What ophthalmic instrument is used to grasp the eyelid for the purpose of exposing a chalazion?

The DesMarres eyelid retractor is specifically designed to grasp the eyelid, allowing for better exposure of the area where a chalazion is present. This instrument is particularly useful in ocular procedures because it gently holds the eyelid open without causing damage to the surrounding tissue. The retractor provides a clear view of the chalazion, facilitating a more precise and effective surgical intervention.

In contrast, while forceps may be used in various surgical scenarios, they do not provide the same level of exposure to the eyelid as a DesMarres retractor. Scissors are used for cutting rather than grasping or holding the eyelid open, and a speculum, while used in some other surgical contexts to hold open cavities or orifices, is not tailored for the delicate nature and specific application within the field of ophthalmology that involves eyelid management.
