Retroscleral Implantation Technique for Porous Polyethylene Orbital Implant After Evisceration

Abstract

Abstract. The authors developed a technique for the retroscleral implantation of a porous polyethylene orbital implant after evisceration for the placement of an adequately large orbital implant without wound tension. The surgical results of the technique in 27 patients are reported. The technique involves the severance of the optic nerve after standard evisceration and the insertion of the orbital implant into the retroscleral and intraconal space through the side of the scleral shell. All patients received a 20-mm orbital implant. No complications such as infection, implant exposure, or worsened implant motility were observed during the average follow-up period of 22.4 months. Retroscleral implantation of the orbital implant after evisceration may be an appropriate procedure that allows placement of a large orbital implant without exposure or decreased implant motility.

Scleral Shield: Primary Results of a New Surgical Technique in Augmenting Porous Orbital Implant Protection

“…With this technique, double-breasting the scleral cover is possible and enhances implant protection (14). In 2005, Choung et al (16) described retroscleral implantation of a porous polyethylene orbital implant after evisceration for the placement of an adequately large orbital implant without wound tension. The technique involves severance of the optic nerve after standard evisceration and insertion of the orbital implant into the retroscleral and intraconal space through the side of the scleral shell with good postoperative motility and no reported complications.…”

Evisceration with four anterior relaxing incisions and circumferential posterior sclerotomies with porous polyethylene orbital implants: an 8-year study

“…In this surgery, it is important to reduce volume loss and, at the same time, decrease tension on the surgical wound. Many techniques have been recommended to achieve these goals: relaxing scleral incisions, posterior sclerotomies, scleral flaps, implant coverage by multiple scleral layers and others (Stephenson 1987;Kostick & Linberg 1995;Lee et al 1995;Yang et al 1997;Long et al 2000;Massry & Holds 2001;Choung et al 2005;Madill & Maclean 2005;Sales-Sanz & Sanz-Lopez 2007). Fibrovascular ingrowth in the implant begins at the sclerotomy sites (Shields et al 1991;Sarvananthan et al 1999).…”

Evisceration with Four Elongated Anterior Scleral Incisions and Circumferential Cogwheel-like Posterior Sclerotomies for Moderate to Severe Phthisis Bulbi

“…Alternatively, a complete sclerotomy may be needed, whereby the scleral shell is bisected into two complete halves from the superotemporal quadrant to the inferonasal quadrant. [5] Posterior sclerotomy only might not be adequate in cases of severe phthisis and globe contraction. Therefore, several modi cations of the traditional evisceration technique combining various types of sclerotomies can be implemented to increase the scleral volume in normal-sized eyes as well as in severely phthisical eyes.…”
