Refractive Errors - Hyperopia - VisionChannel hyperopia, or farsightedness, is a disorder where distant objects are usuallyseen clearly, but close ones do not come into proper focus and are blurred. http://www.visionchannel.net/refractiveerrors/hyperopia.shtml
Extractions: Hyperopia Hyperopia, or farsightedness, is a disorder where distant objects are usually seen clearly, but close ones do not come into proper focus and are blurred. This occurs when the eyeball is too short or the cornea is too flat, and light rays entering the eye focus behind the retina rather than directly on it. Hyperopia is often present at birth, but sometimes, vision normalizes as the eyeball lengthens during the growth process. Young adults and children with mild to moderate cases of farsightedness often see close objects clearly because the lens is able to adjust or change its shape. This process is called accommodation . As a person ages, the ability to accommodate often lessens and eyeglasses or contact lenses may be needed.
LASIK For Hyperopia LASIK for hyperopia. The visual benefit of treating farsightedness isavailable at the Indiana Eye Clinic. Some analysts have estimated http://www.indianaeyeclinic.com/LASIKforHyperopia.html
Extractions: LASIK is performed in the Indiana Eye Clinic's outpatient surgery center. Normally, the entire procedure lasts less than 10 minutes, with most patients experiencing an improvement in their vision immediately following the procedure. With the LASIK procedure, most people achieve driving vision within several hours of their treatment. Healing is quite rapid with little or no discomfort.

Extractions: Home Eye Center Surgery Center Meet Doctors ... Contact Us In the normal eye, light bends through the cornea and lens to focus on the retina. With hyperopia (farsightedness - place cursor over image) the eye is shorter (or cornea is flatter) causing the focal point of light to be behind the retina. The image is therefore out of focus on the retina and vision is blurred. 1. A thin flap of cornea is created and folded back. 2. Excimer laser is applied to reshape (ablate) the cornea. 3. The corneal flap is replaced over the treated cornea. 4. The "steeper" cornea now bends light to become focused on the retina. LASIK for Hyperopia Animation Before LASIK treatment, light traveling in the horizontal meridian (in this case blue) is out of focus on the retina. After LASIK treatment (place cursor over image), the "steeper" cornea (arrow) causes light to bend in such a way as to become focused on the retina. Vision is clear. Laser in-Situ Keratomileusis (LASIK) can be used to treat low to high levels of farsightedness (hyperopia) with the goal of reducing or eliminating dependence on corrective lenses. Farsightedness occurs when the cornea is too flat or the eye is too short. This causes the focal point of light to fall behind the retina, rather than on the retina, resulting in blurry near vision. LASIK uses the computer-controlled precision of the Excimer laser to treat the inner tissue of the cornea. The procedure is done using eye drop anesthesia, and while you may feel pressure, the technique is not painful. First, an instrument known as a microkeratome makes a protective flap in the outer layer of the cornea. Next, the Excimer laser sculpts the internal corneal tissue to the correct refractive power by steepening the curvature of the exposed corneal tissue. The "steeper" cornea allows light rays to focus more directly on the retina, thereby reducing farsightedness. After a few minutes of drying, the corneal flap is laid back in its original position. Due to the cornea's extraordinary natural bonding qualities, stitches are usually not required.

Extractions: The FDA has recently approved LASIK surgery for Hyperopia with Astigmatism. Laser in-Situ Keratomileusis (LASIK) can be used to treat low to moderate levels of farsightedness (Hyperopia) with the goal of reducing or eliminating dependence on corrective lenses. Farsightedness occurs when the cornea is too flat or the eye is too short. This causes the focal point of light to fall behind the retina, rather than on the retina, resulting in blurry near vision. LASIK uses the computer-controlled Excimer laser to precisely treat the inner tissue of the cornea. The procedure is done using eye drop anesthesia, and while you may feel pressure, the technique is not painful. First, an instrument known as a microkeratome makes a protective flap in the outer layer of the cornea. Next, the Excimer laser sculpts the internal corneal tissue to the correct focusing power by steepening the curvature of the exposed corneal tissue. The reshaped cornea allows light rays to focus more directly on the retina, thereby reducing farsightedness. The protective flap is then repositioned and seals itself over the treated area. Due to the cornea's extraordinary natural bonding qualities, stitches are usually not required.

