Astigmatism Correction – How to Get Rid of Astigmatism

Astigmatism is a very common vision condition which is faced by most people. Most people think it is not a serious vision problem. At certain level, astigmatism has no impacts on vision and does not need special treatment. However, when astigmatism results in distorted or blurred vision, eye discomfort and headaches, astigmatism correction is needed.

What is astigmatism? Astigmatism is a kind of vision disorders (usually blurred vision) caused by distortions in the curved shape of the front surface of the eye (cornea) and/or the curvature of the lens inside the eye. It can also be caused by years of stress and strain on the eyes. The strain on the eyes can weaken the tiny muscles around the eyes. Problems appear when the eyes need to change shape of cornea or lens. An irregular shape of cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.

Astigmatism usually comes together with other vision problems like nearsightedness (myopia) and farsightedness (hyperopia). All of these vision conditions are called refractive errors because they influence how the eyes bend or “refract” light. Now the question is how we can do the astigmatism correction when we have these errors. Below are just a few tips which you can do to heal astigmatism.

You can use a pendulum for astigmatism correction. You just lie on the floor and swing the pendulum over your head. Try to follow and focus on direction where the pendulum moves. This exercise can keep your eyes focused on one object. If you keep doing this exercise, your eyes will have better capability in focusing on a certain object.

When you feel your eyes are tired, you should take a break. Spend a few minutes to relax your eyes. During the break you can have eye exercise by moving your eyes around. You can also look at the yard or green grass outside. Keep your eyes away from your computer monitor if you work with a computer. Relaxation can release the tense of tiny muscles on your eyes. After the relaxation you will recover your vision.

Another treatment for astigmatism is called Orthokeratology (ortho-k). This treatment uses a series of specially designed rigid contact lenses to slowly reshape the curvature of the cornea. What is good about this treatment is that it is painless.

Eye surgery is also another option for treating astigmatism. The surgery usually uses laser. The purpose of the surgery is to reshape the cornea by removing a small part of eye tissue.

What Makes A Good Lasik Candidate?

As one of the most common outpatient vision correction procedures, Lasik surgery is a relatively straightforward process with the treatment itself taking only minutes. Los Angeles eye surgeons and surgeons in the world perform Lasik surgery on approximately one million eyes every year and it is no different than any other surgery

Laser Assisted in Situ Keratomileusis (Lasik) is intended to eliminate or reduce dependency on eyeglasses or contacts. Beverly Hills Lasik surgery has become more and more popular as the decades progress but still Laser Eye Surgery is not for everyone. Alternative surgery procedures like PRK and Lasik are excellent alternatives to glasses and contact lenses for patients suffering from myopia (nearsightedness), hyperopia (farsightedness), and astigmatism as well as a wide range of other vision conditions.

A procedure like this can permanently reshape the cornea, which is the clear covering of the front of the eye with the help of a laser. Most patients do not report any problems after the Los Angeles Lasik laser surgery. There are a wide variety of different optical lasers used in this procedure but common for all of them is that the laser will remove some tissue from the cornea.

Patients who have reached or are close to reaching the age of 40 should consider that their vision may be affected by conditions that cannot be treated with Lasik surgery, such as presbyopia. Patients with certain medical conditions or taking certain medications should not choose Lasik surgery because of the implication that it might give, according to top professional Beverly Hills Lasik surgeons. If you’re pregnant or nursing you will fall out of the ideal candidate classification and as it is advised to wait before considering laser vision correction. Patients with a condition called keratoconus are ineligible for the procedure and so are patients who have high levels of refractive error. Both parties are at a slightly higher risk for post-surgical astigmatism.

Laser vision correction surgery is an extraordinary procedure that has helped thousands of people see better and is an exciting opportunity for anyone who suffers from vision problems. Lasik surgery is the preferred vision correction surgery these days, despite its high cost. This type of surgery is however generally not the best option for older patients suffering from age-related conditions. Often these conditions can’t be treated with the Lasik procedure. To learn more about Lasik and laser eye surgery, contact you local Lasik eye specialists to learn more.

Andrew I. Caster, M.D. has performed over fourteen thousand procedures to correct nearsightedness, farsightedness, and astigmatism. Dr. Caster is widely considered one of the most knowledgeable Lasik surgeons in the United States. Los Angeles Magazine selected Dr. caster as “The Best Lasik Surgeon in Los Angeles” and W Magazine listed him as one of two top Lasik surgeons in the United States.

Understanding Low Vision

For a sighted person, the loss of vision represents much more than a physical impairment. Macular Degeneration and other low vision conditions have contributed to a growing population of people relearning how to live. It means a loss of their accustomed independence: the end of driving to work, reading the local newspaper, even simple pleasures like playing catch. Macular degeneration products and other low vision magnifiers have gave way to life, but not enough. Through a new center based at Wayne State University, a multidisciplinary team of San Diego-area researchers and clinicians has begun work they hope will return a level of autonomy to the growing number of men and women who are facing the limitations of life without sight.

To put it plainly, “Low vision is not no vision.” The definition of blindness is a visual acuity of 20/200 in the best eye with best correction or a visual field of 20 degrees or less. While this definition sounds precise, it is often subjective. An eye specialist who uses an eye chart that does not measure acuities between 20/100 and 20/200 may give “the benefit of the doubt” and declare the patient “legally blind” in order to give the person access to more services. Thus, a person who reads regular print with no aids risks being placed in the same category with people who have a far lesser degree of visual functioning. Why, in an environment where time is measured in milliseconds and gasoline sales are measured in thousandths of a gallon, do we still consider “counts fingers” a viable visual measurement? Why do we continue to cling to an out-of-date standard? Unfortunately, mistakes and misunderstandings still occur. The definition of “legal blindness” is not even the same in all countries. It is simply a random designation arrived at by people with 20/20 vision to determine eligibility for gov. services.

A fact in the field of visual impairment is that a fully sighted person gets 80 percent of his or her information about the world visually. In the case of a low vision person, he or she is still receiving a vast majority of their sensory input by visual means. The point at which 80% becomes 50% or 5% is not something that is easily determined. Attempts to state a “percentage” of vision loss frequently fail to take into account factors other than visual acuity. In my opinion, if an individual demonstrates good visual functioning, this individual’s vision should be given the “benefit of the doubt” when considering educational and rehabilitation programming. Certainly it does not deserve to be ignored as if it were of no importance.

Low vision products help. The most common video magnifier for reading is called a Desktop Video Magnifier. These low vision aids feature a camera mounted over a tray on which the material to be magnified is placed. Some have a built-in monitor and are known as “stand-alone” magnifiers. Others are designed to connect to a television or personal computer.

How to get more information – Ask your Eye MD for a Low vision Specialist. Low vision specialists are licensed doctors of optometry who are trained in the examination and management of patients with visual impairments. A few of them are ophthalmologists with additional training in low vision care. Their services do not offer a cure for the causes of low vision, but they do help the patient learn how to utilize their remaining vision to its fullest potential. Low vision care does not replace the possible need for other treatments such as laser, medication, and surgery.
