Do pupils dilate and constrict after cataract surgery?

Most large post op pupils will return to normal after surgery. However, in a small number of cases, the pupil may remain slightly dilated permanently.

What is sluggish pupil constriction?

When the light is withdrawn from one eye, the opposite pupil should dilate simultaneously. This response is called the consensual light reflex. A sluggish pupil may be difficult to distinguish from a fixed pupil and may be an early focal sign of an expanding intracranial lesion and increased intracranial pressure.

Does ptosis go away after cataract surgery?

Duration and treatment

Is ptosis a complication of cataract surgery?

An often over-looked complication of routine cataract surgery is post-operative ptosis. This form of ptosis is often transient, although persistent ptosis may require surgical intervention. The causes include eyelid edema and hematoma, anesthesia myotoxicity, and use of a lid speculum or bridle suture.
