The eye is a fragile and delicate structure that supplies the brain with information about the world that we see. Problems affecting the eye range from infections to impaired vision. The image forming mechanism of the eye consists of the cornea, iris and retina. Recent technology has made Lasik Eye Surgery an easy alternative to failing eyes and eye care problems. Impaired vision is the result of a problem with the retina and the cornea, since the brain receives and interprets electrical impulses generated by images falling onto the retina.

Long sightedness is a visual impairment resulting from too short a distance in the eye between the cornea and the retina. Focusing the eye on close objects becomes difficult. Conversely, short sightedness is caused by too long a focal length in the eye or excessive curvature. As a result, the eye will find it hard to see objects at a distance. Astigmatism is another vision disorder that results if the eyeball is not a perfect sphere. We cannot see clearly if the eye is not in the right shape to allow proper focusing of the image attributes on the retina.

All these refractive errors can be corrected using lenses. The power of these lenses is prescribed by our ophthalmologist after testing our eyes. Many people do not like to wear prescription glasses because they are a hassle for those with active lifestyles and they tend to become an eyesore in social situations. For people looking for an alternative to wearing glasses, lasik eye surgery is a fantastic option. Lasik eye surgery, also known as laser in-situ keratomileusis, lifts a section of the cornea allowing a laser to remove any exposed tissue before the cornea section is replaced. If seeking an eye surgery that is less painful and faster to recover from, lasik eye surgery is the way to go.

The only major qualification is a thick cornea, so it is ideal for most. People with vision impairments, such as short sightedness and mild long sightedness, tend to show the best results. For individuals who do not wish to wear corrective lenses, lasik eye surgery is a viable alternative. It is recommended however that individuals who have had lasik eye surgery have regular eye exams to prevent complications from arising. It is also important to remember that the eyes should not be rubbed vigorously following the procedure.
