About your cataract surgery

  • Having cataract surgery – video transcript

    Patient: Before the operation, I noticed that things were getting dimmer, blurred and yellowish. When the word 'cataract' was mentioned I thought they can correct that, I'm sure they can correct that. So I was a little bit relieved at the time. The three months before my operation, it started to progress really fast and it got really scary, I just then thought, get me sorted. On the day of the surgery, I took my tablets as normal and I came to the eye department at St Thomas'. 

    Nurse: Hello, is this Mrs Bagnall? Good afternoon. 

    Patient: A nurse did some checks to make sure it could all go ahead. I met the surgeon. 

    Surgeon: Are you happy with that? 

    Patient: I am.

    Surgeon: Lovely, OK. Thank you, lovely. And then just keep looking straight ahead. 

    Patient: The nurse brought me into the operating theatre. They used lots of drops to numb my eye, it stung a bit but it wasn't too bad. They told me if I wanted to move or cough, I had to warn the surgeon. They put a drape over my face and then a clip to stop me blinking. It was a bit uncomfortable but it didn't hurt. 

    Surgeon: Keep your head really still for me.  

    Patient: They streamed water over my eye, they told me to look into the light for the whole operation. 

    Surgeon: You're staying really still for me, that's great. 

    Patient: All I could see was lights and shadows.

    Surgeon: OK, lovely, so the cataract's out now, I'm just going to get it ready for the new lens.  

    Patient: When I was in theatre, I felt the pressure but I didn't feel any pain. I was quite surprised and then everything stopped and it's like, is that it? After the operation they put a shield over my eye. I had a rest, then they showed me how to care for my eye and we booked in my next appointment.

    I expected to have some pain but everything was normal and I still can't believe how quick and how good it is. Today my eyesight is worse close up but as long as I wear reading glasses I'm fine. Other than that, my vision is great. So very, very happy, I'm very happy I did this.
