As your doctor has informed his vein has dried it could be vascular occlusion.
Was his vision better before cataract surgery.
If he had a very poor vision prior to cataract surgery then it could have been preexisting.
Please check with your doctors prescription about the status of pupillary reflex, grade of cataract and fundus findings before the surgery to get a more clear idea of preexisting or otherwise situation.
