	Hyperopia - Wikipedia, the free encyclopedia
		An American study published in Archives of Ophthalmology found that nearly 1 in 8 (12.8%) children between the ages of 5 and 17 have hyperopia [1], and a recent Polish study found that 1 in 5 (21%) students between the age of 6 and 18 were hyperopic [2].
		Minor amounts of hyperopia are sometimes left uncorrected, however, larger amounts may be corrected with convex lenses in eyeglasses or contact lenses.
		Hyperopia is sometimes correctable with various refractive surgery procedures.

	LaserMyEye :: Encyclopedia :: Hyperopia
		More properly called "hypermetropia", hyperopia is caused by shortening of the eyeball, which causes light entering the eye to "overshoot" the retina (back of the eye), resulting in an inability to focus properly on objects near at hand.
		Hyperopia is one of three types of refractive error: the two types of spherical refractive error, hyperopia and myopia (these are mutually exclusive - you are either one or the other) and cylindrical refractive error, called astigmatism.
		In hyperopic procedures it is necessary to steepen the cornea by lasering primarily the peripheral part of the cornea (eg roughly a doughnut profile).

	Hyperopia
		Hyperopia (farsightedness) is the condition of the eye where incoming rays of light reach the retina before they converge into a focused image.
		If the hyperopia is not too severe the lens may be able to accommodate and bring the image back onto the retina.
		Hyperopia is usually present at birth, and there is no known way to prevent it.

	Refractive Errors - Hyperopia - VisionChannel
		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.
		Hyperopia is often present at birth, but sometimes, vision normalizes as the eyeball lengthens during the growth process.
		Hyperopia results when the eyeball is too short or the cornea is too flat and the lens is unable to adjust its shape to see close objects clearly (the process called accommodation).

	Farsightedness (Hyperopia) - MyClearVision (Site not responding. Last check: 2007-10-29)
		Hyperopia or farsightedness is very common, affecting up to 62% of people over the age of 40.
		Because hyperopia or farsightedness seems to get worse with age, it is often confused with presbyopia.
		Hyperopia or farsightedness requires a convex corrective lens (glasses or contact lenses), which is written as a "plus" number in your prescription.

		Hyperopia has proven to be more difficult to treat surgically compared to myopia.
		Farsightedness, or hyperopia as it is medically termed, is the ability to clearly see objects at a distance but not those up close.
		A person with hyperopia is able to see objects at a distance, but has trouble with close objects like books or newspapers.

	Hyperopia (nearsightedness) and correction with Lasik operation
		In hyperopia, light rays from a distant object converge and focus on the retina.
		In theory, hyperopia is the inability to focus and see the close objects clearly, but in practice many young hyperopics can compensate the weakness of their focusing ability by excessive use of the accommodation functions of their eyes.
		In refractive hyperopia the size of the eye is normal, but the refractive power of the lens is less than normal.

	Hyperopia (Site not responding. Last check: 2007-10-29)
		Hyperopia (i.e farsightedness) is much less common than myopia or emmetropia.
		In contrast to myopia, hyperopia occurs when the eye is too short for the power of its optical components.
		In hyperopia, the cornea is not steep enough and light rays hit the retina before they come into focus.

	Hyperopia or Farsightedness Information
		Hyperopia is a refractive error where people are able to see distant objects clearly but objects up close seem blurry.
		There are several treatments for hyperopia including eyeglasses, contact lenses, and eye surgery.
		Like treatments for myopia, treatments for hyperopia are designed to refract a correct amount of light into the eyes through either corrective lenses or reshaping of the cornea through surgical and non-surgical methods.

	Hyperopia (Site not responding. Last check: 2007-10-29)
		Hyperopia, or ‘farsightedness’, is a common eye condition.
		People with hyperopia are called ‘farsighted’ because, in many cases, they can see far away but not up close.
		However, this ability to compensate is lost with age and so hyperopia is often ‘discovered’ as that person ages.

	Hyperopia
		Hyperopia or farsighted is a condition in which the eyes must focus to see at a distance.
		However, if the amount of hyperopia is significant two things will happen; first the eyes will use excessive effort to keep the images clear at distance and the excessive accommodation will cause the eyes to over-converge.
		Hyperopia is correlated with ocular fatigue and learning disorders.

	Hyperopia / Long Sightedness
		Hyperopia or Long sightedness, is a common vision problem, affecting almost a fourth of the population.
		Long sightedness or hyperopia, occurs if a persons eyeball is too short or when the cornea is too flat when compared to the normal eye.
		Young people with mild to moderate hyperopia are often able to see clearly because their eyes can adjust, or accommodate to increase the eye’s focusing ability.

	Hyperopia or Farsightedness - From the Cleveland Clinic
		The occurrence of hyperopia increases with age; At least half of all persons over the age of 65 have some degree of farsightedness.
		Hyperopia is a refractive error, like astigmatism and nearsightedness (myopia).
		An even newer procedure for correcting mild hyperopia is the implantation of plastic corneal rings called Intacs, which also alter the shape of the cornea.

	USAEyes.org - Hyperopia Correction Difficulty with LASIK, IntraLASIK, PRK, LASEK, Epi-LASIK, CK, P-IOL, RLE, etc.
		Hyperopia is significantly more difficult to predictably and reliably correct than myopia (nearsighted, shortsighted).
		Hyperopia with astigmatism is a most challenging refractive surgery correction.
		Hyperopia correction of more than about 3.00 diopters with conventional or custom wavefront LASIK, IntraLASIK, PRK, LASEK, LTK, and CK is very difficult to correct successfully without inducing additional problems or without experiencing rapid regression.

	Laser thermal keratoplasty helps correct hyperopia (Site not responding. Last check: 2007-10-29)
		While target correction was attained more frequently in patients with low hyperopia, equal or greater improvement in vision was achieved in patients with moderate hyperopia, and these patients were equally satisfied after treatments with the holmium laser, reported Manus C. Kraff, MD, professor of clinical ophthalmology, Northwestern University, Chicago.
		The enrollment criteria included preoperative hyperopia of 0.75 to 2.50 D. In this study, low hyperopia was defined as 0.75 to 1.99 D, and moderate hyperopia at 2 to 2.50 D. All patients were older than age 40 and had a stable refraction.
		The refractions were stable when defined by a change of less than or equal to 1 D of manifest spherical equivalent between two refractions performed at least 3 months apart in at least 95% of cases.

	eMedicine - Hyperopia, Conductive Keratoplasty : Article by Manolette R Roque, MD (Site not responding. Last check: 2007-10-29)
		Hyperopia, commonly referred to as farsightedness, is an error of refraction (EOR) in which an individual may not have any difficulty seeing objects that are distant but may have problems focusing on objects that are near.
		Farsightedness (hyperopia) is often confused with presbyopia, which is a normal development of the aging process.
		Relevant Anatomy: In hyperopia, the axial length (measurement of the most anterior part of the cornea to the most posterior part of the sclera) of the eyeball is generally shorter than normal and/or the corneal diopteric strength is weaker (flatter curvature).

	Hyperopia (Farsightedness) Correction Surgery
		At the present moment surgical techniques for the correction of different degrees of hyperopia are very safe and predictable.
		For hyperopia greater than 6 diopters a Phakic Lens or Implantable Contact Lens (ICL) is preferred.
		An excellent way to correct hyperopia over 6 diopters is to place a corrective lens inside the eye.
