The eye can be analyzed with relative ease regarding both its function and its structure. A functional examination consists of the capability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye may be tested in several methods. The client might be asked to determine illuminated letter or objects of differing sizes on what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in a number of methods. Stress within the eyeball is measured by a "tonometer." In certain diseases, specifically in glaucoma, the tension in the eyeball is increased considerably.
However, it must be well kept in mind that a patient with an eye problem might have other problems as well. Often other physical conditions are main and impact the eye as a repercussion. The look of the eye can notify the doctor and the client to troubles in some disruptions of other parts of the body even before other symptoms present themselves.
One's reliance on sight is stressed when one deals with a momentary or possible irreversible loss of this crucial sense. Thus, when corrective steps are sought, particular kinds of vision correction such as contact lenses or spectacles are prescribed.
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 encourage reduced utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgical treatment is another type of vision correction. The only distinction is that with this type of surgery, one's vision is corrected permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely changed. This can be done using an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade understood 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 popularity of LASIK eye surgical treatment, there are still disadvantages that people need to understand. Most likely, the primary reason that this type of eye surgical treatment has actually become well accepted is due to the fact that the majority of its cases had actually been successful.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Since LASIK eye surgical treatment involves the operation of the retina, which is among the most delicate parts of the eye, the majority of people state that the operation can be really risky.
In other words, a simple mistake could almost cause an individual's lifetime loss of sight. For this reason, it is very important to think about numerous aspects prior to choosing whether LASIK eye surgical treatment is the ideal restorative step one has to undergo.
2. It is not a perfect procedure
LASIK eye surgery may fix your vision but it does not necessarily suggest that it can offer you a perfect 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 also.
Offered all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not constantly be the perfect eye surgery the method many people view it
Conversely, the evaluation page of the structural part of the eye might be made in several methods. It ought to be well kept in mind that a client with an eye issue might have other problems. Typically other physical conditions are primary and impact the eye as a effect. The appearance of the eye can inform the patient and the physician to difficulties in some disruptions of other parts of the body even before other signs provide themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction.
