When Surgery For Farsightedness May Be Desirable
Surgery for farsightedness is not always necessary, in fact in most cases it is usually not necessary at all as eyeglasses or contact lenses can make the needed corrections to one's vision. Farsightedness, or hyperopia, is a condition where distant objects are seen clearly while objects up close are out of focus.
Farsightedness is usually a condition people are born with, and is considered by many to be hereditary. Fewer are born with nearsightedness (myopia), but nearsightedness tends to develop during one's youth, usually over a period of years, though it sometimes can develop more rapidly. Nearsightedness also tends to run in families.
Deformity Of The Cornea - Either condition is due to a structural deformity of the eye's cornea. Unless one chooses prescription glasses or contacts, the cornea must be reshaped surgically to correct the problem. There are several different procedures to choose from, which can be explained by an ophthalmologist, who will also very likely recommend what the best option for correcting one's vision might be.
Surgery for farsightedness involving making changes to the curvature of the cornea and is usually quite straightforward if the correction needed to the curvature is not too great. Recovery time is fairly quick and the patient will usually be able to experience the change in their vision within the first 24 hours. As straightforward as the procedure can be, the eye surgeon usually insists that the patient be generally in good health and that there are no other eye disorders or diseases present which could make the risk of surgery too great.
Anyone who has experience cataract surgery will tell you how quickly the procedure is and how quickly vision improved to normal. Surgery for farsightedness is generally no different, and a patient really has little to fear, even though surgery of any kind always carries with it a degree of risk.
Lens Implants As An Option - One of the problems associated with correcting farsightedness is the curvature of the cornea must be increased, rather than flattened, when nearsightedness is the problem. When the amount the curvature has to be increased is large enough to become difficult, the best option usually becomes one of implanting an intraocular lens; intraocular meaning the lens is inserted inside the outer tissue of eye as opposed to a contact lens which is on the outside, or on the surface of the eye. The implant can usually be accomplished in a relatively few minutes. A small incision is made in the eye, the lens implant is slipped in and positioned correctly, and the eye is then allowed to heal itself. The incision is very small, and stitches are seldom necessary.
Other Types Of Surgery - A procedure known as LASIK surgery is quite common and does not involve a lens implant. LASIK stands for hyperopic laser in-situ keratomileusis, and involves reshaping the cornea of the eye through laser technology. Heat can also be used to change the shape of the cornea, and this procedure, of which there are two types, is called thermal keratoplasty. Both LASIK surgery and thermal keratoplasty are safe procedures although both carry greater risks than does a lens implant.
Not all ophthalmologists will recommend surgery for farsightedness, as the condition is not regarded as a disease, but rather as a mild (in most cases) disorder best handled though the use of corrective lenses. Some people simply do not like wearing eyeglasses for cosmetic reasons or out of vanity. Others have a trade or occupation or are otherwise in a situation where wearing eyeglasses is a major inconvenience, and not everyone finds wearing contact lenses comfortable. If you are farsighted and are looking to have it corrected by means other than eyeglasses, it would be best to consult with an ophthalmologist to see what the best option would be.
