A new temporary keratoprosthesis for pars plana vitrectomy.

Area of Science:

• Ophthalmology
• Surgical Innovation
• Corneal Surgery

Background:

• Opaque corneas and proliferative vitreoretinopathy present significant challenges for vitreoretinal surgery.
• Accessing intraocular structures for procedures like pars plana vitrectomy can be severely limited.
• Existing methods may not adequately address the dual need for corneal clarity and surgical access.

Observation:

• A new temporary keratoprosthesis, constructed from silicone rubber, was utilized.
• This device was secured to the trephined corneal bed using four 10-0 nylon sutures.
• The keratoprosthesis allowed for a clear view of intraocular structures.

Findings:

• Successful pars plana vitrectomy combined with silicone oil injection was performed using the temporary keratoprosthesis.
• The device facilitated vitreoretinal surgery, including in the challenging pars plana and vitreous base regions.
• The keratoprosthesis was subsequently replaced with a corneal graft post-vitrectomy.

Implications:

• This temporary keratoprosthesis offers a viable solution for performing essential vitreoretinal surgery in eyes with corneal opacity.
• It enhances surgical visualization and access, potentially improving outcomes for complex retinal conditions.
• The technique highlights the potential of temporary prosthetic devices in managing challenging ophthalmic cases.
