Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; [1] progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. [1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction ...
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.
Presbyopia is a typical part of the aging process. [4] It occurs due to age related changes in the lens (decreased elasticity and increased hardness) and ciliary muscle (decreased strength and ability to move the lens), causing the eye to focus right behind rather than on the retina when looking at close objects.

ICD-9-CM. 11.71. MeSH. D020731. MedlinePlus. 007018. [ edit on Wikidata] LASIK or Lasik (/ ˈleɪsɪk /; " laser -assisted in situ keratomileusis "), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.

Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery, where cloudy lens is removed to treat cataract, clear lens extraction is done to surgically correct refractive errors such as high myopia.
Surgery works by changing the shape of the cornea. [5] Far-sightedness primarily affects young children, with rates of 8% at 6 years old and 1% at 15 years old. [9] It then becomes more common again after the age of 40, known as presbyopia, affecting about half of people. [4]
MeSH. D007646. [edit on Wikidata] Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov, a Russian ophthalmologist. It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the phakic ...
Refractive errors are corrected with eyeglasses, contact lenses, or surgery. [3] Eyeglasses are the easiest and safest method of correction. Contact lenses can provide a wider field of vision; however they are associated with a risk of infection. Refractive surgery permanently changes the shape of the cornea. [3]
