Cataract Surgery FAQs
Understanding Cataracts and When Surgery Is Needed
A cataract is a clouding of the eye's natural lens, and understanding what it is helps you recognize when it is affecting your life enough to take action. Knowing the warning signs and risk factors helps you and your Cataract Surgeon make the right decision together.
The natural lens inside your eye sits just behind your pupil and focuses light onto the retina at the back of your eye. When proteins inside that lens begin to clump together over time, the lens turns cloudy and blocks or scatters incoming light. The result is blurry, hazy, or dim vision that glasses alone cannot fully correct.
Most cataracts develop slowly as part of the normal aging process. You may notice that colors appear washed out or yellowed, that halos form around lights at night, or that reading becomes harder even with an updated prescription.
We recommend surgery when a cataract begins to interfere with daily life and safety. Common signs include difficulty driving at night, trouble reading standard print, and problems with hobbies that require clear, detailed vision.
- Frequent changes in your eyeglass or contact lens prescription
- Double vision in one eye
- Difficulty seeing in bright sunlight or with glare from headlights
- Colors appearing faded or yellowed
- Trouble with activities like sewing, golf, or watching television
In some cases, we may recommend surgery for medical reasons even when symptoms are mild. These include cataracts that are raising eye pressure, narrowing the drainage angle, or blocking the view needed to examine and treat the retina.
Not every cataract needs immediate surgery. In the early stages, updating your glasses or using brighter lighting may be enough to manage your symptoms comfortably. We often suggest a period of monitoring when vision changes are mild and do not affect your safety or quality of life.
Surgery becomes the better choice when vision loss limits what you want or need to do each day. The decision is personal and reflects your lifestyle, visual demands, and overall health. Your Cataract Surgeon will discuss the timing that makes the most sense for your situation.
Aging is the leading risk factor, with most cataracts appearing after age 60. Several other factors can cause cataracts to form earlier or progress more quickly.
- Diabetes and other metabolic conditions
- Long-term use of corticosteroid medications
- Previous eye injury or chronic eye inflammation
- Extended exposure to ultraviolet light without proper eye protection
- Smoking and excessive alcohol use
Preparing for Cataract Surgery
Good preparation makes surgery smoother and helps set realistic expectations for your recovery and outcome. Your Cataract Surgeon will guide you through each step, from pre-surgical measurements to choosing the right lens and planning for surgery day.
Before surgery, we perform a thorough eye evaluation to measure the size and shape of your eye. These measurements are used to calculate the correct power and type of intraocular lens (IOL) for your eye. We also check for other eye conditions such as dry eye, macular disease, or corneal irregularities that could affect your surgery or recovery.
You can expect tests that include pupil dilation, corneal curvature mapping, and ultrasound or optical imaging to evaluate the interior of your eye. This appointment typically takes about an hour, and you should bring someone to drive you home since the dilating drops will blur your vision.
During cataract surgery, your cloudy natural lens is replaced with a clear artificial lens called an intraocular lens, or IOL. The lens you choose will influence how you see after surgery, including whether you need reading glasses for everyday tasks.
Standard monofocal lenses provide clear vision at one distance, typically far away, and most patients will still need reading glasses. Some patients choose a monovision approach with monofocal lenses, where one eye is set for distance and the other for near, to reduce overall dependence on glasses. Premium options include toric lenses that correct astigmatism, multifocal lenses designed to provide a range of focus, and extended depth of focus lenses that aim to broaden clear vision. Premium multifocal and extended depth of focus lenses can increase halos and glare, particularly at night, and may not be appropriate for all eyes, including those with dry eye, macular disease, or irregular astigmatism. Your Cataract Surgeon will review which lens best matches your vision goals, lifestyle, and eye health.
Most regular medications can continue right up to the day of surgery. Blood thinners are often continued for cataract surgery, though some cases require adjustment in coordination with your prescribing doctor. Always inform us about every prescription drug, over-the-counter medicine, and supplement you take.
- Tell us if you take tamsulosin (Flomax) or similar prostate or urinary medications, as these can affect the iris during surgery
- Do not stop any medication without your surgeon and prescribing doctor coordinating first
- Your Cataract Surgeon will provide specific antibiotic and anti-inflammatory drops to begin before surgery
Plan to have a responsible adult drive you to and from the surgical facility, 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 around your eyes.
You will receive specific fasting instructions from the surgery center based on your anesthesia plan. In general, you will be asked to avoid solid food for six to eight hours before the procedure, and clear liquids may be permitted up to two hours before arrival unless instructed otherwise. If you have diabetes or take GLP-1 medications, ask for specific guidance about your eating schedule and medications on surgery day. Bring a list of all your medications and any paperwork the surgical center has requested. Most patients spend only a few hours at the facility before going home the same day.
What Happens During Cataract Surgery
Understanding the procedure itself can ease anxiety and help you feel more comfortable on surgery day. Modern cataract surgery is efficient, precise, and typically takes far less time than most patients expect.
