Robotic Assisted-Intravitreous Light Pipe Illumination for Cataract Surgery in Eyes with Corneal Opacity: Case Reports.
Article in Case reports in ophthalmology. 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
Introduction: In cataract surgery for eyes with corneal opacity, reduced intraoperative visibility remains a major surgical challenge. To enhance intraoperative visualization, OQrimo, a robotic medical device approved in Japan, was used to hold a light guide. Outcomes of 3 eyes from 2 cases are reported. Case Presentation: Case 1: A 48-year-old man developed bilateral corneal opacity from graft-versus-host disease following umbilical cord blood transplantation for acute myeloid leukemia. At age 45, he underwent penetrating keratoplasty in the right eye but declined surgery in the left eye. Bilateral cataract surgery under general anesthesia was performed. Due to poor visibility under the surgical microscope in both eyes, a 25-gauge light pipe was inserted into the vitreous cavity and stabilized using OQrimo, thereby improving intraoperative visibility and enabling successful cataract surgery in both eyes. Case 2: A 74-year-old man had previously undergone pterygium excision with conjunctival autograft transplantation for a lesion involving the pupillary area of the left eye. Residual central corneal opacity remained, and cataract surgery was performed 6 months later. Due to poor microscopic visibility, a 25-gauge light pipe was inserted into the vitreous cavity and held using OQrimo. While visualization improved, the weight of the OQrimo arm caused ocular deviation, preventing stable positioning and necessitating its discontinuation. Conclusions: OQrimo effectively enhanced intraoperative visibility in cataract surgery for eyes with corneal opacity, although stable positioning was occasionally challenging.
