Tojo N, et al. - This research explored the variations of intraocular pressure (IOP) fluctuations before and after only ab interno trabeculectomy (AIT) or AIT with cataract surgery in pseudoexfoliation (PEX) patients, with the aid of the contact lens sensor Triggerfish. Fall in the IOP value and the IOP fluctuations to a greater extent with triple surgery than single surgery could be achieved in this study cohort.
