The eye can be analyzed with relative ease regarding both its function and its structure. A practical assessment consists of the ability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye might be tested in several ways. The patient may be asked to determine illuminated letter or items of varying sizes on exactly what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
It should be well kept in mind that a patient with an eye problem might have other problems. Frequently other physical conditions are main and impact the eye as a consequence. The look of the eye can inform the patient and the physician to troubles in some disturbances of other parts of the body even before other signs provide themselves.
One's dependence on sight is stressed when one deals with a possible or short-lived permanent loss of this essential sense. Thus, when restorative steps are looked for, specific kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are bothered with the truth that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgery, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently transformed. This can be done using an "excimer laser."
The primary function of this surgery is to create a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series of unfolding useful reference 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 appeal of LASIK eye surgical treatment, there are still disadvantages that people need to know. Probably, the main reason this kind of eye surgery has actually ended up being well accepted is since the majority of its cases had actually been successful.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Because LASIK eye surgical treatment involves the operation of the retina, which is among the most sensitive portions of the eye, many people state that the operation can be extremely risky.
To puts it simply, a basic mistake could almost cause an individual's life time blindness. For this reason, it is necessary to think about many aspects before choosing whether LASIK eye surgical treatment is the best corrective step one has to undergo.
2. It is not a perfect treatment
LASIK eye surgery may correct your vision but it does not always imply that it can provide you a twenty-twenty. Even if statistical reports show that 70% of the clients might have 20/20 vision, this does not always imply they have perfect vision as well.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the perfect eye surgical treatment the method many people see it
On the other hand, the assessment of the structural part of the eye might be made in several methods. It should be well kept in mind that a patient with an eye problem may have other problems. Typically other physical conditions are primary and impact the eye as a repercussion. The look of the eye can signal the client and the physician to problems in some disturbances of other parts of the body even prior to other symptoms present themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another kind of vision correction.
