Purpose:
To determine whether lidocaine 1% injected into the anterior chamber during phacoemulsification damaged the corneal endothelium.
Setting:
Ophthalmology Service, University Hospital, San Juan de Alicante, Spain.
Methods:
In 19 eyes of 19 patients, small incision phacoemulsification and foldable lens (AcrySof MA60BM) implantation was performed using topical anesthesia supplemented by lidocaine 1% (0.3 mL) in the anterior chamber. All cases were operated by the same surgeon. Specular microscopy was performed before surgery and 1 and 3 months postoperatively.
Results:
Mean endothelial cell loss was 5.41% +/- 8.50 (SD) at 1 month and 5.93 +/- 8.50% at 3 months.
Conclusions:
The endothelial damage was similar to that described by other authors, suggesting that phacoemulsification surgery can be performed successfully using topical anesthesia supplemented by lidocaine 1% in the anterior chamber.
