Cataractis a congenital oracquired clouding of the lens of the eye. In some literature name "gray barbel" can be found because of the characteristic gray color. Cataract is the main cause of blindness in the world. The development of cataracts is not painful, and the patient himself gradually notices that something is wrong with his vision. Patients usually complain of impaired visual acuity and night drives represent problem for patients as the light of the cars bother them. Besides that, they complain about flashes and the gray picture they see in front of them. Patients usually don't think of cataract when they notice the symptoms above. They go to the ophthalmology clinic because they think their diopters have worsened. When the doctor establishes that the patient has cataract, they make an appointment for the surgery in which they replace the damaged lens with a healthy one. Today, cataract surgery is routine procedure oftenly done and with relatively low incidence of postoperative complications. The procedure is being done under local anesthesia, in ambulance or in daily hospital and the patient is usually discharged home after few hours. One month post surgery, sight of the person is improved for about 95%. Considering that the hospitalization is minimal, health care is focused on education of the patient. That means that nurse needs to be an educator and explain every step of the care to the patient from the very beginning to the discharge of the patient and later, during the regular check- ups. She educate the patient about the procedure itself, potential complications, what to do and not to do after the surgery and how to take care of the eye.
