Cataract FAQS

As we age, a cloudiness develops on the eye’s lens, causing the vision to blur. Cataracts may also be associated with diabetes or, in rarer cases, eye injury.

The progression of cataracts varies greatly among individuals. In some cases, cataracts can develop slowly over many years, while in others, they can progress more rapidly over a few months. Factors influencing the speed of cataract development include age, genetic predisposition, underlying health conditions such as diabetes, prolonged exposure to sunlight, smoking, and certain medications. Regular eye examinations are essential to monitor the development and determine the appropriate time for treatment.

Cataracts are primarily treated through surgery, which is the most effective and common method. The procedure involves removing the cloudy lens and replacing it with a clear artificial lens, known as an intraocular lens (IOL). This surgery is typically performed on an outpatient basis and has a high success rate with minimal complications. Non-surgical treatments, such as updated prescriptions for eyeglasses or contact lenses, can help manage symptoms in the early stages, but they do not stop cataract progression.


Eye doctors have not yet found a proven method of preventing cataracts, however, there are some lifestyle factors that may increase you risk of developing cataracts. It is suggested that to maintain eye health one should avoid smoking, excessive alcohol consumption, excessive exposure to sunlight, and manage obesity and other health problems. Some eye doctors also recommend a healthy diet of fruits and vegetables, rich in antioxidants, to reduce your risk of developing cataracts.

Cataracts progress so slowly that most people don’t realize they have the condition until its later stages. When symptoms become more pronounced, blurred vision, sensitivity to light, and/or “halos” around bright lights (especially at night) are common. Other symptoms include double vision, a faded or yellowish hue to bright colors, and the need to frequently adjust your eyeglass prescription.

An eye surgeon numbs the nerves in and around your eye with a local anesthetic. Then, after making a small incision, the surgeon removes the cataract-clouded lens and replaces it with a new intraocular lens made of plastic, silicone, or acrylic. The incision is then closed, concluding an outpatient operation that typically takes under 15 minutes. Over the course of the recovery process, the intraocular lens fuses with the eye and becomes a permanent part of the eye’s structure.

Untreated cataracts will almost always continue to progress over time, causing loss of vision. If cataracts are left untreated for long periods of time they can even cause a person to become legally blind, not only making day to day activities difficult but also potentially dangerous. If you feel your vision is deteriorating further, it is important to see you eye doctor for an exam as soon as possible.

Patients can choose from a variety of premium lens options. Depending on the type of lens you select, you may still need to wear reading glasses after surgery. That said, whichever replacement lens you select, your vision will typically be clearer and brighter after cataract surgery.

The short answer is no. However, some patients report experiencing blurry vision reminiscent of their preoperative vision years after cataract surgery. These “secondary cataracts” occur when scar tissue forms around the lens capsule that holds replacement lenses in place. Undergoing a simple outpatient procedure known as a YAG laser capsulotomy can resolve this issue.

The cost of cataract surgery depends on a number of factors, including the type of replacement lens used and the surgical technique — laser or traditional — deployed during the operation. If you have private health insurance or Medicare, the cost of cataract surgery will likely be partially or completely covered.

Always check with your insurer to see exactly what is and is not covered. Insurers may only pay for the medical portion of the surgery once the insured’s vision has deteriorated to the point where it negatively impacts their daily activities. We work with our patients to craft affordable financing plans that meet their financial needs.

If Medicare deems cataract surgery medically necessary, they will pay 80% of the total medical costs associated with the procedure. Medicare will also cover one pair of post-cataract surgery eyeglasses.

The procedure ranks among the safest medical treatments available for vision correction, and more than 3 million cataract surgeries are performed in the United States every year. As with any surgery, there is a risk of bleeding and infection, and more serious complications like retinal detachment are possible yet infrequent. Your doctor will go over all the possible risks prior to the operation and suggest an array of precautions you can take to ensure your procedure goes smoothly.

A full recovery from cataract surgery typically takes about four weeks. Immediately after your surgery, your vision will be blurry as a result of your eye adjusting to the replacement lens. During the first several days of the recovery process, you will be asked to wear an eye shield at night to prevent you from rubbing your eyes in your sleep.

As your eyes are healing, your should avoid lifting heavy objects and extreme bending over at the waist. If you experience severe pain or don’t believe your recovery is progressing on schedule, contact your eye care specialist immediately.

The timing of cataract surgery can depend largely on the individual patient. If vision impairment from cataracts is negatively affecting your day to day life, it might be time to consider cataract surgery.

Cataracts and Glaucoma are both conditions that cause the loss of vision. However, a cataract is the clouding of the eye’s lens over time, causing vision to become hazy, whereas, Glaucoma is a condition in which there is a buildup of pressure in the eyes that causes damage to the optic nerve that if not treated can result in irreversible blindness. Cataracts and Glaucoma can both be treated surgically and the outcomes are generally positive, however, in the case of Glaucoma, early diagnosis and treatment is necessary because the loss of vision cannot be reversed, as it can with cataract surgery.
