Cataracts in Nigeria: Prevention, Timing, and Recovery

Nigeria's Leading Cause of Blindness

Cataracts — clouding of the eye's natural lens — account for over 40% of blindness in Nigeria. The country has one of the highest rates of cataract blindness in the world, driven by intense UV exposure, nutritional deficiencies, uncontrolled diabetes, and limited access to surgical services. Yet cataract surgery has a 95%+ success rate and transforms quality of life.

Why Cataracts Develop Early in Nigeria

• UV radiation — Lagos's proximity to the equator and limited UV protection accelerate lens oxidative damage
• Diabetes — uncontrolled blood sugar causes glycation of lens proteins, dramatically accelerating cataract formation
• Nutritional deficiencies — antioxidant vitamins (C, E) and lutein/zeaxanthin protect the lens; deficiency accelerates oxidative damage
• Steroid use — long-term oral or topical steroid use is a major cataract driver; common in Nigeria given widespread self-medication
• Smoking and alcohol — both increase oxidative stress in the lens

Slowing Progression Nutritionally

• Vitamin C at therapeutic doses — directly protects lens proteins from oxidation
• Lutein and zeaxanthin — concentrated in the lens and retina; found in egg yolks, dark leafy greens
• Vitamin E — fat-soluble antioxidant protecting lens membranes
• Blood sugar optimisation — the single most impactful intervention in diabetics

When to Consider Surgery

Surgery is indicated when cataracts interfere with daily activities — driving, reading, recognising faces. FXMed facilitates referral to trusted ophthalmologists in Lagos and provides pre- and post-operative nutritional support to optimise healing outcomes.
