Cataract Surgery FAQs
Understanding Cataracts and When Surgery Is Needed
A cataract is a clouding of the natural lens inside your eye. The lens sits behind your pupil and normally focuses light onto the retina at the back of your eye. When the lens becomes cloudy, it blocks or scatters light, making your vision blurry, hazy, or dim.
Most cataracts develop slowly over time as part of the natural aging process. You may notice colors appear faded, halos around lights at night, or difficulty reading even with your glasses. These changes happen because the proteins in your lens clump together and lose their clarity.
We typically recommend surgery when cataracts begin to interfere with your daily activities. You might have trouble driving safely, especially at night, or find it hard to read books, labels, or your phone screen.
- Frequent changes in your eyeglass or contact lens prescription
- Double vision in one eye
- Difficulty with hobbies like sewing, golf, or watching television
- Problems seeing in bright sunlight or with glare from headlights
- Colors looking washed out or yellowed
In some cases, we may recommend cataract surgery for medical reasons even if your symptoms are mild. These situations include cataracts causing increased eye pressure or angle narrowing, cataracts that block the view needed to diagnose or treat retina problems, or significant differences in prescription between your two eyes that cannot be corrected with glasses.
Not every cataract needs immediate surgery. In the early stages, updating your glasses prescription or using brighter lighting may be enough to manage symptoms. We often suggest watchful waiting if your vision changes are mild and do not affect your safety or quality of life.
Surgery becomes the better option when vision loss limits what you want or need to do each day. The decision is personal and should reflect your lifestyle, visual demands, and overall health. Our eye doctor will discuss the timing that makes the most sense for you.
Aging is the biggest risk factor, with most cataracts appearing after age 60. However, several other factors can speed up their development or cause cataracts to form earlier in life.
- Diabetes and other metabolic conditions
- Long-term steroid use
- Previous eye injury or inflammation
- Extended exposure to ultraviolet light without eye protection
- Smoking and excessive alcohol use
Preparing for Cataract Surgery
Before surgery, we perform a complete eye examination to measure the size and shape of your eye. These measurements help us select the right power and type of intraocular lens to implant. We also check for other eye conditions that might affect your surgery or recovery.
You can expect several tests, including dilating your pupils, measuring the curve of your cornea, and using ultrasound or optical imaging to see inside your eye. This appointment usually takes about an hour, and you should bring someone to drive you home since your vision will be blurry from the dilating drops.
During cataract surgery, we remove your cloudy natural lens and replace it with a clear artificial lens called an intraocular lens. Standard monofocal lenses provide clear vision at one distance, usually far away, so you may still need reading glasses afterward. Some patients choose monovision targeting with monofocal lenses, where one eye is set for distance and the other for near, to reduce dependence on glasses.
Premium lens options include multifocal and extended depth of focus designs that may reduce your need for glasses at multiple distances. Toric lenses correct astigmatism at the same time. However, multifocal and extended depth of focus lenses can increase halos and glare, especially at night, and may reduce contrast sensitivity. They may not be suitable for all eyes, particularly those with dry eye, macular disease, or irregular astigmatism. We will review which lens type best matches your vision goals, lifestyle, and eye health during your consultation.
Most of your regular medications can continue right up to surgery day. Many blood thinners are continued for cataract surgery, but some cases require adjustment. Your surgeon will coordinate with your prescribing doctor to determine the safest approach for you.
- Always tell us about all prescription drugs, over-the-counter medicines, and supplements you take
- Tell us if you take tamsulosin (Flomax) or similar prostate or urinary medications, as they can affect the iris during surgery
- Do not stop any medication without your prescribing doctor and surgeon coordinating
- Your eye surgeon will give you specific antibiotic or anti-inflammatory drops to start before surgery
Plan to have someone drive you to and from the surgery center, since you will not be able to drive yourself home. Wear comfortable, loose-fitting clothing and leave jewelry and valuables at home. Avoid wearing makeup, lotions, or perfumes on your face and eyes.
You will receive specific fasting instructions from the surgery center based on your anesthesia plan. Commonly, you will be asked not to eat solid food for six to eight hours before your procedure, and clear liquids may be allowed up to two hours before arrival, unless told otherwise. If you have diabetes or take GLP-1 medications, ask for specific guidance about your medications and eating schedule on surgery day. Bring a list of your medications and any paperwork your surgical center requested. Most patients spend only a few hours at the facility before going home the same day.
What to Expect During Cataract Surgery
Cataract surgery is typically performed using a technique called phacoemulsification. We make a tiny incision at the edge of your cornea, then use a small ultrasound probe to break up the cloudy lens into small pieces. These fragments are gently suctioned out of your eye.
