The eye can be examined with relative ease regarding both its function and its structure. A functional evaluation consists of the capability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye might be tested in a number of ways. The patient may be asked to identify illuminated letter or items of differing sizes on exactly what is called 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 specific diseases, especially in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it needs to be well kept in mind that a client with an eye problem may have other problems also. Typically other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can alert the physician and the patient to problems in some disturbances of other parts of the body even prior to other signs present themselves.
One's dependence on sight is highlighted when one deals with a momentary or possible permanent loss of this vital sense. When restorative procedures are looked for, particular types of vision correction such as contact lenses or glasses are prescribed.
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 factor, advanced surgical operations were developed to encourage decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another form 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 completely transformed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment is to create a threadlike, rounded "flap" in the cornea utilizing a blade known as "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.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that people find this need to understand. Probably, the main factor why this type of eye surgery has actually ended up being well accepted is because most of its cases had actually succeeded.
In spite of its success, there are still some disadvantages. 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 delicate portions of the eye, a lot of people say that the operation can be really dangerous.
In other words, a basic mistake could nearly trigger an person's life time blindness. It is essential to consider lots of elements before choosing whether LASIK eye surgical treatment is the ideal restorative step one has to undergo.
2. It is not a ideal procedure
LASIK eye surgery might fix your vision but it does not necessarily indicate that it can provide you a ideal vision. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not always imply 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 many people see it
Alternatively, the assessment of the structural part of the eye might be made in a number of ways. It ought to be well remembered that a client with an eye issue might have other issues. Often other physical conditions are primary and impact the eye as a effect. The appearance of the eye can signal the physician and the client to troubles in some disruptions of other parts of the body even before other signs provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction.
