The landers trunkless temporary keratoprosthesis.

Abstract

OBJECTIVE:

To demonstrate the watertight seal created by the new wide-angle Landers trunkless temporary keratoprosthesis (T-TKP).

METHODS:

In 20 enucleated, porcine eyes, a 7.5-mm trephination was made, followed by capsulorrhexis and lensectomy. The T-TKP was sutured securely onto each eye. Testing the watertight seal at an intraocular pressure of 100 mm Hg was performed before and after pars plana vitrectomy.

RESULTS:

In all 20 eyes, the T-TKP maintained its watertight seal at an intraocular pressure of 100 mm Hg before and after vitrectomy.

CONCLUSION:

The Landers T-TKP is a reusable device that provides a clear view and watertight eye in the presence of corneal trephinations up to 7.5 mm in diameter. Because of its unique trunkless design, as demonstrated in the laboratory, the T-TKP should allow the surgeon greater flexibility than previous models in cases of ocular trauma.
