The eye can be taken a look at with relative ease as to both its function and its structure. A functional examination includes the capability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye might be evaluated in several ways. The patient may be asked to identify illuminated letter or objects of varying sizes on what is known as the Snellen chart.
Alternatively, the assessment of the structural part of the eye might be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In specific diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it needs to be well bore in mind that a client with an eye problem might have other issues also. Frequently other physical conditions are primary and impact the eye as a repercussion. The look of the eye can signal the physician and the client to troubles in some disturbances of other parts of the body even before other signs present themselves.
Subsequently, one's dependence on sight is emphasized when one deals with a temporary or possible permanent loss of this important sense. For this reason, when corrective procedures are sought, specific kinds of vision correction such as contact lenses or eyeglasses 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 reason, advanced surgical operations were established to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this type of surgery, one's vision is corrected permanently.
