What is the primary purpose of an eyelid speculum during surgery?

The primary purpose of an eyelid speculum during surgery is to hold the eyelids open. This instrument is essential for providing the surgeon with an unobstructed view of the eye and surrounding structures, which is crucial for performing delicate procedures. By securely holding the eyelids apart, the speculum prevents involuntary blinking and minimizes the risk of damage to the eye during the surgery. This visibility is especially important in ophthalmic surgeries where precision is key.

The other options represent functions that are not served by an eyelid speculum. For instance, cutting tissue is typically performed with specialized surgical instruments like scissors or knives. Grasping sutures is the role of forceps, which are designed for holding and manipulating sutures during procedures. Providing suction is managed by suction devices that remove blood or other fluids from the surgical site, ensuring a clear operative field.
