Temporary keratoprosthesis used in the joint surgeries of anterior and posterior ocular segments;

Objective:To evaluate the efficacy and safety of penetrating keratoplasty and posterior segments with temporary keratoprosthesis and infant donor cornea used in combined operations.

Methods Six patients with bullous keratopathy and retinal detachment after intraocular lens implantation experienced the combined surgery including pars plana vitrectomy and penetrating keratoplasty,and during the combined surgery,we used temporary keratoprosthesis.

· AIM: to assess the effectiveness of a combined procedure ( pars plana vitrectomy with temporary keratoprosthesis, vitreoretinal surgery, and penetrating keratoplasty) .

Keratoprosthesis design and biological response to a synthetic cornea;

Biocompatible study of hydroxyapatite modified titanium skirt for keratoprosthesis in vivo;

This paper probes into the principles that should be followed in practicing the job training for library s temporary workers, and introduces emphatically several more proper training methods for library s temporary workers in the current period.
