Even though you won’t feel pain, you may be curious or concerned about the sensations during cataract surgery. Here’s the typical experience:
Sight: You won’t see the surgery instruments in detail. With a numbed, dilated eye and bright microscope light, most patients report seeing a kaleidoscope of colors or a bright light, maybe moving shapes or a vague awareness of something happening, but nothing clear or scary. Some see swirling light patterns, or a foggy “watercolor” effect of lights. It’s often described as looking through a frosted glass at a light show. You definitely won’t see any incisions or needles coming at your eye – the operative field is just a bright blur.
Sound: You will hear the surgeon and nurses talking (they might be giving gentle instructions like “look at the light” or discussing among themselves). You’ll also likely hear a soft buzzing or humming sound – that’s the phacoemulsification ultrasound machine breaking up the cataract. It’s not loud, but audible. If a femtosecond laser is used for part of it, you might hear a clicking during the laser portion in a separate room. Also, some ORs play music softly in the background to keep atmosphere relaxed – you might catch that.
Feel: Thanks to anesthesia, you shouldn’t feel pain. You might sense gentle pressure or movement at times. For instance, when the surgeon irrigates fluid inside the eye, you could feel a cool wash sensation. When inserting the new lens, maybe a slight pressure but no sharpness. If they do a speculum to hold your lids, you might feel that at the very start as a slight tension on the lids, but after that, the numbing eliminates discomfort. Some patients report feeling nothing at all but the time passing; others say they felt a tiny pressure here or there that was not bothersome. You might feel your head being touched or steadied. If you have any sensation, you can speak up – often additional numbing can be given right away. (Just be careful not to move too much when talking because that can cause issues.) Because of sedation, many people are so relaxed they don’t remember much.
Overall, the experience is strange but not unpleasant – sort of like a short light show with a background hum. (In fact, many patients describe the experience as cool, interesting, psychedelic/trippy, beautiful… Artists in particular often really enjoy all the colors). And it’s over before you know it; a lot of people say “I can’t believe we’re done already” because it felt like just a few moments.
