Is night driving becoming difficult? Do you see halos around oncoming headlights? These symptoms indicate cataracts, a change in the cataractsprotein structure in the lenses of the eyes. At Princeton Eye and Ear in Lawrenceville, Plainsboro, and Freehold, NJ, your ophthalmologists detect and treat this common eye condition. Dr. Chirag Shah and Dr. Angana Shah are highly trained cataract surgeons, specializing in minimally invasive techniques. You can see clearly once again.

The details on cataracts

Cataracts affect the lenses of the eyes. Located below the outer cornea and focused by the muscles of the colored iris, the lens allows your retina to receive the images you see and to transfer them, via the optic nerve, to the brain. Over time, proteins build-up on the surface of the lens, clouding it and discoloring the images coming into the eye.

Changes in vision due to cataracts begin in one's fifties, says the American Academy of Ophthalmology, but they may not become noticeable until a person has difficulty:

  • Driving at night due to glare
  • Seeing bright colors (images look yellowish)
  • Using a computer due to glare
  • Reading in dimmer light

In the past, people lost a substantial amount of visual acuity due to cataracts. Surgeries were complex, and there was no way to replace the clouded lenses. If people had cataracts removed, they wore thick prescription glasses afterwards.

You may wonder why you are developing cataracts. Aging is the biggest cause. However, the American Academy of Ophthalmology maintains other factors may worsen cataracts, including:

  • Smoking
  • Diabetes
  • Trauma to the eye
  • Medications containing steroids
  • Excessive sun exposure

Treating cataracts

Your Lawrenceville, Plainsboro, and Freehold ophthalmologist uses minimally-invasive, in-office surgery to remove cataracts. This fast, small-incision procedure takes out the clouded portion of the lens, leaving the lens capsule, or outer coating, in place. Then, the doctor inserts a tiny, folded lens implant (intra-ocular lens, or IOL) into the capsule. It unfolds and allows for passage of light into the eye.

Your ophthalmologist will inform you about your particular kind of surgery, preparation for it and what kind of lens you will receive. Depending on their type, lenses correct a variety of issues, including astigmatism, near-sightedness, far-sightedness and more. So, while you expect clearer vision after cataract removal and implantation of an artificial lens, you may be surprised by reduced dependency or complete elimination of glasses or contact lenses.


Cataract surgeries take about 15 minutes. Afterwards, you'll need a ride home from a responsible adult, and you should rest for the remainder of the day. Our doctors may ask you to instill special eye drops, and all surgery patients should:

  • Avoid lifting and other strenuous activity for about a week
  • Wear sunglasses with UV protection
  • Stay out of dusty or high-pollen environments to avoid infection
