The eye can be examined with relative ease regarding both its function and its structure. A functional examination includes the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye may be tested in several methods. The client may be asked to determine illuminated letter or objects of differing sizes on what is called the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in numerous methods. Stress within the eyeball is determined by a "tonometer." In particular illness, especially in glaucoma, the stress in the eyeball is increased markedly.
It ought to be well remembered that a client with an eye problem might have other problems. Often other physical conditions are primary and impact the eye as a repercussion. The look of the eye can signal the doctor and the client to difficulties in some disruptions of other parts of the body even prior to other signs provide themselves.
One's dependence on sight is emphasized when one faces a possible or short-lived permanent loss of this important sense. For this reason, when restorative measures are sought, specific forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgery is another kind of vision correction. The only distinction is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
The main function of this surgery is to create a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people must know. Probably, the main factor why this kind of eye surgery has ended up being well accepted is since the majority of its cases had achieved success.
However, in spite of its success, there are still some downsides. Here is the list:

Because LASIK eye surgery involves the operation of the retina, which is among the most sensitive parts of the eye, the majority of people say that the operation can be really risky.
In other words, a basic error might nearly trigger an individual's lifetime loss of sight. It is important to think about lots of factors prior to choosing whether LASIK eye surgery is the ideal restorative step one has to undergo.
2. It is not a ideal treatment
LASIK eye surgical treatment may fix your vision but it does not necessarily imply that it can offer you a best vision. Even if statistical reports reveal that 70% of the patients might view it now have 20/20 vision, this does not necessarily mean they have perfect vision as well.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the perfect eye surgery the method the majority of people view it
On the other hand, the assessment of the structural part of the eye might be made in several ways. It should be well remembered that a patient with an eye issue might have other problems. Frequently other physical conditions are main and impact the eye as a consequence. The appearance of the eye can signal the patient and the physician to troubles in some disturbances of other parts of the body even prior to other symptoms provide themselves.
Like its tangible counterpart, LASIK eye surgical treatment is another kind of vision correction.
