According to the study, the use of supplementary lidocaine gel in LASIK can lower pain during and up to 45 minutes after the LASIK procedure.
The researchers compared pain scores of 51 patients undergoing simultaneous bilateral LASIK. One eye was randomly assigned to receive the supplementary lidocaine gel, while the other eye received a carbomer gel control. Both eyes also received the 0.5 percent proparacaine anesthetic.
Researchers assessed pain scores 15, 30 and 45 minutes after LASIK and found significantly lower scores in the lidocaine gel-treated group.
