Cataract / Laser-Assisted Cataract Surgery / Crystalens

What are Cataracts? Cataracts develop slowly with age and cause one’s vision to become blurry or dim. Visual loss occurs when the lens becomes opaque and light is prevented from focusing on the retina. Distortion of the light passing through the lens results in distorted, clouded vision. Patients also note that images no longer appear as bright or colorful as they once did, comparing their vision to looking through a dirty windshield. The following factors can increase your risk of developing cataracts:

  • Advancing age
  • Diabetes
  • A family history of cataracts
  • Extensive exposure to sunlight
  • Smoking
  • Obesity
  • High blood pressure
  • Previous eye surgery
  • Previous eye injury or inflammation

As we age, proteins gather on the surface of the lens, causing it to harden and become less flexible.  As this layer of proteins thickens, patients gradually lose visual clarity and, if left untreated, cataracts can lead to significant visual impairments and interfere with daily activities. Symptoms of Cataracts As cataracts first develop, you may not notice any changes to your vision. However, it is important to visit an Dr. Yee or your ophthalmologist when you notice the following symptoms:

  • Cloudy or blurry vision
  • Difficulty seeing at night or in low light
  • Sensitivity to glare or light
  • Seeing halos around lights
  • Faded colors
  • The need for brighter light to see or read
  • Double vision in one eye

To determine if you have cataracts, Dr. Yee will dilate your eyes with eye drops so that he can examine your cornea, lens and iris.  If you have cataracts, surgery is the only way to remove the obstruction and return your sight to the clear vision you once enjoyed.

Cataract Surgery

During cataract surgery, Dr. Yee will make a small incision in the front of your eye and insert a tiny instrument that uses high-frequency ultrasound to break up the cloudy lens and remove it.  He will then place an intraocular lens (IOL) made of plastic, silicone or acrylic in your eye.  This new lens will contain your prescription, become a permanent part of your eye and allow light to pass through and focus on your retina, just as your natural lens once operated. Cataract surgery is a 15-30 minute procedure and is performed in an outpatient setting. Patients are treated with an anesthetic and most experience little to no discomfort.

Laser-assisted Cataract Surgery

The Alcon  LenSx® Laser System is FDA approved  for laser-assisted cataract surgery.  The LenSx® Laser was the first femtosecond laser cleared for use in cataract surgery. The LenSx® Laser System continues to lead the way in refractive cataract surgery and a technology that is worth looking into.  While this is not completely covered by your insurances, the advantages the laser offers is worth every bit of the extra cost. If you are eligible for laser-assisted cataract surgery, it offers greater precision, repeatability and safety.  This precision is particular evident when using this technology with premium intraocular lenses such as the Crystalens (see below).  For more information on cataracts and ALCON LENSX fento-second laser, visit

If you are experiencing symptoms of cataracts, Dr. Yee can restore your sight safety, quickly and with lasting results.  Call his office at 713-306-3051 or 832-289-2020 to schedule an eye exam today.


Having cataracts doesn’t mean a lifetime of walking around in a haze. Today’s approach to the treatment of cataracts involves the removal of the natural crystalline lens and implantation of an intraocular lens (IOL). In the majority of his cataract surgeries, Dr. Yee uses Crystalens® — an IOL that performs double duty both as a lens and presbyopia (near and immediate vision) corrector.
