The eye can be analyzed with relative ease regarding both its function and its structure. A practical examination includes the ability to move in the orbit and the response of the student to light and accommodation.
The function of the eye might be checked in several ways. The patient may be asked to determine illuminated letter or things of differing sizes on exactly what is known as the Snellen chart.
Conversely, the evaluation 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 specific illness, specifically in glaucoma, the stress in the eyeball is increased markedly.
However, it should be well bore in mind that a patient with an eye problem may have other issues too. Often other physical conditions are primary and affect the eye as a consequence. The look of the eye can signal the client and the doctor to difficulties in some disruptions of other parts of the body even before other signs present themselves.
One's dependence on sight is emphasized when one deals with a possible or short-term permanent loss of this essential sense. For this reason, when corrective measures are looked for, specific forms of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some individuals are bothered with the reality that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgeries were established to motivate 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 counterpart, LASIK eye surgical treatment is another kind of vision correction. The only distinction is that with this kind of surgical treatment, one's vision is remedied completely.
With LASIK eye surgery, the refractive errors in the cornea are completely transformed. This can be done using an "excimer laser."
The main function of this surgery is to create a threadlike, rounded "flap" in the cornea using a blade called "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, allowing much better the eye to direct more light into the retina.
Popularity vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that people need to know. Probably, the primary my link reason this type of eye surgical treatment has actually become well accepted is since the majority of its cases had been successful.
In spite of its success, there are still some disadvantages. 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 among the most sensitive portions of the eye, the majority of individuals say that the operation can be extremely dangerous.
In other words, a simple mistake might almost cause an individual's lifetime blindness. It is essential to think about numerous elements prior to choosing whether LASIK eye surgical treatment is the best restorative procedure one has to go through.
2. It is not a ideal treatment
LASIK eye surgical treatment might fix your vision but it does not necessarily imply that it can give you a perfect vision. Even if statistical reports show that 70% of the clients might have 20/20 vision, this does not always indicate they have ideal vision also.
Given all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not constantly be the perfect eye surgery the way the majority of people see it
Alternatively, the assessment of the structural part of the eye might be made in several methods. It ought to be well remembered that a patient with an eye problem may have other problems. Typically other physical conditions are primary and affect the eye as a repercussion. The look of the eye can inform the patient and the physician to troubles in some disruptions of other parts of the body even before other signs provide themselves.
Like its tangible equivalent, LASIK eye surgery is another form of vision correction.
