Corneal protection during general anesthesia for nonocular surgery

Area of Science:

• Ophthalmology
• Anesthesiology
• Surgical Complications

Background:

• Corneal abrasion is a frequent complication during general anesthesia for nonocular procedures.
• It can lead to severe outcomes like microbial keratitis and scarring.
• Current eye protection methods lack standardization and effectiveness.

Purpose of the Study:

• To review the causes of perioperative corneal abrasions.
• To compare different eye protection strategies during general anesthesia.
• To identify optimal methods for preventing corneal abrasions.

Main Methods:

• Literature review on corneal abrasion etiology.
• Comparative analysis of various eye protection techniques.
• Evaluation of effectiveness and side effects of interventions.

Main Results:

• Taping the eye provides protection equivalent or superior to other methods.
• Taping is associated with fewer side effects compared to alternatives.
• Petroleum gel should be avoided with electrocautery/oxygen; preservative-free ointments are preferred.

Conclusions:

• Taping is a highly effective and safe method for corneal protection during general anesthesia.
• Preservative-free eye ointments are recommended over those with preservatives.
• Emerging methods like Geliperm may offer benefits in specific surgical contexts.
