The eye can be examined with relative ease as to both its function and its structure. A functional evaluation consists of the capability to relocate the orbit and the reaction of the pupil to light and accommodation.
The function of the eye might be evaluated in several ways. The client might be asked to identify illuminated letter or items of varying sizes on what is called the Snellen chart.
On the other hand, the assessment of the structural part of the eye might be made in a number of ways. Stress within the eyeball is determined by a "tonometer." In certain diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it should be well bore in mind that a patient with an eye problem might have other problems too. Frequently other physical conditions are primary and impact the eye as a effect. The look of the eye can notify the patient and the physician to troubles in some disruptions of other parts of the body even prior to other symptoms present themselves.
Consequently, one's reliance on sight is emphasized when one faces a momentary or possible permanent loss of this vital sense. For this reason, when corrective measures are looked for, certain types of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are troubled with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only difference is that with this kind of surgery, one's vision is corrected permanently.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently changed. This can be done using an "excimer laser."
The primary function of this surgery is to produce a threadlike, rounded "flap" in the cornea utilizing a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, permitting much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people must understand. Most likely, the main reason this type of eye surgical treatment has become well accepted is due to the fact that the majority of its cases had succeeded.
In spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Because LASIK eye surgery includes the operation of the retina, which is among the most delicate portions of the eye, many individuals say that the operation can be really dangerous.

2. It is not a perfect procedure
LASIK eye surgery may correct your vision but it does not necessarily indicate that it can provide you a twenty-twenty. Even if analytical reports reveal that 70% of the patients may have 20/20 vision, this try this does not necessarily indicate they have perfect vision.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the ideal eye surgery the way a lot of individuals see it
Conversely, the examination of the structural part of the eye may be made in several methods. It needs to be well kept in mind that a client with an eye issue may have other problems. Often other physical conditions are primary and affect the eye as a consequence. The look of the eye can inform the client and the physician to troubles in some disturbances of other parts of the body even before other signs present themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction.
