Incidence and Characteristics of Intraocular Lens Dislocation in South Korea from 2002 to 2021: A Nationwide Population-based Study.

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
purposeThis study aimed to analyze the incidence and characteristics of intraocular lens (IOL) dislocation after cataract surgery in South Korea.
methodsWe retrospectively analyzed the incidence of IOL dislocation after cataract surgery in patients diagnosed between 2002 and 2021. Data of all pseudophakic patients who underwent secondary IOL or IOL exchange surgeries due to IOL dislocation were extracted from the Korean National Health Insurance System database and the Korean Standard Classification of Diseases 7th Revision codes. The incidence per 1,000,000 person-years and corresponding 95% confidence intervals (CIs) were calculated.
resultsBetween 2002 and 2021, 39,965 of the 4,848,125 pseudophakic patients (0.82%) were diagnosed with IOL dislocation and surgically treated. The incidence of IOL dislocation requiring surgery in pseudophakic patients was 28,900 per 1,000,000 person-years (95% CI, 28,431-29,369), comprising 57,800 cases in male (95% CI, 56,730-58,870) and 10,800 in female patients (95% CI, 10,523-11,077), and the mean male to female ratio was 5.35. The incidence rate peaked in younger age group below 40 years, showing 107,000 per 1,000,000 person-years (95% CI, 102,900-111,100), and the average age of IOL dislocation requiring surgery was 68.1 ± 10.7 years. The average time lapse from cataract surgery to secondary IOL surgery due to IOL dislocation was 4.1 ± 4.7 years (median, 2.2 years), and the number of secondary IOL surgery due to dislocation of artificial lensrapidly occurred 10 years after cataract surgery among all age groups.
conclusionsThe incidence of IOL dislocation requiring surgery was higher in younger and male patients. Our findings could be expected to aid establishing future healthcare policies for South Korean populations with an increased risk of IOL dislocation after cataract surgery.
