About

This study is conducted to determine the efficacy of the cannula atraumatic technique as an alternative to the traditional needle penetrating technique to minimize the incidence of accidental globe penetration and/ or perforation, as the plastic part of the cannula is blunt and is difficult to perforate the normal globe being marble-like in consistency.

Full description

A prospective comparative single blinded randomized controlled clinical study was held in the operating theatre at Research institute of ophthalmology, on adult patients with age group between 18- 80 years of both sexes undergoing anterior, posterior segment or plastic surgeries. two techniques were used in comparison: the atraumatic technique, using a 20 or 22-gauge cannula advanced in the inferior-temporal peribulbar space after local infiltration. The skin and the conjunctiva will be pierced by the cannula and advanced for only 0.5 cm, then the cannula will be advanced blindly. Supplementation using the other sites (medial canthus and superior nasal) as needed.
