Corneal topographic changes after upper eyelid blepharoplasty prior to cataract surgery.
Article in International ophthalmology, 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
purposeTo investigate the effect of upper eyelid blepharoplasty (UEB) on corneal topography in cataract patients using Scheimpflug technology.
methodsThis prospective single-center, longitudinal study included 88 eyes of 45 patients undergoing UEB for dermatochalasis prior to cataract surgery. Scheimpflug imaging (Pentacam®AXL, Wetzlar), was performed preoperatively and at two weeks and three months postoperatively. The primary outcome was change in corneal astigmatism, assessed as the cylindrical component of total corneal refractive power (TCRP). Secondary outcomes included K1, K2, Kmax, Km, astigmatism axis and anterior chamber depth (ACD), front and back Keratometry (FK, BK).
resultsThe mean age of 67.0 ± 8.7 years; 67% of patients were female (n = 30) and 33% male (n = 15). At three-months, statistically significant changes were observed in cylindrical TCRP (P = 0.010), K1 (P = 0.023), and ACD (P = 0.007). Additionally, FK2 showed a statistically significant change at 2 weeks (P = 0.021) but not at three-months. F-KMax and BKm were not significantly changed at 2 weeks, but showed statistically significant changes at three-months follow-up (P = 0.043 and P = 0.010 respectively).
conclusionUEB was associated with minor changes in selected corneal topographic parameters and ACD. Although some changes reached statistical significance, their clinical relevance was not established. Repeat corneal measurements after UEB may be considered before cataract or refractive surgery when precise refractive outcomes are intended. These findings do not establish a specific three-month waiting period or demonstrate an effect on intraocular lens (IOL) power calculations or final refractive outcomes.
