Ever-evolving modern day cataract extraction techniques have been accompanied by the use of smaller quantities and less invasive methods of anesthesia. Topical anesthesia is routinely used for phacoemulsification. However, peribulbar block or some modification of it is used for anesthesia in manual small-incision cataract surgery (MSICS) by most practitioners. The authors describe a technique using a combination of 1.5-2 milliliters of anesthetic mixture given subconjunctivally and supplemented with commercially available intracameral anesthetic and mydriatic for MSICS. It is possible to get high level of anesthetic effect and ease of surgery with this technique though there is a small learning curve. Several modifications from topical phacoemulsification like two side ports six o'clock hours apart make this surgery easy to adapt to. No special instrumentation is required. It gives adequate analgesia and anesthesia to complete the surgery. a minimalistic anesthetic approach in MSICS can be used with enhanced safety and by avoiding usual complications of traditional peribulbar and retrobulbar anesthesia.
