The eye can be taken a look at with relative ease as to both its function and its structure. A functional examination includes the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye may be checked in several methods. The patient may be asked to recognize illuminated letter or objects of varying sizes on exactly what is called the Snellen chart.
Alternatively, the examination of the structural part of the eye may be made in a number of ways. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased markedly.
It must be well kept in mind that a client with an eye problem might have other problems. Typically other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can notify the patient and the physician to troubles in some disruptions of other parts of the body even prior to other signs provide themselves.
Subsequently, one's reliance on sight is highlighted when one deals with a possible or short-term permanent loss of this important sense. For this reason, when corrective steps are looked for, particular forms of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some people are bothered with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were established to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this type of surgical treatment, one's vision is fixed 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 surgical treatment is to produce 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, helpful resources enabling 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 know. Most likely, the primary factor why this type of eye surgical treatment has ended up being well accepted is because the majority of its cases had actually been effective.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Due to the fact that LASIK eye surgery involves the operation of the find retina, which is one of the most sensitive parts of the eye, many people state that the operation can be extremely risky.
Simply puts, a easy error might nearly cause an person's life time loss of sight. For this reason, it is necessary to consider lots of factors before choosing whether LASIK eye surgery is the ideal restorative step one needs to undergo.
2. It is not a ideal treatment
LASIK eye surgery may fix your vision but it does not always indicate that it can offer you a perfect vision. Even if analytical reports reveal that 70% of the patients may have 20/20 vision, this does not necessarily suggest they have perfect vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not constantly be the ideal eye surgery the way most people see it
On the other hand, the examination of the structural part of the eye may be made in a number of methods. It must be well kept in mind that a client with an eye problem may have other problems. Typically other physical conditions are main and impact the eye as a repercussion. 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 symptoms present themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another form of vision correction.