We most commonly perform cataract surgery using a technique called phacoemulsification. We make a very small incision at the edge of your cornea, then use a tiny ultrasound probe to break the cloudy lens into small pieces, which are gently suctioned out of the eye. The new intraocular lens is then inserted through that same small opening, where it unfolds and settles into place.
In many cases the incision is so small that it seals on its own without stitches. Femtosecond laser-assisted cataract surgery is another option available at our practice that uses a laser to perform certain steps with additional precision, including the initial incision, lens fragmentation, and astigmatism correction.
We typically use numbing eye drops combined with a mild sedative given through an intravenous line to keep you relaxed and comfortable. Most patients feel little to no pain during the procedure, though you may feel gentle pressure or brief coolness. Tell us right away if you feel pain so we can respond immediately.
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. Your Cataract Surgeon will recommend the safest and most comfortable option for your specific needs.
The surgical procedure itself typically lasts between 15 and 30 minutes per eye. However, you should plan to spend two to three hours at the surgical facility to account for check-in, preparation, the operation, and initial recovery.
Even though the surgery is brief, we take all the time needed to ensure precision and safety at every step. Preparation and careful monitoring before and after are just as important as the procedure itself.
During surgery, you may see bright lights, shifting colors, or soft shapes. These sensations are completely normal and are nothing to worry about. You will not see instruments or have a detailed view of what is happening.
- You may feel gentle pressure or a sensation of water on your eye
- You should not feel sharp pain, though mild tugging or coolness is normal
- If you experience discomfort at any point, let the surgical team know immediately
Recovering After Cataract Surgery
Recovery from cataract surgery is generally straightforward, but following your instructions closely helps protect your result and reduces the risk of complications. Most people return to light daily activities within a few days, with full healing taking several weeks.
Right after surgery, your eye may feel scratchy, irritated, or mildly sore. Vision will be blurry at first, and you may notice some redness or light sensitivity. These effects are expected and typically improve quickly within 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 as directed by your surgeon. 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 a phone as comfort allows. Do not drive on surgery day, and only resume driving after your surgeon confirms it is safe and you meet your state's legal vision requirements.
You will receive prescription eye drops to prevent infection and reduce inflammation after surgery. Using them exactly as directed is essential, even if your eye feels completely fine. Stopping early or skipping doses can raise the risk of complications.
- Wash your hands thoroughly before handling the bottle or touching the area around your eye
- Tilt your head back, pull down your lower eyelid, and place one drop into the small pocket formed
- Avoid letting the dropper tip touch your eye or eyelid
- Close your eye gently for about one minute and dab away any excess with a clean tissue
- Wait at least five minutes between different types of drops if you are using 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 tilt your face away from the spray and keep soap and shampoo out of the operated eye for about one week or as your surgeon advises.
Avoid strenuous exercise, heavy lifting, and straining as directed by your surgeon, generally for at least one week. Skip dusty or dirty environments and avoid wearing eye makeup until your doctor confirms it is safe. Most patients can return to desk work and routine daily activities within a few days.
Many patients notice meaningfully clearer vision within one to two days of surgery, but full healing takes several weeks. Your vision may fluctuate during this time as your eye adjusts to the new lens and any residual swelling resolves. Colors often appear brighter and more vivid once the cataract is gone.
If you need new glasses, we typically wait at least four to six weeks after surgery before writing a final prescription. This allows the eye to heal completely and vision to stabilize. In the meantime, your prior glasses may work reasonably well for many activities, or we can provide a temporary prescription if needed.
Your first follow-up visit is usually the day after surgery. We check your vision, measure eye pressure, and look for any signs of infection or inflammation. Additional visits are typically scheduled at one week and one month after the procedure.
At each appointment, we assess how your eye is healing, whether vision is improving as expected, and whether your eye drops are working properly. These visits are important for catching any issues early and ensuring the best long-term outcome. Please keep all scheduled follow-ups, even if your eye feels great.
Potential Risks and Complications
Cataract surgery is one of the safest surgical procedures performed today, but no surgery is completely without risk. Understanding what to watch for and when to seek help is an important part of your care.
Most patients experience some minor irritation after surgery. Mild redness, a gritty sensation, light sensitivity, and slight watering are very common and typically resolve within a few days. Dry eye symptoms can also occur or temporarily worsen, and lubricating eye drops usually provide relief.
Some patients notice floaters, which are small spots or cobwebs drifting through vision. Floaters can be more noticeable once the cataract is removed and the view through your eye is clearer. Stable, occasional floaters are generally benign, but a sudden increase in floaters, new flashes of light, or a curtain or shadow across your vision requires urgent evaluation.
Although serious complications are uncommon, it is important to know they can occur. Infection inside the eye, called endophthalmitis, is extremely rare but requires urgent treatment. Retinal detachment, bleeding inside the eye, or significant swelling are other rare events that require immediate attention.
