Abstract Details

Purpose:

To evaluate the wound integrity and leakage with a dynamic approach during cataract surgery.

Setting:

Ophthalmology Department, Muğla Sıtkı Koçman University, Faculty of Medicine, Muğla, Turkey

Methods:

During the surgery, after removal of viscoelastics, aspiration probe was removed. Continuous leakage from incision was appeared by the continuous irrigation mode, and then stromal hydration was performed at the site of leakage until the leakage was stopped. While the continuous mode was on, absence of leakage was accepted as an enough criteria for ending the stromal hydration. The main outcome measure was the presence or absence of directly observed wound leak after stromal hydration. Trypan blue 0.0125% was applied over the wound locations to detect the wound integrity and leakage.

Results:

106 consecutive eyes of 96 patients (all 318 wounds; 106 irrigation port-left; 106 aspiration port-right; 106 main incisions) were observed. The dye test revealed leakage of aqueous from 26 wound locations of 24 eyes ( 8.2% of 318 wounds): irrigation port in 13 eyes, aspiration port in 4 eyes, the main incision in 5 eyes, and both irrigation port and main incision in 2 eyes.

Conclusions:

All dynamics ( i.e. outflow, leakage, cessation of leakage) can be directly observed during the hydration. The cessation of continuous leakage may be a criteria for adequate wound integrity. However, the technique may be difficult for some surgeons, since one of the hands is blocked with the irrigation mode.
