You are awake during cataract surgery, but you will not feel pain or remember much of it

Cataract surgery does not use general anesthesia that puts you to sleep. Instead, your eye surgeon uses local anesthesia — numbing drops and sometimes a small injection around the eye — so you stay awake but cannot feel the procedure. You may receive a mild sedative through an IV to help you relax, but you will not be unconscious.

The numbing is very effective. You will feel pressure and see light and movement, but not pain. Many patients say the hardest part is staying still and keeping their eye open, not discomfort. The whole surgery usually takes 10 to 15 minutes per eye.

Whether you get IV sedation depends on your surgeon, your anxiety level, and your medical history. Some surgeons offer it routinely; others use it only when a patient is very nervous. You and your surgeon will discuss this before the day of surgery.

Key Takeaways

  • Cataract surgery uses numbing drops and local anesthesia around the eye, not general anesthesia that puts you to sleep.
  • You stay awake during the procedure and may feel pressure or see light, but the numbing prevents pain.
  • Some surgeons offer IV sedation to help anxious patients relax, though you will still be conscious.
  • Tell your surgeon before surgery if you are very anxious, have a history of motion sickness, or cannot lie still — these affect whether sedation is recommended.
  • If you take blood thinners or have other medical conditions, your surgeon needs to know before surgery to plan anesthesia safely.

How local anesthesia works during cataract surgery

Your surgeon will place numbing drops in your eye several times in the minutes before surgery. These drops numb the surface. Then, depending on the surgeon's technique, they may inject numbing medication around the eye using a very fine needle — this is called a retrobulbar block or peribulbar block. Some surgeons use only the drops and skip the injection.

The injection itself may sting for a few seconds, but once it takes effect (usually within 5 to 10 minutes), you will not feel the surgery. Your eye will be numb and you will not be able to move it much, which is exactly what the surgeon needs. The numbness lasts several hours after surgery ends.

You will be aware during the procedure — you can hear the surgeon and staff, and you may see light or shadows — but you will have no pain and often very little memory of details. This is normal and expected.

What IV sedation does and does not do

If your surgeon offers IV sedation, it is a mild sedative given through a vein in your arm. Common medications include midazolam or propofol in very low doses. This medication makes you drowsy and relaxed, and it often causes anterograde amnesia — you will not remember much of what happened during surgery, even though you were conscious.

IV sedation is not the same as general anesthesia. You will not be fully asleep, and you will still respond to the surgeon's instructions — for example, if they ask you to look in a certain direction. A nurse or anesthesiologist will monitor your heart rate, blood pressure, and oxygen level throughout.

Not all patients need or want IV sedation. Many do fine with local anesthesia alone and prefer to avoid the extra medication and the recovery time it adds. Talk with your surgeon about whether it is right for you.

Medical conditions and medications that affect anesthesia choices

Tell your surgeon before surgery if you take blood thinners like warfarin, apixaban, or aspirin. Some surgeons may ask you to stop these medications before surgery; others will not. The decision depends on why you take them and the surgeon's preference.

If you have a history of motion sickness, nausea, or anxiety, mention this. These can make the procedure harder, and your surgeon may recommend IV sedation or adjust the anesthesia plan. If you have sleep apnea or other breathing problems, your surgeon needs to know because IV sedation carries different risks for you.

Allergies to medications are also important. Tell your surgeon if you have ever had a bad reaction to any anesthetic or numbing medication. If you are pregnant or think you might be, tell your surgeon before the day of surgery.

What happens in the recovery room after surgery

After surgery, you will move to a recovery area. If you had only local anesthesia with no IV sedation, you may be ready to leave within 30 minutes. Your eye will still be numb, so be careful not to rub it.

If you had IV sedation, you will need to stay longer — usually 1 to 2 hours — while the medication wears off. You will feel drowsy and may not remember the surgery clearly. A staff member will monitor you, and you must have someone drive you home. You cannot drive yourself or operate machinery for the rest of the day.

Your surgeon will give you antibiotic and anti-inflammatory eye drops to use at home. You will have a follow-up appointment the next day. Do not rub your eye, swim, or do strenuous activity for at least a week.

Preparing for anesthesia before your surgery date

Your surgeon's office will send you instructions before surgery. These usually include when to stop eating and drinking (often 6 to 8 hours before surgery) and which medications to take or skip. Follow these carefully — an empty stomach is important for safety if you will have IV sedation.

Wear comfortable, loose clothing on surgery day. Do not wear makeup, nail polish, or jewelry. Bring your insurance card and a list of all medications and supplements you take, including over-the-counter ones. If you take blood pressure medication, ask your surgeon whether to take it the morning of surgery.

Arrange for someone to drive you home. Even if you had only local anesthesia, your vision may be blurry and your eye may be uncomfortable. You should not drive.

Frequently Asked Questions

Will I feel pain during cataract surgery?

No. The numbing drops and local anesthesia prevent pain. You may feel pressure, vibration, or see light and movement, but pain means the anesthesia is not working — tell your surgeon when ready if this happens.

Can I choose to be completely asleep?

General anesthesia is rarely used for cataract surgery because it carries more risk and is not necessary. Local anesthesia with IV sedation (which causes memory loss) is the closest option. Discuss your concerns with your surgeon; they can explain why local anesthesia is standard and whether sedation is right for you.

What if I move my eye during surgery?

The numbing medication paralyzes the eye muscles slightly, making large movements difficult. If you do move, the surgeon is trained to pause and adjust. Tell your surgeon before surgery if you have a tremor, involuntary eye movements, or difficulty staying still.

How long does the numbness last after surgery?

The numbing drops wear off within a few hours. Your eye may feel scratchy or uncomfortable as sensation returns — this is normal. Use the antibiotic drops your surgeon prescribed and avoid rubbing your eye.

Will I remember the surgery if I have IV sedation?

Probably not much. IV sedation causes memory loss, so most patients remember little or nothing of the procedure itself. You will be conscious and able to follow instructions, but the experience will feel like it happened very quickly or not at all.
