Presbyopia Eye Surgery
Presbyopia eye surgery is available for many older adults who have found themselves unable to read clearly as they age. The word presbus, meaning gray hair or old age, thus presbyopia, refers to age related far sightedness and affects people who have had, up unto a certain age, very good eyesight but suddenly cannot focus on nearby objects. This vision problem occurs when the crystalline lens gets a little misshapen and begins causing light coming into the eye to focus somewhere behind the retina. This makes the ability to see close objects, especially reading materials, fuzzy and out of focus. The condition particularly begins to show up initially in low light situations. Physical symptoms of the condition may include eyestrain and headaches that occur after lengthy reading sessions.
For some aging adults, there may have been a sense of pride that glasses were never needed and that could translate into a hesitancy to seek an ocular care professional's help. Of course, the decision is a personal one, but once most people get the presbyopia eye treatment that they need, a sense of gratitude emerges that they let go of their pride and did seek help. There will probably be one of two resources that most adults will seek for their treatment needs: one will be an ophthalmologist and the other an optometrist. The ophthalmologist is a medical doctor (MD) who has chosen the specialized practice in the illnesses and diseases of the ocular system. This physician will probably be an ocular surgeon who may also do some limited surgery on neurological issues connected to vision. The optometrist is a college graduate who has four additional years of training in care for the eyes. Either of these professionals can give excellent presbyopia treatment and if the optometrist does suspect a more serious problem exists would no doubt refer his patient to an ophthalmologist for presbyopia surgery consultation.
In the eye doctor's office, the typical battery of eyesight tests will be given to determine the extent of the presbyopia eye surgery that will be required. For example, the very traditional refraction test will be administered which is the eyesight chart on the wall from twenty feet away. This will no doubt be administered through the eyes of that strange looking phoroptor that looks like a submarine conning tower view scope from the movies. The examiner will ask the familiar questions about which lens is better, and then will proceed to give the patient twenty different options as to which are the clearest. There will be a test to check for color blindness and a check for glaucoma which occurs by puff of generated air on the eyeball that can make a person jump out of their seat in surprise. The examiner will look at the movement of the eyeball, looking for how strong the muscles are that move it, and no doubt the doctor will look into the eyeball, from whence many hitherto undiagnosed diseases can be spotted. And a test of peripheral vision will also be administered to ascertain the fullextent of the presbyopia eye surgery that will be required.
If and when the diagnosis is made, the patient may have a number of ocular treatment options open to him or her because the condition is not severe. For the majority of persons, the choice is usually progressive lenses, better known as bifocals. Because sufferers of this condition feel that they need to hold books and other reading materials at arm's length, yet when they do close in work such as handwriting or embroidery they feel eyestrain or headaches, there will be the need for two prescriptive lenses on the eyeglasses: one for the arm's length readings and one for the close in work. Many people today want to shun the appearance of old age and look to blended, or progressive lenses as an answer. These blended type lenses provide ocular treatment without the need for presbyopia eye surgery. Growing older can bring a great sense of insight into the nature of God: "I have been young and now I am old yet I have not seen the righteous forsaken nor his seed begging bread." (Psalm 37:25)
There may only be the need for reading glasses and not presbyopia eye surgery, particularly if a person already wears contact lenses. Many of these types of eye ware can be purchased at a local drugstore for a nominal cost, but if that is not an option because of the kind of work you might be in, consider multifocal contact lenses as a presbyopia eye treatment solution. With these types of contacts, one merely shifts his gaze downward to gain the advantage that reading glasses give. Other people choose to have a contact lens in one eye for distance reading and the other eye's contact for nearby work, and this is called monovision. But this can take away depth perception for some people and actually make others nauseous. It's a question of trying and seeing how your eyes respond, and if the response is not favorable to the patient, perhaps the last option is presbyopa eye surgery.
Finally, there are some presbyopia eye surgery options for those looking for long term eye treatment methods. Very selective laser presbyopia eye surgery might be the answer for some who have this ocular condition, while another type of surgery using radio waves to reshape the cornea might also be an option. Additionally, there is a presbyopia eye surgery that replaces the natural lens with an artificial one to correct the farsightedness. With millions of Baby Boomers coming to retirement age, there will continue to be a race to find techniques to correct this age related condition with minimally evasive surgical techniques.
