A study of the classification of Descemet membrane detachment after phacoemulsification and lens implantation by AS-OCT

Objective AS-OCT was used to classify posterior corneal elastic detachment after surgery of phacoemulsification and lens implantation for guiding clinical diagnosis and treatment. Methods We retrospectively analyzed the results of AS-OCT in 26 patients (26 eyes) with after Phacoemulsification and lens implantation of cataract.The clinical classification was made and the percentage of each type was analyzed according to the location and extent of the detachment of the posterior corneal elastic layer, and the cause and clinical treatment were analyzed after that. Results According to the results of AS-OCT examination, 26 cases (26 eyes) were found to have different degrees of corneal detachment associated with surgical incision. It can be divided into three types according to the location and extent of posterior elastic detachment. The first type was simple posterior elastic layer detachment, which was only confined to the surgical incision (out of the range <1/4 corneal area) , accounting for 69.20% (18/26) of the total number of cases, The localized posterior elastic layer dislocation accounted for 42.30% (11/26) , and the posterior lip layer was 26.90% (7/26) .The second type is symmetrical posterior elastic detachment, which refers to the dislocation of incision and symmetry of it in the limbus area (1/4 corneal area
