with 8 lines gained and in Group 2 was J1 with 8 lines gained. The mean UNVA was J2 with 6 lines gained in Group 1 and J1 with 7 lines gained in Group 2. Twelve patients (92%) in Group 1 and 7 patients (100%) in Group 2 reported being very satisfied.


Implantation of the KAMRA corneal inlay improved monocular uncorrected near, intermediate and distance visual acuities in both groups. Although the outcomes were comparable between the groups, Group 2 had the highest patient satisfaction. The KAMRA corneal inlay seems to be an effective and safe method for presbyopia correction in both phakic and pseudophakic eyes.