Once the cataract is removed, we insert the new intraocular lens through the same small opening. The lens unfolds and settles into place where your natural lens used to be. In most cases, the incision is so small that it seals on its own without stitches.
We usually use numbing eye drops combined with a mild sedative given through an intravenous line. This approach keeps you relaxed and comfortable while allowing you to rest quietly during the procedure. Most patients feel little to no pain, but you may feel pressure or brief discomfort. Tell us right away if you feel pain so we can help.
Some patients receive a numbing injection around the eye for deeper anesthesia. General anesthesia, where you are completely asleep, is rare and reserved for special situations such as young children or patients who cannot remain still. We will recommend the safest and most comfortable option for your situation.
The actual surgical procedure typically lasts between 15 and 30 minutes per eye. However, you should plan to spend two to three hours at the surgery center for check-in, preparation, the operation itself, and initial recovery. Most of that time is spent getting ready and resting afterward.
Modern techniques and technology have made cataract surgery very efficient and predictable. Even though the surgery is quick, we take all the time needed to ensure precision and safety for the best possible outcome.
You may see bright lights, colors, or moving shapes during surgery, but everything will appear soft and out of focus. These sensations are completely normal and nothing to worry about. You will not see the instruments or any details of what we are doing.
- You may feel gentle pressure or a sensation of water on your eye
- You should not feel sharp pain, though some tugging or coolness is normal
- If you experience discomfort, tell the surgical team right away so we can help
Recovering After Cataract Surgery
Right after surgery, your eye may feel scratchy, irritated, or slightly sore. Your vision will be blurry at first, and you might notice some redness or light sensitivity. These symptoms are expected and usually improve quickly over the first day or two.
We may place a protective shield over your eye, which you should wear while sleeping for the first several nights to a week, per your surgeon's instructions. Avoid rubbing or pressing on your eye, and do not bend over or lift anything heavy during the first 24 hours. Rest is important, but you can resume light activities like watching television or using your phone as comfort allows. Do not drive on surgery day. You may resume driving only when your surgeon confirms it is safe and you meet legal vision requirements.
You will be given prescription eye drops to prevent infection and reduce inflammation. It is very important to use these drops exactly as directed, even if your eye feels fine. Skipping doses or stopping too early can increase your risk of complications.
- Wash your hands thoroughly before touching the bottle or your eye area
- Tilt your head back and pull down your lower eyelid to create a small pocket
- Squeeze one drop into the pocket without letting the tip touch your eye or eyelid
- Close your eye gently for a minute and dab away any extra liquid with a clean tissue
- Wait at least five minutes between different types of drops if you use more than one
For the first week or so, avoid swimming, hot tubs, and getting water directly in your eye while showering. You can shower and wash your hair, but keep your face tilted away from the spray and avoid soap and shampoo running into your operated eye for about a week or as your surgeon directs.
Do not engage in strenuous exercise, heavy lifting, or straining as directed by your surgeon, commonly for at least one week. Avoid activities that could jar your head or risk an eye injury. Skip dusty or dirty environments, and avoid wearing eye makeup until your doctor says it is safe. Most people can return to desk work and normal daily routines within a few days.
Many patients notice clearer vision within a day or two after surgery, but full healing takes several weeks. Your vision may fluctuate during this time as your eye adjusts to the new lens and any swelling goes down. Colors often appear brighter and more vivid once the cloudy cataract is gone.
If you need new glasses, we usually wait at least four to six weeks after surgery to write a final prescription. This allows your eye to heal completely and your vision to stabilize. Until then, your old glasses may work reasonably well, or we can provide a temporary prescription if needed.
Your first follow-up visit is usually scheduled for the day after surgery. We check your vision, measure eye pressure, and look for any signs of infection or inflammation. Additional appointments are typically set for one week and one month after the procedure.
At each visit, we evaluate how well your eye is healing, whether your vision is improving as expected, and if your eye drops are working properly. These appointments are crucial for catching any problems early and ensuring the best long-term results. Always keep your scheduled follow-ups even if your eye feels great.
Potential Risks and Complications
Most patients experience some minor irritation or discomfort after cataract surgery. Mild redness, a gritty feeling, or light sensitivity are very common and typically resolve within a few days. You might also notice some watering or mild discharge from the eye.
Dry eye symptoms can occur or worsen temporarily after surgery. Using lubricating eye drops as directed usually provides relief. Some people see floaters, small spots or cobwebs drifting in their vision, which are often more noticeable after the cataract is removed. Stable, occasional floaters are usually benign, but a sudden increase in floaters, new flashes of light, or a curtain or shadow in your vision requires urgent evaluation as described in the warning signs section below.
