What is a cataract?

Contrary to popular belief, a cataract is not a type of “film” that forms over the surface of the eye.  In reality, a cataract is the result of a natural change occurring inside your eye, a gradual clouding that can make your vision less sharp over time.

The eye works much like a camera, and like a camera, depends on clear lens to properly focus images.  A healthy, transparent lens absorbs light and accurately focuses it onto the retina ( the back of the your eye), providing a crisp, clear image.

As we age, however, proteins in the lens begin to clump together, forming opaque clusters.  Over time, these protein clumps will eventually cloud the lens, allowing significantly less light to pass through.  The small amount of the light that does make it to the retina is diffused or scattered, leaving vision unfocused.  These clusters can also change the coloration of the normally clear lens,tinting it a brownish shade that affects color perception.

What causes cataracts?

The majority of cataracts develop on their own as part of the natural aging process.

Trauma to the eye, including injury, burns or surgery.

Toxin, including regular use of tobacco, alcohol or corticosteriods.

Exposure to radiation, X-rays or UV light

Certain diseases, including diabetes, hypothryoidism and glaucoma.

What are the symptoms of cataracts?

Blurred vision

Faded or dull colors

Poor night vision

Sensitivity to light

Left untreated, cataracts have the potential to cause a complete loss of vision.  Thankfully, treating cataracts now involves a safe, relatively simple surgery – an amazing procedure that can literally change the way you see the world.

How are cataracts treated?

The experts at Eye Consultants PC specialize in advanced surgical techniques to surgically treat cataracts. Topical anesthesia ensures your comfort during surgery and allows the surgery to be done without a needle stick near the eye. A process called phocoemulsification is used to break up the cataract and vacuum it away. Then the surgeon inserts an intraocular lens or IOL to replace the natural lens that was removed.


What is an Intraocular Lens?

An intraocular lens or IOL is usually implanted during cataract surgery to replace the clouded natural lens that is being removed. A comprehensive eye examination prior to surgery and discussion with your doctor will determine what type, size and power of IOL is needed. These lens implants are made from a flexible material and folded for insertion into the micro incision used to remove the cataract. Over the past several years there have been many advances in IOLs which have increased the number of lens choices available to patients. Your vision is achieved through a process of consultation with your eye surgeon to select the best lens to achieve your goals.

Standard Lens

For more than 30 years, doctors have treated cataracts by replacing them with a conventional IOL, which allows you to focus clearly at one distance only. Typically, patients would choose to have the doctor aim for the best distance vision with the understanding that glasses would still be needed for close work, such as reading.

Premium Lens
In recent years, however, IOLs have undergone tremendous advances. While your choice was previously limited to selecting a Standard IOL for one focal point, and using eye glasses for everything else; premium lenses can now provide good distance, intermediate and near vision. Our goal when using one of these premium IOL lenses is to provide you with a full range of vision, thus minimizing your dependence on glasses, including reading glasses or bifocals.



Multi-focal lenses work by using various optical zones seen as rings on the surface of the lens. These optical zones have different powers which determine the focal point based on what you are looking at.

Accommodating lenses work by shifting the focal point on hinges to mimic the natural change of focusing power you enjoyed up until about age 40-50. As you get older you develop presbyopic vision which simply means that your eyes have lost the ability to shift a focus point. Reading glasses are commonly required so that you can see things up close. The accommodating lens is designed to allow you to change the focal point of the lens.

These lenses are not for everyone and some additional testing will need to be completed to determine if you are a good candidate for these premium lenses. The majority of patients who have chosen premium IOLs are absolutely amazed with the results and would recommend the procedure to their friends and family who have cataracts.

For patients with astigmatism who are having cataract surgery, you now have an additional option; an IOL that makes it possible to treat the cataract and correct your astigmatism at the same time. These IOLs are called Toric IOLs. Your doctor will recommend the option that is best for you.
If you want to learn more about the life changing procedures involved in modern cataract surgery, we will be happy to answer all your questions. Although most insurance companies cover the cost for removal of your cataract, no insurance company will pay the additional amount charged for Toric, Multi-focal or Accommodative Lenses. If you are interested in any of these products or services, please understand that you will pay an additional fee per eye.
