The eye can be examined with relative ease as to both its function and its structure. A practical examination consists of the capability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be evaluated in numerous ways. The client may be asked to identify illuminated letter or things of differing sizes on what is known as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, particularly in glaucoma, the stress in the eyeball is increased considerably.
It should be well kept in mind that a client with an eye problem might have other problems. Often other physical conditions are main and affect the eye as a effect. The appearance of the eye can signal the physician and the patient to problems in some disturbances of other parts of the body even before other signs provide themselves.
As a result, one's reliance on sight is stressed when one faces a momentary or possible permanent loss of this important sense. Hence, when corrective steps are sought, particular kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are bothered with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were established to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery 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 distinction is that with this type of surgical treatment, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment is to create a threadlike, rounded "flap" in the cornea using 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.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgery, there are still disadvantages that individuals should know. Probably, the main factor why this type of eye surgery has become well accepted is due to the fact that the majority of its cases had been successful.
However, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most sensitive part of the eye
Since LASIK eye surgical treatment involves the operation of the retina, which is one of the most delicate parts of the eye, the majority of people state that the operation can be extremely dangerous.
In other words, a simple error could nearly trigger an person's lifetime loss of sight. It is essential to think about many elements before deciding whether LASIK eye surgical treatment is the right corrective procedure one has to go through.
2. It is not a best treatment
LASIK eye surgery may correct your vision however it does not necessarily mean that it can offer you a twenty-twenty. Even if analytical reports reveal that 70% of the clients may have 20/20 vision, this does not necessarily mean they have perfect vision.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgical treatment the way a lot of people view it
On the other hand, the evaluation of the structural part of the eye might be made in several ways. It needs to be well kept in mind that a patient with an eye issue might have other problems. Often other physical conditions are primary and affect the eye as a consequence. The look of the eye can notify the he has a good point doctor and the client to troubles in some disturbances of other parts of the body even prior to other symptoms present themselves.
Like its tangible equivalent, LASIK eye surgery is another form of vision correction.
