The eye can be taken a look at with relative ease regarding both its function and its structure. A practical assessment consists of the ability to move in the orbit and the response of the pupil to light and accommodation.
The function of the eye might be evaluated in a number of ways. The client might be asked to determine illuminated letter or objects of differing sizes on what is known as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in several ways. Stress within the eyeball is determined by a "tonometer." In certain illness, particularly in glaucoma, the stress in the eyeball is increased significantly.
However, it needs to be well kept in mind that a client with an eye problem might have other issues also. Typically other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can signal the patient and the doctor to problems in some disruptions of other parts of the body even before other symptoms provide themselves.
One's reliance on sight is stressed when one faces a momentary or possible irreversible loss of this essential sense. When corrective steps are sought, certain forms of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some individuals are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction. The only difference is that with this kind of surgery, one's vision is corrected completely.
With LASIK eye surgery, the refractive mistakes in the cornea are permanently changed. This can be done using an "excimer laser."
The main function 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 appeal of LASIK eye surgery, there are still disadvantages that individuals must know. Probably, the main factor why this kind of eye surgery has become well accepted is since many of its cases had actually achieved success.
Nevertheless, 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 surgery involves the operation of the retina, my latest blog post which is one of the most sensitive portions of the eye, most individuals state that the operation can be extremely risky.
Simply puts, a easy error could practically trigger an individual's lifetime blindness. It is important to think about numerous aspects prior to choosing whether LASIK eye surgery is the right restorative step one has to go through.
2. It is not a ideal treatment
LASIK eye surgical treatment might correct your vision but it does not always suggest that it can offer you a ideal vision. Even if analytical reports show that 70% of the clients may have 20/20 vision, this does not always indicate 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 ideal eye surgical treatment the way most people see it
Alternatively, the evaluation of the structural part of the eye might be made in several methods. It should be well kept in mind that a patient with an eye problem may have other issues. Frequently other physical conditions are main and affect the eye as a repercussion. The look of the eye can notify the client and the physician to difficulties in some disturbances of other parts of the body even prior to other signs provide themselves.
Like its tangible counterpart, LASIK eye surgery is another kind of vision correction.
