Orthokeratology

Orthokeratology, also known as ortho-k, is a special non-surgical vision correction procedure involving special gas permeable contact lenses that are worn each night while you sleep, to gently reshape your cornea and correct your vision. The cornea is the front part of your eye that helps shape light as it enters. If the cornea is not shaped correctly, images become blurry and hard to discern. Ortho-K gently reshapes your cornea, giving it the proper shape to bend light to give you the best sight possible. The fact that this procedure takes place while you sleep means that each morning, when you wake up, all you need to do is take out your contact lenses and you are able to enjoy improved eyesight up to 20/20 all day.

Many people with mild to moderate nearsightedness, with or without astigmatism may benefit from the use of ortho-k lenses. Since the effects of ortho-k lenses are reinforced only if worn every night, if wear is discontinued, your eyes return to their original shape. Risk for ortho-k is, therefore, quite minimal and ortho-k patients can discontinue at any time without adverse effects. Use of Ortho-k also does not rule out LASIK in the future. Although Ortho-k lenses are primarily prescribed to correct nearsightedness, they also may be used to correct astigmatism, farsightedness and, in some cases even presbyopia.

If you would like to be glasses and contacts free but are not an ideal candidate for refractive surgery either because of age or other eye conditions like dry eyes, you may still benefit from ortho-k.

During your specialized ortho-k fitting, your eye doctor will ensure you are a good candidate for ortho-k lenses and make sure that the lenses are properly fitted for comfort and safety. The eye doctor will begin by obtaining measurements of your “corneal topography.” This procedure is painless and takes only about a minute. This gives the doctor a detailed picture of the unique topography of your eye. Your doctor will then either fit you from an in-office inventory of ortho-k lenses, or may order a custom pair for fitting at a later appointment. The first pair or two of lenses are usually temporary, in order to start the process of re-shaping your cornea. By the third pair, most people can expect to reach their fullest level of vision correction.

The amount of time it takes to begin experiencing a change of vision with ortho-k varies from person to person. Some people may have great vision after a day or two of using ortho-k lenses overnight, whereas those that require a stronger prescription may take up to a few weeks before attaining the full benefit.

It is important to note that Ortho-k lenses are highly specialized and only specially certified optometrists are able to provide fittings for these lenses. For more information, and to see if ortho-k lenses are a suitable solution for you, contact your Fuquay Eye Care doctor today.

Having allergies can mean more than the sniffling and sneezing that most people associate with it. If you have swollen, itchy eyes it could also be a sign of allergies that can come whether you are sneezing uncontrollably or not. At Fuquay Eye Care we can help.

Allergic conjunctivitis is the scientific name for this condition. It is caused, like any allergic reaction, by a mistaken triggering of your body’s immune system. Allergens cause your immune system “panic” causing it to react negatively to things which actually pose no harm to the body at all. Allergens such as pet dander, pollen and dust can trigger this reaction. This allergic reaction releases a chemical called histamine, which makes your eyes dry out and produce more tears. This reaction is meant to flush out foreign objects. The blood vessels in your eyes also become inflamed, which is what gives your eyes their bloodshot look.

Symptoms of an allergic reaction can be quite varied. You may find that your eyes are red and irritated or itchy, that your eyes are sensitive to light or that your eyelids are swollen. In more severe cases, you may even notice a painful, sore or burning feeling in your eyes or suffer from excessive tearing or a runny nose. You may also experience sneezing and stuffy nose.

Many things may cause an allergic reaction. Grass, weed and tree pollen, as well as dust and pet dander are among the best known allergens. Less well known is that it is also possible for a person to be allergic to everyday items such as makeup or perfume, and even contact lenses. Also not well know is that, while it is very common for allergic symptoms to come out immediately upon contact with the allergen, it is also possible for an allergic reaction to present itself as much as four days after original contact with an allergen.

Although allergies usually stop once the allergen is removed, and the eyes return to normal, this is not always possible with allergens such as dust and pollen, since they are just about everywhere. For these and other allergies, eye doctors recommend eye drops either over the counter or prescription. These eye drops should help to minimize the effects of the allergens in your environment. Many of these eye drops are formulated as anti-histamines, meaning that they block histamine from the body. There are also a number of other ways that these eye drops will work to relieve or prevent allergic symptoms.

