The eye can be analyzed with relative ease as to both its function and its structure. A practical examination consists of the ability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in several ways. The client may be asked to determine illuminated letter or things of differing sizes on what is understood as the Snellen chart.
On the other hand, the assessment of the structural part of the eye may be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In certain diseases, particularly in glaucoma, the stress in the eyeball is increased noticeably.
It needs to be well kept in mind that a client with an eye issue may have other problems. Typically other physical conditions are main and impact the eye as a effect. The appearance of the eye can signal the patient and the physician to difficulties in some disturbances of other parts of the body even before other signs present themselves.
One's reliance on sight is highlighted when one deals with a momentary or possible irreversible loss of this crucial sense. When restorative steps are sought, particular types of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some individuals are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgery is another kind of vision correction. The only difference is that with this type of surgery, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The primary function 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, allowing better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that people must know. Probably, the main reason this kind of eye surgical treatment has ended up being well accepted is since many of its cases had actually succeeded.
In spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation used to the most delicate part of the eye
Because LASIK eye surgery includes the operation of the retina, which is one of the most delicate parts of the eye, many people state that the operation can be extremely risky.
Simply puts, a easy mistake could almost cause an person's life time blindness. Hence, it is necessary to think about many aspects before choosing whether LASIK eye surgery is the ideal corrective step one needs to go through.

LASIK eye surgery may fix your vision but it does not always indicate that it can give you a ideal vision. Even if analytical reports show that 70% of the patients might have 20/20 vision, this does not always suggest they have perfect vision as well.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgical treatment the method most individuals see it
On the other hand, the examination of the structural part of the eye might be made in several methods. It needs to be well remembered that a patient with an eye problem may have other problems. Frequently other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can alert the physician and the patient to troubles in some disturbances of other parts of the official statement body even prior to other signs provide themselves.
Like its tangible counterpart, LASIK eye surgical treatment is another kind of vision correction.
