Hyaluronidase mixed lignocaine used as Regional anaesthesia in cataract surgery.

DESIGN:A Prospective, interventional, comparative study.

PARTICIPANTS:Three hundred cataract patients were involved in this prospective, interventional and comparative study.

METHODS:Two groups of patients (Group I and Group II) with 150 patients in each. The patients included in this study were examined for

ocular and systemic diseases. The required pre–operative investigations for cataract surgery was done. Post–operative photographs were taken for

documentation. Group I patients had 7.5% Sodium bicarbonate buffered lignocaine and group II patients had Hyaluronidase mixed lignocaine used

as Regional anaesthesia

RESULTS:Time of onset of anaesthesia and akinesia was 6–10 minutes for Group 1 and 5minutes for Group II patients. More number of patients

in Group I had Intra operative complications like Repeat block, Conjunctival Chemosis, Persistant eye movements (akinesia not achieved) and also

Post–operative complications like Ptosis and Lid edema than in Group II. Analgesia was better in Group I than in Group II.

CONCLUSION:All Complications like chemosis, lid edema and ptosis was more in sodium bicarbonate buffered lignocaine group resolved

totally with maximum period being 4 days and one Ptosis resolved in 2 weeks. None of them had visual or systemic side effects. The advantage in

using Sodium Bicarbonate buffered Lignocaine was cost effective safe and is readily available.
