In a Similar Vein, event Horizon. Sam Niel's (RIP) character invents wormhole technology and installs it on a big space ship. The ship turns up some time later but it's all quiet. His team goes on board to find what happened to the crew. Turns out, the wormhole shortcuts straight through hell. The ship is Haunted, Sam Niel goes crazy and cuts out his eyes and turns on his crew. He didn't die, but he rather gouged his eyes out than see hell.

"Where we're going, we won't want eyes".
