The eye can be taken a look at with relative ease as to both its function and its structure. A functional evaluation consists of the ability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye might be evaluated in several methods. The patient might be asked to identify illuminated letter or things of differing sizes on what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye may be made in numerous methods. Stress within the eyeball is measured by a "tonometer." In specific diseases, particularly in glaucoma, the tension in the eyeball is increased markedly.
However, it ought to be well kept in mind that a client with an eye issue may have other issues also. Typically other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can signal the patient and the doctor to problems in some disruptions of other parts of the body even before other symptoms present themselves.

For this reason, advanced surgeries were established to encourage decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another type of vision correction. The only distinction is that with this kind of surgical treatment, one's vision is corrected permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The primary purpose of this surgery is to create a threadlike, rounded "flap" in the cornea using a blade known 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.
