Hello and welcome to the forum. I'm so sorry to hear about your father. How is he doing this week? You are hopefully working with his doctor and also doing some rehabilitation specifically to help with the residual effect of the stroke. From my understanding, droopy eye lids post stroke can improve. This actually has a name, ptosis. And a patient would be encouraged, normally, to force the use of the affected eye for a few minutes each hour to gradually build up muscle tolerance. If that is not successful, surgery is sometimes an option. Here's an article https://eyewiki.aao.org/Ophthalmologic_manifestations_of_brainstem_stroke_syndromes I would most certainly have him doing rehab as soon as possible as most improvement comes within the first 3 to 6 months post stroke. As to long term residual issues, that's a possibility with a brain stroke So difficult and counseling can be beneficial when that is the case to deal with the emotional stress of these changes. Let us know how your dad is doing.
