In the past two decades local anesthesia has emerged as a reliable, safe and cost-effective first choice for cataract surgery in adults. However, the technique is not totally devoid of inherent risks, and requires not only an experienced and well-trained surgeon but also a cooperative patient. Thus, only the patient who is able to communicate, lie still in the supine position, and tolerate their face being covered by a drape is a suitable candidate for local anesthesia. In addition, the preoperative assessment should include particular features of the globe and orbit which may affect the operation as well as a history of allergy to local anesthetics. Finally, it is important to respond to patient preferences and wishes. A careful, patient selection for local anesthesia reduces the risk of surgical cancellation or delay and is essential for patient satisfaction and a successful visual outcome following cataract surgery.
