Understanding What Cataract Surgery Entails

This article was updated in June 2026.

Cataract surgery is the most commonly performed surgical procedure in the United States, and for good reason. It is safe, predictable, and remarkably effective. But if you have never had it done, the idea of surgery on your eye can feel intimidating, and the unknown is often the hardest part.

This guide walks you through everything that happens before, during, and after cataract surgery so that you can approach the experience with clarity and confidence.

Before Surgery: The Pre-Operative Evaluation

Cataract surgery begins well before the day of the procedure. Once you and your eye doctor have decided that surgery is the right step, you will be scheduled for a pre-operative evaluation. This appointment is detailed and important.

During the pre-op exam, your surgeon will:

Measure the precise dimensions of your eye, including the length of the eyeball and the curvature of the cornea, using a process called biometry
Use those measurements to calculate the correct power for your replacement lens
Evaluate the overall health of your retina, cornea, and optic nerve
Review your medical history, current medications, and any conditions that may affect surgery or recovery
Discuss your vision goals and help you choose the right intraocular lens (IOL) for your lifestyle

This is also the appointment to ask every question you have. Your surgical team wants you to feel fully prepared.

In the days before surgery, you will likely receive instructions to:

Use prescription antibiotic and anti-inflammatory eye drops starting one to three days before the procedure
Avoid eating or drinking for several hours before surgery if sedation is being used
Arrange for a driver, as you will not be able to drive yourself home

Choosing Your Replacement Lens

One of the most consequential decisions in cataract surgery happens before you ever set foot in the operating suite: choosing your intraocular lens.

The IOL replaces your eye’s natural lens permanently, so selecting the right type is worth a thoughtful conversation with your doctor. The main categories are:

Monofocal IOLs are the most common and are typically covered by insurance. They are set to correct vision at one distance, usually far. Most patients who choose monofocal lenses will still need reading glasses for close tasks after surgery.
Multifocal and trifocal IOLs are designed to provide a range of vision from near to far, reducing or eliminating the need for glasses after surgery. They involve an additional out-of-pocket cost beyond what insurance covers and are not the right fit for every patient, particularly those with certain retinal conditions.
Toric IOLs are designed specifically for patients with astigmatism. They correct the uneven curvature of the cornea at the same time as the cataract is removed, which can significantly reduce the need for glasses afterward.
Extended depth-of-focus (EDOF) IOLs offer a continuous range of vision with fewer of the glare and halo side effects that some multifocal lenses can produce.

Your eye doctor will help you weigh these options against your daily vision demands, your eye health, and your budget. There is no universally “best” lens, only the best lens for you.

The Day of Surgery: What to Expect Step by Step

Cataract surgery is an outpatient procedure, meaning you arrive, have the surgery, and go home the same day. The entire visit, including preparation and recovery time at the facility, typically lasts two to three hours, though the surgery itself is much shorter.

Here is what the day looks like from arrival to discharge.

Step 1: Arrival and preparation

When you arrive, staff will review your paperwork, confirm your medications, and begin preparing your eye. Dilating drops will be applied to widen the pupil, and anesthetic drops will numb the surface of the eye. You may also receive a mild oral or intravenous sedative to help you relax. You will be awake during the procedure, but you will feel calm and comfortable.

Step 2: Positioning

You will be lying down on a reclining surgical chair beneath a large microscope. The area around your eye will be cleaned and draped. A small device gently holds your eyelid open so you do not need to worry about blinking at the wrong moment.

Step 3: Creating the incision

Your surgeon makes a very small, self-sealing incision, typically less than 3 millimeters wide, at the edge of the cornea. In many cases, a laser is used to create this incision with exceptional precision. This laser-assisted approach, sometimes called laser-assisted cataract surgery (LACS), can also be used to soften the cataract and correct astigmatism before the ultrasound step begins.

Step 4: Removing the clouded lens

Using a technique called phacoemulsification, your surgeon inserts a small ultrasound probe through the incision. The probe emits ultrasonic vibrations that break the clouded lens into tiny fragments, which are then gently suctioned out of the eye. The thin membrane surrounding the lens, called the lens capsule, is intentionally left in place to support the new IOL.

Step 5: Inserting the IOL

The replacement lens, which is folded like a soft taco, is inserted through the same small incision and guided into position within the lens capsule. Once inside the eye, it unfolds and settles into place. No stitches are typically required because the incision is self-sealing.

