Cataract Surgery: Procedure, Recovery, and Rehabilitation

Medically reviewed by the Know Your Surgery Editorial Team. Last reviewed: May 2026.

Once the decision to proceed with cataract surgery has been made, most patients want to know exactly what to expect on the day of surgery and during recovery. Cataract surgery in the United States is highly standardized, and the patient experience is consistent across most surgical centers. This article walks through preparation, the procedure step by step, anesthesia, the second-eye approach, and what recovery typically looks like week by week.

If you have not yet read about why surgery may be recommended, our causes, diagnosis, and decision article covers how the decision is made.

Preparing for Cataract Surgery

In the days leading up to surgery, the patient receives specific instructions from the surgical team. These usually include:

• Eye drops prescribed in the days before surgery, often an antibiotic, an anti-inflammatory, or both. These help prevent infection and inflammation.
• Medication review. The team checks current medications and may ask the patient to temporarily pause specific drugs, such as alpha-blockers prescribed for the prostate, that can affect the iris during surgery.
• Fasting instructions if light sedation is planned. Many surgical centers ask patients to avoid food and drink for several hours before surgery.
• Transportation arrangements. Patients should plan to have someone drive them home, as the operated eye will be shielded and vision in the eye will not be reliable for driving immediately after the procedure.
• Comfortable clothing. Loose, button-front clothing makes it easier to change for surgery and keeps the operated eye area clean afterward.

The pre-surgical measurements that determine the artificial lens (intraocular lens, or IOL) selection have usually been completed at an earlier appointment. Patients arrive at the surgical center the morning of surgery with the IOL choice already made.

The Phacoemulsification Procedure Step by Step

Most cataract surgery in the United States uses a technique called phacoemulsification, often shortened to phaco. The full procedure usually takes 15 to 30 minutes per eye, although patients are at the surgical center longer for check-in, preparation, and recovery monitoring.

The general sequence inside the operating room is:

1. Numbing eye drops are placed in the eye to block sensation. A mild intravenous sedative may be given to help the patient relax. The patient is awake but comfortable and instructed to look straight ahead.
2. Skin around the eye is cleaned with antiseptic, and a small drape is placed to keep the area sterile. A tiny lid holder gently keeps the eyelids open so the patient does not have to focus on holding the eye open.
3. A small corneal incision of just a few millimeters is made at the edge of the cornea. The opening is small enough that it usually heals without stitches.
4. A circular opening, or capsulorhexis, is created in the front of the lens capsule. The lens capsule is the thin membrane that holds the natural lens and will later hold the new IOL.
5. An ultrasound probe is gently inserted through the corneal incision, and high-frequency vibrations break up the cloudy lens material into tiny fragments. This is the phacoemulsification step that gives the procedure its name.
6. The fragments are suctioned out of the eye through the same probe.
7. The folded artificial IOL is inserted through the small corneal incision. It unfolds inside the lens capsule and settles into its permanent position.
8. The eye is rinsed gently to remove any residual fluid, and the corneal incision is checked. The protective shield is placed over the operated eye, and the patient is moved to a recovery area.

During the procedure, the patient typically sees only bright lights and movement. There is no pain. Many patients report that the operation is shorter than they expected.

Femtosecond Laser-Assisted Cataract Surgery (FLACS)

A subset of US cataract surgeries uses a femtosecond laser to perform some of the early steps of the procedure. The laser can create the corneal incision, perform the capsulorhexis, and pre-soften the lens before the surgeon completes the procedure manually.

The decision to use femtosecond laser-assisted cataract surgery (FLACS) is made between the patient and surgeon based on the patient’s eye, the surgeon’s training, and personal preference. Both traditional phacoemulsification and FLACS have well-established safety records.

Anesthesia for Cataract Surgery

The standard anesthesia for cataract surgery in the United States is topical anesthetic eye drops. These numb the surface of the eye and surrounding tissues without affecting consciousness.

A light intravenous sedative may be added to help patients who are anxious. General anesthesia, which puts the patient fully to sleep, is rarely used and is reserved for unusual circumstances such as patients who cannot lie still or follow instructions during the procedure.

Patients can usually communicate with the surgical team throughout the procedure if needed.

The Second-Eye Approach

For patients who need cataract surgery in both eyes, US ophthalmologists generally schedule the surgeries separately. The first eye is operated on, and the second eye is typically scheduled one to four weeks later, after the first eye has stabilized and any IOL adjustments are well understood.

