AI Article Synopsis
- * Results showed that 68.02% of the students had myopia and 5.90% had high myopia, with even higher rates of 85.54% and 13.13% among grade 9 students, respectively.
- * Key risk factors identified included being female, having a family history of myopia, excessive homework time, and inadequate sleep, while doing eye exercises was linked to a lower risk of developing myopia.
Article Abstract
Objectives: The aim of the study was to identify the prevalence and risk factors of myopia and high myopia in students from primary school and junior high school in Shandong.
Methods: A total of 35,614 subjects completed the visual acuity test, refraction error measurement, and questionnaire in 2019. The visual acuity test was performed using the standard logarithmic visual acuity chart and the refractive error was measured by an automatic refractometer without cycloplegia.
Results: The average age was 12.38 ± 1.78 years, with 18,501 boys and 17,113 girls. The overall prevalence of myopia and high myopia was 68.02% and 5.90%, respectively, and reached up to 85.54% and 13.13% for the grade 9 students. The risk factors included girls, parental myopic history, time spent doing homework, and less sleep time. Performing eye exercise was significantly associated with a lower risk of myopia. Use of mobile devices and reading while lying down were only related to myopia, not high myopia.
Conclusion: The prevalence of myopia and high myopia is at a high level. In addition to genetic factors, continuous close work and a lack of sleep was an important factor associated with children myopia and high myopia.

Effect of size of capsulorhexis on the outcome of cataract surgery: a protocol for systematic review and individual participant data meta-analysis.
BMJ Open
December 2024
Department of Ophthalmology, The Second Hospital of Shandong University, Jinan, Shandong, China
Introduction: In the era of functional intraocular lens (IOL) implantation, it is crucial to investigate the influence of different capsulorhexis sizes (including the diameter of the capsulorhexis, area of the anterior capsule opening, anterior capsule coverage, centration and circularity of the capsulorhexis) on the postoperative outcomes (eg, visual acuity, capsule shrinkage, IOL stability and intraocular pressure) in patients undergoing cataract surgery. This is particularly important in patients with high myopia or diabetes mellitus. The proposed protocol aims to enhance the transparency of our research and offer references for future studies.

Clinical Relevance: Knowledge of contact lens prescribing trends can (a) assist practitioners to benchmark their own prescribing habits, (b) help the contact lens industry understand preferred products, and (c) support academics in scholarly writings.
Background: This work aims to document contact lens prescribing trends in Australia over the past quarter of a century.
Methods: An annual survey of contact lens prescribing trends was conducted in Australia each year from 2000 to 2024, inclusive, by asking optometrists to provide information relating to 10 consecutive contact lens fits undertaken between January and March.
