What Are Cataracts?

A cataract is a clouding of the normally clear lens inside your eye. The lens focuses light onto your retina for sharp vision. When it becomes cloudy, vision may seem as though you’re looking through a foggy or frosted window.

Here are some key points:

  • Cataracts are very common, especially as people age.
  • They can occur in one or both eyes, but do not spread from one eye to the other.

What Causes Cataracts?

Cataracts develop when proteins in the lens break down and clump together, blocking or scattering light. There are several possible causes besides age.

These include:

  • Aging is the most common, natural changes in the lens result in clouding over time.
  • Eye injuries, inflammation, or previous eye surgery.
  • Medical conditions such as diabetes.
  • Long-term use of corticosteroid medications.

These include:

  • Congenital cataracts present at birth or developing in early childhood.
  • Radiation exposure.

Signs and Symptoms of Cataracts

Cataracts can affect vision in various ways, often starting subtly and worsening gradually.

Common symptoms include:

  • Blurry or cloudy vision.
  • Difficulty seeing at night or requiring more light to see.
  • Increased sensitivity to glare or seeing halos around lights.
  • Colors appearing faded or yellowed.
  • Double vision in one eye.

Cataracts usually do not cause pain, eye redness, or sudden vision loss, if you have these symptoms, see an eye doctor promptly.

Types of Cataracts

Ophthalmologists classify cataracts based on where they form in the lens and how they affect vision.

Affect the center of the lens, leading to gradual vision changes and often yellowing or browning of vision.

Start as white, wedge-shaped streaks at the edges of the lens and progress toward the center, disrupting light passage.

Form at the back of the lens, often causing glare, light sensitivity, and difficulty reading in bright light.

Present at birth or early childhood; may require early intervention to prevent long-term vision loss.

Who Is at Risk?

Anyone can develop cataracts, but certain factors increase the likelihood.

These include:

  • Age over 60 years.
  • Family history of cataracts.
  • Diabetes, prior eye injury, or long-term steroid use.
  • Excessive sun exposure without eye protection.
  • Smoking or high alcohol consumption.

How Are Cataracts Diagnosed?

Diagnosis involves a comprehensive eye examination by an ophthalmologist, often a cataract surgeon.

These may include:

  • Visual acuity testing (eye chart).
  • Slit-lamp examination to view the eye structures in detail.
  • Retinal exam after pupil dilation.

How Are Cataracts Treated?

Treatment depends on the severity of vision impairment and its effect on daily activities.

Options include:

  • Updated eyeglass prescription.
  • Brighter lighting at home.
  • Anti-glare sunglasses for outdoor use.

If vision loss significantly interferes with daily life, surgery offers a safe, effective solution. The cloudy lens is removed and replaced with a clear intraocular lens.

Surgery timing is individualized, many people wait until cataracts reduce quality of life. Your cataract surgeon will guide the decision.

How Can You Slow Down Cataract Development?

While cataracts cannot be completely prevented, certain habits may delay progression.

Helpful steps include:

  • Wear sunglasses that block ultraviolet (UV) light.
  • Eat a diet rich in fruits and vegetables packed with antioxidants.
  • Avoid smoking and excessive alcohol use.
  • Manage other health conditions such as diabetes.
  • Schedule regular eye exams, especially after age 40 or with risk factors.

When Should You See a Doctor?

Prompt evaluation ensures timely treatment and protects long-term vision.

Seek care if you have:

  • Blurry vision, increased glare, or halos around lights.
  • Difficulty with reading, driving, or other daily activities.
  • Eye pain, flashes of light, sudden vision changes, or new floaters.

Frequently Asked Questions

Here are answers to some of the most common questions our patients ask about cataracts and treatment.

Cataract surgery effectively restores vision clouded by the lens, but it does not treat other eye diseases such as macular degeneration or glaucoma. Your surgeon will assess your overall eye health to set realistic expectations.

Once removed, a cataract cannot return. However, some people develop posterior capsule opacification (PCO), a clouding behind the new lens, months or years later. This can be quickly corrected with a painless laser procedure.

Most patients notice clearer vision within days, with complete healing in four to six weeks. Avoid heavy lifting, rubbing your eyes, and swimming during early recovery. Your surgeon will give tailored guidance.

Although very safe, cataract surgery carries small risks such as infection, bleeding, swelling, retinal detachment, or increased eye pressure. These are rare, and your surgeon will monitor recovery closely.

Yes. Pediatric cataracts may occur at birth, from trauma, or due to medical or genetic causes. Early diagnosis is critical to prevent permanent vision loss and may require surgery along with ongoing eye care.

Medicare and most private insurance cover standard cataract surgery when medically necessary. Coverage for premium intraocular lenses or added refractive corrections varies, check with your insurance and our office for details.

There is no guaranteed prevention, but UV protection, smoking cessation, a healthy diet, and control of chronic conditions like diabetes can slow their formation.

You may resume driving within days when your vision meets legal requirements and feels comfortable. Always wait for your doctor's approval before driving after surgery.

Many reduce their reliance on glasses, particularly for distance vision, but reading glasses may still be needed depending on the intraocular lens type and your eyes' needs.

Usually only one eye is operated on at a time. The second eye is treated after the first has healed to ensure optimal safety and outcomes.
