Real-world experience on intravitreal dexamethasone implant in patients with macular edema scheduled to undergo cataract surgery.

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
backgroundPatients with pre-existing macular edema (ME) due to diabetes and retinal vein occlusions (RVO) make up a growing population receiving cataract surgery. Surgery is associated with an increased risk of worsening existing ME due to post-surgical inflammation that can be further exacerbated by pre-existing diabetic retinopathy (DR) and retinal vein occlusion. This study aimed to examine the pre-operative use of intravitreal dexamethasone (DEX) implants in patients with ME undergoing cataract surgery.
methodsA retrospective study was conducted at National Cheng Kung University Hospital in Taiwan involving 19 eyes of 16 patients with DME or ME associated with RVO. All participants received a DEX implant at baseline and underwent phacoemulsification within 3 months after its insertion. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) and central subfield thickness (CST) were evaluated.
resultsDEX implants reduced the CST from baseline (357.8 μm) to pre-surgery (280.8 μm). This reduction below baseline continued to month 6 post-surgery (319.4 μm). From baseline (16.15 mmHg), the mean IOP initially increased pre-surgery (17.78 mmHg) before returning to the baseline value at month 6 post-surgery (16.15 mmHg). All patients improved their BCVA from logMAR 0.943 on average at baseline to logMAR 0.532 at month 6 post-surgery.
conclusionsThe results of the study suggested that patients with ME could benefit from DEX implants before cataract surgery within 3 months to achieve sufficient postoperative inflammation management and limit ME deterioration. DEX implants did not increase IOP post-surgery and was similar to baseline levels.
