    PURPOSE: To determine if adequate anesthesia and akinesia could be obtained using an inferonasal quadrant sub-Tenons anaesthesia for cataract surgery.
    METHODS: The sub-Tenons method of local anaesthesia was used in 50 patients undergoing extracapsular cataract extraction and lens implantation. The technique following was that described by JD Stevens in his study of 50 patients. Posterior sub-Tenons space was approached through a conjunctival incision in the inferonasal quadrant and the anaesthetic solution delivered by an irrigating cannula. The patients were assessed for residual ocular movements just before surgery. Effectiveness of anaesthesia was assessed during surgery using a verbal pain rating score. Scoring was based on the concept of a visual analogue pain score chart.
    RESULTS: Total akinesia was obtained in 20% patients and total anaesthesia in 24% patients. The remainder of the patients had adequate akinesia and anaesthesia to proceed with and complete the surgery.
    CONCLUSION: This method provides satisfactory anaesthesia for cataract surgery.

    Ciliary-block glaucoma occurred in one eye of a 65-year-old-male, following a combined trabeculectomy and extracapsular lens extraction for long-standing angle-closure glaucoma. After pupillary block was excluded as a cause, a posterior capsulotomy resolved the condition. This procedure was repeated successfully when a flat anterior chamber recurred on spontaneous closure of the initial capsulotomy. The ciliary block appeared to be caused by the residual zonule and lens capsule.
