Cataract Surgery

Over fifty percent of people over the age of 60, and quite a few younger than that, suffer from cataracts.  In fact, cataracts are so common it is said that everyone will develop a cataract if they live long enough.

A cataract is a progressive clouding of the eye's natural lens that interferes with light passing through to the retina.  Sufferers usually describe the condition as being similar to looking through a waterfall, or a piece of wax paper, with gradual blurring or dimming of vision.

Reading may become more difficult and driving a car can actually become dangerous.  Cataract sufferers may also be troubled by a bothersome glare, halos around lights, or even double vision.  And as the cataract becomes worse, frequent changes in eye-glass prescriptions may become necessary. 

Currently there is no medical treatment to reverse or prevent the development of cataracts.  Once they form, there is only one way to achieve clear vision again, and that is to physically remove the cataract from the eye.

In your parent's or grandparent's day, cataract surgery was considered risky, required a lengthy hospital stay and was usually postponed for as long as possible.  Today, cataract surgery is performed on out-patient basis and takes only a few minutes.  Patients can then go home and rest in comfort and avoid the inconvenience and expense of staying in a hospital.

Your cataract will be removed with an advanced technique called phacoemulsification, or small-incision cataract surgery.  Using only a topical anesthetic, a "stair-stepped" incision of about 1/8" is made in the sclera (white part of the eye), or in the clear cornea (just above the area where the cornea meets the sclera).  The cataract is then broken into microscopic particles using high energy sound waves and gently suctioned from the eye.  Then, to compensate for the removal of the eye's natural lens, an intra-ocular lens (IOL) is implanted into the eye.  After using this special "stair-stepped" incision, the eye remains tightly sealed by the natural outward pressure within your eye.

Everyone heals somewhat differently, but many cataract patients report improvement in their vision almost immediately after the procedure.  Most patients return to their normal work and lifestyle routines within a day or two.

According to a survey conducted by the American Society of Cataract and Refractive Surgery, more than 98% of cataract patients had their vision successfully improved after surgery.  Many patients experienced vision that is actually better than before they developed cataracts.  Once removed, cataracts will not grow back.  However, some patients may experience clouding of a thin tissue called the capsule or "bag" that holds the IOL.  In most cases a laser is used to painlessly open the clouded capsule and restore clear vision.

It can take months or years for a cataract to develop.  How do you know when it is time to have a cataract removed?  The answer is quite simple.  The time to have your cataract removed is when you believe your quality of life would be better if you could see better.  Only you can decide when it is time to open your eyes to a bright, clear world.

Because cataract surgery can be done with just topical anesthesia, patients typically feel nothing during or after the procedure.  Previously, a needle was used to inject the anesthetic.  However, with all the latest advancements, including the smaller incision, we can now use eye drops to numb the eye, which means no stick of a needle before surgery.  The major advantage of not having to wear a patch, besides patient comfort, is that patients can immediately see the improvement in their vision.

For many years most patients who underwent cataract surgery still needed to wear glasses to read.  New technology now affords the patient several choices of lens implants that reduce or eliminate the need for glasses after surgery. 

Here is a brief description of the new lenses and how they perform:

ReZoom – offers good distance vision and good vision when working on a computer, but only fair close-up vision and may produce glare and halos while driving at night.

Crystalens – offers good distance vision, good intermediate vision, but only fair close-up or reading vision. 

ReSTOR -   offers good distance vision, good close-up or reading vision, fair intermediate vision and 15-20% of people reported difficulty driving at night due to glare and halos.

Tecnis -   this lens has been approved by the FDA for improved functional vision. Patient has the ability to see well even in low-light situations like driving at night, and improved vision for distance viewing.  With the Tecnis lens you may still need to wear glasses for close-up tasks or reading. 

The decision on what lens implant is best for you should be determined by you and your surgeon based on your expectations of your vision after surgery and your lifestyle.
