title: One-year visual outcomes and patient satisfaction after surgical correction of presbyopia with an intracorneal inlay of a new design.
abstract: OBJECTIVE
  To evaluate the safety and efficacy of the third-generation Kamra corneal inlay (ACI 7000PDT) implanted monocularly in corneal pockets of emmetropic presbyopic patients to improve near and intermediate vision.
  
  
  METHODS
  University Eye Clinic, Paracelsus Medical University, Salzburg, Austria.
  
  
  METHODS
  Cohort study.
  
  
  METHODS
  The corneal inlay was implanted in the nondominant eye over the line of sight by creating a corneal pocket with a femtosecond laser. The minimum postoperative follow-up was 12 months. Distance, intermediate, and near visual acuities were assessed over the follow-up. Other examinations included slitlamp evaluation, central keratometry, computerized corneal topography, endothelial cell count, and central corneal thickness. Patients completed satisfaction questionnaires preoperatively and 3, 6, and 12 months postoperatively.
  
  
  RESULTS
  The study evaluated 24 patients. After a mean follow-up of 12 months, 92% of patients read Jaeger (J) 3 or better with the surgical eye, the mean binocular uncorrected near visual acuity improved from J5 preoperatively to J2, and the mean binocular uncorrected intermediate visual acuity was 20/20 (67% ≥ 20/20). At 12 months, the mean uncorrected distance visual acuity was 20/20 in the surgical eye and 20/16 binocularly. Patients reported no change in distance vision, and their need for reading glasses decreased significantly (P<.001). No inlay was explanted and or recentered during the reported follow-up.
  
  
  CONCLUSIONS
  The new corneal inlay was a safe and effective treatment for presbyopia over a 1-year follow-up.
