Simplified technique for suturing a temporary keratoprosthesis for pars plana vitrectomy

Area of Science:

• Ophthalmology
• Surgical Techniques
• Corneal Surgery

Background:

• Opaque corneas present challenges for intraocular surgery.
• Temporary keratoprostheses offer a solution for visualization.
• Efficient suturing methods are crucial for patient outcomes.

Purpose of the Study:

• To present an efficient suturing technique for the Landers wide-field temporary keratoprosthesis.
• To address the need for secure temporary keratoprosthesis placement in eyes with corneal opacity.

Main Methods:

• Preplaced two-suture technique described.
• Sutures placed in partial-thickness corneal stroma, parallel to the limbus.
• Suture ends passed through keratoprosthesis holes and secured.

Main Results:

• The temporary keratoprosthesis was firmly secured with two sutures.
• Clear visualization was achieved for extensive intraocular procedures.
• The technique proved effective for managing corneal opacity.

Conclusions:

• The described two-suture technique offers an efficient method for temporary keratoprosthesis fixation.
• This technique reduces the duration of globe opening during surgery.
• It facilitates complex intraocular procedures in eyes with opaque corneas.
