Hyperopia (Farsightedness) Treatment - Refractive Surgery


Treatment of hyperopia or the farsightedness is getting a refractive surgery for vision correction, during the surgery procedure the shape of cornea is changed as per requirements. Read below to understand what hyperopia is and why the treatment of hyperopia is essential?

The hyperopia of the farsightedness precludes seeing close objects. When hyperopia is stabilized, it is possible to consider a transaction relating to refractive surgery.

Farsightedness VS Normal Eye


Hyperopia: the opposite of myopia

Contrary to myopia , the hyperopia is the result of too short distance between the front and back of the eyeball, or a lack of curvature of the cornea. Result, near objects is blurry because the image focuses behind the retina and the hyperopic meeting so difficult to see up close.

Hyperopia: why you need to treat it

Sometimes the difficulties of developing the farsighted are offset by the contraction of certain muscles of the eye, which then increases the curvature of the cornea. In this case, the hyperopic encounter fewer difficulties but this work may cause further muscle symptoms including eyestrain, headaches, difficulty in performing precision work. To overcome these additional effects of hyperopia, you need a hyperopia treatment

Hyperopia: stabilizes around age of 40 years

The hyperopia occurs in childhood, and then fades during growth to return in adulthood. But the farsightedness develops several years before stabilizing at about 40 years. Therefore any intervention is preferable to adulthood, ideally from the quarantine.

Hyperopia: the treatment

The treatment of hyperopia based on a vision correction surgery know as refractive surgery or refractive error correction. It involves removing a portion of the cornea: a ring device of about 5-6 mm internal diameter and 8-9 mm external diameter and 30 to 100 microns thick. This is equivalent to removing 5 to 17% of the surface of the cornea. This removal causes the ring bulge the center of the cornea, thereby correcting the path of light rays through the eye. It is used today for this operation the keratectomy or LASIK.

In practice, the procedure is done in the operating room, but a numbing eye drops in the eye is sufficient for the practice of surgery. After surgery, the patient is twenty minutes in the service and then he can go home together.
