The eye can be taken a look at with relative ease as to both its function and its structure. A functional evaluation consists of the capability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be checked in numerous ways. The patient may be asked to recognize illuminated letter or objects of varying sizes on what is referred to as the Snellen chart.
On the other hand, the assessment 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 particular 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 repercussion. The look of the eye can signal the patient and the physician to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.
Subsequently, one's dependence on sight is stressed when one faces a short-lived or possible long-term loss of this essential sense. When restorative measures are sought, certain types of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some individuals are troubled with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were developed to motivate reduced usage 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 click to read its tangible counterpart, LASIK eye surgery is another kind of vision correction. The only distinction is that with this type of surgical treatment, one's vision is remedied 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 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.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that individuals need to understand. Most likely, the main reason that this type of eye surgical treatment has become well accepted is since many of its cases had succeeded.
However, 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
Since LASIK eye surgical treatment involves the operation of the retina, which is among the most delicate portions of the eye, the majority of people state that the operation can be very risky.
In other words, a easy mistake might almost cause an individual's life time loss of sight. It is essential to think about lots of factors before deciding whether LASIK eye surgical treatment is the best corrective step one has to go through.
2. It is not a best treatment
LASIK eye surgery might fix your vision but it does not necessarily imply that it can provide you a best vision. Even if analytical reports reveal that 70% of the clients might have 20/20 vision, this does not necessarily indicate they have perfect vision also.
Provided all these things, it can be deduced that, in spite of the popularity of the operation, LASIK may not always be the ideal eye surgical treatment the way many people view it
Conversely, 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 patient with an eye problem may have other problems. Frequently other physical conditions are main and impact the eye as a effect. The look of the eye can notify the physician and the patient to difficulties in some disruptions of other parts of the body even before other symptoms provide themselves.
Like its tangible equivalent, LASIK eye surgical treatment is another form of vision correction.
