... Common Vision Conditions Hyperopia Farsightedness (Hyperopia) Hyperopia or "farsightedness" occurs when the eye is "too short" for its own focal length and focused light falls on a focal point behind the retina. People who are hyperopic need help seeing objects up close. Eyeglasses or contact lenses can easily correct this condition.

Farsightedness or hyperopia means objects are seen clearly far away but are blurry close up. In this case, the eyeball is too short for the lens to focus a clear image on the retina.
  • More than half of all patients who wear glasses are farsighted. Vision "screening" commonly done in schools, may not be adequate to detect or diagnose farsightedness accurately. You may be farsighted if you:
  • Have difficulty concentrating and maintaining a clear focus on near objects.
  • Suffer from eye strain, general tension, fatigue or headaches after close work.
  • Have aching or burning eyes.
  • Have poor reading ability or need to hold reading material away from your eyes.
  • Become irritable or nervous after prolonged concentration.

E-MAIL: kblum@jhmi.edu Hopkins Offers Non-Laser Correction Farsightedness Surgeons at Johns Hopkins' Wilmer Eye Institute are now offering conductive keratoplasty, or CK, to correct low-level farsightedness in selected patients over age 40. The procedure, approved in April by the U.S. Food and Drug Administration, is the first non-laser treatment for hyperopia, a condition in which people can see objects far away but have trouble focusing on those nearby. It is an outpatient surgery performed under local anesthesia in just a few minutes . Unlike laser treatments, which use light waves as an energy source, CK uses radiofrequency waves, a form of electromagnetic energy, to re-shape the peripheral cornea. The energy is similar in some respects to the microwaves that power CB radios and cell phones. CK employs a pen-shaped instrument with a tip as thin as a human hair that releases the radiofrequency energy. The tip is applied in a circular pattern on the outer layer of the front of the eyeball to shrink small areas of tissue. The result is a constrictive band of tissue, similar to a tightened belt, that increases the overall curvature of the cornea. "Nearly 95 percent of patients with low to moderate ranges of farsightedness achieve normal or near-normal vision after the procedure," says Terrence P. O'Brien, M.D., medical director of the Wilmer Laser Vision Center in Lutherville, Md.

A new laser technique for farsightedness Tuesday, December 05, 2000 By Anita Srikameswaran, Post-Gazette Staff Writer Local eye surgeons are now offering an incision-free laser technique for farsightedness. Dr. Deepinder Deepinder Dhaliwal shows patient Claire Keyes of Point Breeze how a laser system would correct her farsightedness at the UPMC LaserVision Center. ( In laser thermokeratoplasty, or LTK, the laser beam heats a ring of tissue around the center of the eye to tighten collagen fibers there. That squeeze steepens the central cornea and corrects hyperopia, a condition in which objects are blurry whether close up or far away. Each eye is treated in a few seconds. Unlike Lasik, the new technique doesn't cut a flap into the cornea or remove any tissue, so the risk of complications is quite low. "You just put your chin in a chin rest and the laser does its thing," said Dr. Deepinder Dhaliwal, chief of refractive surgery for the Laser/Vision Center at the University of Pittsburgh Medical Center. "It's very, very safe." About 77 million people in the United States are farsighted, making the condition slightly more common than myopia or nearsightedness. In June, the Food and Drug Administration approved the laser equipment, made by Sunrise Technologies, for the "temporary" reduction of hyperopia from +0.75 up to + 2.5 diopters in patients aged 40 and older.

Farsightedness treated with investigational
laser techinique at stanford
STANFORD Ophthalmologists at Stanford have begun a clinical trial of a new laser treatment to correct vision in patients who are naturally farsighted, with or without astigmatism, or who have become farsighted as a result of earlier eye surgeries.
The trial is believed to be one of the first in the United States to test the value of the technique in people with these vision problems, said Edward Manche, MD, director of refractive surgery at Stanford Hospital and Clinics, part of UCSF Stanford Health Care.
The technique is called LASIK, which stands for laser in-situ keratomileusis.
"There were many people who had [an earlier procedure known as] radial keratotomy and who are farsighted because of the unrecognized consequences of the progression toward farsightedness. Up until now, there was nothing we could offer them," said Manche, an assistant professor of ophthalmology and the principal investigator in the new trial.
"This offers a solution to patients who have had radial keratotomy in the past and are farsighted as a result," Manche said.

