The eye can be analyzed with relative ease as to both its function and its structure. A functional assessment consists of the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye may be checked in several methods. The patient might be asked to identify illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
Alternatively, the assessment of the structural part of the eye might be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In specific illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it needs to be well bore in mind that a patient with an eye problem might have other issues too. Frequently other physical conditions are main and affect the eye as a repercussion.

For this reason, advanced surgeries were established to motivate decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this kind of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
