Effect of upper eyelid blepharoplasty with or without orbicularis oculi muscle removal on anterior segment parameters, keratometry, and ocular biometry.
Trial report in International ophthalmology, 2024. 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 evaluate the effect of upper eyelid blepharoplasty with or without the removal of a strip of orbicularis oculi muscle on corneal topographic parameters, anterior segment parameters, intraocular pressure, and ocular biometry.
methodThis prospective study examined 428 eyes of 214 patients with dermatochalasis. Patients were divided into two groups randomly: those who underwent orbicularis oculi muscle excision (Group 1) during blepharoplasty and those who did not (Group 2). Following a detailed ophthalmological examination, corneal topography was used to evaluate the eyes anterior chamber depth (ACD), iridocorneal angle (ICA), keratometry measurements, and corneal astigmatism (CA) in the preoperative and postoperative first and third months. Ocular biometry was used to assess axial length (AXL) and intraocular lens (IOL) power. Goldmann applanation tonometry was used to measure intraocular pressure (IOP).
resultsThe age and gender distribution between the groups were similar (p = 0.595 and p = 0.493, respectively). In Group 1, the mean steep keratometry (K2) value increased by 1.1 D and the mean CA increased by 0.81 D in the first month (p < 0.001 for both comparisons). The increases in K2 and CA were 0.7 D and 0.63 D, respectively, in Group 2 (p < 0.001 and p = 0.004, respectively). At the postoperative third month, both groups demonstrated statistically significant persistent elevations in K2 and CA values (p < 0.05 for all comparisons) compared to preoperative measurements. Group 1 exhibited statistically significant decreases in both IOL power calculations (0.43 D according to the Barrett formula and 0.40 D according to the SRK/T formula, p < 0.001, for both) and ICA (38.1 ± 4.7° vs. 35.8 ± 4.1°, p = 0.009) measurements at the only one-month postoperative follow-up. IOP, AXL, and ACD measurements did not exhibit any significant changes in both groups at the first and third postoperative months.
conclusionIn addition to changes in keratometry and CA, blepharoplasty with muscle excision significantly decreased IOL power and ICA. It may be beneficial to inquire about recent blepharoplasty history and the surgical technique employed in patients scheduled for cataract or refractive surgery.
