Improve your eyesight with LASIK surgery

Posted in LASIK Surgery on January 21, 2010

Laser vision correction surgery can greatly help people to recover from eye problems such as hyperopia (farsightedness), presbyopia, astigmatism and myopia (nearsightedness). This type of surgery can help patients to get near to perfect vision.

Myopia or nearsightedness happens when the lens and the cornea are too strong, thus causing the light rays to focus in front of the retina. On the other hand, farsightedness or hyperopia occurs when the lens and the cornea are too weak to focus the light rays on the retina.

Astigmatism is generally caused due to refractive error as the cornea is not completely spherical. As a result of this, light gets focused at different locations, thus causing an asymmetric blur. Presbyopia mainly occurs due to ageing eyes, which loses its flexibility after a period of time. Persons suffering from Presbyopia will find it very difficult to focus in on close objects.

All such vision disorders can be corrected with the help of vision correction surgery known as LASIK. This surgery makes use of laser beams to reshape the cornea. It is a painless procedure that combines traditional optical surgery with high-tech excimer laser surgical equipment.

Initially, ophthalmologists prepare the area around eyes with an antiseptic solution to lessen the risk of infection. The patient is also given anaesthetic eye drops to minimise the pain. The procedure is quick and usually gets completed within 10-15 minutes. So, if you face vision problems and utilise external vision correction objects such as contact lenses or glasses, LASIK can help you to get close to perfect vision.
