Temporary keratoprosthesis for transscleral fixation of posterior chamber intraocular lenses with penetrating keratoplasty

Temporary keratoprostheses in anterior and posterior segment surgery: A narrative review of their history and development

Visualizing the posterior segment during vitreoretinal surgery can be difficult in eyes with concurrent corneal opacity. Temporary keratoprostheses have emerged as devices that ensure visibility of the posterior vitreous cavity while simultaneously preserving the donor corneal graft. Several models of these devices are described in the current literature, and new design models and surgical techniques surrounding their use continue to be developed. We summarize the different temporary keratoprosthesis models with their associated surgical techniques, advantages, and shortcomings; discuss the clinical results of studies utilizing these devices; and examine alternative tools and techniques for approaching combined anterior and posterior segment operations.

A review of suturing techniques for posterior chamber lenses

PURPOSE OF REVIEW

To evaluate the outcome of last the 15 years' experience with the transscleral suture fixation technique of posterior chamber intraocular lens (PC IOL).

RECENT FINDINGS

The implant of an anterior chamber IOL, especially the iris-claw lens, is safer and a better option than the transsclerally fixed IOL.

SUMMARY

After bibliographic review of anterior chamber lenses implant results with transscleral fixation, we conclude that the number of complications is less in the iris fixation lens.

Simplified technique for suturing a temporary keratoprosthesis for pars plana vitrectomy

PURPOSE

To describe an efficient technique for suturing a Landers wide-field temporary keratoprosthesis for intraocular surgery in an eye with an opaque cornea.

METHODS

Two sutures were preplaced at partial thickness into corneal stroma parallel to the corneoscleral limbus. Suture ends were placed through corresponding holes in the keratoprosthesis and tied.

RESULTS

The temporary keratoprosthesis was held firmly in place with two sutures and provided clear visualization for extensive intraocular surgery.

CONCLUSION

The preplaced two-suture technique for securing a temporary keratoprosthesis to the globe decreased the time that the globe was open.
