AIM:To investigate the causes and therapys of descemet membrane detachment in the patients received phacoemulsification with intraocular lens(IOL)implantation, extracapsular cataract extraction with IOL implantation and trabeculectomy respectively.

METHOD:A retrospective analysis was applied for 1 356 eyes which had received one of above-mentioned surgeries from January 2012 to March 2015. Total 29 eyes with descemet membrane detachment were noted.

RESULTS:After the appropriate treatment, no corneal endothelial decompensation happened in the 29 eyes, and the visual acuity recovered to 4.1-4.8.

CONCLUSION:The main reasons for descemet membrane detachment are the anatomical features of descemet membrane, the incision adopted in the intraocular surgeries, the injuries caused by the surgical instruments and the potential pathological changes in the patients' cornea.Timely detection of descemet membrane detachment during and post-operation and adoption of proper treatment is important for the restoring of the visual acuity.
