Cataract surgery is one of the most common and successful surgical procedures performed worldwide. It’s a straightforward operation aimed at restoring vision by removing the clouded lens of the eye and replacing it with a clear artificial lens. If you’re preparing for cataract surgery, you might be wondering about the time it takes and what the entire process entails.

Here’s a comprehensive guide on how long cataract surgery takes and what to expect before, during, and after the procedure.

How long does cataract surgery take?

The actual surgical procedure to remove a cataract typically takes 15 to 30 minutes per eye, depending on the complexity of the case and the surgeon’s technique. While the operation itself is relatively quick, you should expect to spend about 2 to 3 hours at the surgical centre to account for preparation, pre-operative procedures, and recovery time.

If both eyes require surgery, the operations are usually scheduled on different days, often a few weeks apart. This allows one eye to heal before proceeding with the other.

What happens before surgery?

Pre-operative assessment

Before the surgery day, you’ll undergo a thorough evaluation to ensure you’re a suitable candidate. Your ophthalmologist will:

  • Examine the health of your eyes.
  • Measure your eye to determine the appropriate lens implant.
  • Discuss your medical history and any medications you’re taking.

You may also receive instructions on when to stop eating or drinking before the procedure and which medications to take or avoid on surgery day.

Preparation on the day

Upon arrival at the surgical centre, the staff will prepare you for the procedure. This includes:

  • Administering eye drops to dilate your pupil.
  • Using local anaesthetic (often eye drops or an injection) to numb the eye.
  • Giving you a mild sedative to help you relax, though you’ll remain awake during the surgery.

What happens during surgery?

The most common method of cataract surgery is phacoemulsification:

  • A tiny incision is made in the cornea.
  • An ultrasound probe is used to break up the cataract into small fragments.
  • The fragments are removed, and an artificial intraocular lens (IOL) is inserted to replace the clouded natural lens.

The procedure is painless, and you may notice bright lights or slight pressure during the operation. Once complete, the surgeon will cover your eye with a protective shield to keep it safe.

What happens after surgery?

Immediate recovery

After the procedure, you’ll rest in a recovery area for about 30 to 60 minutes. Once the medical team ensures you’re stable, you’ll be discharged, usually on the same day.

Post-surgery care

You’ll receive instructions on using eye drops to prevent infection and reduce inflammation. Most people notice an improvement in their vision within a few days, although it may take a few weeks for your eye to fully heal. Avoid strenuous activities, rubbing your eye, or exposing it to water during the initial recovery phase.

Key information

  • Procedure Time: Cataract surgery typically lasts 15 to 30 minutes.
  • Overall Appointment Duration: Expect to spend about 2 to 3 hours at the surgical centre.
  • Recovery Time: Vision often improves within a few days, but full healing may take up to 6 weeks.

Cataract surgery is a quick, safe, and effective procedure that can dramatically enhance your quality of life. If you’re scheduled for surgery, understanding the timeline and process can help you feel more confident and prepared.

If you have concerns or questions, consult your ophthalmologist, they’ll ensure you know exactly what to expect every step of the way.
