A modified evisceration technique with scleral quadrisection resulted in successful implantation of porous polyethylene implants without complications such as implant extrusion or exposure.
The technique was examined in an interventional prospective study of 154 patients who underwent implantation of a porous polyethylene implant with a 18 mm or larger sphere. Complications were the main outcome measures studied and included implant extrusion and exposure, cosmetic results, significant enophthalmos, conjunctival dehiscence, superior sulcus deformity or orbital cellulitis.
Clinicians found no major complications.
"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," they said. "The cosmetic appearance and implant mobility were satisfactory."
The modified evisceration technique involves quadrisecting the sclera, then "suturing the implant with each rectus muscle through the scleral petal," researchers said. It is finished by using two layers of the sclera to cover the implant.
