Based on the experiences of 99.9% of my patients, I would reassure you by saying no. The surgical incisions involving a cataract surgery are very small. They are anything from one millimetre to less than three millimetres. The operation itself is performed under local anaesthetic or general anaesthetic and to some degree some sedation if necessary.
Cataract surgery is one of the safest operations available. However, with how commonly performed the operation is, even in experienced hands, there can be certain complications that occur. These would need to be addressed with experience of a consultant.
Cataract surgery is one of the safest operations that has probably been invented. Regarding quality of life improvement, it is probably the one that carries the highest impact on patients that is described.
The actual cataract operation time in theatre, where the surgeon is in contact with the eye and doing the technical surgery, is anything from 20 to 40 minutes. This is depending on the case complexity. On average it is about 20 to 30 minutes.
Prior to the actual day of your cataract operation, we would have met, and have had an extensive consultation. In this consultation, we will make sure there are no other problems that need to be addressed with your eyes. We would also have a discussion about the best type of lens to suit your needs.
Essentially, the most common cause of cataract is time. If you live long enough, you will develop cataracts. There is no set age at which cataracts form. I have operated a patient with the age of 35, and I think the oldest patient was around the age of 101. Commonly, it's around the age of about 50 to 70 onwards.
Essentially, the best way to think about cataracts is to look at the eye and see it as one of the world's most sophisticated cameras. It has a series of lenses at the front that captures the light and makes a clear focus picture onto the film of the eye, which is the retina.
