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 reaction of the pupil to light and lodging.
The function of the eye may be evaluated in numerous ways. The client might be asked to identify illuminated letter or things of differing sizes on exactly what is referred to as the Snellen chart.
On the other hand, the assessment of the structural part of the eye might be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In specific diseases, especially in glaucoma, the stress in the eyeball is increased noticeably.
Nevertheless, it must be well remembered that a client with an eye problem may have other issues as well. Often other physical conditions are main and affect the eye as a consequence. The appearance of the eye can signal the physician and the client to troubles in some disruptions of other parts of the body even before other signs present themselves.
One's dependence on sight is emphasized when one deals with a possible or short-lived long-term loss of this crucial sense. When restorative measures are sought, specific types of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some individuals are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage reduced usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgery is another type of vision correction. The only distinction is that with this kind of surgery, one's vision is fixed permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The main function 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, allowing much better the eye to direct more light into the retina.
