    What is Cataracts?

    Understanding About

    Cataracts refer to the clouding of the typically clear lens of the eye, causing vision impairment akin to looking through a frosted or fogged-up window. While initially, cataracts may not significantly affect eyesight, they gradually worsen over time, making activities like reading, driving at night, or discerning facial expressions challenging. 

    Initially, remedies like brighter lighting and glasses may suffice, but if vision impairment interferes with daily tasks, cataract surgery becomes necessary.

    Fortunately, cataract surgery is generally regarded as a safe and effective procedure.

    Cataracts FAQs


     Cataracts do not always interfere significantly with vision. They start small and are almost imperceptible to the patient. If a cataract progresses to the point that vision is impaired or lifestyle is affected, it should be removed. If it remains stable, surgery may not be necessary.

    Be sure to have regular comprehensive vision check-ups with your eye doctor to monitor cataract progression so that, together, the decision to have cataract surgery can be made.

    It is not possible for a cataract to “grow back” because the lens where the cataract forms has been removed and replaced. The intraocular lens (IOL) implant never needs maintenance or replacement. In some patients, a cloudy film can form behind the implant on the lens capsule membrane, usually a few months after the original cataract surgery. This condition is called posterior capsular opacification, or secondary cataract (because it seems as if the cataract has returned).

    During cataract surgery, your surgeon will use a local anesthetic (numbing eye drops) to keep you from experiencing pain during your procedure. You will also be given a mild sedative to help you relax. Depending on the patient and type of procedure, additional medication may be utilized.

    As the medications wear off, you may feel a scratchy sensation or slight soreness in your eye the first day. Over-the-counter pain relievers can be used to alleviate discomfort. If necessary, your doctor will prescribe stronger pain medication.

    Cataracts usually affect patients over age 55, however, anyone can develop one. By the age of 65, 50% of people have developed a cataract and almost everyone over age 75 has at least one cataract. They occur due to the natural aging process.

    In the rare instance that a problem arises with your intraocular lens, adjustments can be made to correct visual acuity. The IOL can be repositioned or replaced with a different type of lens. It is highly unusual that a cataract procedure needs to be revised.
