Hrithik underwent the surgery after he was diagnosed with chronic Subdural Hematoma, a serious condition caused as a result of head injury. The actor sustained an injury during the shoot of an action sequence in his upcoming film "Bang Bang" which also stars Katrina Kaif.

Following the surgery, several popular Bollywood celebrities including Shah Rukh Khan, Karan Johar, Uday Chopra and Sanjay Kapoor visited the actor at the hospital.

Hrithik, who will be discharged in a couple of days, is expected to resume the shooting of "Bang Bang" in four-weeks time. The actor will also be seen promoting his upcoming superhero venture "Krrish 3" which is set to hit screens on 4 November.
