Surgery to correct refractive errors is becoming increasingly common.
However, in Brazil there are few studies on hyperopia and associations with visual and refractive errors.
The number of people with refractive errors that have not been corrected was estimated at 660 million(10 per 100 people) in 2013.
The most common correction is with progressive lenses, which correct all refractive errors in one single lens.
Refractive errors can be associated with the condition, with frequent cases of anisometropia, astigmatism and amblyopia.
This represented 3.6% of the total of participants of the study, and9.7% of the total of refractive errors found in the study.

Ocular manifestations are: microphthalmos, anterior uveitis, retinopathy in"salt and pepper", cataract,keratopathy and refractive errors.
In a majority of cases, refractive errors can be easily corrected with a pair of eyeglasses, contact lenses or surgery.
The principle ophthalmologic abnormalities described in the literature as secondary to prematurity are ROP, strabismus and refractive errors.
Refractive errors which are not fixed tend to lead to a visual over-exertion and difficulty to focus, headaches and ocular fatigue.
Clinically, astigmatism is commonly seen in combination with other refractive errors such as myopia, hyperopia, or sometimes as mixed.
Causes of refractive errors include aberrations in the shape of the eyeball or the cornea, and reduced flexibility of the lens.
Often the origin is chronic inflammations of the eyelidmargin such as blepharitis, and it may be related to the presence of refractive errors.
