Purpose:
To propose and evaluate a modified evisceration technique that aiming to minimize the extrusion or exposure and improve motility of the implant.
Design:
Interventional prospective study.
Methods:
There were 154 patients referred to our clinic from March 1, 2003 to March 1, 2007. All the patients underwent the primary evisceration and implantation of a porous polyethylene implant using the modified technique, which included quadrisecting the sclera, suturing the implant with each rectus muscle through the scleral petal, and then covering the implant with 2 layers of the sclera. Main outcome measures were complications such as conjunctival dehiscence, implant extrusion, implant exposure, significant enophthalmos, superior sulcus deformity or orbital cellulitis, and cosmetic outcome.
Results:
All patients received porous polyethylene implants with 18 mm or larger sphere. In a mean 3.5 years follow-up period (range, 1 to 5 years), there was no case of conjunctival dehiscence, implant extrusion, implant exposure, significant enophthalmos, superior sulcus deformity, or orbital cellulitis. The cosmetic appearance and implant mobility were satisfactory.
Conclusions:
This technique appears to be an excellent modification for anophthalmic socket reconstruction.
