Temporary graft for closed-system cataract surgery during corneal triple procedures

Abstract

Performing phacoemulsification during a triple corneal procedure has many advantages. Operating in a closed chamber makes surgery easier and safer. In some cases, however, a dense corneal opacity may prevent closed-chamber surgery, necessitating the use of an open-sky technique. In these cases, a temporary corneal graft using a corneal button not suitable for penetrating keratoplasty is proposed to allow phacoemulsification and foldable intraocular lens implantation through a corneal tunnel. The temporary corneal graft is replaced with a permanent graft after these steps are completed. This technique was effective in 3 patients with cataract and dense corneal opacity.

Evaluation of stability and biocompatibility of PHEMA-PMMA keratoprosthesis by penetrating keratoplasty in rabbits

“…The single interrupted suture and double-layer continuous suture methods are commonly used in artificial cornea transplant or keratoplasty [121620]. Extrusion of the device was observed frequently in the single interrupted suture method than in the double-layer continuous suture in our pre-experimental study (data not shown).…”

Efficacy of Chandelier Illumination for Combined Cataract Operation and Penetrating Keratoplasty

“…However, corneal opacities were still present after this procedure, visual acuity was less than after a PKP triple procedure, and cosmetic rehabilitation was difficult because of the dislocated pupil and remaining corneal opacity. Nardi et al12 showed that temporary corneal grafting using corneas that were unsuitable for PKP enabled CCC, PEA, and IOL implantation in a closed state, but this technique would be prohibitively expensive in most countries due to the need for an additional corneal button.…”
