Hyperopia is an eye condition that allows you to have good distant vision, but blurred near vision.
If the eye is too short, the cornea is not curved enough or the lens is too flat, the light rays converge behind the retina. The conversion power of the eye being too low, close objects are then blurred.
This vision disorder is often compensated by the natural lens of the eye, the crystalline lens, which exerts a constant extra effort to focus the light rays on the retina.
Farsightedness beyond the +4.00 diopter mark is often hereditary and generally requires the wearing of glasses. A strong farsighted person has blurred near vision.
For young farsighted people
These prescriptions are not optimal for refractive laser surgery. A young candidate must have good corneal thickness on the periphery of the treatment area to allow the laser to sufficiently bulge the cornea in order to correct all of the prescription. In addition, people with strong hyperopia are more likely to have regression following laser treatment. If the professionals at the IRIS Ophthalmology Clinic notice too many contraindications to laser surgery, they may recommend another type of operation: the Phake intraocular lens.
For farsighted people in their 50s
Strong farsighted people have a better odds with intraocular lenses. Normally, a patient over the age of 50 with severe hyperopia can undergo intraocular lens surgery. These lenses, which replace the lens, allow the rays to converge directly on the retina for good near, far, or near and far vision simultaneously.
There is no “best” treatment for farsightedness. Each patient is different and that is why each assessment is personalized to you. If our professionals do not see almost all of the success factors for your surgery, they will take the time to explain to you why surgery would not be ideal.
There are several types of intraocular lenses for different lifestyles. Some lenses like monofocal lenses allow you to see well at only one distance.
Other lenses such as diffractive multifocal lenses allow you to simultaneously have a good quality of near and far vision.
The evaluation with our optometrists will allow you to clearly identify your needs and allow you to make an informed decision on the lens that best suits your lifestyle.
A person with hyperopia ranging from +1.00 to +2.00 can generally see well near and far thanks to the accommodation of their natural lens. However, after constant exertion, this person will likely experience eyestrain with headaches.
For hyperopia ranging from moderate to advanced (+3.00 and more), accommodation of the lens is usually not sufficient and glasses are necessary. Without glasses, vision is often blurred, near and far.
ULTRALASIK surgery corrects farsightedness by sculpting a kind of “gutter” all around the treatment area on the cornea. In this way, it is possible to give a rounder shape to the cornea, helping the light beams to converge better on the retina.
Uncorrected hyperopia requires constant effort from the lens. This is why, in some cases, the professionals at the IRIS Ophthalmology Clinic will explain to you that correcting all of the hyperopia could make you myopic.
The reason is simple: your lens has become accustomed to constantly straining to allow you to see well up close and has developed a residual accommodation. This means that your lens is no longer able to be fully at rest and remains in a slightly contracted shape. Fully correcting farsightedness without considering residual accommodation could make you slightly nearsighted.
Our team could then suggest that you keep a slight farsightedness at the corneal level, just enough to be compensated by the residual accommodation of your lens, which would give you a so-called “plano” vision.
