<unk>  is a sophisticated laser eye treatment which is used to treat presbyopia (ageing eyes; progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. 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 due to ageing changes in the eye. It can be used for people who are also short-sighted (myopia) or long-sighted (hyperopia) and who also may have astigmatism. Primarily the treatment is for a condition called presbyopia.<unk>  can be achieved through laser eye surgery, usually performed as LASIK, although surface laser eye surgery PRK or LASEK can be used to produce the effect.<unk>  works by increasing the depth of field of each eye through subtle changes in the optics of the corneal spherical aberration. The increase in depth of field allows for the eyes to be corrected in such a way that the dominant eye is set for distance and intermediate<unk>  while the non-dominant eye sees best in the intermediate to near range. Because of the similarity in the visual performance of each eye in the intermediate range the brain is able to fuse the images between the eyes rendering a binocular visual environment. This is in contradiction to traditional monovision where the image disparity between the eyes is too high for image fusion by the brain and instead the brain needs to apply suppression of the blurred eye in order to perceive a clear visual field. In<unk> , the eyes are effectively working together to allow good<unk>  at near, intermediate and far, without the use of glasses. The effects of<unk>  tend to last between 5 and 10 years but can be further adjusted by enhancement procedures.
