3rd nerve palsy. 75. please suggest me.

My father suffered 3rd nerve palsy in 2008 and recurrent partial 3rd nerve palsy as mentioned by neurologist in 2015 also and started clopitab lipirose and cilaheart. Then Angiogram done on 11/06/2016 it indicated CAD mild disease.l He had some speach disturbed and mouth deviation in 12 October 21 then consulted neurosurgeon he prescribed clopitab cv gold for one month and there on continued same prescribed above. Now he had right eye minimised and vision distrubance. I think that this happened due to heavy consumption of ghee. In October 2021, he consumed lot of ghee in the form sunnundalu, i thought that caused mild stroke like symptoms, he recovered completely within two months that time. Now he was on clopitab 75, lipirose 10, cilaheart 10 and ecosprin 75. Please suggest me. Thank you
