Clinical and economic impacts of optical coherence tomography prior to cataract surgery in a low-to-middle-income country.

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: Integrating optical coherence tomography (OCT) into the pre-surgical stage of cataract management holds significant clinical and economic potential, particularly in low-to-middle-income countries like Kazakhstan. Objective: This study aimed to evaluate these impacts by prospectively recruiting 225 patients, aged 71 ± 6 years, from two ophthalmology surgical centers in Almaty, Kazakhstan. Methods: Patients undergoing phacoemulsification of cataracts with monofocal intraocular lens (IOL) implantation between January 2022 and December 2023 were divided into two groups: the OCT group (n=75) received pre-operative OCT, while the Control group (n=150) did not. Visual acuity (VA) was measured pre- and post-surgery, and the cost-effectiveness of the surgical strategies was analyzed. Results: The OCT group experienced a significantly greater improvement in VA (-0.647 ± 0.232 logMAR) compared to the Control group (-0.543 ± 0.244 logMAR), with a notable interaction between time and group (F(df) = 396.5, p< 0.001). Additionally, pre-existing concomitant diseases were diagnosed in 24.8% of cases in the OCT group and 31% in the Control group. Conclusion: The economic analysis revealed that the integration of OCT facilitated combined surgical procedures during a single operative session, thereby reducing overall costs. These findings suggest that implementing OCT in the pre-surgical stage of cataract management can significantly enhance visual outcomes and decrease the cost of ophthalmology services in Kazakhstan.
