Chronic Condition

Cataracts

LOW SEVERITY

A clouding of the normally clear lens of the eye, leading to decreased vision. Most commonly age-related but can be congenital or secondary to other conditions. Leading cause of blindness globally but highly treatable.

Symptoms

Cloudy/blurry vision
Increased glare
Difficulty with night vision
Fading colors
Double vision in one eye
Frequent prescription changes
Halos around lights
Need for brighter light

Treatment Options

Updated eyeglass prescription
Brighter lighting
Anti-glare sunglasses
Magnifying lenses
Phacoemulsification surgery
Femtosecond laser surgery
Intraocular lens (IOL) implantation
Medication management of secondary causes

Risk Factors

1Age >60
2UV radiation exposure
3Diabetes
4Smoking
5Obesity
6Hypertension
7Previous eye injury/surgery
8Prolonged corticosteroid use
9Excessive alcohol
10Family history

Diagnostic Methods

  • 1Visual acuity test
  • 2Slit-lamp examination
  • 3Retinal exam
  • 4Refraction and visual assessment
  • 5Contrast sensitivity testing
  • 6Glare testing

Prognosis

Excellent with surgery; 95% achieve improved vision. Surgery is most common procedure in older adults. Without surgery: progressive vision loss to blindness.

Prevention

  • UV-protective sunglasses
  • Regular eye exams
  • Diabetes management
  • Smoking cessation
  • Healthy diet (antioxidants)
  • Limiting alcohol

Research Status

Phacoemulsification with IOL implantation gold standard. Femtosecond laser-assisted surgery improving precision. Extended depth of focus and multifocal IOLs reducing glasses dependence. Eye drops to dissolve cataracts (investigational). Genetic research into congenital forms.