Stanford testing experimental treatment for farsightedness
STANFORD A Stanford researcher is conducting the first U.S. clinical trials of an experimental method to correct farsightedness. The fast, painless outpatient procedure uses radio-frequency energy to reshape the front of the eye. For patients treated thus far, the technique has provided immediate improvement in vision, said Edward E. Manche, MD, assistant professor of ophthamology and director of cornea and refractive surgery at Stanford University School of Medicine. Vision continued to sharpen in the weeks after the procedure as the eye settled into its new shape, Manche added. Since starting the trial about six weeks ago, he has treated four patients, all of whom now have at least 20/25 vision, Manche said. Before the therapy, none had vision better than 20/40 the limit to drive legally without corrective lenses, Manche said. On Sunday, Manche will present preliminary data on these patients at the annual meeting of the American Society of Cataract and Refractive Surgery, held in Seattle, Wash. He is the national medical monitor of a four-center Food and Drug Administration trial of the technique, which has been previously tested only in Italy and Mexico.

Definition
The term presbyopia means "old eye" and is a vision condition involving the loss of the eye's ability to focus on close objects. Description
Presbyopia is a condition that occurs as a part of normal aging and is not considered to be an eye disease. The process occurs gradually over a number of years. Symptoms are usually noticeable by age 40-45 and continue to develop until the process stabilizes some 10-20 years later. Presbyopia occurs without regard to other eye conditions. Causes and symptoms In the eye, the crystalline lens is located just behind the iris and the pupil. Tiny ciliary muscles pull and push the lens, adjusting its curvature, and thereby adjusting the eye's focal power to bring objects into focus. As individuals age, the lens becomes less flexible and elastic, and the muscles become less powerful. Because these changes result in inadequate adjustment of the lens of the eye for various distances, objects that are close will appear blurry. The major cause of presbyopia is loss of elasticity of the lens of the eye. Loss of ciliary muscle power, however, is also believed to contribute to the problem. Symptoms of presbyopia result in the inability to focus on objects close at hand. As the lens hardens, it is unable to focus the rays of light that come from nearby objects. Individuals typically have difficulty reading small print, such as that in telephone directories and newspaper advertisements, and may need to hold reading materials at arm's length. Symptoms include headache and eyestrain when doing close work, blurry vision, and eye fatigue. Symptoms may be worse early in the morning or when individuals are fatigued. Dim lighting may also aggravate the problem.

http://www.hyverlaser.com/vision/farsightedness.shtml
In farsightedness (Hyperopia), light rays come to focus behind the retina . This delayed focusing of light occurs either because the cornea has an abnormally low curvature (and therefore does not focus light quickly enough) or the eye is too short. With farsightedness, many people do not need glasses for a part of their life, because they can compensate by automatically focusing with their lens inside their eye. As they age, and their lens subsequently weakens, they first need reading glasses and then eventually distance glasses as well. The following procedures may be used to correct farsightedness: In correcting farsightedness with the laser, the cornea is made more curved and therefore more powerful in focusing.

Farsightedness
Definition: Farsightedness is difficulty seeing objects which are nearby.
Alternative Names: Hyperopia
Causes, incidence, and risk factors: Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak. Farsightedness is often present from birth, but children can often tolerate moderate amounts without difficulty and most outgrow the condition. As aging occurs, glasses or contact lenses may be required to correct the vision. A family history of farsightedness is a risk factor.
Symptoms:
Signs and tests: A general eye examination to evaluate hyperopia may include:
Treatment: Farsightedness is easily corrected with glasses or contact lenses. Surgical techniques are available for correcting farsightedness and can be used for those who do not wish to wear glasses or contacts.
Expectations (prognosis): The outcome is expected to be good.

What is Nearsightedness (Myopia), Farsightedness (Hyperopia), and Astigmatism?
The eye "sees" by focusing light rays from an object of regard on to the retina. The retina is a thin layer in the back of the eye that transmits visual signals to the brain. When the light is not properly focused on the retina, refractive errors occur requiring glasses, contact lenses, or refractive surgery to make vision clearer.
Myopia (Nearsightedness)
Myopia or nearsightedness means you can see better up close than you can at far distances as shown on the left hand photograph below. Myopia occurs because the eye is larger than average. The illustration on the right below shows the normal length of the eye shown by the dotted line. Since myopia is caused by the eye being longer than average, the light that is focused in the eye lands in front of the retina rather than on the retina. Nearsighted glasses, contact lenses, and laser refractive surgery are all used to move the image from in front of the retina to on the retina itself! For more information about laser refractive surgery to correct nearsightedness, see our Refractive Surgery page!