Artificial tears are also an excellent option to relieve dry eye symptoms caused by allergens. These eye drops are specially formulated to imitate the tears that the allergic reaction has dried up. Artificial tears are mostly by prescription and have proven to perform better in some cases than over the counter eye drops.

Several other ways to reduce or relieve symptoms exist as well. Wearing sunglasses when stepping outside helps block pollen, dust and other outdoor allergens from getting in your eyes. Contact lenses may also irritate your eyes, so try taking those out if nothing else works. Finally, never rub your eyes while experiencing an allergic reaction. No matter how much they itch, rubbing will irritating your eyes further and make things worse.

The most well-known part of a comprehensive eye exam is the basic visionblog_photo_12_31_15 test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:

Myopia or nearsightedness:
In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

Hyperopia or farsightedness:
Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

Astigmatism:
Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

Presbyopia:
Presbyopia is an age-related condition which usually begins to appear sometime after 40. As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances. However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents. In these instances people with hyperopia could use glasses at any distance.
If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.

When women and men consider their overall health, they normally do not even think about the health their eyes are in. But the eyes are counted on more intensely than just about every other part of the body system.
Due to the fact that this is so, it is tremendously important that you take care of the well-being of your eyes so you can continue to depend on them to get you through the day. Of course, there are numerous ways to work at safeguarding your vision, however the one most crucial thing you have to do is get a comprehensive eye exam.

No matter who you are or what your age is, a complete eye exam will go a long way towards ensuring that your sight remains clear and robust. The eye examination can be carried out by any reputable optometrist in your
area. The eye doctor is qualified to give their patients an in depth examination that incorporates various tests we will consider below. If you have not been to the optometrist in more than a year, book a consultation for an eye exam as quickly as feasible. So, let’s take a look at a number of the issues that an optometrist checks for during your examination, and what they will do to treat the problem.

Some of the initial things that an eye doctor will look for during your eye exam is refractive error. Refractive error describes an inaccuracy in the manner that the eye focuses on light. The final consequence of a
refractive error is a reduction of visual acuity (i.e. acuteness or quality of sight). In the event of mild refractive error, patients sometimes decide to leave the situation uncorrected. However, if the problem infringes on the patient’s capacity to perform their every day jobs, then action has to be undertaken. At the time of your eye examination, the optometrist will establish the issue and outline the options for the patient. In many cases, refractive error will be treated by wearing eyeglasses or contacts. In more extreme circumstances, the patient will prefer to have refractive surgery. This can all be clarified more by your qualified optometrist in the course of your eye examination.

Another thing to ponder is the fact that the eye may be predisposed to certain problems, similar to other parts of the body. Most people have heard of the most familiar disorders of the eye, which include glaucoma and diabetic retinopathy. Since these ailments usually display no signs and symptoms in their early stages, it is vital that you maintain an active methodology to avoid them. This can only be accomplished by making a planned visit to have your eyes examined. The eye doctor will have the ability to look for diseases like glaucoma to ensure that you can take the suitable steps to eradicate the disease before it gets any more serious. Even though these diseases are more generally diagnosed in elderly individuals, it is vital to note that there is nonetheless a possibility for eye disease to occur at an earlier age.

There are numerous other disorders that your eye specialist will be checking for during the course of your eye examination. For example, the eye ailment called Amblyopia, or lazy eye, is typified by its subpar sight in an eye that would be typically considered to be normal. Produced by an inadequate stimulation of vision by the optic nerve to the brain, this problem can be worsened if it is not treated straight away by an eye specialist. Your eye specialist will also look for Strabismus, a further eye problem where the eyes do not effectively align. This disorder impedes the patient’s capacity to execute depth perception, and as such ought to be diagnosed by an eye doctor without delay.

Finally, it is important to differentiate between a basic vision screening and an in depth eye exam. Many people trust that by having a registered nurse or primary care doctor provide a vision screening they are sustaining a sufficient level of eye care. What they do not realise, however, is the fact that the vision screening may only include the reading of letters off a chart which vary in dimensions. After bearing in mind the different other evaluations that have been explored above, everyone will appreciate that the vision screening does not take into account the other assorted conditions and ailments that you may endure. Therefore, by having a full eye examination on a consistent basis, you can help ensure that your eyes remain healthy.
