Color-Contrast Adjustment With a 3D Head-Up System to Aid Capsulorhexis After ICG Staining: Single-Patient Case Report From a Tertiary Center.
Article in Case reports in ophthalmological medicine, 2026. 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
We report a single case in which continuous curvilinear capsulorhexis (CCC) was safely completed using NGENUITY in 3D head-up surgery (HUS) during cataract surgery. Visibility of the dye-stained anterior capsule was improved during the CCC procedure. An 84-year-old female underwent a planned extracapsular extraction on December 2022, in HUS using NGENUITY for a Grade 4 cataract classified by the Emery-Little classification. After staining the anterior capsule with 0.5% indocyanine green (ICG) for 5 s, the anterior chamber was washed to reduce the risk of endothelial damage. Then, CCC was performed by adding red enhancement to a monochrome-filtered image using the color contrast adjustment function of NGENUITY. The contrast of the anterior capsulotomy margin appeared sharper than in the normal setting, which enhanced the visibility of the capsulotomy margin of the anterior lens capsule. This allowed CCC to be completed smoothly and safely. Subsequently, the surgery was performed as usual and the intraocular lens (IOL) was fixed in the capsular bag to complete the procedure. One month after surgery, the fixation and position of the IOL were stable. Color channel adjustment in a 3D head-up system improved the visibility of CCC margins after ICG staining in advanced nuclear cataracts. This technique may be useful in cases with a poor red reflex. Future prospective studies using objective contrast evaluation are needed.
