Efficacy of 2% lidocaine injection as a topical agent in cataract surgery.
OBJECTIVE
To determine whether 2% Lidocaine injection is an effective topical anesthetic agent for non-phaco small incision cataract surgery.


METHODS
Charity eye clinic supported by Hellen Keller International.


METHODS
One hundred and twenty-five consecutive cataract surgery patients received topical anesthesia with 2% Lidocaine injection solution just 1 and 0.5 minutes prior to non-phaco small incision cataract extraction and intraocular lens implantation. Each patient was asked about pain or pressure sensation during the operation.


RESULTS
The surgeon felt ease in the operations. Many patients (93/125) were comfort during the whole surgery. Only 9 patients' score was above level 3, mostly complained during the nucleus extraction; Among those whose score was level 1-2, 82.6% (19/23) claimed discomfort at middle of the operation (nucleus extraction) or the beginning (creating the conjunctival flap).


CONCLUSIONS
Lidocaine injection solution (2%) was an effective topical anesthesia agent in cataract surgery.
