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 student to light and accommodation.
The function of the eye may be tested in a number of methods. The patient may be asked to determine illuminated letter or items of varying sizes on what is referred to as the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in several methods. Stress within the eyeball is measured by a "tonometer." In certain diseases, especially in glaucoma, the stress in the eyeball is increased markedly.
However, it must be well remembered that a patient with an eye issue may have other problems too. Often 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 difficulties in some disruptions of other parts of the body even before other signs present themselves.
Consequently, one's reliance on sight is stressed when one faces a possible or temporary irreversible loss of this important sense. When corrective measures are sought, specific forms of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were established to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
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 distinction is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are permanently transformed. This can be done using an "excimer laser."
The main function of this surgical treatment is to develop a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series Bonuses of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people should know. Probably, the primary reason that this kind of eye surgical treatment has actually ended up being well accepted is due to the fact that the majority of its cases had actually been effective.
In spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most sensitive part of the eye
Because LASIK eye surgical treatment includes the operation of the retina, which is among the most sensitive parts of the eye, most individuals state that the operation can be very dangerous.
To puts it simply, a basic error might practically cause an individual's life time blindness. It is important to consider numerous aspects before choosing whether LASIK eye surgical treatment is the ideal corrective measure one has to go through.
2. It is not a best treatment
LASIK eye surgical treatment may correct your vision but it does not necessarily mean that it can give you a twenty-twenty. Even if statistical reports show that 70% of the clients might have 20/20 vision, this does not necessarily indicate they have perfect vision.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the ideal eye surgery the way most people see it
On the other hand, the examination of the structural part of the eye might be made in numerous methods. It should be well remembered that a patient with an eye problem might have other problems. Typically other physical conditions are main and impact the eye as a consequence. The appearance of the eye can inform the patient and the physician to troubles in some disruptions of other parts of the body even before other symptoms present themselves.
Like its concrete equivalent, LASIK eye surgery is another form of vision correction.
