Hi! Sparkly.
Early days yet for the swelling to settle which may be the problem and is no big deal.
However when you had your cataracts done, didnyou have an intraocular lens inserted?
Also were you examined by medic after you had fallen?
I would be interested to get the comments from your Optician.
The cataracts were very painless, I think they just scrape away the debris and put a bit of plastic in. The amazing thing was that a grey sky turned blue and what I thought was yellow paint turned brilliant white. Both eyes still see brightness, but the left eye focus is not very good.
Ah! Then you did have an intra occular lens inserted and the fall may have dislodged it a fraction. Still no big deal but your Optician will coment further.