Approximately 25 per cent of the general population may be affected. Farsighted individuals see better in the distance than up close because the eye does not effectively focus light. Farsightedness is very common among elementary school-age children and a frequent cause of reading and learning difficulties Refractive errors such as hyperopia are commonly corrected by eyeglasses or contact lenses Refractive surgery is another possibility.

Hyperopia hyperopia, or farsightedness, is a common eye condition. hyperopiaoccurs when the light that enters the eye focuses behind the retina. http://www.penneye.com/html/hyperopia.html
Extractions: Search: PENN Eye Care Refractive Problems Hyperopia Hyperopia, or farsightedness, is a common eye condition. Hyperopia occurs when the light that enters the eye focuses behind the retina . In many cases, the eyeball is to short and so the focal point of light falls behind the retina. The retina is analogous to photographic film in a camera and is located at the back of the eye. People with hyperopia are called farsighted because, in many cases, they can see far away but not up close. In reality, however, the situation is much more complicated. Young hyperopic individuals may be able to see well at all distances and not even know they are hyperopic because the lens of the eye can accommodate. In other words, the eye can compensate for modest amounts of hyperopia. However, this ability to compensate is lost with age and so hyperopia is often discovered as that person ages. People with hyperopia are at higher risk for certain types of eye conditions, including certain forms of glaucoma Hyperopia can usually be treated with glasses, contacts , or r efractive surgery
Extractions: EYE CONDITIONS Conditions Eye Conditions Home Normal Vision Nearsightedness Farsightedness ... Facial Wrinkles :: SITE LAST UPDATED Farsightedness (Hyperopia) Hyperopia, unlike normal vision , occurs when the cornea is too flat in relation to the length of the eye. This causes light to focus at a point beyond the retina, resulting in blurry close vision and occasionally blurry distance vision as well. Usually this condition is undetected until later in life because the young eye is able to compensate for the hyperopia by contracting the internal lens of the eye. (Roll your mouse over the image to change it) Many people are not diagnosed with hyperopia without a complete eye exam. School screenings typically do not detect this condition because they test only for distance vision. Your eye doctor can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Your eye doctor will also check your eye coordination and muscle control, as well as your eyes' ability to change focus. All of these are important factors in how your eyes see. Glasses and contact lenses are used by many for the temporary treatment of hyperopia. However, there are a number of
Patient Education Library - Hyperopia hyperopia (Farsightedness). The curvature. Farsightedness or hyperopiaoccurs when the eye is too small or the cornea is too flat. http://www.cascadeye.com/patienteducation/eyeeducation/hyperopia/hyperopia.htm
Extractions: The cornea and the lens work together to focus images from the visual world on the back of the eye (the retina). If an image is out of focus, it is typically because the overall shape of the eye is incorrect or the cornea does not have the proper curvature. Farsightedness or hyperopia occurs when the eye is too small or the cornea is too flat. When this happens, visual images are focused behind the retina. A person with hyperopia is able to see objects at a distance, but has trouble with objects up close, like books or newspapers. Many people are not diagnosed with hyperopia without a complete eye exam. School screenings typically do not discover this condition because they test only for distance vision.
Hyperopia To correct such vision defects, opticians prescribe corrective lenses. Whata corrective lens does in the case of hyperopia is the following. http://physics.mtsu.edu/~phys232/Lectures/L1-L5/L3/Hyperopia/hyperopia.html
Extractions: Normal human eyes can focus on objects that are from about 25 cm away from the eye ( D min ) up to infinitely far away ( D max ). A hyperopic eye can only see to a near point that has a corresponding distance D min . To correct such vision defects, opticians prescribe corrective lenses. What a corrective lens does in the case of hyperopia is the following. Consider an object that is a distance D o = 25 cm from the eye (the near point for a normal eye). The hyperopic eye cannot focus on this object since it is closer than the eyes near point, which is at a distance D min from the eye. The proper corrective lens is placed (of course) between the object and the eye. The lens takes the object at 25 cm and forms an image which is at the distance of the eyes near point at D min . The eye can then focus on the image of the object as seen through the corrective lens. Most adults with normal eyes eventually become hyperopic since the eyes lens tends to become less flexible as it ages. This decrease in flexibility means that it will be more difficult for the ciliary muscle to accommodate the eyes lens to see objects as they move in from infinity.
