Fisher hurt his left eye while on Green Bay's kickoff return coverage unit late in the Vikings game. Fisher sat out a few plays but returned for the rest of the contest.
"I just fell to the ground," Fisher said. "For a second everything was a little blurry."
The laser surgery repaired small holes in Fisher's retina. Fisher deemed the surgery precautionary.
"The only reason I had to do the surgery is because they said there's always a possibility of taking a hit and having a detached retina," he said.
Fisher said he felt he could have practiced on Wednesday. As a preventive measure, Fisher, listed as probable on the injury report, will wear a clear visor on his facemask against Cincinnati.
"I've just got to be able to go out there and take care of my business," Fisher said, "whether it's handling running responsibilities, or pass responsibilities. I have to stay focused and stay in a good position to help this team win."
Fisher is starting in place of Ahman Green, who was placed on injured reserve this week with a ruptured quadriceps tendon. Green's backup Najeh Davenport was lost for the season when he sustained a broken right ankle on Oct. 9 against New Orleans.
