The eye can be analyzed with relative ease regarding both its function and its structure. A functional examination includes the ability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye might be evaluated in several methods. The patient may be asked to recognize illuminated letter or objects of varying sizes on what is understood as the Snellen chart.
Alternatively, the examination of the structural part of the eye may be made in a number of methods. Stress within the eyeball is determined by a "tonometer." In specific diseases, particularly in glaucoma, the tension in the eyeball is increased markedly.
It must be well kept in mind that a patient with an eye problem might have other problems. Frequently other physical conditions are primary and impact the eye as a consequence. The look of the eye can alert the physician and the patient to difficulties in some disturbances of other parts of the body even before other signs present themselves.
As a result, one's reliance on sight is highlighted when one faces a short-lived or possible irreversible loss of this crucial sense. When restorative steps are looked for, particular kinds of vision correction such as contact lenses or spectacles are recommended.
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 reason, advanced surgeries were established to motivate decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Basically, 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 distinction is that with this type of surgical treatment, one's vision is corrected permanently.
With LASIK eye surgery, the refractive mistakes in the cornea are completely changed. This can be done using an "excimer laser."
The primary function of this surgical treatment is to create this contact form 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.
Popularity vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people need to know. Most likely, the primary factor why this kind of eye surgery has become well accepted is due to the fact that most of its cases had been successful.
In spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Due to the fact that LASIK eye surgical treatment includes the operation of the retina, which is one of the most delicate parts of the eye, many individuals state that the operation can be extremely dangerous.
In other words, a basic mistake might almost cause an person's life time loss of sight. Hence, it is very important to think about lots of factors before deciding whether LASIK eye surgical treatment is the best restorative procedure one needs to go through.
2. It is not a best treatment
LASIK eye surgical treatment might correct your vision however it does not always suggest that it can give you a twenty-twenty. Even if statistical reports show that 70% of the patients might have 20/20 vision, this does not always imply 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 constantly be the ideal eye surgical treatment the way the majority of people view it
Conversely, the examination of the structural part of the eye may be made in numerous ways. It should be well kept in mind that a client with an eye problem might have other issues. Often other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can signal the client and the physician to problems in some disruptions of other parts of the body even prior to other symptoms present themselves.
