The Pentacam is a sophisticated multiple purpose device for evaluating all aspects of the cornea. This instrument takes careful 3D images of the front of your eye using a special rotating camera. It captures information on 25,000 separate points in the eye in about one second. Crown Laser Center was one of the first practices in St. Louis to offer this state of the art technology. The information it gathers allows us to ensure that your eye is healthy and ready for an excellent surgical result.
