Purpose
To compare perioperative parameters of dual linear foot pedal control with conventional linear control during standard cataract surgery.
Setting
-
Methods
Prospective comparative case series of cataract surgeries performed using dual linear foot pedal control (group 1, n=25) or co-linear control (group 2, n=21). Eyes were divided in two groups based on the foot pedal mode used during the surgery. Baseline characteristics were overlapping. Differences in endothelial cell density (ECD), vacuum, phaco power (US MED), surgical time and balanced salt solution (BSS®) used were evaluated. Outcomes were recorded at follow-up visit one month after the surgery.
Results
Mean ECD dropped in both groups at 1 month of follow‐up (group A: preop. mean ECD 2361±306
– postop. mean ECD 2253±421 / group B preop. mean ECD 2481±211 – postop. mean ECD 2266±346) . Mean surgical time was 9.2±0.2 min in group 1 and 13.3±1.0 min in group 2. Mean vacuum used was 323±30 in group 1 and 280±43 in group 2. US MED was 11.8±3.4% in group 1 and 9.1±2.8% in group 2.
BSS® used was 62±18 ml in Group 1 and 69±17 ml in Group 2.
Conclusions
Corneal endothelial cell loss was not significantly higher in group 2. Intraoperative results indicate that in group 1 more vacuum and phaco power were used. Surgical time was higher in group 2 than in group 1. Therefore dual linear control mode results in a reduction of surgical time allowing an higher use of vacuum.
