Summary
Global cataract surgery rates and coverage are insufficient, particularly in lower-income nations. Factors like economic status and healthcare access significantly impact cataract surgical coverage (CSC), with COVID-19 further hindering progress.
Area of Science:
- Ophthalmology
- Public Health
- Global Health
Background:
- Cataract surgery is a critical intervention for vision restoration.
- Understanding global disparities in cataract surgical rates and coverage is essential for public health initiatives.
Purpose of the Study:
- To determine the worldwide distribution of cataract surgery.
- To assess recent trends in cataract surgical coverage (CSC).
Main Methods:
- Systematic review of global cataract surgical rates (CSR) and coverage data.
- Analysis of factors influencing surgery distribution, including socioeconomic status and healthcare access.
Main Results:
- Cataract surgical rate (CSR) varies widely globally (36–12,800 per million).
- Average cataract surgical coverage (CSC) is often below 50%, with significant differences between CSC and efficient CSC (eCSC).
- Older age, male gender, and private insurance are associated with higher surgery rates; COVID-19 negatively impacted rates.
Conclusions:
- Cataract surgery rates and coverage remain inadequate in many regions.
- National economic status is a primary determinant of surgery quantity and accessibility.
- Government insurance programs and accessible healthcare services can improve cataract surgery provision.

5.7K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

507
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
