Simplified no pressure eyelid retractor for cataract surgery

Area of Science:

• Ophthalmic surgical instrumentation
• Medical device design

Background:

• Traditional eyelid retractors can cause globe pressure and obstruct the surgical field with eyelashes.
• A need exists for simple, inexpensive, and effective eyelid retraction solutions in ophthalmic procedures.

Purpose of the Study:

• To develop and describe a novel, single-use, solid blade eyelid retractor.
• To evaluate the retractor's efficacy in maintaining a clear surgical field without ocular contact.

Main Methods:

• A simple, inexpensive, solid blade eyelid retractor was designed.
• The retractor was assessed for its ability to retract eyelids without touching the globe.
• Its capacity to clear eyelashes from the operative field was evaluated.

Main Results:

• The designed eyelid retractor makes no contact with the ocular globe.
• The device exerts no pressure on the globe during use.
• Eyelashes are effectively cleared from the surgical operating field.

Conclusions:

• This novel eyelid retractor offers a safe, effective, and economical solution for ophthalmic surgery.
• The design facilitates improved visualization by eliminating globe pressure and eyelash interference.