Other possible complications include the following, though most are uncommon and many can be managed when caught early.
- 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, particularly a concern for patients with glaucoma
- Intraocular lens tilt, decentration, or dislocation affecting vision quality
- Corneal swelling or endothelial cell loss, with higher risk in patients with preexisting corneal conditions such as Fuchs dystrophy
- Dysphotopsias including glare, halos, starbursts, or shadows, especially with multifocal or extended depth of focus lenses
- Residual refractive error or 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 cataract returning. Rather, it is clouding of the thin membrane that holds the new lens in place. We can treat it with a quick, in-office laser procedure that is usually well tolerated, though it carries small risks including a temporary rise in eye pressure, inflammation, floaters, or rarely retinal detachment.
Contact us right away if you notice sudden vision loss, severe eye pain that does not ease with over-the-counter pain relief, or significant worsening of redness or swelling. Increasing light sensitivity paired with decreasing vision can signal infection. These symptoms need prompt evaluation and should not be waited out.
- A sudden increase in floaters or new flashes of light
- A curtain or shadow moving across your field of vision
- Thick, yellow, or green discharge from the eye
- Nausea or vomiting combined with eye pain
If any of these symptoms develop after hours, contact the on-call 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 any signs of retinal detachment.
Our Cataract Surgeons take every precaution to keep your surgery as safe as possible. All instruments are sterile, and we follow strict antiseptic and antibiotic protocols before, during, and after surgery to help prevent infection. Advanced imaging and surgical technology allow us to plan each procedure with precision tailored to your eye.
We carefully review your complete medical history and all medications to identify factors that could increase risk. Our surgical team monitors you closely throughout the procedure and recovery. Fellowship-trained surgeons at our practice bring training from institutions including Bascom Palmer, Wilmer Eye Institute at Johns Hopkins, Baylor, Yale, the University of Minnesota, and Manhattan Eye, Ear and Throat, so complex cases are handled with the depth of expertise they require.
Frequently Asked Questions
These answers address practical questions and situations that come up most often when patients are preparing for or recovering from cataract surgery.
The honest answer depends on the type of intraocular lens you choose and your personal vision goals. If you select a standard monofocal lens, you will likely do well at distance but will need reading glasses for close work. Premium lenses such as multifocal or extended depth of focus designs are intended to reduce your dependence on glasses across a range of distances, but they can increase halos and glare at night and are not appropriate for every eye. If you have significant dry eye, macular changes, or irregular astigmatism, a simpler lens may actually serve you better overall. Your Cataract Surgeon will walk you through the trade-offs based on your specific eye health and daily visual needs.
In standard practice, we schedule cataract surgery one eye at a time, with the second eye treated a few days to a few weeks after the first. This staged approach allows the first eye to stabilize and provides important information for planning the second eye's lens selection. It also limits the very small risk of a complication affecting both eyes simultaneously. Performing both eyes on the same day may be considered in certain specific situations, but it is not the standard approach for most patients and involves additional considerations that your surgeon will discuss with you.
Most health insurance plans, including Medicare, cover medically necessary cataract surgery along with a standard monofocal intraocular lens. If you choose a premium lens upgrade such as a toric, multifocal, or extended depth of focus lens, or if additional refractive procedures are performed to reduce your dependence on glasses, there will typically be out-of-pocket costs for those enhancements. The amount varies by plan and by the specific lens or procedure chosen. Our team can help you understand your coverage and any expected expenses well before your surgery date so there are no surprises.
Once the natural lens is removed and replaced with an artificial one, a true cataract cannot return. However, the thin membrane that holds your new lens in place, called the posterior capsule, can gradually become cloudy in the months or years following surgery. This is called posterior capsule opacification, and it can cause your vision to feel hazy again in a way that resembles a cataract. The good news is that it can be treated in the office with a quick, targeted laser procedure called a YAG capsulotomy. The procedure is generally well tolerated, though it carries small risks, and your surgeon will give you specific instructions to follow afterward.
Intraocular lenses are designed to be permanent. Modern lens materials are highly stable and durable, and under normal circumstances a well-positioned IOL will provide clear vision for the rest of your life without needing replacement or adjustment. In uncommon situations, a lens may need to be repositioned or exchanged due to dislocation, a refractive result that does not meet expectations, or intolerance of a premium lens design. These situations are rare, and our surgeons have the subspecialty training to manage complex lens revisions when they are needed.
Having another eye condition does not necessarily prevent you from having cataract surgery, but it does add complexity that requires careful planning. For patients with glaucoma, we can sometimes combine cataract surgery with a minimally invasive glaucoma procedure, called MIGS, to address both conditions at once. For patients with corneal disease such as Fuchs dystrophy or keratoconus, combined procedures may be an option depending on the severity of the condition. Our practice includes Cataract Surgeons who specialize in these complex combined cases, and your entire care plan can be coordinated in-house so no aspect of your eye health is overlooked.
