The eye can be analyzed with relative ease as to both its function and its structure. A functional assessment includes the ability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in numerous ways. The client may be asked to determine illuminated letter or items of varying sizes on what is known as the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in several methods. Tension within the eyeball is measured by a "tonometer." In specific diseases, specifically in glaucoma, the stress in the eyeball is increased significantly.
It should be well kept in mind that a patient with an eye issue may have other issues. Often other physical conditions are main and affect the eye as a consequence. The appearance of the eye can alert the physician and the client to difficulties in some disturbances of other parts of the body even before other symptoms provide themselves.
Consequently, one's reliance on sight is stressed when one deals with a short-lived or possible permanent loss of this essential sense. Hence, when restorative steps are looked for, certain types of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to motivate decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment 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 corrected completely.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The main purpose of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, permitting much better the eye to direct more light into the retina.
