Comparison of methods of local anaesthesia used for cataract extraction.
This paper will discuss the various techniques used for the instillation of local anaesthetics (LA) during intraocular (10) cataract extraction. It will be limited to a comparison of peribulbar block, sub-Tenons block and topical plus intracameral anaesthesia alone, as these are those most frequently used at the author's place of work. It will focus on both the surgeons' preferences and the patients' perceptions and comfort pre-, peri- and postoperatively. A description of each technique and the drugs available will be followed with a discussion of the patients' perceptions and pain levels. Included will be a summary of the patients' anxiety levels and the benefits of any sedation. Throughout, general and specific complications will be debated. All will be supported by current, relevant literature.
