A simple method of conjunctival dissection for Gunderson flaps.

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Conjunctival dissection during Gunderson flap procedures can be challenging and time-consuming.
• Inadvertent buttonholing and excessive conjunctival retraction are common complications.

Purpose of the Study:

• To present a simplified and precise method for dissecting conjunctiva from Tenon's capsule.
• To improve surgical efficiency and reduce complications in Gunderson flap procedures.

Main Methods:

• Utilizing gentian violet marks as visual guides.
• Employing a needle and two pairs of scissors in series for dissection.
• Separating superior bulbar conjunctiva from superficial Tenon's capsule along semimeridians.

Main Results:

• The technique provides clear surgical landmarks.
• Reduced risk of inadvertent buttonholing of the conjunctiva.
• Minimized conjunctival retraction due to uneven dissection.

Conclusions:

• This gentian violet-guided method simplifies conjunctival dissection.
• The technique enhances surgical precision and tissue management.
• It offers a valuable improvement for Gunderson flap procedures.
