To evaluate the improvement in visual acuity after KAMRA small-aperture intracorneal inlay implantation in post refractive and post cataract patients.
Shinagawa LASIK Center, Tokyo, Japan.
We performed a retrospective study of presbyopic patients who previously underwent inlay implantation after prior monofocal IOL implantation cataract surgery (n = 13), radial keratotomy, RK (n = 1) and phakic IOL (n = 3) surgeries. The inlay was implanted monocularly in the non-dominant eye of all 6 patients. Uncorrected distance visual acuity (UDVA), best-corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), and corrected near visual acuity (CNVA) were evaluated. The follow-up period was 3 months.
For the pseudophakic eyes, mean UNVA improved 5 lines. The Post-RK eye gained 2 lines of UNVA and the post-Phakic IOL eyes gained 3 lines. Mean UDVA, CDVA, CNVA for the pseudophakic and post-Phakic IOL remained stable and were 20/20, 20/16, J1 before and after KAMRA inlay surgery. UDVA decline 1 line, from 20/20 to 20/25, at 3 months post-op for the post-RK eye. CDVA and CNVA was 20/12 and J1 for the post RK eye pre- and post KAMRA inlay implantation.
These 3 months results indicate that implantation of a small aperture corneal inlay improves near acuity while maintaining distance acuity in presbyopic patients who have undergone prior cataract and refractive surgeries.
