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 move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be evaluated in numerous methods. The client might be asked to recognize illuminated letter or objects of varying sizes on exactly what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye may be made in a number of ways. Tension within the eyeball is measured by a "tonometer." In particular diseases, especially in glaucoma, the stress in the eyeball is increased markedly.
Nevertheless, it must be well kept in mind that a patient with an eye issue may have other problems too. Frequently other physical conditions are main and impact the eye as a effect. The appearance of the eye can notify the patient and the physician to troubles in some disturbances of other parts of the body even prior to other symptoms provide themselves.
One's reliance on sight is emphasized when one faces a short-term or possible irreversible loss of this vital sense. Hence, when restorative procedures are looked for, specific kinds of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are troubled with the truth that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were developed to encourage decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgery.
Essentially, LASIK eye surgery is the brief term for "Laser-Assisted In Situ Keratomileusis." Like its concrete equivalent, LASIK eye surgery is another type of vision correction. The only distinction is that with this kind of surgery, one's vision is remedied permanently.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The primary function of this surgery is to develop a threadlike, rounded "flap" in the cornea utilizing a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing appeal of LASIK eye surgical treatment, there are still disadvantages that individuals should know. Probably, the primary reason this kind of eye surgery has become well accepted is because most of its cases had achieved success.
In spite of its success, there are still some downsides. Here is the list:
1. It is an operation used to the most delicate part of the eye
Because LASIK eye surgical treatment includes the operation of the retina, which is one of the most sensitive parts of the eye, most people say that the operation can be really risky.
In other words, a basic error might practically trigger an person's lifetime loss of sight. It is important to think about many factors before choosing whether LASIK eye surgery is the ideal corrective procedure one has to go through.
2. It is not a best procedure
LASIK eye surgery might fix your vision but it does not necessarily imply that it can offer you a perfect vision. Even if analytical reports show that other 70% of the clients might have 20/20 vision, this does not necessarily indicate they have perfect vision.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not constantly be the ideal eye surgical treatment the way many people view it
Alternatively, the assessment of the structural part of the eye may be made in several methods. It should be well remembered that a patient with an eye problem may have other issues. Often other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can signal the physician and the client to difficulties in some disturbances of other parts of the body even prior to other symptoms present themselves.
Like its tangible equivalent, LASIK eye surgery is another type of vision correction.
