Certified Instrument Specialist (CIS) 2025 Practice Exam – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What is the function of the Lieberman Eye Speculum in surgical procedures?

To grasp tissues

To retract eyelids

The Lieberman Eye Speculum is specifically designed to retract the eyelids during surgical procedures. This instrument allows healthcare professionals to keep the eyelids open and out of the way, providing a clear view of the eye for examination or surgical intervention. The design of the eye speculum facilitates access to the eyelid margins and the ocular surface while making the patient more comfortable by reducing the need for constant manual retraction of the eyelids.

In contrast, instruments that grasp tissues or stabilize fractures serve different functions related to tissue manipulation or orthopedic interventions, and guiding drill bits pertains to precision in drilling tasks, neither of which are relevant to the role of the Lieberman Eye Speculum. Understanding the specific application of each surgical instrument is crucial for effective practice in a clinical setting.
