CATARACT SURGERY

A cataract is when the lens in your eye becomes cloudy and makes it hard to see clearly. The lens is usually clear and helps you see sharp images. When it gets cloudy, your vision may become blurry, lights may seem too bright, and night driving can be difficult. Cataracts are common in older people but can also happen from injuries, health problems, or too much sun exposure. They grow slowly but can be easily treated with surgery.

The Most Common Cataract Symptoms Include:
  • Blurry or Cloudy Vision: Objects may seem out of focus, as if you're looking through a foggy window.
  • Increased Sensitivity to Light and Glare: Bright sunlight, headlights, or even indoor lights can feel harsh, making it difficult to see clearly.
  • Difficulty Seeing at Night: Nighttime or low-light environments, such as while driving, can become challenging.
  • Dull or Yellowed Colors: Colors may appear faded, less vibrant, or take on a yellowish tint.
  • Halos Around Lights: Bright lights may be surrounded by glowing rings or halos, especially noticeable at night.
  • Single-Eye Double Vision: Some experience double images in one eye, often caused by lens clouding.

TYPES OF CATARACT

Cortical Cataract

Cortical cataracts begin at the edges of the lens and slowly move inward, often leading to visual disturbances such as halos and glare.

Intumescent Cataract

An intumescent cataract occurs when fluid accumulates in the lens, causing it to swell and potentially resulting in rapid and significant vision loss if not treated.

Nuclear Cataract

Nuclear cataracts develop in the center of the lens, typically as part of the aging process, leading to blurred vision and difficulty seeing distant objects.

Posterior Subcapsular Cataract

This type starts at the back of the lens and worsens quickly. It can cause glare and make reading hard. It is often linked to diabetes and steroid use.

Rosette Cataract

Rosette cataracts often form after an eye injury and appear as a star-shaped pattern in the lens. They can affect vision depending on their size and location.

Traumatic Cataract

Caused by an eye injury, a traumatic cataract may develop right away or even years later, leading to blurry or unclear vision.

Frequently Asked Question about Cataract

  • What is the cure for cataract?

    Before exploring the treatment options for cataract or motiyabind, it’s important to first understand what a cataract actually is. Simply put, a cataract refers to the clouding of the eye’s natural, normally clear lens. Although surgery remains the only effective method to treat cataracts, it is not always necessary to undergo the procedure immediately.

  • What are the reasons for getting cataract?

    A major cause of cataract is either an injury to the eye or the natural aging process. In both scenarios, the tissue that makes up the eye’s lens begins to change. As the proteins and fibers in the lens deteriorate, it results in blurred or cloudy vision.

    Additionally, genetic factors or inherited disorders can raise the likelihood of developing cataracts. Other contributing factors include existing eye conditions such as diabetes, previous eye surgeries, or prolonged use of steroids and certain strong medications.

  • What will happen if Eye cataract is left untreated?

    It's best to treat a cataract early, or it can get worse over time and affect your vision. If you wait too long, the cataract can become hard and overgrown, making it more difficult to remove.

    This can lead to problems during surgery. So, as soon as you notice signs of cataract, see an eye doctor. Cataract surgery is safe and works well.

  • What is an Intraocular lens?

    Cataract surgery is typically done as an outpatient procedure, where the surgeon carefully removes the cloudy natural lens and replaces it with a clear artificial lens, also known as an intraocular lens (IOL). Patients have the flexibility to choose from various types of IOLs based on their needs, comfort, and lifestyle preferences.

  • What are the 3 types of cataracts?

    Eye cataracts are generally categorized into three main types: nuclear sclerotic cataracts, cortical cataracts, and posterior subcapsular cataracts. Let’s take a closer look at each type:

    Nuclear sclerotic cataracts

    This is the most common form of cataract, starting with a slow hardening and yellowing of the central part of the lens, known as the nucleus. Interestingly, people with this type may notice a temporary improvement in their near vision, although this effect doesn’t last.

    Cortical Cataracts

    Cortical cataracts develop in the lens cortex and gradually spread inward toward the center. When light passes through the affected lens, it can scatter, causing glare, blurry vision, and issues with depth perception. Individuals with diabetes are more prone to developing this type of cataract.

    Posterior Subcapsular Cataracts

    These cataracts form on the back surface of the lens, just beneath the lens capsule, hence the term "subcapsular." They can interfere with reading and night vision, often progressing faster than other types.
