This shape changes how light rays enter the eye, leading to blurred vision. Many people with astigmatism have nearsightedness (myopia) or farsightedness (hyperopia).

In these areas, the myopia prevalence in young people is about 80 -90%, and the prevalence of high myopia is higher (10–20%) (1). Unfortunately, patients with high myopia have an increased risk of ...

The RLRL therapy trial recruited participants with myopia (−0.50 to −6.00 D), astigmatism <2.50 D, and best-corrected vision ≥1.0. The exclusion criteria included ocular diseases, systemic conditions, ...

After adjusting for sociodemographic factors, parental astigmatism, and child myopia, the pandemic was associated with a 20% increase in the risk of refractive astigmatism (OR 1.20, 95% CI 1.09-1. ...

Each degree of myopia (diopter) that is prevented reduces the risk of myopic maculopathy by 40 per cent, which represents a very powerful initiative, unparalleled in terms of public health.

The number of relevant studies is very limited to date and there is no literature directly addressing this question, so we used raw data from individual relevant clinical trials to address this issue, ...

Myopia, or nearsightedness as it is called commonly, often goes undetected in children for extended periods due to its gradual onset and the subtle nature of its symptoms.

Projections from this study suggest that the prevalence of myopia could reach 31.89% by 2030, 40.01% by 2040 and a concerning 48.14% by 2050. If this trend continues, the generational impact—a ...

Spherical equivalent The spherical equivalent of astigmopia (SE a) is the spherical power that places the CLC on the retina without altering the amount of astigmatism. It typifies and quantifies the ...

Myopia, or nearsightedness, is a vision condition where close objects look clear but far objects look blurry. This occurs when the shape of the eye causes light rays to bend and focus in front of ...

The impact of this problem does not come until much later, he warned. An adult with high myopia has a much higher risk of complications that can lead to blindness, for example, cataracts and glaucoma.

LASIK surgery is a common vision correction procedure for people with myopia (nearsightedness), hyperopia (farsightedness) or astigmatism.1 An alternative to wearing glasses or contact lenses, the ...
