Abstract

PURPOSE: To analyze the dynamics of telemetrically measured intraocular pressure (IOP) during the first year after implantation of a Boston keratoprosthesis type I (BI-KPro) cornea and to compare agreement of telemetric IOP measurements with finger palpations. DESIGN: Prospective, open-label, multicenter, single-arm clinical trial. METHODS: In the ARGOS (NCT02945176) study, 12 individuals underwent implantation of an Eyemate-IO intraocular system. Follow-up after surgery took place 12 months later with 13 visits planned per patient. During BI-KPro surgery, an electromagnetic induction sensor ring enabling telemetric IOP data transfer to a hand-held reading device outside the eye was implanted into the ciliary sulcus with or without trans-scleral suture fixation. Comprehensive ophthalmic examinations and IOP assessments through the telemetric system were compared to IOP assessed by finger palpation by 2 experts. RESULTS: Preoperative IOP measured by Goldmann tonometry was 13.4 +/- 6.2 mm Hg. Telemetric IOP peaked at 23.1 +/- 16.5 mm Hg at the first postoperative day. On day 5, mean IOP was 16.0 +/- 5.2 mm Hg and 20.95 +/- 6.5 mm Hg after 6-12 months. IOP estimation by finger palpation was grouped in 4 categories: normal, A; soft/hypotonic, B; borderline, C; and hypertonic, D. Mean telemetric IOP was 18.2 +/- 6.1 mm Hg in category A, 8.9 +/- 2.8 mm Hg in B, 22.4 +/- 4.9 mm Hg in C, and 34.3 +/- 11.0 mm Hg in D. Differences in mean telemetric IOPs per category were statistically significant (P < .001). Daily IOP fluctuations and peaks could be identified. CONCLUSIONS: Telemetric IOP assessment seems to be able to identify postoperative IOP peaks and a longitudinal increase of IOP after BI-KPro surgery. IOP measurements using the telemetric Eyemate-IO sensor showed a satisfactory agreement with those of finger palpations by 2 experts. (C) 2019 Elsevier Inc. All rights reserved.
