The eye can be taken a look at with relative ease as to both its function and its structure. A practical assessment consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be tested in several ways. The patient may be asked to identify illuminated letter or objects of differing sizes on exactly what is understood as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye may be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In specific illness, specifically in glaucoma, the stress in the eyeball is increased considerably.
It must be well remembered that a client with an eye problem may have other problems. Typically other physical conditions are primary and impact the eye as a repercussion. The look of the eye can inform the patient and the physician to troubles in some disturbances of other parts of the body even prior to other signs present themselves.
One's dependence on sight is stressed when one deals with a momentary or possible permanent loss of this important sense. Hence, when restorative measures are sought, specific types of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are troubled with the reality that they have some framed lenses or contact lenses in front of their eyes.
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.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgery is another type of vision correction. The only difference is that with this type of surgical treatment, one's vision is corrected permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The main purpose of this surgical treatment is to create a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling much better the eye to direct more light into the retina.
