Hi there,
I am sorry to hear you have been in pain which has also affected your academic performance.
It's great that you took the necessary steps and contacted professionals who can help you with your eye pain. Additionally, universities typically consider medical reasons as valid grounds for coursework extension as long as you provide required decumentation, which you have.
However, each university has its own policies and regulations regarding extensions, so even if you share proof of your hospital appointments and medical condition, the final decision rests with the university as they will assess your application.
It would be best if you reach out as soon as possible to communicate openly about your situation with your mentors or academic support groups. If you encounted any difficulties, make sure to contact your university's student support services for further advice.
I hope I managed to help!
Best of luck,
Melanie
