The eye can be analyzed with relative ease regarding both its function and its structure. A practical examination consists of the ability to relocate the orbit and the response of the pupil to light and accommodation.
The function of the eye might be evaluated in a number of ways. The patient may be asked to recognize illuminated letter or items of differing sizes on what is referred to as the Snellen chart.
Alternatively, the evaluation of the structural part of the eye might be made in a number of methods. Tension within the eyeball is measured by a "tonometer." In specific illness, particularly in glaucoma, the tension in the eyeball is increased considerably.
Nevertheless, it needs to be well kept in mind that a client with an eye problem might have other issues as well. Often other physical conditions are primary and impact the eye as a consequence. The look of the eye can notify the patient and the doctor to difficulties in some disruptions of other parts of the body even prior to other symptoms provide themselves.
One's dependence on sight is highlighted when one deals with a temporary or possible long-term loss of this crucial sense. For this reason, when corrective procedures are looked for, specific kinds of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are troubled 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 motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this kind of surgical treatment, one's vision is corrected completely.
With LASIK eye surgery, the refractive errors in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
The main purpose of this surgical treatment is to create a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing better the eye to direct more the original source light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that individuals must know. Most likely, the primary reason that this type of eye surgery has become well accepted is because the majority of its cases had achieved success.
Nevertheless, in spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied 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 sensitive parts of the eye, the majority of people state that the operation can be really risky.
Simply puts, a basic error might nearly cause an individual's life time blindness. Thus, it is crucial to think about many elements before choosing whether LASIK eye surgical treatment is the ideal restorative procedure one needs to go through.
2. It is not a best treatment
LASIK eye surgical treatment might remedy your vision but it does not necessarily imply that it can provide you a best vision. Even if statistical reports show that 70% of the clients may have 20/20 vision, this does not necessarily imply they have ideal vision.
Offered 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 most people view it
Conversely, the assessment of the structural part of the eye might be made in numerous ways. It must be well kept in mind that a client with an eye problem might have other problems. Often other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can inform the client and the doctor to troubles in some disturbances of other parts of the body even prior to other signs present themselves.
Like its tangible counterpart, LASIK eye surgery is another kind of vision correction.
