The eye can be analyzed with relative ease regarding both its function and its structure. A practical evaluation includes the capability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye may be evaluated in several ways. The patient may be asked to determine illuminated letter or objects of varying sizes on exactly what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye may be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In certain diseases, specifically in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it needs to be well kept in mind that a patient with an eye problem may have other problems also. Typically other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can inform the physician and the client to troubles in some disruptions of other parts of the body even before other signs provide themselves.
As a result, one's reliance on sight is highlighted when one deals with a possible or momentary permanent loss of this vital sense. When corrective procedures are looked for, specific types of vision correction such as contact lenses or glasses are recommended.
On the other hand, some individuals are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another type of vision correction. The only difference is that with this type of surgery, one's vision is remedied permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The check that 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 much 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 need to understand. Most likely, the primary reason that this kind of eye surgical treatment has actually become well accepted is because the majority of its cases had succeeded.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Since LASIK eye surgical treatment 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 extremely dangerous.
To puts it simply, a simple error could almost cause an person's lifetime loss of sight. For this reason, it is very important to think about numerous factors before choosing whether LASIK eye surgery is the best corrective procedure one has to go through.
2. It is not a perfect procedure
LASIK eye surgery might correct your vision but it does not necessarily imply that it can offer you a perfect vision. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not always imply they have perfect vision as well.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the ideal eye surgery the method many people view it
Alternatively, the evaluation of the structural part of the eye may be made in several ways. It should be well remembered that a patient with an eye issue may have other problems. Often other physical conditions are main and impact the eye as a effect. The look of the eye can signal the client and the doctor to troubles in some disruptions of other parts of the body even prior to other signs provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another kind of vision correction.
