Four-petal evisceration: a new technique.

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Ocular evisceration is a surgical procedure to remove the eye's contents while preserving the sclera.
• The use of large orbital implants can be limited by the available scleral tissue and wound closure tension.

Purpose of the Study:

• To present a new 4-petal evisceration technique.
• To enable the use of large orbital implants.
• To achieve tension-free wound closure after evisceration.

Main Methods:

• An interventional prospective study was conducted.
• The technique involves quadrisectioning the sclera.
• A large orbital implant is placed and the sclera is sutured in two layers over the implant.

Main Results:

• 73 eyes underwent the procedure.
• Orbital implants of 18-22 mm were used in all cases.
• One case of mild superior sulcus deficiency occurred; no implant extrusions were reported.

Conclusions:

• The 4-petal evisceration technique is technically straightforward.
• The technique offers excellent results with a low complication rate.
• It allows for the successful implantation of any size orbital implant.
