An eye doctor is a person who gives a specialized service related to your eyesight or vision. In general, it is any health care worker involved with eye care, from a single with a minimum amount of formal training to medical practitioners with at least a bachelor’s degree of medical studies. The eye doctor plays a vital role in our society, since he is responsible for the vision of millions of individuals who are treated yearly for various eye problems that range from common problems like blurred vision, nearsightedness and farsightedness to more serious conditions like glaucoma. Since the eye doctor is responsible for the vision of a patient, his responsibility requires him to be meticulous in his work. More often than not, the task that takes an eye specialist most time is determining the eye problem or disease of a patient.
Most of the time, this entails a visual test, which normally consists of a visual examination of a specific region of the visual field. The patient is required to look straight into the lens of the eye through the pupil, hold a finger in front of the pupil for two seconds and then look away slowly. The results of this exam are usually used as a baseline to determine the severity of the condition. Generally, every ophthalmologist follows these three basic methods of diagnosis:
Visual testing An eye doctor uses different methods in order to determine if he has a patient with eye problems like strabismus, myopia (nearsightedness), hypermetropia (farsightedness) or astigmatism. One of these methods includes visual testing and computerized tomography (CT) scan. Computerized tomography scan is often used to check for retinal hemorrhage, but is sometimes used instead of or in addition to visual testing since it can give faster results.
Surgical Treatment The most common surgical procedure that an ophthalmologist performs is laminectomy. In this procedure, the doctor removes a part of the retina called the choroid. This is done to treat severe dry eye, corneal scarring or hemorrhage and to open the eye to correction. Other surgical procedures include scleral buckle repair, choroidal elevation, removal of a portion of the eye’s erythrocyte lining called arthroplasty or treatment of an iris disease called iridotomy. The most common surgical procedure is LASIK eye surgery.
Vision Insurance If you are suffering from poor eyesight and do not have vision insurance, you may need to obtain your own. There are many private health care providers who provide this service. You can go to a vision insurance provider’s website and look for a list of providers near you. Then, call each eye doctor’s office and find out their contact information. Call each one to ask about their fees and what type of coverage they offer.
Visual Field Testing When you visit an ophthalmologist, he or she will perform a visual field test that checks for problems such as convergence insufficiency, hyperopia or myopia (farsightedness), astigmatism and presbyopia (dysopia). These conditions can cause blurred vision, decreased contrast and halos around lights. During the field test, the eye doctor inserts a device called a multifocal monitor into your eye. The monitor records eye movements and produces a score that indicates your visual field deficiency. Many ophthalmologists use this method to prescribe corrective lenses, give vision treatment or conduct a refraction assessment.
