The eye is a delicate organ, requiring extreme care before, during and after a surgical procedure. An expert ophthalmologist must identify the need for specific procedure and be responsible for conducting the procedure safely. Many university programs allow patients to specify if they want to be operated upon by the consultant or the resident / fellow.
Proper anethesia is a must for any eye surgery. Local anesthesia is most commonly used. Retrobulbar and peribulbar techniques for infiltrating the local area surrounding the eye muscle cone are used to immobilze the extraocular muscles and eliminate pain sensation. Topical anesthesia using lidocaine topical gel is preferred for quick procedures. In topical anesthesia, patient cooperation is a must for a smooth procedure. General anesthesia is recommended for children, traumatic eye injuries, major orbitotomies and for apprehensive patients. Cardiovascular monitoring is preferable in local anesthesia and is mandatory in general anesthesia. Proper sterile precautions are taken to prepare the area for surgery, including use of antiseptics like povidone-iodine. Sterile drapes, gowns and gloves are a must. A plastic sheet with a receptacle helps collect the fluids during phacoemulsification. An eye speculum is inserted to keep the eyes wide open. For anxious patients, supplementation with a facial nerve block using lidocaine and bupivacaine is recommended.