92. Farsightedness, View From Arms Length
The eye can usually adjust focus very quickly. Hyperopia, farsightedness, is presentwhen the eye has too little focusing power when in a relaxed state.
http://www.ohioeyedocs.com/farsightedness,_view_from_arms_length.htm
In July we discussed the importance of evaluating children to rule out significant vision problems. We feel it was a timely topic, considering the new school year was fast approaching. Next, we decided to discuss the most commonly occurring vision problems. This month, hyperopia. A discussion of the eye must begin with a description of what is normal. A person should be able to relax and gaze into the distance and see clearly. The cornea, which is the front surface of the eye, and the lens, which is inside the eye, combine to provide the exact focusing strength to image a distant object upon the retina of the eye. The retina, at the back of the eye, acts like the film in a camera and transmits the information to the brain where "vision" actually occurs. Hyperopia is due to a combination of factors. Heredity, nutrition, and maternal health during pregnancy may all play a part. A child of two hyperopic parents has the deck stacked against him. Even parents without hyperopia may provide a combination of genetic information to produce a hyperopic child. In truth, a small amount of hyperopia is a normal state for young children. This normally does not create problems for children as they have a very good ability to compensate. In most cases it also decreases during the growth process. the most important factors related to farsightedness are the amount which exists and the degree and type of visual demands in a person's day to day activities. Hyperopia has not been studied studied as extensively as myopia. This is due to its relative lack of impact on peoples' lives when present in small amounts and also due to its lower incidence in greater, problematic amounts. We are still searching for the exact factors which cause the system to malfunction.

What if I am farsighted? Farsightedness treatment is now in FDA clinical study and able to correct up to 6 diopters with the laser. Call our office for the latest information on this exciting new capability. What range of nearsightedness can be treated with laser? In the U.S., the excimer laser PRK procedure is approved for the treatment of nearsightedness within the range of -1.00 to -6.00 diopters, and astigmatism from 0.75 to 4.00 diopters. LASIK may be a good surgical option to treat low, moderate and high levels of nearsightedness. Dr. Plager has successfully treated up to 14 diopters with the laser. Do I need to take time off from work? With PRK , rarely will you want to return to work the next day. The visual results of the PRK surgery are not quite instantaneous, it may take several days for the vision to become clear enough to drive. LASIK generally provides good vision the next day, enabling patients to return to work. Can my vision return to its original level after surgery? Some patients experience a regression of effect following surgery, but not to the preoperative level. Fine-tuning or enhancement surgery can often be done (either with

Main News Office: STANFORD, Calif. – The federal Food and Drug Administration has approved on Friday a new, laser-less procedure called conductive keratoplasty (CK) for the treatment of farsightedness, a condition that affects about 20 percent of the U.S. population. Stanford University Medical Center, where the first half-dozen cases in the United States were performed in a clinical trial, is one of the only places in the country to offer the procedure. “CK opens up a whole new way of treating patients with hyperopia (farsightedness),” said Edward Manche, MD, assistant professor of ophthalmology and director of cornea and refractive surgery at Stanford University’s School of Medicine. “This non-cutting, laser-less procedure has some real advantages. It’s extremely fast – about three minutes per eye. It puts treatments on the periphery of the cornea, leaving the central portion untouched. And it leaves no scarring in the central part of the cornea.”

Farsightedness, or hyperopia , as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly. Common signs of farsightedness include difficulty in concentrating and maintaining a clear focus on near objects, eye strain, fatigue and/or headaches after close work, aching or burning eyes, irritability or nervousness after sustained concentration. Common vision screenings, often done in schools, are generally ineffective in detecting farsightedness. A comprehensive optometric examination will include testing for farsightedness. In mild cases of farsightedness, your eyes may be able to compensate without corrective lenses. In other cases, your optometrist can prescribe eyeglasses or contact lenses to optically correct farsightedness by altering the way the light enters your eyes.

If the lens in the eye is too weak, or the cornea is too thin, or the eye is too short, it will cause the real image to get formed in beyond the retina. This will cause a blurred image. We would call it farsightedness (hyperopia). Uncorrected, farsightedness basically means you can't see things close up. Since the problem is that the rays aren't converging soon enough, we need to increase the convergence. Farsightedness is usually corrected by placing a converging lens in the front eye. ©1999 Science Joy Wagon

Hyperopia can be present at any age, and is different from presbyopia which occurs over age 40. In young patients with mild to moderate degrees of hyperopia distance vision is typically good, but the patient may experience headaches or eyestrain when reading. Higher degrees of hyperopia may blur distance vision also, and may lead to amblyopia (lazy eye). School vision screenings may often fail to detect hyperopia because they only test distance vision. Hyperopia can be corrected with eyeglasses or contact lenses. Back
