Farsightedness can be treated by using corrective lenses or refractive surgery. Wearing corrective lenses counteracts the decreased curvature of the cornea or the smaller size of the eyeball.
Types of corrective lenses include:
Eyeglasses-bifocals, trifocals, progressive lenses and reading lenses
Contact lenses- hard ,soft, extended wear, disposible, rigid gas permeable and bifocal
Age-related trouble with vision can be corrected by monovision contact lenses . These contact lenses can be worm intermittently as desired. Another optionis using modified monovison cantact lenses. This type of lens is usually worn in the nondominant eye and a contact lens is worn in the dominant eye. This helps a person to use one eye for seeing nearby objects while both eyes can see distant objects.
Another treatment option for farsightedness is refractive surgery. This involves reshaping the curvature of the cornea.
Methods of refractive surgery include:
Laser-assisted in-situ keratomileusis (LASIK), in which a thin, circular hinged flap cut is made into the cornea. Then using an excimer laser, the surgeon removes layers from the center of the cornea to steepen its domed shape. After this the thin flap of the cornea is repositioned.
Laser-assisted subepithelial keratectomy, in which a surgeon creats a flap involving only the cornea's epithelium. An excimer laser is then used to reshape the cornea's outer layers and steepen its curvature and later the epithelium is repositioned.
Photorefractive keratectomy: this procedure is similar to LASEK, except that only the epithelium is removed.
Conductive keratoplasty (CK), a procedure that uses radiofrequency energy to apply heat to tiny spots around the cornea.
