Clinical and surgical outcomes of tectonic corneal patch grafts : insights from a tertiary referral hospital.
Article in BMC ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThis study aimed to report the clinical characteristics, surgical indications, outcomes and long-term complications of full-thickness or lamellar corneal patch grafts for various indications. MATERIAL-
methodThis retrospective study included 48 eyes of 47 patients who underwent full-thickness or lamellar corneal patch keratoplasty for treatment of corneal perforation, melting and descemetocele. Patient demographics, preoperative features, best-corrected visual acuity before and after surgery, mean follow-up time, corneal graft type, long-term complications, need for additional surgery, and anatomical success were analyzed.
resultsOf the 48 eyes, 21 had corneal perforation, 21 had severe corneal melting, and six had descemetocele. Sjögren's syndrome (eight eyes, 16.7%), trauma (eight eyes, 16.7%), and limbal stem cell deficiency (eight eyes, 16.7%) were the most common indications for corneal patch grafting. The most common complications after surgery were graft melting (11 eyes, 22.9%) and glaucoma (5 eyes, 10.4%). One eye developed phthisis bulbi. Penetrating keratoplasty was performed in 8 of the 11 eyes with recurrent graft melting. All descemetocele cases were central and corneal melts were more frequently located paracentrally (p = 0.0001). Anatomical success was achieved in 39 eyes (81.2%).
conclusionCorneal patch grafting is a safe and effective method for maintaining ocular integrity in corneal melting and perforation that can not be closed using conventional methods. With a success rate of over 80%, corneal patch grafts can delay a larger full-thickness graft, especially in eyes with acute inflammation, until systemic therapy is effective.
