The eye can be examined with relative ease as to both its function and its structure. A practical evaluation consists of the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be checked in a number of methods. The patient may be asked to determine illuminated letter or things of varying sizes on what is known as the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In specific illness, particularly in glaucoma, the stress in the eyeball is increased significantly.
However, it must be well kept in mind that a patient with an eye issue may have other issues as well. Often other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can signal the client and the physician to troubles in some disruptions of other parts of the body even before other symptoms present themselves.
One's reliance on sight is stressed when one deals with a short-lived or possible irreversible loss of this vital sense. Thus, when corrective measures are looked for, specific kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are bothered with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another type of vision correction. The only distinction is that with this type of surgery, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The main function of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade known as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling better the eye to direct more light into the retina.
Appeal vs. Disadvantages

Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgical treatment the method many individuals see it
On the other hand, the assessment of the structural part of the eye might be made in several ways. It must be well kept in mind that a patient with an eye issue may have other issues. Often other physical conditions are primary and impact the eye as a consequence. The look of the eye can alert the client and the physician to problems in some disruptions of other parts of the body even prior to other signs provide themselves.
