The eye can be examined with relative ease regarding both its function and its structure. A functional examination includes the capability to relocate the orbit and the reaction of the student to light and lodging.
The function of the eye may be tested in a number of ways. The patient may be asked to recognize illuminated letter or objects of varying sizes on exactly what is understood as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in several methods. Stress within the eyeball is determined by a "tonometer." In particular illness, especially in glaucoma, the stress in the eyeball is increased markedly.
However, it needs to be well remembered that a patient with an eye problem might have other problems as well. Frequently other physical conditions are primary and impact the eye as a consequence. The look of the eye can alert the patient and the physician to difficulties in some disruptions of other parts of the body even prior to other symptoms present themselves.
As a result, one's dependence on sight is highlighted when one faces a possible or momentary long-term loss of this essential sense. When restorative procedures are sought, certain kinds 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 utilization of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgical treatment is the short-term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another form of vision correction. The only distinction is that with this kind 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 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, enabling much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing popularity of LASIK eye surgery, there are still disadvantages that individuals need to understand. Probably, the primary factor why this type of eye surgery has actually ended up being well accepted is because 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 used to the most sensitive part of the eye
Because LASIK eye surgery includes the operation of the retina, which is among the most delicate parts of the eye, many people state that the operation can be really risky.
Simply puts, a simple mistake could almost trigger an person's life time blindness. It is important to think about lots of factors prior to deciding whether LASIK eye surgical treatment is the right restorative procedure one has to go through.
2. It is not a perfect treatment
LASIK eye surgical treatment may correct your vision but it does not visit site necessarily suggest that it can provide you a ideal see this site 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.
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 way the majority of people view it
On the other hand, the examination of the structural part of the eye may be made in a number of ways. It should be well kept in mind that a client with an eye problem might have other issues. Typically other physical conditions are primary and affect the eye as a repercussion. The look of the eye can notify the physician and the client to difficulties in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Like its concrete counterpart, LASIK eye surgical treatment is another type of vision correction.
