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 reaction of the pupil to light and accommodation.
The function of the eye may be evaluated in numerous methods. The patient may be asked to determine illuminated letter or objects of varying sizes on what is known as the Snellen chart.
On the other hand, the evaluation of the structural part of the eye may be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In specific diseases, particularly in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well kept in mind that a patient with an eye problem may have other issues as well. Typically other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can inform the doctor and the patient to problems in some disturbances of other parts of the body even before other symptoms present themselves.
As a result, one's dependence on sight is highlighted when one faces a temporary or possible permanent loss of this important sense. Hence, when corrective procedures are looked for, particular kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are troubled with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to motivate decreased utilization 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 concrete counterpart, LASIK eye surgical treatment is another kind of vision correction. The only difference is that with this type of surgery, 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 main purpose of this surgery is to create a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people should understand. Most likely, the primary factor why this kind of eye surgical treatment has ended up being well accepted is because over here many 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
Due to the fact that LASIK eye surgical treatment involves the operation of the retina, which is one of the most sensitive parts of the eye, the majority of individuals state that the operation can be really risky.
To puts it simply, a basic mistake might nearly trigger an individual's lifetime loss of sight. Thus, it is necessary to think about lots of elements prior to choosing whether LASIK eye surgical treatment is the right corrective measure one has to undergo.
2. It is not a best treatment
LASIK eye surgical treatment might remedy your vision however it does not always suggest that it can give you a perfect vision. Even if analytical reports reveal that 70% of the patients might have 20/20 vision, this does not necessarily indicate 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 perfect eye surgery the method the majority of people see it
On the other hand, the assessment of the structural part of the eye may be made in several methods. It must be well kept in mind that a patient with an eye issue might have other problems. Frequently other physical conditions are main and impact the eye as a consequence. The look of the eye can inform the client and the doctor to problems in some disruptions of other parts of the body even prior to other symptoms present themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another kind of vision correction.