Myopia Eye CorrectionTreatment for myopia eye correction is available with eyeglasses, contact lenses, or eye surgery. Myopia is nearsightedness; the most common vision diagnosed. Nearly one-third of the population experiences this vision condition. And even more spectacular is the fact that almost 40% of the population will develop nearsightedness at some time in the future. Objects at a distance are difficult for nearsighted people to see. However, things that are up-close tasks like reading or sewing are quite easy to see. A prescription for corrective lenses that redirect light rays to the retina can be the solution for myopia eye correction. This condition is manifested when the eyeball is not round. In fact, it is slightly longer from front to back. The resulting light rays, that are supposed to point directly at the retina, actually point in front of the retina. This focusing anomaly is spawned from an overpowered eye. Basically, the amount of optical power produced is too intense for the length of the eyeball. This super power brings light rays, that are coming from a distance, into focus before they reach the intended destination; the retina. Therefore, things in the distance become blurry.
Vision clarity depends upon how light rays focus on the retina. Myopia eye correction may be able to help this condition. For example, when using a camera, the light focuses on the film which is at the back of a camera. If the light goes anywhere else, the film will not be exposed properly and therefore, there will be no picture taken. The same is true for the way light hits a person's retina. The retina is like the film of a camera. The light must hit the retina in the just the right spot to produce a clear picture. When the light is off target, then there is blurriness. Old wives tales tell us that myopia is caused by using your eyes too much. This has not born out in statistical data. Ophthalmologist call this a refractive error. There are many types of refractive errors; myopia being one type. The others are called hyperopia, astigmatism, and presbyopia. Hyperopia is the opposite of myopia. This is what doctors refer to as farsightedness. Affecting about 25% of people, farsightedness allows people to see very far away. Yet these same people find difficulty in focusing on things that are nearby. Myopia eye correction is accomplished by a prescription for a lens that has been calculated to weaken the eye. When this happens a person can see more clearly in the distance. This solution can come in the form of both glasses or contact lenses.
Astigmatism is a very different type of eye condition. It affects the cornea, not the retina. Whereas, presbyopia happens to everyone. Even people who have never experienced a vision problem before, suddenly start having blurred vision during close-up work or reading. Presbyopia causes people to hold newspapers, magazines, and books at arm's length so that they can get clear focus on the material. Ophthalmologists generally agree that presbyopia stems from increased rigidity of the natural lens inside a person's eyes. Similar to a used elastic band, the lens responsiveness is worn out. Actually the proteins and muscle fibers around the eye seem to change. These changes cause the lens to stop functioning as it once did. Myopia eye correction cannot help in these cases.
Heredity is the usual deciding factor as to whether a person has myopia or not. When a child complains about not being able to see something in the distance, it's a good time to have their eyes examined. As children, the condition develops and continues to advance over time. Usually the condition worsens in people of advanced age. There is actually a term for it: myopic creep. Nearly 2% of the population is plagued by a more severe form of myopia; termed pathologic. Also referred to as degenerative, the condition is normally apparent by age 12. In children who have extremely elongated eyeballs, the eyeball continues to stretch with age with a progressive and potentially severe loss of vision. Myopia is not a disease; however. There is just a shape difference in their eyeball. For people aver the age of 40, myopia can be a real advantage. While others may be getting glasses for reading, they can read perfectly well without them. This means that myopia eye correction would actually bring a disadvantage. "But I wrought for my name's sake, that it should not be polluted before the heathen, among whom they were, in whose sight I made myself known unto them, in bringing them forth out of the land of Egypt." (Ezekiel 20:9)
Myopia eye correction could be the solution for this malady. One type of correction available is an injectable photosensitive drug called Visudyne. The injection taken along with a laser treatment helps to stabilize and even improve this eye condition. Additionally, there is often an abnormal growth of new blood vessels underneath the macula. When coupled with leakage in the back of the eye it is called "Wet" macular degeneration. This affects a person's fine focus ability; making myopia eye correction necessary. There are several options to choose from to correct this condition. Glasses comes in all shapes and sizes. Contact lenses, on the other hand, can come in different lens shades. And then, there is a surgical and treatment option. Whether a person decides on a more permanent solution or to use artificial lenses, seeing is important. Whatever works for the person, is the treatment that should be chosen.
