[Implantation of porous polytetrafluoroethylene orbital inserts: complications. Communication 2]
Abstract:
The purpose of the study was to analyze the pattern and frequency of complications following 230 implants of porous polytetrafluoroethylene (PTFE) orbital inserts. The total frequency of the complications to be treated was 7.4%. Among them there were pointed conjunctival perforations during enucleation (1.3%); early exposures of orbital inserts due to surgical defects (2%); late exposures caused by the planned replacement of an old prosthesis by a new one that had proved to be poorly adjusted (1.4%); significant bleapharoptosis (2%); lower eyelid atony (0.7%). Noteworthy is the fact that there were no infectious complications. Thus, implantation of PTFE orbital inserts is attended by a very narrow range of the complications, which are typical of this branch of ophthalmosurgery, whose frequency is not greater than the use of implants made from other porous materials.
