LAS VEGAS — Light intensity was significantly decreased for patients undergoing cataract surgery with a 3D visualization platform compared with a standard operating microscope, according to a study presented here.
In his presentation at the American Society of Cataract and Refractive Surgery meeting, Eric D. Rosenberg, DO, MSE, compared the coaxial light intensity needed for cataract surgery and the rate of postoperative visual recovery in 51 eyes using either the 3D system or a standard microscope. Twenty-seven eyes underwent surgery using the 3D visualization system affixed to the operating microscope during the procedure.
The average light intensity used in the group with the 3D visualization system was 18.5%, which was significantly less than the 43.3% used in the standard group (P < .001). The eyes that were operated on with the 3D visualization system had a postoperative day 1 visual acuity within two lines of the postoperative month 1 visual acuity 81.5% of the time compared with 54.2% of the time in the standard group (P = .04).
No intraoperative or postoperative complications were found in either group.
Rosenberg said that every piece of equipment in the operating room has a dosing recommendation for lighting, which is important to review before performing procedures.
“I think that everybody should pick up their operating microscope user manual and read it,” he said. “That’s what I tell all my residents and fellows.”
