Our Long Island facility boasts five High Definition Laparoscopic Operating Room Suites with the latest technologically advanced systems. We use High-Definition surgical cameras, scopes, monitors, and digitally advanced computers to capture the best picture available. Our equipment is connected to an intricate voice activation system, allowing Dr. Geiss and Dr. Powers control over each system. In addition, our voice activated robotic arm can be used during any laparoscopic procedure to precisely position the laparoscope for the surgeons. These advanced technology systems act in concert to provide control and precision to the surgeons and enhance the efficiency of the surgical staff. This optimal surgical environment, combined with the skill of the surgical staff and preparedness of the patient, contribute to superior patient outcomes and an exceptional patient experience.
