The eye can be examined with relative ease as to both its function and its structure. A practical examination includes the ability to move in the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be evaluated in a number of methods. The patient may be asked to determine illuminated letter or items of differing sizes on what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye may be made in a number of methods. Tension within the eyeball is determined by a "tonometer." In particular illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
However, it must be well kept in mind that a patient with an eye issue might have other issues also. Frequently other physical conditions are main and affect the eye as a repercussion. The look of the eye can notify the physician and the patient to difficulties in some disruptions of other parts of the body even prior to other signs present themselves.
Subsequently, one's dependence on sight is emphasized when one deals with a possible or short-term permanent loss of this crucial sense. When corrective measures are sought, particular forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate decreased utilization of contact lenses or glasses. One of 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 concrete equivalent, LASIK eye surgery is another type of vision correction. The only distinction is that with this kind of surgical treatment, one's vision is remedied permanently.
With LASIK eye surgery, the refractive mistakes in the cornea are completely changed. This can be done utilizing 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, 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 reason that this type of eye surgery has actually become well accepted is because the majority of its cases had achieved success.
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
Because LASIK eye surgical treatment includes the operation of the retina, which is one of the most sensitive portions of the eye, the majority of people state that the operation can be extremely dangerous.
To puts it simply, a easy mistake could nearly cause an individual's life time loss of sight. Thus, it is important to think about many aspects before deciding whether LASIK eye surgery is the right corrective measure one has to go through.
2. It is not a perfect procedure
LASIK eye surgery may fix your vision however it does not always mean that it can provide you a ideal vision. Even if analytical reports reveal that 70% of the clients may have 20/20 vision, this does not always imply they have ideal vision.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not constantly be the perfect eye surgery the way the majority of people view it
Alternatively, the assessment of the structural part of the eye might be made in several ways. It should be well kept in mind that a patient with an eye problem might have other problems. Frequently other physical conditions are primary and affect the eye as a effect. The appearance of the eye can inform the physician and the patient to difficulties in some disruptions of other parts of the see page body even before other signs provide themselves.
Like its concrete counterpart, LASIK eye surgery is another kind of vision correction.
