Explain your answer aloud before opening it.
01What is retained apart?+
The eyelids, to expose the operative field.
02What is the role of the adjustment mechanism?+
It sets and maintains the opening.
03Does stronger opening always improve exposure safely?+
No. Excessive tension can damage tissue or raise pressure on the globe.
04What should identify the subtype?+
Blade design and the adjustment mechanism, not the instrument’s size alone.
