The eye can be examined with relative ease as to both its function and its structure. A functional assessment includes the ability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye might be tested in several ways. The patient might be asked to identify illuminated letter or things of varying sizes on what is called the Snellen chart.
Conversely, the evaluation of the structural part of the eye may be made in several methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased significantly.
Nevertheless, it needs to be well kept in mind that a client with an eye issue might have other problems too. Often other physical conditions are main and affect the eye as a repercussion. The appearance of the eye can inform the physician and the patient to difficulties in some disruptions of other parts of the body even prior to other signs provide themselves.
One's reliance on sight is emphasized when one deals with a possible or temporary long-term loss of this vital sense. When restorative procedures are looked for, particular forms of vision correction such as contact lenses or spectacles are prescribed.
On the other hand, some individuals are bothered with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate decreased usage of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
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 kind of surgical treatment, one's vision is fixed permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The main function of this surgical treatment is to produce a threadlike, rounded "flap" in the cornea using a blade called "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 surgical treatment, there are still disadvantages that individuals should know. Most likely, the main reason that this kind of eye surgical treatment has ended up being well accepted is due to the fact that most of its cases had actually achieved success.
In spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation used to the most delicate part of the eye
Because LASIK eye surgical treatment involves the operation of the retina, which is among the most sensitive portions of the eye, many people state that the operation can be extremely dangerous.
Simply puts, a easy error might practically trigger an individual's lifetime loss of sight. Hence, it is necessary to think about numerous aspects before choosing whether LASIK eye surgery is the best corrective measure one needs to undergo.
2. It is not a perfect treatment
LASIK eye surgery might fix your vision but it does not always mean that it can provide you a best vision. Even if analytical reports reveal that 70% of the patients might have 20/20 vision, this does not always home mean they have perfect vision as well.
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 the majority of people view it
Alternatively, the evaluation of the structural part of the eye may be made in numerous methods. It needs to be well kept in mind that a client with an eye problem may have other problems. Frequently other physical conditions are primary and affect the eye as a consequence. The look of the eye can notify the patient and the doctor to difficulties in some disturbances of other parts of the body even before other symptoms provide themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another kind of vision correction.
