The eye can be analyzed with relative ease as to both its function and its structure. A functional assessment consists of the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be checked in a number of methods. The patient may be asked to determine illuminated letter or objects of differing sizes on what is understood as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several methods. Stress within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased significantly.
It needs to be well remembered that a client with an eye issue might have other problems. Often other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can alert the client and the doctor to troubles in some disturbances of other parts of the body even before other signs provide themselves.
Consequently, one's dependence on sight is highlighted when one deals with a possible or momentary irreversible loss of this vital sense. When restorative steps are looked for, specific types of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are bothered with the fact that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to motivate reduced usage 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 concrete equivalent, LASIK eye surgery is another form of vision correction. The only difference is that with this kind of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely changed. This can be done using an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade understood as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing 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 individuals should know. Most likely, the main reason this type of eye surgical treatment has ended up being well accepted is since many of its cases had succeeded.
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
Due to the fact that LASIK eye surgery includes the operation of the retina, which is among the most sensitive portions of the eye, the majority of people state that the operation can be very dangerous.
In other words, a easy mistake could nearly cause an individual's life time loss of sight. Thus, it is essential to consider numerous aspects prior to deciding whether LASIK eye surgical treatment is the ideal corrective step one needs to go through.
2. It is not a perfect procedure
LASIK eye surgery may fix your vision however it does not always suggest that it can offer you a best vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily mean they have perfect vision as well.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the ideal eye surgery the way many people view it
Conversely, the examination of the structural part of the eye may be made in several methods. It should be well kept in mind that read this a patient with an eye issue might have other issues. Frequently other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can alert the doctor and the client to problems in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
