  • femtosecond laser assisted small aperture corneal inlay implantation for corneal compensation of presbyopia two year follow up
    Journal of Cataract and Refractive Surgery, 2013
    Co-Authors: Orang Seyeddain, Wolfgang Riha, Theresa Ruckl, Alexander Bachernegg, Herbert A Reitsamer, Gunther Grabner, Alois K Dexl
    Abstract:

    PURPOSE: To report the 2-year postoperative safety and efficacy outcomes after monocular Kamra corneal inlay (ACI7000PDT) implantation in femtosecond laser-created corneal pockets of emmetropic presbyopic patients to improve near and intermediate vision. SETTING: University Eye Clinic, Paracelsus Medical University, Salzburg, Austria. DESIGN: Prospective interventional case series. METHODS: Patients had corneal inlay implantation in the nondominant eye. Emmetropic presbyopic patients between 45 and 60 years old with an uncorrected distance visual acuity (UDVA) of 20/20 or better in both eyes and without additional ocular pathology were eligible. Contrast sensitivity, visual field examinations, endothelial cell count (ECC), and central corneal thickness (CCT) measurements were assessed preoperatively and 12 and 24 months postoperatively. The UDVA, uncorrected intermediate visual acuity (UIVA), and near visual acuity (UNVA) were assessed preoperatively and 1 day, 1 week, and 1, 3, 6, 9, 12, 18, and 24 months postoperatively. The minimum postoperative follow-up was 24 months. RESULTS: After 24 months, the mean binocular UNVA improved from 20/50 to 20/25; 20 patients (83%) had a UNVA of 20/25 or better. The mean binocular UIVA was 20/20. The mean UDVA was 20/20 in the surgical eye and 20/16 binocularly after 24 months. Contrast sensitivity under photopic and mesopic conditions remained in the range of the normal population. No patient had detectable central visual field defect. No inlay was explanted. No inflammatory reactions were observed. The ECC and CCT remained stable. CONCLUSION: The corneal inlay implanted in femtosecond laser-created pockets was effective and safe for the corneal compensation of presbyopia in emmetropic patients after 24 months. FINANCIAL DISCLOSURE: Acufocus Inc., Irvine, California, USA, financially supports the Research Foundation for Promoting Ophthalmology, Salzburg, Austria, as the clinical research center of the University Eye Clinic (Paracelsus Medical University).

  • small aperture corneal inlay for the correction of presbyopia 3 year follow up
    Journal of Cataract and Refractive Surgery, 2012
    Co-Authors: Orang Seyeddain, Wolfgang Riha, Theresa Ruckl, Melchior Hohensinn, Gunther Grabner, Alois K Dexl
    Abstract:

    Purpose To report the 3-year postoperative safety and efficacy outcomes of the Acufocus corneal inlay. Setting University Eye Clinic, Paracelsus Medical University, Salzburg, Austria. Design Prospective nonrandomized noncomparative cohort study. Methods The corneal inlay was implanted in the nondominant eye of naturally emmetropic presbyopic patients. Refraction, uncorrected near (UNVA), intermediate (UIVA), and distance (UDVA) visual acuities; corrected distance visual acuity (CDVA); contrast sensitivity; visual fields; subjective patient satisfaction and symptoms; and operative and postoperative adverse events and complications were evaluated. Results The study enrolled 32 patients. The mean UNVA improved from Jaeger (J) 6 preoperatively to J1 at 3 years and the mean UIVA, from 20/40 to 20/25, respectively. At 3 years, 97% of eyes had a UNVA of J3 or better and 91% had a UIVA of 20/32 or better. The mean UDVA was 20/20, with all eyes achieving 20/32 or better. Nine eyes (28.3%) lost 1 line of CDVA, 1 eye (3.1%) lost more than 2 lines (3.8 lines), and 3 eyes (9.3%) gained 1 line. No inlay was explanted, and no inflammatory reactions were observed. At 3 years, 15.6% of patients reported severe night-vision problems and 6.3% (versus 87.5% preoperatively) reported being dependent on reading glasses. Conclusions These 3-year results support the safety and efficacy of the corneal inlay to correct presbyopia in naturally emmetropic presbyopic patients. However, despite a significant gain in UNVA and UIVA, 28.3% of patients lost 1 line of CDVA.
