Subconjunctival Anaesthesia for Conventional Cataract Extraction.
Pak J Ophthalmol Jan ;15(4):152-6.

We present the results of 847 patients, admitted with cataracts over a period of 15 months, from August 1997 to October 1998 who were operated on under subconjunctival anesthesia. Majority of the patients were in the 6th and the 7th decade with a male to female ratio of 1:1.12. We performed extracapsular cataract extraction (ECCE) in 713 and posterior chamber intraocular lens Implant (PC-I0L) in 134 patients. We administered 0.2 to 0.4 ml of 2% injection xylocalne under the topically anaesthetised superior conjunctiva. Analgesia was excellent in 843, while 4 complained of pain during surgery. We supplemented the anaesthesia by facial block in 13 patients. 809 patients were very happy, while 38 were undecided mainly due to postoperative pain. Postoperative pain was relieved by giving diclofenac sodium orally in 782 and by injection in 65 patients. Subconjunctival anaesthesia Is an excellent technique as it is pain-free and avoids all the complications attributed to blind infiltration techniques.
