The eye can be examined with relative ease regarding both its function and its structure. A functional examination consists of the ability to relocate the orbit and the reaction of the student to light and accommodation.
The function of the eye might be evaluated in several ways. The client might be asked to determine illuminated letter or things of differing sizes on what is called the Snellen chart.
Alternatively, the evaluation of the structural part of the eye might be made in several methods. Tension within the eyeball is measured by a "tonometer." In particular diseases, specifically in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it should be well kept in mind that a patient with an eye issue may have other problems too. Frequently other physical conditions are main and affect the eye as a consequence. The look of the eye can notify the patient and the doctor to problems in some disruptions of other parts of the body even prior to other signs present themselves.
Consequently, one's reliance on sight is stressed when one faces a possible or temporary permanent loss of this crucial sense. Hence, when corrective measures are sought, specific kinds of vision correction such as contact lenses or glasses 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 surgical operations were established to encourage decreased utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another type of vision correction. The only distinction is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are completely transformed. 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 much 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 understand. Probably, the primary reason this kind of eye surgery has actually become well accepted is because 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 delicate part of the eye
Since LASIK from this source eye surgical treatment includes the operation of the retina, which is one of the most delicate parts of the eye, many people state that the operation can be very dangerous.
Simply puts, a simple mistake could nearly trigger an individual's lifetime loss of sight. It is crucial to think about many elements prior to choosing whether LASIK eye surgical treatment is the right corrective step one has to go through.
2. It is not a best treatment
LASIK eye surgical treatment may correct your vision but it does not always suggest that it can give you a ideal vision. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not necessarily imply they have perfect vision.
Offered all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgery the method most individuals see it
On the other hand, the evaluation of the structural part of the eye might be made in several ways. It must be well kept in mind that a patient with an eye issue may have other problems. Typically other physical conditions are primary and affect the eye as a consequence. The look of the eye can signal the client and the physician to troubles in some disturbances of other parts of the body even before other signs present themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another type of vision correction.
