You've been told you'll be awake for cataract surgery, and the next thought is the one almost everyone has: am I going to watch them do it?
The short answer is no, and the longer answer is more reassuring than most people expect. The video below is what I'd tell you in the exam room if we had the time to go through all of it. Nine minutes. Watch it before your surgery day, and if you can, watch it with whoever is driving you.
What to listen for
- What awake actually means in that room, and the one easy job you'll have while you're in there.
- What you'll feel, and the one thing you won't.
- A study that asked 102 patients what they saw. Almost all of them named the same thing first, and it isn't an instrument.
- What the colors are, where they come from, and why they move.
- Why your eye can see a bright light but can't see the surgery, in one physical fact.
- The one surprise partway through that stops being a surprise once you know it's coming.
What patients drew afterward
Researchers have asked patients to draw what they saw during their own cataract surgery. Two of those drawings are below, along with a chart of the colors a group of patients reported. Look at them before you watch, then listen for how close the descriptions in the video come.
What didn't make the cut
Every video gets trimmed. Four things came out of this one, and every one of them is on the reassuring side.
Numbing is drops, not a needle. Years ago, numbing an eye for surgery meant an injection behind the eye. Today it's drops. Nothing sharp comes near your eye to get it numb, there's less to recover from, you're home sooner, and your eye keeps working normally the whole time. That last part is why you'll see light during the operation, and the video is about what that light looks like.
Being told what to expect helps reduce anxiety. This has been tested. In one study, patients who watched a short information video before surgery had sharply lower anxiety scores than patients who didn't, and nothing about the operation was different, only what they knew going in. In the video I tell you about a larger trial that found the same thing. And yet it often doesn't come up, because surgeons tend to underestimate how many patients notice anything at all, when nearly everyone does. So the surprise, not the surgery, is what unsettles people. This page and this video are the conversation a lot of people never get.
Everything you see has an ordinary explanation. Partway through, the surface of your eye gets rinsed, and for a moment the light looks watery. About a quarter of the patients in that study noticed it. It's water across the front of the eye, nothing more. Once in a while a patient describes a faint branching pattern against the light, like the veins of a leaf. That's the shadow of the blood vessels in your own retina, which a bright, even light can bring out. Rare, harmless, and a little bit wonderful.
The light gets easier within a minute, and you're in charge of it. Almost everyone finds the light very bright for the first few seconds and then settles. Two of the 102 patients found it bright the whole way through. If that's you, say so. It can be turned down. And if being awake is the part you can't get past, tell us at your pre-op visit rather than on the day. There's room to adjust how relaxed you are.
What happens during cataract surgery
Cataract surgery removes the cloudy lens inside your eye and, in nearly every case, replaces it with a clear artificial lens. It's done as an outpatient, so you go home the same day, and the operation itself takes about 10 minutes. The full walk-through, from check-in to going home, is in the cataract surgery guide.
During the operation, the cloudy lens is broken up with ultrasound and gently removed through a very small opening. The new lens is folded, placed through the same opening, and unfolds into position behind the iris. Choosing that lens is a decision of its own, and there's a guide to the lens options for it.
Before the day
Two things are worth saying out loud at your pre-op visit: whether being awake worries you, and whether you've had a bad experience with sedation before. Both change what we do on the day, and both are easy to plan for once we know.
After surgery
Right after the operation your eye may be covered with a clear shield, and you'll see light and movement through it, with vision that's still blurry. It clears over the following days and settles over the following weeks. Some itching and mild scratchiness for a day or two is normal. You'll have drops to help the eye heal, and a short list of things to avoid while it does, which is here.
A few things shouldn't wait for your follow-up visit. Sudden pain, a sudden drop in vision, or redness that keeps getting worse need a same-day call to your surgeon's office.
Common questions
Can you see what's going on during cataract surgery?
You'll see light, color, and sometimes a shadow moving across the light. You won't see the instruments or the details of the operation. For part of it your eye has no lens to focus with, and you're looking straight into the brightest light in the room, so there's nothing to build a sharp picture from.
Does cataract surgery hurt?
The sharpest thing most people feel all day is the sting of the numbing drops, and it lasts a few seconds. After that the surface of your eye can't feel touch. You'll feel cool water, some pressure, and the eyelid support, and you won't feel any cutting. If you feel more than that, say so while it's happening. More numbing and more relaxing medicine can be added at any point.
How does your eye stay still during cataract surgery?
Your eye is numbed with drops, and a small support holds your eyelids so blinking isn't your job. You look at the microscope light, which gives your eye something to hold on to. Small movements are fine and expected. If your eye needs to be steadier for a moment, your surgeon will tell you.
Why do you see colors during cataract surgery?
The best explanation we have is that the colors are your retina's response to a very bright light, not something being done to your eye. The cells in your retina that pick up different colors get overwhelmed by the microscope light and recover at different rates, so the color you see shifts and moves. It's the same reason a camera flash leaves a colored blob floating in front of you for a few seconds.
How long does cataract surgery take?
The operation itself takes about 10 minutes. Plan on a couple of hours at the surgery center for check-in, the drops, the surgery, and a short recovery before you go home.
Will I remember it?
Some people remember all of it and some remember none of it. Both are normal, and neither tells you anything about how your surgery went. The relaxing medicine affects memory more in some people than others.
The next question
Awake is the first question. The next one is usually which lens goes in, and that decision is bigger than most people expect. I made a whole video on it: 4 Cataract Lens Implant Options: Which One Should You Choose?
