Long-Term Astigmatism after Intraocular Pressure Sensor Implantation and Nonpenetrating Glaucoma Surgery - EYEMATE-SC Trial.

PURPOSE: To investigate the long-term astigmatism after combined non-penetrating glaucoma surgery (NPGS) and implantation of the first miniaturized suprachoroidal intraocular pressure (IOP) sensor EYEMATE-SC. SETTING: The study was conducted in five medical centers in two different countries. DESIGN: Retrospective multicenter clinical study. METHODS: Astigmatism of patients instrumented with the EYEMATE-SC IOP sensor was assessed over a follow-up period of three years. Refraction and corrected distance visual acuity (CDVA) were obtained preoperatively, after 6 months, 1, 2, and 3 years. A canaloplasty-operated patient cohort served as control. Astigmatism was evaluated using 3-dimensional power vector analysis involving the spherical equivalent M, and the Jackson crossed cylinder projections J0 and J45. Exclusion criteria included neovascular and angle-closure glaucoma, myopia, axial length outside 22 to 26 mm, other ocular diseases, prior glaucoma surgery, other ocular surgery within 6 months (cataract surgery within 3 months) prior to NPGS, serious generalized conditions, and other active medical head/neck implants. RESULTS: Multivariate analysis indicated no changes in astigmatism along the observation period in both the EYEMATE-SC (n = 24) and the canaloplasty (n = 24) group (P > 0.05 or nonsignificant after Bonferroni correction). Astigmatism was unchanged between the EYEMATE-SC and the canaloplasty group at all time points (P > 0.05). CDVA didn't change along the observation period of three years in each of both groups (P > 0.05). CONCLUSIONS: Despite its suprachoroidal localization, the present study indicates that the miniaturized EYEMATE-SC IOP sensor doesn't negatively affect the long-term astigmatism after combined implantation with NPGS.

The electronic medical record in multi-site family practice, Part 1: The planning phase.

Electronic medical records (EMRs) are being successfully implemented on a regular basis. They provide real benefits. This article presents a detailed explanation of how this medical group implemented and created a paperless medical practice environment and an electronic medical record. This includes an explanation of hardware and software components, the method of creating the EMR, benefits, pitfalls, and effect on the practices.
