Cataract surgery in the extremely small eye: morphology, comorbidities and outcomes in 300 eyes.
Article in The British journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
BACKGROUND/
aimsData on morphological characteristics and outcomes of extremely short eyes undergoing cataract surgery is sparse. Thus, an in-depth characterisation of eyes implanted with a high-power intraocular lens (IOL) (>30 dioptres) was performed.
methodsIn this retrospective cohort study from January 2009 to October 2023, 300 eyes of 191 patients undergoing cataract surgery with extremely short axial length requiring the implantation of a high power IOL>30D were included. Eyes were categorised into the morphologies of nanophthalmos (N), relative anterior microphthalmos (RAM) and high or low/moderate hyperopia (HH and MH). Comorbidities, intraoperative and postoperative complications, preoperative and postoperative refraction and visual outcomes were investigated.
resultsMean preoperative spherical equivalent (SE) was +6±2.85 D. The mean axial length was 20.68±0.92 mm. 19.3%, 45.3%, 22.7% and 12.7% of the studied eyes were categorised as MH, HH, N and RAM, respectively. Amblyopia (14.7%), previous strabismus surgery (7.3%), glaucoma (12.7%) and previous iridotomy (9.4%) were prevalent. Postoperative SE was -0.42±1.56 D. Preoperative Corrected Distance Visual Acuity (CDVA) and postoperative Uncorrected Distance Visual Acuity (UDVA) were not significantly different (0.34±0.39 Logarithm of the Minimum Angle of Resolution (logMAR) vs 0.47±0.38 logMAR, respectively, p=0.47), postoperative CDVA was slightly improved (0.28±0.31 logMAR, p=0.02). The narrow anterior chamber angle was significantly alleviated, posterior capsule rupture rates (3%) were within previously reported ranges.
conclusionsLens surgery is safe, improves the anterior chamber situation but is rather imprecise in extremely short eyes. Of all subtypes, nanophthalmic eyes showed compromised outcomes. Postoperative CDVA is only slightly improved to preoperative CDVA, while postoperative UDVA closely resembles preoperative CDVA. Surgery thus provides spectacle independence leading to good patient satisfaction.