This staged approach allows the patient and surgeon to evaluate the result of the first eye and refine the plan for the second if needed. It also reduces the risk of any complication affecting both eyes simultaneously.

What Happens Right After Surgery

Immediately after the procedure, the patient rests in a recovery area for a short time, often 30 to 60 minutes. Vision through the operated eye is usually blurry, hazy, or distorted in the first few hours. This is normal and improves quickly. The protective eye shield is kept in place to prevent accidental rubbing or pressure on the eye.

Most patients are sent home the same day with detailed written instructions, eye drop prescriptions, and a follow-up appointment scheduled for the next day.

Recovery Timeline Week by Week

Recovery is typically smooth and predictable, but patience is important. The eye continues to heal for several weeks even after vision improves.

Day 1 after surgery. The patient sees the surgeon for a brief examination. The protective shield is removed for inspection and replaced for sleep over the next several nights. Many patients notice clearer vision already, though some haziness, light sensitivity, or mild scratchy sensation is normal.

Week 1. Most patients can resume light daily activities such as reading, watching television, gentle walking, and household tasks. Eye drops are used multiple times per day on a tapering schedule. Patients should avoid bending below the waist for prolonged periods, lifting heavy objects, swimming, hot tubs, and rubbing the eye. The eye shield is typically used at night during sleep for the first week or so.

Weeks 2 to 4. Most activity restrictions ease. Many patients return to driving once the surgeon confirms vision and depth perception are adequate, often after the first follow-up. Patients begin to notice clearer, brighter colors as the brain adjusts to the new lens.

Month 1 to month 3. The eye fully stabilizes, and final glasses prescriptions can be measured if needed. Patients with monofocal IOLs typically pick up reading glasses at this stage. Patients with multifocal or extended depth-of-focus IOLs may need a few months to fully adapt to the new visual experience.

These timelines are general. Individual recovery varies based on age, overall eye health, the specific IOL chosen, and any complications. Always follow your specific surgeon’s instructions, which may differ from these general guidelines.

The Post-Operative Eye Drop Regimen

Eye drops are central to recovery. Most patients are prescribed two or three different drops, typically including:

• An antibiotic drop to prevent infection
• An anti-inflammatory steroid drop to reduce inflammation
• A non-steroidal anti-inflammatory drop, which may also help reduce inflammation and swelling

The drops are used multiple times per day on a tapering schedule that usually extends three to four weeks after surgery. Following the schedule precisely is important. Skipping doses or stopping early can increase the risk of inflammation or infection.

A simple way to keep track is a written or printed schedule on the refrigerator, with checkboxes for each dose. Some pharmacies also provide pre-printed schedules.

Activity Restrictions and Common-Sense Care

In the early weeks after surgery, the eye is more vulnerable than usual. Common restrictions include:

• No rubbing or pressing on the operated eye
• No swimming, hot tubs, or fully submerging the head in water for the period your surgeon specifies
• Limit heavy lifting, generally above 10 to 15 pounds, for the first one to two weeks
• Avoid bending at the waist for prolonged periods
• Wear sunglasses outdoors for the first few weeks to reduce light sensitivity
• Avoid eye makeup until your surgeon says it is safe

Driving usually resumes once the surgeon confirms vision and depth perception are adequate. For patients having both eyes operated on, this is often after the second eye has been treated.

Follow-Up Appointments

A typical follow-up schedule includes:

• Day after surgery for the first check
• One week after surgery
• Three to four weeks after surgery
• Additional visits as needed to refine glasses prescription or address any concerns

If both eyes need surgery, the second-eye procedure is often scheduled around the time of the second or third follow-up of the first eye. Patient questions about specific recovery situations are addressed in detail in our FAQs and statistics article.

Rehabilitation and Long-Term Outlook

Most patients enjoy a steady improvement in vision over the weeks following surgery. The brain adapts quickly to the new lens, especially in patients who had significant cataracts before surgery. Restored vision often translates into easier reading, safer driving, more confidence at home, and renewed enjoyment of hobbies and outdoor activities.

In the long term, the artificial lens itself does not cloud or wear out. A small percentage of patients may experience clouding of the back portion of the lens capsule months or years later. This is called posterior capsule opacification and is treated quickly and painlessly with a brief in-office laser procedure. We cover that and other long-term questions in our FAQs and statistics article.
