Randomized Controlled Trial Comparative Study Clinical TrialDoes preservative-free lignocaine 1% for hydrodissection reduce pain during phacoemulsification?
To compare preservative-free 1% lignocaine with balanced salt solution (BSS) in alleviating pain during hydrodissection in phacoemulsification cataract surgery. ⋯ There was no significant difference in the pain scores in patients who received BSS or lignocaine 1% solution. Thus, we conclude that hydrodissecting with lignocaine 1% solution does not provide added pain relief during phacoemulsification.
