Abstract:AIM: To propose and evaluate a modified evisceration and implantation technique that aiming to improve the motility and simulation and long-term stabilization of the implant.
METHODS: From January 2008 to July 2011, 120 patients underwent the primary evisceration and implantation of a porous polyethylene in our hospital using the modified technique, which included secting posterior sclera flap, inserting porous polyethylene sphere into sclera cavity, the posterior sclera flap on the surface of the implant. They underwent artificial eye installation about one to two months postoperatively. Main outcome measures were mobility of the implants, mobility of the artificial eyes, conjunctiva surplus square, conjunctiva sac depth, and complications.
RESULTS: In a mean 1.5 years follow-up period(range, 1 to 3 years), mobility of the implants were excellent in 115 cases, and good in 5 cases; mobility of the artificiaI eyes were excellent in 89 cases, and good in 26 cases, and poor in 5 cases; the mean conjunctiva surplus square was 178.1±7.5mm2; the mean conjunctiva sac depth was 2.7±1.1mm; there was 2 cases of implant exposure and infection, 3 cases of subconjunctival implantation cysts, 2 cases of implant fixation sutures exposure, no case of significant enophthalmos, superior sulcus deformity, conjunctiva sac narrow, lower eyelid ectropion, or orbital cellulitis.
CONCLUSION: This technique appears to be an excellent modification for an ophthalmic socket reconstruction.
