The eye can be analyzed with relative ease as to both its function and its structure. A functional examination includes 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 client may be asked to identify illuminated letter or objects of differing sizes on what is referred to as the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several methods. Tension within the eyeball is determined by a "tonometer." In particular illness, particularly in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it should be well remembered that a patient with an eye problem might have other problems too. Often other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can notify the physician and the patient to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.
Subsequently, one's reliance on sight is emphasized when one deals with a possible or short-term irreversible loss of this vital sense. When restorative procedures are looked for, specific types of vision correction such as contact lenses or eyeglasses are prescribed.
On the other hand, some people are troubled with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate decreased utilization of contact lenses or glasses. Among 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 like it another type of vision correction. The only difference is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
The main purpose of this surgical treatment is to produce a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to know. Most likely, the main reason this kind of eye surgery has actually become well accepted is due to the fact that most of its cases had actually achieved success.
However, 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 surgery involves the operation of the retina, which is one of the most sensitive portions of the eye, many people say that the operation can be extremely risky.
Simply puts, a basic mistake might almost cause an individual's life time blindness. Thus, it is very important to think about many elements before deciding whether LASIK eye surgical treatment is the best restorative step one has to go through.
2. It is not a best procedure
LASIK eye surgery might fix your vision but it does not always suggest that it can provide you a twenty-twenty. Even if statistical reports reveal that 70% of the patients might have 20/20 vision, this does not necessarily mean they have perfect vision as well.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgery the method the majority of people view it
Alternatively, the evaluation of the structural part of the eye might be made in a number of methods. It ought to be well kept in mind that a patient with an eye issue may have other problems. Typically other physical conditions are primary and impact the eye as a effect. The appearance of the eye can inform the doctor and the patient to troubles in some disturbances of other parts of the body even before other signs present themselves.
Like its tangible equivalent, LASIK eye surgery is another type of vision correction.
