What is a Cataract?

A normal, healthy lens inside the eye is clear and transparent, allowing light rays to pass through easily. A cataract is a condition where this lens becomes cloudy or opaque.

  • When the lens becomes cloudy, light rays are blocked.
  • Over a period of time, vision becomes progressively more dull and blurry.
  • If left untreated, a cataract can eventually lead to a complete loss of vision.

What are the Symptoms of a Cataract?

Common symptoms include:

  • Slow, painless, and progressive blurred vision.
  • Feeling as though you are seeing through a frosted or fogged-up glass.
  • Images appearing blurry, yellow, double, or multiple.
  • Glare and halos, especially when driving at night.
  • Frequent changes in your glasses prescription.

What Causes Cataracts?

While aging is the most common cause, other factors include:

  • Common: Ageing (degeneration) and long-term ultraviolet (UV) ray exposure.
  • Other: Diabetes, eye injuries, or long-term use of medications like steroids.
  • Rarely: Congenital (present since birth).

When is the Best Time to Treat a Cataract?

The old concept that a cataract must be "mature" or "ripe" is outdated. With modern technology, we believe any cataract that hinders your day-to-day activities—like reading, driving, or working—should be treated.

Delaying surgery can make the cataract harder (hyper-mature), making the procedure more complex. In rare cases, it can lead to complications like glaucoma or permanent vision loss.

Cataract Surgery and Recovery

Cataract surgery is a safe, quick, and highly effective procedure. At Trivision, we specialize in modern Micro-Incision Cataract Surgery (MICS):

  • Performed through a tiny 2.2 mm micro-incision.
  • Uses ultrasonic energy (Phacoemulsification) to gently dissolve the cataract.
  • Requires minimal or no anesthesia (only numbing drops).
  • Vision typically recovers within a few hours.
  • You can resume professional work and daily activities within 2-3 days.

Advanced Intra Ocular Lens (IOL) Options

During surgery, the cloudy natural lens is replaced with a clear, artificial Intra Ocular Lens (IOL). We offer a full range of premium IOLs to match your lifestyle, allowing you to reduce or even eliminate your dependence on glasses.

Robotic (Femtosecond) Cataract Surgery

This is the most advanced option. A special Femtosecond Laser robotically performs the key steps of the surgery—including the openings and lens fragmentation—with unmatched precision. This makes the surgery even safer, easier, and more accurate, especially when implanting premium lenses.

Types of IOLs

  • Aspheric IOLs: Provides enhanced image quality, high-contrast, and clear vision, especially useful for night driving.
  • Toric IOLs: Corrects astigmatism (cylindrical power) at the time of surgery, reducing the need for glasses for distance.
  • Multifocal/Trifocal IOLs: Provides a full range of vision (distance, intermediate, and near), allowing you to be spectacle-free for most activities.
  • Extended Range (EDOF) IOLs: Provides excellent distance and intermediate (computer) vision, with less glare or halos than some multifocals. You may only need small reading glasses for very fine print.

Your Cataract Questions Answered by Bandra Experts

A cataract is the clouding of the eye's natural lens, which is normally clear. This clouding blocks light from passing through, causing vision to become blurry, dull, or like looking through a fogged-up window.

The most common symptoms are slow, painless blurring of vision, increased glare or halos around lights (especially at night), colors appearing faded or yellow, and needing frequent changes to your glasses prescription.

You should consider surgery as soon as the cataract starts to interfere with your daily life, such as reading, driving, or working. The old idea of waiting for it to "ripen" is outdated. Modern surgery is safest when done on earlier-stage cataracts.

Yes, modern cataract surgery (like MICS or Robotic Laser) is one of the safest and most successful surgical procedures performed worldwide. Serious complications are extremely rare.

No, a cataract cannot reoccur. Months or years later, some patients may develop a "secondary cataract" (PCO), which is a clouding of the thin membrane behind the new lens. This is not a real cataract and is permanently corrected with a simple, painless 5-minute YAG laser procedure in the clinic.

This is an advanced, bladeless procedure where a high-precision Femtosecond Laser robotically performs the most critical steps of the surgery. It makes the procedure even more precise, gentle, and safe, and is especially recommended for implanting premium IOLs (like Trifocal or Toric lenses).

  • Monofocal: Provides clear vision for *one* distance (usually far). You will need reading glasses.
  • Trifocal/Multifocal: Provides clear vision for *all* ranges (distance, intermediate, and near). This is the best option for becoming spectacle-free.
  • EDOF (Extended Range): Provides clear distance and intermediate (computer) vision, with less glare than trifocals. You may still need light reading glasses for very fine print.

Recovery is extremely rapid. It is a walk-in, walk-out procedure. Vision typically recovers within a few hours, and you can resume most normal activities like working on a computer within 2-3 days. You will need to use eye drops for a few weeks.
