Abstract Details


The aim of this study is to compare the postoperative corneal endothelial cell loss, after standardized phacoemulsification using Infiniti (Alcon, USA) and Signature (Abbott, USA) machines.


This study was conducted at the ophthalmology department, Cairo University, Egypt, in a six months period.


This study was a prospective cohort study. It comprised 30 eyes of 30 patients assigned for cataract surgery, with different grades of senile cataract. Patients were divided into 2 groups: Group A was operated by the Infiniti machine, and group B was operated by the Signature machine. Endothelial cell count was measured preoperatively and 1 month postoperatively using the Specular Microscope. At the end of surgery, we recorded the Effective Phacotime (EPT) and the Cumulative Dissipated Energy (CDE).


Percentage of mean cell loss ± SD in the Infiniti group was 9.80±3.29 %, compared to 13.83±5.61 % in the Signature group (p = 0.032). The mean EPT in the Infiniti group was 12.04 ±6.36, Vs 14.5 ±10.5 in the Signature group (p = 0.44). The mean CDE in the Infiniti group was 16.37±10.5, Vs 20.3±16.9 in the Signature group (p = 0.449).


Postoperative endothelial cell loss following phacoemulsification by the Signature machine was significantly higher than that following phacoemulsification using the Infiniti machine.
