The eye can be taken a look at 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 reaction of the pupil to light and lodging.
The function of the eye might be evaluated in several ways. The patient might be asked to recognize illuminated letter or things of differing sizes on what is called the Snellen chart.
Conversely, the examination of the structural part of the eye may be made in a number of methods. Stress within the eyeball is determined by a "tonometer." In certain diseases, particularly in glaucoma, the stress in the eyeball is increased considerably.
It should be well remembered that a patient with an eye problem might have other problems. Often other physical conditions are primary and affect the eye as a effect. The look of the eye can inform the client and the physician to difficulties in some disruptions of other parts of the body even prior to other signs present themselves.
One's reliance on sight is highlighted when one deals with a momentary or possible irreversible loss of this important sense. Thus, when corrective procedures are looked for, particular types of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some individuals are troubled with that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were developed to encourage decreased usage of contact lenses or glasses. One of 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 equivalent, LASIK eye surgery is another form of vision correction. The only difference is that with this type of surgery, one's vision is corrected completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The main function of this surgery is to develop 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, permitting better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to know. Most likely, the main reason that this type of eye surgical treatment has become well accepted is due to the fact that the majority 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 applied to the most sensitive part of the eye
Because LASIK eye surgical treatment involves the operation of the retina, which is one of the most delicate portions of the eye, a lot of people state that the operation can be very dangerous.
In other words, a simple error might practically trigger an individual's lifetime loss of sight. Hence, it is essential to consider lots of factors prior to deciding whether LASIK eye surgical treatment is the best restorative measure one needs to undergo.
2. It is not a best treatment
LASIK eye surgery might fix your vision however it does not necessarily indicate that it can offer you a twenty-twenty. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not always mean they have ideal vision as well.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not always be the ideal eye surgical treatment the way many people see it
Conversely, the examination of the structural part of the eye might be made in a number of ways. It should be well kept use this link in mind that a client with an eye problem may have other problems. Frequently other physical conditions are primary and impact the eye as a effect. The appearance of the eye can alert the patient and the doctor to troubles in some disruptions of other parts of the body even before other signs present themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another type of vision correction.
