Salvaging a Failed PreserFlo MicroShunt Using a Telescopic Tube-in-Tube Connection Technique With an EyePlate Implant: A Case Report.
Article in Clinical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The PreserFlo MicroShunt is a subconjunctival glaucoma drainage device designed to reduce intraocular pressure (IOP) via a minimally invasive approach. However, device failure due to bleb fibrosis remains a significant clinical challenge, especially when initial revision surgery is unsuccessful. We present a 75-year-old male with pseudoexfoliation glaucoma who previously underwent PreserFlo MicroShunt implantation and a subsequent revision procedure at an outside institution. Due to persistently elevated IOP and progressive visual decline, he was referred to our center for further management. A novel telescopic tube-to-tube connection was performed between the existing PreserFlo MicroShunt and a new EyePlate-200 implant, utilizing and preserving the original scleral tunnel. Postoperative IOP decreased from 40 to 10 mmHg and remained stable without complications during a 6-month follow-up. A surgical video is provided as Video 1. This case illustrates a novel telescopic tube-to-tube connection technique to restore aqueous outflow in cases of PreserFlo MicroShunt failure. By preserving the original scleral tunnel, this approach may offer a minimally invasive alternative to complete device explantation or conventional tube shunt surgery.
