How long does cataract surgery take? The operation itself is usually relatively brief, but patients should expect the total visit to take longer because preparation and postoperative monitoring happen before and after the procedure.
Different hospitals describe slightly different operating times. Some NHS eye units describe cataract surgery as taking about 15 to 30 minutes, while the U.S. National Eye Institute notes that the surgery can last about an hour. The exact time depends on the eye, the surgical technique, and the patient’s individual needs.

The Operation Is Only One Part of the Appointment
Patients often focus on the minutes spent in the operating room, but the full cataract-surgery visit includes several stages. Before surgery, staff confirm the patient’s identity and medical information, prepare the eye, administer prescribed drops, and review the surgical plan.
After surgery, the patient spends time in a recovery area while the medical team checks the eye and makes sure there are no immediate problems before discharge.
What Happens During Cataract Surgery?
During cataract surgery, the cloudy natural lens is removed and replaced with an artificial intraocular lens. Many cataract operations are performed using phacoemulsification, in which ultrasound energy breaks the cloudy lens into smaller pieces so it can be removed through a small incision.
The Cataract Surgery in Cuba program describes phacoemulsification as one of the surgical approaches used for cataract treatment, while noting that the exact technique depends on the clinical situation.
Will I Be Awake During the Procedure?
Cataract surgery is commonly performed with local anesthesia. Patients are often awake but the eye is numbed, and medication may be used to help the patient remain relaxed. Patients may notice light or movement but generally cannot see the details of the operation.
The anesthesia plan is individualized. Patients with specific medical conditions, anxiety, or difficulty lying still should discuss this with the surgical team in advance.
How Long Should I Plan to Be at the Surgical Facility?
The total time at the facility is typically longer than the surgery itself. Preparation, waiting, the procedure, and postoperative observation can occupy several hours even when the operation is short.
International patients should avoid scheduling tight travel connections on the day of surgery. A medical team may also require follow-up before the patient is cleared for onward travel.
Does a Longer Operation Mean Something Is Wrong?
Not necessarily. Operating time can vary because of cataract density, the anatomy of the eye, previous eye surgery, pupil size, other eye conditions, or the technique selected by the surgeon.
The surgeon’s priority is a safe and appropriate procedure, not meeting a particular number of minutes.
What Happens Immediately After Surgery?
After the IOL is placed, the eye may be protected with a shield or other covering. The patient is monitored and given instructions about eye drops, protecting the eye, physical activity, follow-up appointments, and symptoms that require urgent attention.
The National Eye Institute advises patients not to drive themselves home after cataract surgery and to arrange transportation.
Planning Cataract Treatment in Cuba
Patients considering cataract treatment abroad should allow enough time for evaluation before surgery and postoperative review afterward. CubaHeal’s ophthalmology programs and cataract surgery program provide information about eye-care pathways in Cuba.
Frequently Asked Questions
Can cataract surgery be finished in 15 minutes?
Some uncomplicated operations may be completed within a short operating window, but patients should not assume the entire appointment will take only 15 minutes.
Do both eyes get operated on at the same time?
Practice varies by surgeon, facility, and patient. Many patients have the eyes treated separately. The appropriate schedule should be decided by the ophthalmologist.
Can I travel immediately after cataract surgery?
Travel plans should be discussed with the treating team. Follow-up, pressure changes during travel, medications, and the patient’s individual eye condition may affect timing.
