To retrospectively analyze the visual outcomes of KAMRA (AcuFocus Inc, Irvine, Calif.) inlay insertion in a cohort of patients reporting success of procedure, complications, patient satisfaction, and refractive outcomes.Retrospective trial at the TLC Laser Centre, Toronto.A total of 5 surgeons at the practice inserted 35 KAMRA inlays in 35 patients between October 2012 and June 2014. Some patients had a sole KAMRA inlay insertion, whereas others had combined laser vision correction (LVC) and KAMRA inlay on either the same day or sequentially. There was a small cohort of patients who had previous unrelated LVC. Mean time of follow-up was 299 days.After KAMRA inlay insertion there was a significant improvement in uncorrected near visual acuity (p = 0.00009), uncorrected intermediate visual acuity (p = 0.00006), and uncorrected distance visual acuity (p = 0.02), but levels of patient dissatisfaction were 43%. The most common cause for dissatisfaction was requirements for readers (23%), followed by dysphotopsias (11%). The explantation rate was 11.42%, and 28.5% of patients required enhancements after inlay insertion.The KAMRA corneal inlay has significant improvements in uncorrected near visual acuity, uncorrected intermediate visual acuity, and uncorrected distance visual acuity when used in isolation or combined with LVC. Appropriate patient selection is crucial. This procedure should not be used as first-line presbyopia management because of low levels of patient satisfaction, biocompatibility concerns, and explantation rates. |
