The eye can be examined with relative ease as to both its function and its structure. A practical examination consists of the capability to move in the orbit and the response of the student to light and lodging.
The function of the eye might be evaluated in several methods. The client may be asked to determine illuminated letter or items of differing sizes on exactly what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in numerous ways. Stress within the eyeball is measured by a "tonometer." In specific diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye issue may have other problems as well. Typically other physical conditions are main and impact the eye as a effect. The appearance of the eye can notify the physician and the patient to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.
One's reliance on sight is emphasized when one faces a possible or short-term irreversible loss of this essential sense. When corrective measures are looked for, specific forms of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some individuals are bothered with the truth that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to encourage decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is fixed completely.
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 surgical treatment is to produce a threadlike, rounded "flap" in the cornea using 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.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Probably, the main reason why this type of eye surgery has become well accepted is since many of its cases had actually succeeded.
In spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most sensitive part of the eye

2. It is not a best treatment
LASIK eye surgical treatment may remedy your vision but it does not necessarily imply that it can provide you a ideal vision. Even this article if statistical reports reveal that 70% of the patients may have 20/20 vision, this does not necessarily mean they have ideal vision.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the perfect eye surgical treatment the way a lot of individuals see it

Often other physical conditions are main and impact the eye as a consequence. The look of the eye can signal the client and the physician to troubles in some disruptions of other parts of the body even before other signs present themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another form of vision correction.
