Principles, Preparation, Local Anesthesia, Postoperative Treatment

The ophthalmologic operations are based on a wide spectrum of indications. On one end we find emergency procedures which cannot be postponed. These comprise severe isolated ocular injuries, involvement of the eye in injuries of the face and ocular injuries in patients with widespread injuries. These patients should usually be operated on within seven hours after the injury, except when it may be assumed that diagnostic or other preparatory measures could improve the surgical results. On the other end of the spectrum we find operations which are performed because of aesthetic indications. There is no urgency to operate and the indications can be discussed between the physician and the patient without being pressed for time. Between the two extremes are the majority of operations which can be postponed by days or weeks, but should be scheduled within a reasonable period of time so that any disadvantages for the patient can be avoided. The urgency of an operation or the possibility to postpone it obviously influences obtaining the informed consent.
