  Dear Editor

  As cataract surgeons move toward toward less invasive procedures including topical anesthesia, Friedman et al.[1] have done a research on the patient's perspective.

  Their results surprisingly showed that patients preferred retrobulbar blockade anaesthesia over topical anaesthesia in preparing for cataract surgery, raising the question whether ophthalmologists are moving in the proper direction. However, for informed consent patients need to be told not only the risks and benefits of the cataract surgery itself but also the risk and benefits of the alternative anesthesia modalities.[2] While rare, complications of retrobulbar anesthesia injection can be devastating; for example, inadvertent globe perforation,[3] blindness from the injection into the optic nerve,[4] or apnea resulting from subarachnoid injection of the anaesthetic agent.[5-6] Had the patients been informed of these uncommon but serious complications, their preferences might have been altered and the study results might have been different.
