The eye can be examined with relative ease as to both its function and its structure. A functional assessment consists of the ability to move in the orbit and the response of the student to light and lodging.
The function of the eye might be tested in numerous methods. The client might be asked to recognize illuminated letter or objects of differing sizes on what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several methods. Tension within the eyeball is determined by a "tonometer." In specific illness, particularly in glaucoma, the tension in the eyeball is increased considerably.
It needs to be well kept in mind that a patient with an eye problem may have other problems. Typically other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can inform the doctor and the patient to troubles in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Subsequently, one's reliance on sight is highlighted when one faces a momentary or possible permanent loss of this vital sense. For this reason, when corrective steps are looked for, certain types of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to encourage decreased usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another form of vision correction. The only distinction 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 function of this surgery is to create 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, allowing better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgery, there are still disadvantages that people must know. Probably, the main factor why this kind of eye surgery has actually become well accepted is since most of its cases had actually succeeded.
In spite of its success, there are still some drawbacks. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Since LASIK eye surgery includes the operation of the retina, which is among the most sensitive parts of the eye, the majority of people state that the operation can be very risky.
Simply puts, a simple mistake could nearly cause an person's lifetime loss of sight. It is crucial to consider numerous elements prior to choosing whether LASIK eye surgery is the best corrective step one has to go through.
2. It is not a best procedure
LASIK eye surgery may correct your vision but it does not necessarily suggest that it can provide you a ideal vision. Even if statistical reports show that 70% of the patients might have 20/20 vision, this does not necessarily indicate they have perfect vision also.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the ideal eye surgical treatment the method many people see it
Conversely, the evaluation of the structural part of the eye may be made in several ways. It should be well remembered that a patient with an eye problem may have other issues. Typically other physical conditions are main and impact the eye as a repercussion. The appearance of the eye can alert the doctor and the patient to difficulties in some disruptions of other parts of the body even prior to other symptoms present themselves.
Like its tangible you could look here equivalent, LASIK eye surgery is another form of vision correction.
