The eye can be taken a look at with relative ease as to both its function and its structure. A functional evaluation includes the ability to relocate the orbit and the reaction of the pupil to light and lodging.
The function of the eye may be checked in a number of ways. The patient might be asked to recognize illuminated letter or objects of differing sizes on what is known as the Snellen chart.
Conversely, the assessment 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, specifically in glaucoma, the tension in the eyeball is increased markedly.
It needs to be well remembered that a patient with an eye problem may have other issues. Frequently other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can alert the physician and the client to troubles in some disruptions of other parts of the body even before other symptoms present themselves.
One's dependence on sight is stressed when one deals with a possible or temporary long-term loss of this essential sense. When corrective measures are sought, certain kinds of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some people are bothered with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to encourage reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Generally, LASIK eye surgical treatment is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its tangible equivalent, LASIK eye surgery is another kind of vision correction. The only difference is that with this type of surgery, one's vision is fixed completely.
With LASIK eye surgery, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The primary purpose of this surgical treatment 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 lastly reformed, enabling better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgery, there are still disadvantages that people need to know. Most likely, the main factor why this type of eye surgery has become well accepted is due to the fact that the majority of its cases had achieved success.
However, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to try these out the most delicate part of the eye
Due to the fact that LASIK eye surgery involves the operation of the retina, which is one of the most delicate parts of the eye, many people say that the operation can be really dangerous.
To puts it simply, a basic mistake could almost cause an individual's life time loss of sight. Thus, it is essential to think about lots of aspects before choosing whether LASIK eye surgical treatment is the best corrective procedure one needs to undergo.
2. It is not a ideal treatment
LASIK eye surgery may correct your vision but it does not always indicate that it can provide you a ideal vision. Even if statistical reports reveal that 70% of the patients might have 20/20 vision, this does not necessarily suggest they have ideal vision.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the perfect eye surgery the method the majority of people view it
Alternatively, the examination of the structural part of the eye may be made in a number of methods. It should be well remembered that a patient with an eye issue might have other issues. Frequently other physical conditions are primary and impact the eye as a consequence. The look of the eye can notify the client and the physician to problems in some disruptions of other parts of the body even prior to other signs provide themselves.
Like its concrete equivalent, LASIK eye surgical treatment is another type of vision correction.
