Abstract Details


To evaluate the outcomes of implanting a small aperture corneal inlay with simultaneous LASIK surgery for the treatment of presbyopic patients with refractive errors.


Shinagawa LASIK Center, Tokyo, Japan


From August 2009 to February 2011, a total of 1,175 patients received simultaneous LASIK along with KAMRA inlay (AcuFocus, USA) implantation. For all patients, a 200-micron flap was created using a femtosecond laser after which an excimer laser ablation was performed and a corneal inlay implanted. The corneal inlay was implanted monocularly in their non-dominant eye. The fellow eye was corrected for distance. The mean uncorrected distance visual acuity (UDVA) was 20/125 and the mean uncorrected near visual acuity (UNVA) was J6 preoperatively. Postoperative visual outcomes and patient satisfaction were evaluated.


At the 1-year postoperative exam, all patients were available for evaluation. Mean UNVA improved significantly from preoperative J6 to postoperative J2 (P<0.0001), a mean gain of 3 lines. The mean UDVA improved significantly from preoperative 20/125 to 20/20 (P<0.0001), a gain of 8 lines. The patientsÂ’ satisfaction was high and their dependency on reading glasses was reduced.


In this high-volume study of simultaneous LASIK surgery along with inlay implantation, 1 year outcomes demonstrate improvements in both distance and near visual acuity, high patient satisfaction, and a reduced dependency on reading glasses. Further, these results show that this surgery is an effective treatment for presbyopic patients with refractive errors.