Step 6: Completion and recovery

The whole surgical procedure generally takes between 15 and 30 minutes. Afterward, you will rest briefly in a recovery area while the clinical team monitors you. A protective shield will be placed over your eye, and you will receive detailed aftercare instructions before being discharged.

After Surgery: Recovery and What to Expect

Recovery from cataract surgery is typically smooth, but it does require some care and patience in the first few weeks.

The first 24 hours. Your vision may be blurry or hazy immediately after surgery as your eye begins to adjust to the new lens. Some patients notice improved vision within hours. Others take a day or two. You may experience mild discomfort, a gritty sensation, light sensitivity, or watery eyes. These effects are normal and usually resolve quickly.

The first week. Most patients return to light daily activities within a day or two of surgery. Driving is typically permitted once your surgeon confirms your vision meets the necessary standard, which often happens at your one-day post-operative appointment. You will be using prescription eye drops multiple times daily during this period.

Activity guidelines during recovery generally include:

Avoiding rubbing or pressing on the eye
Keeping water, soap, and shampoo out of the eye for at least one week
Wearing a protective eye shield while sleeping for the first week
Avoiding strenuous exercise, heavy lifting, and swimming for two to four weeks
Wearing sunglasses outdoors to protect the healing eye from UV light and glare

Follow-up appointments. You will typically be seen the day after surgery, then again at one week and one month. These visits allow your surgeon to confirm that healing is progressing well and to catch any issues early.

Full stabilization. Complete visual stabilization takes four to six weeks. Your final glasses prescription, if one is needed, should not be written until your vision has fully settled.

Potential Risks and Complications

Cataract surgery is very safe, but no surgical procedure is entirely without risk. Being informed about potential complications is part of making a confident decision.

Complications are uncommon, but may include:

Posterior capsule opacification (PCO): The most common post-surgical issue, PCO occurs when the membrane behind the IOL becomes cloudy weeks, months, or years after surgery. It is not a recurrence of the cataract. It is corrected quickly and painlessly in-office with a brief laser procedure called a YAG capsulotomy.
Infection (endophthalmitis): Rare but serious. The risk is minimized by the antibiotic drops prescribed before and after surgery. Any sudden increase in pain, redness, or vision loss after surgery warrants an immediate call to your eye doctor.
Swelling of the retina (cystoid macular edema): Occasional post-surgical inflammation can cause temporary fluid accumulation at the center of the retina. It typically responds well to anti-inflammatory drops.
Elevated eye pressure: Some patients experience a temporary spike in eye pressure after surgery. Your doctor will monitor for this at follow-up visits.
IOL dislocation: Rarely, the replacement lens can shift out of position and may require repositioning.

The vast majority of patients experience none of these complications and go on to enjoy clear, comfortable vision following surgery.

What About the Second Eye?

If both eyes have cataracts, surgery is almost always performed on one eye at a time. A common interval is one to four weeks between procedures, giving the first eye time to heal and your visual system time to adjust before the second surgery.

Many patients find that after the first eye is treated, the difference between the two eyes is immediately noticeable. That contrast is a powerful reminder of how much clearer vision can be.

A Procedure Worth Understanding

Cataract surgery is not something to fear. It is brief, well-tolerated, performed under comfortable sedation, and associated with outcomes that patients consistently describe as life-changing. Colors become vivid again, night driving becomes safer, and the fog that has been gradually settling over daily life begins to lift.

The more you understand about what the procedure involves, the easier it is to approach it with the calm confidence it deserves.

Frequently Asked Questions About Cataract Surgery

Will I be awake during cataract surgery?

Yes, but you will be relaxed and comfortable. Local anesthetic drops numb the eye completely, and most patients receive a mild sedative to ease anxiety. You will not feel pain during the procedure. Many patients report being surprised by how calm and quick the experience was.

How long will the new lens last?

Intraocular lenses are designed to last a lifetime. They do not degrade, expire, or need to be replaced. Once your IOL is in place and healing is complete, it requires no maintenance.

Can I wear my old glasses after cataract surgery?

Your old prescription will likely no longer be accurate after surgery. Most patients need an updated glasses prescription, if they need glasses at all, and this is written once vision has fully stabilized at the four-to-six-week mark.

What if I have other eye conditions as well as cataracts?

Conditions such as glaucoma, macular degeneration, or diabetic retinopathy can affect both the surgical approach and the expected outcome. Your surgeon will evaluate these conditions carefully during your pre-operative exam. In some cases, combined procedures or additional monitoring are recommended. Having other eye conditions does not automatically disqualify you from cataract surgery.
