The eye can be examined with relative ease as to both its function and its structure. A functional evaluation includes the capability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye may be tested in several methods. The patient might be asked to determine illuminated letter or objects of differing sizes on what is called the Snellen chart.
Conversely, the assessment 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, specifically in glaucoma, the tension in the eyeball is increased noticeably.
Nevertheless, it should be well kept in mind that a patient with an eye issue might have other issues as well. Often other physical conditions are main and affect the eye as a effect. The look of the eye can notify the patient and the doctor to troubles in some disturbances of other parts of the body even prior to other symptoms present themselves.
Consequently, one's reliance on sight is emphasized when one deals with a short-lived or possible permanent loss of this vital sense. Thus, when restorative measures are looked for, certain types of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are bothered with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to motivate reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgery, the refractive errors in the cornea are permanently changed. This can be done utilizing an "excimer laser."
The main purpose of this surgery is to produce a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling much better the eye to direct more light into the retina.
