Do I need cataract surgery in both eyes?
Often both eyes eventually need it, but not usually on the same day. Most surgeons operate on one eye at a time, with the second eye treated once the first has settled, so that the eye that is healing is not the only eye you have to see with.

In more detail
The interval between the two operations is a clinical decision and varies. What is worth planning for is that the second eye will need its own assessment and its own measurements, because the two eyes are rarely identical.
What this answer depends on
- How much each eye is affected
- Whether you could manage if one eye were temporarily blurry
- The surgeon’s usual interval between eyes
