India’s hockey goalkeeper Baljit Singh, who is undergoing treatment in the United States for his injured eye, will go under the knife for the fourth time in Alabama on Monday.

The doctors, treating the 28-year-old custodian, have decided to carry out another operation in order to regulate pressure on his right eye, which sustained a global rupture when he was struck by a golf ball during a training session at Pune in June this year.

“I had two surgeries done on my right eye. After about two weeks post operation, I was seeing shadows and within a week I was able to see images and colours. There has been improvement in my vision day by day and I am getting better,” Baljit said from Alabama.

“But pressure in the right eye is low compared to the left, so doctors at the hospital have advised another operation to increase the pressure on the right eye. Silicon oil will be injected into my retina to increase the pressure,” he added.

The operation is scheduled at 0030 IST. Baljit, who is being treated by renowned ophthalmologist Robert Morris in Alabama, has regained partial vision as his injured eye has been operated upon thrice, with the last being on September 8.

“The doctors have assured me that after this operation, pressure on the right eye will gradually increase. After two weeks (following the operation), I will have marginally better vision,” Baljit said.
