Comparison of flange creation in three-piece intraocular lenses between high- and low-temperature cautery.
Article in BMC ophthalmology, 2025. 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
backgroundTo compare flange creation using high- vs. low-temperature cautery for three piece intraocular lenses (IOLs) with PMMA and PVDF haptics.
methodsThe ends of the haptics from ten three-piece IOLs with PMMA haptics (AR40, Johnson & Johnson, USA) and ten three-piece IOLs with PVDF haptics (PU6AS, KOWA, Japan) were each heated for 1 mm to form a flange-using low-temperature cautery (593 °C) on the ipsilateral haptic and high-temperature cautery (1205 °C) on the contralateral haptic. Flange size, shape, and formation time were analysed.
resultsThere were no differences in flange shape and flange size between high- and low-temperature cautery for each haptic type (p > 0.05). Average flange size of the AR40 IOL and the PU6AS IOL were 422 ± 22 μm and 363 ± 14 μm, respectively. Haptic diameter were 172 ± 5 μm and 126 ± 3 μm, respectively. The shape of the AR40 IOL flange was conic and the shape of the PU6AS IOL flange was mushroom-like, independent of cautery temperature. Flange formation time was 1.7 ± 0.6 s with the high-temperature cautery and 3.7 ± 0.6 s with the low-temperature cautery, regardless of the haptic material.
conclusionsFlange size and shape in PMMA and PVDF haptics are independent of low- and high-temperature cautery. However, the extended flange formation time associated with low-temperature cautery may allow for greater control during flange creation.
