title: The use and preliminary results of the Troutman surgical keratometer in cataract and corneal surgery.
abstract: The Troutman microsurgical keratometer has been shown to be useful in monitoring intraoperative procedures, and it has been demonstrated in the case of cataract and keratoplasty to have a significant influence on the control of operatively induced astigmatism. It is applicable to any surgical procedure which has the potential of altering permanently and unpredictably the corneal curvatures. Intraoperative keratometry has clearly demonstrated some inadequacies of our current cataract and keratoplasty techniques. It is now being used to guide our efforts toward a more rational control of the vexing problem of astigmatism.
