The eye can be taken a look at with relative ease regarding both its function and its structure. A functional evaluation includes the ability to move in the orbit and the response of the student to light and accommodation.
The function of the eye may be checked in numerous methods. The client may be asked to determine illuminated letter or objects of varying sizes on what is called the Snellen chart.
Conversely, the examination of the structural part of the eye might be made in several methods. Tension within the eyeball is measured by a "tonometer." In certain diseases, especially in glaucoma, the tension in the eyeball is increased considerably.
However, it ought to be well remembered that a client with an eye issue may have other issues also. Often other physical conditions are primary and impact the eye as a repercussion. The appearance of the eye can alert the doctor and the patient to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.
One's reliance on sight is highlighted when one deals with a possible or momentary permanent loss of this crucial sense. When restorative measures are sought, certain forms of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgery is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another kind of vision correction. The only difference is that with this kind of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently changed. This can be done using an "excimer laser."
The main purpose of this surgical treatment 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 look these up cornea is finally reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that individuals should know. Most likely, the main reason why this type of eye surgery has actually become well accepted is since the majority 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 applied to the most delicate part of the eye
Since LASIK eye surgical treatment involves the operation of the retina, which is among the most delicate portions of the eye, many people state that the operation can be very risky.
In other words, a easy mistake could nearly cause an individual's life time blindness. It is essential to think about lots of factors before deciding whether LASIK eye surgical treatment is the ideal corrective measure one has to undergo.
2. It is not a ideal treatment
LASIK eye surgical treatment might correct your vision but it does not necessarily imply that it can provide you a best vision. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not necessarily imply they have perfect vision too.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgical treatment the method the majority of individuals see it
Alternatively, the assessment of the structural part of the eye might be made in a number of methods. It must be well remembered that a patient with an eye problem may have other issues. Often other physical conditions are primary and impact the eye as a effect. The look of the eye can inform the patient and the physician to difficulties in some disturbances of other parts of the body even prior to other signs present themselves.
Like its concrete counterpart, LASIK eye surgery is another kind of vision correction.