Although cataract surgery is very safe, serious complications can occur in rare cases. Infection inside the eye, called endophthalmitis, is extremely uncommon but requires urgent treatment with antibiotics. Retinal detachment, bleeding inside the eye, or significant swelling are other rare events that need immediate attention.
Other possible complications include the following, though most are uncommon and many can be managed if they occur:
- Posterior capsular rupture during surgery, which may require additional steps or a second procedure to address retained lens fragments
- Cystoid macular edema, a swelling in the central retina that can temporarily blur vision
- Elevated eye pressure spikes after surgery, which can be a concern for patients with glaucoma
- Intraocular lens tilt, decentration, or dislocation that may affect vision quality
- Corneal swelling or endothelial cell loss, with higher risk in patients with preexisting corneal conditions such as Fuchs dystrophy
- Dysphotopsias such as glare, halos, starbursts, or shadows, especially with multifocal or extended depth of focus lenses
- Refractive surprise or residual astigmatism requiring glasses or possible laser vision correction afterward
A condition called posterior capsule opacification can develop months or years after surgery, causing vision to become cloudy again. This is not a true cataract returning, but rather clouding of the membrane that holds your new lens. We can treat it with a quick laser procedure in the office, usually with minimal discomfort. The laser carries small risks including temporary pressure rise, inflammation, floaters, or rarely retinal detachment, and you should follow post-laser instructions carefully.
Contact our office right away if you notice sudden vision loss, severe pain that does not improve with over-the-counter pain relievers, or a significant increase in redness or swelling. Worsening light sensitivity combined with decreasing vision can be a warning sign of infection. These symptoms could signal a complication that needs prompt evaluation and treatment.
- A sudden increase in floaters or flashes of light
- A curtain or shadow moving across your field of vision
- Discharge that is thick, yellow, or green
- Nausea or vomiting along with eye pain
If you experience any of these warning signs after hours, contact the on-call ophthalmologist or surgeon immediately, or go to the emergency department. Do not wait until the next business day for urgent symptoms such as sudden vision loss, severe pain, or signs of retinal detachment.
We take many steps to keep your surgery as safe as possible. All instruments are sterile, and we may use antibiotics before, during, or after the procedure per our surgical protocol to help prevent infection. Advanced imaging and surgical technology allow us to plan and perform each step with great precision.
We carefully review your medical history and current medications to identify any factors that might increase risk. Our surgical team monitors you closely throughout the procedure and recovery period. Choosing an experienced surgeon and following all pre- and post-operative instructions also plays a major role in achieving a successful outcome.
Frequently Asked Questions
It depends on the type of intraocular lens you choose and your vision goals. Standard monofocal lenses correct distance vision well, but you will likely need reading glasses for close work. Premium multifocal or extended depth of focus lenses can reduce dependence on glasses for many activities, though they may cause increased halos or glare at night. Some patients still prefer glasses for certain tasks like prolonged reading or night driving. Your surgeon will help you choose the option that best fits your visual needs and eye health.
In the United States, we typically perform cataract surgery on one eye at a time, with the second eye done a few days to a few weeks later. This approach allows the first eye to heal and reduces the small risk of complications affecting both eyes at once. Immediate sequential bilateral cataract surgery, where both eyes are treated on the same day, may be considered in specific cases but is not the current standard in 2025 for most patients.
Most health insurance plans, including Medicare, cover medically necessary cataract surgery and a standard monofocal intraocular lens. If you choose a premium lens or additional refractive procedures to reduce your need for glasses, you may have extra out-of-pocket costs for those upgrades. Our office can help you understand your benefits and any expenses you may be responsible for before your surgery.
Once a cataract is removed, it cannot return because the natural lens has been replaced with an artificial one. However, the thin capsule that holds your new lens in place can become cloudy over time, a condition called posterior capsule opacification. If this happens, we can restore clear vision with a laser treatment in the office, usually quick and with minimal discomfort. The procedure carries small risks including temporary pressure rise and inflammation, and you should follow post-laser care instructions.
Intraocular lenses are designed to be permanent and typically last for the rest of your life. They do not wear out or need to be replaced under normal circumstances. The materials used in modern lenses are very durable and stable, so once your eye heals from surgery, your new lens should provide clear vision for many years. In uncommon situations, a lens may need repositioning or exchange due to dislocation, refractive surprise, intolerance, or complications, but this is rare.
