The eye can be taken a look at with relative ease regarding both its function and its structure. A practical examination includes the capability to move in the orbit and the reaction of the student to light and accommodation.
The function of the eye may be tested in a number of ways. The patient might be asked to determine illuminated letter or items of varying sizes on what is known as the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in several ways. Stress within the eyeball is determined by a "tonometer." In particular diseases, especially in glaucoma, the tension in the eyeball is increased noticeably.
Nevertheless, it must be well bore in mind that a patient with an eye issue may have other issues also. Typically other physical conditions are primary and impact the eye as a effect. The look of the eye can notify the client and the doctor to problems in some disruptions of other parts of the body even before other symptoms present themselves.
As a result, one's reliance on sight is emphasized when one faces a momentary or possible permanent loss of this important sense. When corrective steps are sought, specific types of vision correction such as contact lenses or glasses are prescribed.
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 factor, advanced surgeries were developed to encourage decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Generally, LASIK eye surgical treatment 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 type of surgical treatment, one's vision is remedied permanently.
With LASIK eye surgery, the refractive mistakes in the cornea are completely transformed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment is to produce a threadlike, rounded "flap" in the cornea using a blade known as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling 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 must understand. Probably, the primary reason this type of eye surgery has ended up being well accepted is since many of its cases had succeeded.
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
Since LASIK eye surgery involves the operation of the retina, which is among the most delicate portions of the eye, most people state that the operation can be very risky.
To puts it simply, a simple error might almost cause an person's life time blindness. It is essential to think about many aspects prior to deciding whether LASIK eye surgery is the right corrective step one has to go through.
2. It is not a perfect treatment
LASIK eye surgery might correct your vision but it does not necessarily suggest that it can provide you a perfect vision. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this review does not always mean they have ideal vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the ideal eye surgery the way a lot 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 kept in mind that a patient with an eye issue may have other problems. Frequently other physical conditions are primary and affect the eye as a effect. The appearance of the eye can alert the patient and the doctor to troubles in some disturbances of other parts of the body even before other symptoms provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another form of vision correction.
