We evaluated the stress during cataract surgery in 15 eyes each following instillation anesthesia, subtenon anesthesia or retrobulbar anesthesia. The intraoperative pain was assessed by questionnaire method. We measured the systolic pressure, serum adrenalin and /3 -endomorphine as parameters of stress. No pain was reported at the start of instillation anesthesia but pain appeared during surgery. Systemic blood pressure rose after start of subtenon or retrobulbar anesthesia. It rose after start of surgery following instillation anesthesia. Serum adrenalin and 13 -endomorphine levels increased after anesthesia in all the 3 groups. They decreased in subtenon and retrobulbar group but remained elevated in intillation group. The findings show that intillation anesthesia induces less stress at the start and more during surgery than the other two modalities.
