FAQs

What is a cataract?

A cataract is the clouding of the natural crystalline lens inside the eye. When we are young the lens is clear and the light rays pass through this clear lens and reach the retina that is located in the back of the eye and this allows us to see our world clearly. However, as we get older and develop a cataract, the lens inside the eye becomes cloudy. Since light can no longer pass aswell through the cloudy lens as it once did when the lens was clear, vision becomes blurred and hazy. Surgery is the number one treatment to remove the cataract from the eye and usually involves a replacement of lens with a lens implant.

What causes cataracts?

A number of factors go into influencing the development of a cataract. The most common factors include age, injury, heredity, eye disease and exposure to the sunlight.

Who is at risk for developing cataracts?

Cataracts are very common and about half of the population will develop a cataract by the age of 65. By the time people reach 75, nearly every one has at least one cataract. Older people are more at risk than younger people.

If I have a cataract, should I wait to have surgery?

Cataracts often go unnoticed for a period of time because they are not developed enough to have a negative impact on your vision. It is a gradual process when the lens changes from a clear lens to a cloudy lens. It is important to schedule annual visits with an eye doctor to monitor the progress of the cataract. The doctor will be able to determine when it is appropriate to have the cataract removed. However, it is an elective surgery and the final decision as to have surgery or not is your final decision.

Is cataract surgery safe?

Cataract surgery is the most common procedure performed in the United States and it is usually very safe. In order to ensure your safety you should consider selecting a surgeon who has years of experience dealing with cataracts.

How are cataracts removed?

The cataract surgery is a relatively quick procedure that involves making a small incision on the cornea. Once the incision has been made an ultrasound "phaco" needle is used to break up the natural lens and then it is removed. After the lens has been removed, a replacement will be inserted, namely, an intraocular lens implant.

What are possible side effects?

Cataract surgery is a very safe procedure but like with any surgery there may be side effects or potential complications. Pain, swelling or bleeding are some of the common ones. You should discuss with your surgeon the likelihood of these side effects or complications.

What happens after surgery?

After cataract surgery there will be a period of recovery, the eyes will have to learn to adjust without being impaired by the cataract. After surgery there may be side effects such as minor irritations, light sensitivity and fluid discharge, all of which are normal and the surgeon will explain to you what needs to be done when experiencing these things. Full recovery time is about 4 to 6 weeks but most of the discomfort will be relieved by two to three days following surgery. You surgeon will schedule a follow-up appointment with you to monitor the progress of the eye.
