TL; DR; Its highly unlikely Murli donated his eyes.
Akash got his cornea probably from
1. Simi
2. Someone else, not Murli.
Remember the way we were shown the movie ending. Akash & Doctor were going by the car toward private jet. And the scene is over and we see Akash in London. What happened after they were driving is just a story Akash told to Sophie (Radhika Apte). Remember at last, Sophie tells Akash that he should have agreed to Doctor and should have transplanted Simi's cornea.
Pay full attention to what Akash said on this: nothing. He just turned away from her as if he were hiding something (may be story of that rabbit (actually MacGuffin) that resides on his stick!)
.
After that scene, the significant scene turns out that Akash knocks a can out of his path. This clearly implies that he did agree to what the Doctor had to say about donating Simi's organs and get a share of money &
- Probably his cornea matched with Simi's and they transplanted to Akash's eyes, or
- He got enough money to get someone else's cornea, but not Murli's, for cornea transplant has to be done within 1-2 hours after death, so its unlikely that they got to same hospital where Murli was dead and get there that fast. They didn't even know where were Murli and Sakhu were.
