The eye can be taken a look at with relative ease as to both its function and its structure. A functional assessment includes the capability to move in the orbit and the response of the pupil to light and lodging.
The function of the eye may be tested in a number of ways. The client may be asked to determine illuminated letter or objects of differing sizes on what is referred to as the Snellen chart.
Conversely, the assessment of the structural part of the eye may be made in a number of methods. Tension within the eyeball is determined by a "tonometer." In certain diseases, especially in glaucoma, the tension in the eyeball is increased markedly.
However, it needs to be well bore in mind that a client with an eye problem may have other issues as well. Often other physical conditions are primary and impact the eye as a consequence. The appearance of the eye can signal the patient and the physician to difficulties in some disturbances of other parts of the body even before other symptoms present themselves.
Subsequently, one's dependence on sight is emphasized when one faces a possible or short-lived permanent loss of this important sense. When restorative procedures are looked for, particular kinds of vision correction such as contact lenses or spectacles are recommended.
On the other hand, some people are bothered with the reality that they have actually some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgical operations were established to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgery.
Basically, LASIK eye surgery 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 surgical treatment, the refractive errors in the cornea are completely changed. This can be done utilizing an "excimer laser."
The primary purpose of this surgical treatment is to produce a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, allowing better the eye to direct more light into the retina.
Popularity vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgical treatment, there are still disadvantages that people must know. Probably, the primary reason that this type of eye surgical treatment has actually ended up being well accepted is due to the fact that most of its cases had been successful.
Nevertheless, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Since LASIK eye surgery includes the operation of the retina, which is one of the most sensitive portions of the eye, the majority of people say that the operation can be very risky.
In other words, a simple mistake could practically cause an individual's life time loss of sight. Hence, it is necessary to consider lots of aspects before deciding whether LASIK eye surgical treatment is the ideal corrective measure one needs to go through.
2. It is not a ideal procedure
LASIK eye surgery may correct your vision but it does not necessarily suggest that it can offer you a twenty-twenty. Even if analytical reports show that 70% of the patients may have 20/20 vision, this does not necessarily imply they have perfect vision also.
Provided all these things, it can be deduced that, in spite of the appeal of the operation, LASIK may not always be the ideal eye surgery the way many people see it
On the other hand, the evaluation of the structural part of the eye may be made in numerous methods. It needs to be well kept in mind that a client with an eye issue may have other issues. Typically other physical conditions are informative post primary and impact the eye as a repercussion. The appearance of the eye can alert the patient and the doctor to problems in some disturbances of other parts of the body even before other signs provide themselves.
Like its tangible equivalent, LASIK eye surgery is another type of vision correction.
