The eye can be analyzed with relative ease as to both its function and its structure. A practical evaluation includes the ability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in a number of ways. The client might be asked to recognize illuminated letter or things of varying sizes on exactly what is known as the Snellen chart.
Conversely, the evaluation of the structural part of the eye might be made in several methods. Tension within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the stress in the eyeball is increased significantly.
It must be well kept in mind that a client with an eye issue may have other issues. Typically other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can inform the physician and the patient to difficulties in some disturbances of other parts of the body even before other symptoms provide themselves.
Consequently, one's dependence on sight is highlighted when one deals with a short-term or possible long-term loss of this important sense. When restorative measures are sought, particular forms of vision correction such as contact lenses or glasses 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 factor, advanced surgical operations were established to motivate reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, 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 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 completely changed. This can be done using an "excimer laser."
The main purpose of this surgery is to produce a threadlike, rounded "flap" in the cornea using a blade known as "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
In the middle of the growing popularity of LASIK eye surgery, there are still disadvantages that individuals need to understand. Probably, the main reason this type of eye surgical treatment has actually become well accepted is because the majority of its cases had been successful.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most delicate part of the eye
Since LASIK eye surgery includes the operation of the retina, which is one of the most delicate parts of the eye, a lot of people state that the operation can be very risky.
Simply puts, a basic error might almost cause an person's life time blindness. For this reason, it is necessary to think about numerous factors before choosing whether LASIK eye surgery is the right corrective procedure one needs to undergo.
2. It is not a perfect treatment
LASIK eye surgical treatment might correct your vision but it does not necessarily mean that it can give you a best vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not necessarily imply they have ideal vision.
Provided all these things, it can be deduced that, official source in spite of the popularity of the operation, LASIK might not constantly be the perfect eye surgery the method a lot of people view it
Alternatively, the evaluation of the structural part of the eye may be made in several methods. It must be well remembered that a patient with an eye problem may have other problems. Often other physical conditions are main and affect the eye as a consequence. The appearance of the eye can inform the patient and the doctor to problems in some disturbances of other parts of the body even before other signs present themselves.
Like its concrete equivalent, LASIK eye surgery is another kind of vision correction.
