The eye can be examined with relative ease regarding both its function and its structure. A practical examination includes the capability to move in the orbit and the response of the pupil 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 differing sizes on exactly what is called the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in several ways. Stress within the eyeball is determined by a "tonometer." In particular diseases, particularly in glaucoma, the tension in the eyeball is increased significantly.
Nevertheless, it must be well kept in mind that a patient with an eye issue may have other problems as well. Frequently other physical conditions are main and affect the eye as a consequence. The look of the eye can signal the client and the physician to troubles in some disturbances of other parts of the body even before other symptoms provide themselves.
As a result, one's reliance on sight is emphasized when one faces a possible or short-lived permanent loss of this important sense. When corrective steps are looked for, certain types of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are troubled with the fact that they have 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. Among 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 tangible counterpart, LASIK eye surgical treatment is another kind of vision correction. The only distinction is that with this kind of surgery, one's vision is corrected permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely transformed. This can be done using an "excimer laser."
The primary function of this surgery is to develop 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, allowing 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 should understand. Probably, the main reason this kind of eye surgical treatment has become well accepted is because the majority of its cases had succeeded.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation used 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 parts of the eye, many people state that the operation can be very dangerous.
Simply puts, a basic error could nearly trigger an person's life time blindness. It is important to consider numerous elements prior to deciding whether LASIK eye surgery is the best corrective procedure one has to undergo.
2. It is not a ideal treatment
LASIK eye surgical treatment may fix your vision but it does not always suggest that it can give you a ideal vision. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not always suggest they have perfect vision.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the perfect eye surgical treatment the method a lot of people view it
On the other hand, the assessment of the structural part of the eye might be made in several ways. It should be well remembered that a client with an eye issue may have other issues. Typically other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can notify the client and the physician to difficulties in some disruptions of other parts additional info of the body even prior to other symptoms present themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
