LASIK or laser in situ keratomileusis, is a form of corrective surgery that help patients who are suffering from nearsightedness (Myopia), farsightedness (Hypermetropia) and even astigmatism (cylindrical power in glasses). This procedure aims at correcting the shape of the cornea, which is the transparent layer that lines the front of the eye. Through this procedure, the cornea is reshaped so that the retina receives a focused light.
So what are the health tips for people going through a LASIK procedure? Here is our take:
The biggest advantage of LASIK is that it helps people to get rid of Glasses and contact lenses, which sometimes are cosmetically unacceptable and in some cases are visually disabling.
Best part of LASIK is that it is:
Minor side effects like dryness, glare and halos, if appear, subside with time.
Any person 18 yrs or older who fulfils the following criteria can undergo Lasik surgery
1. Stable refraction
2. Corneal thickness and topography should be in a normal range
3. Dilated retinal examination should be normal
4. Adequately wet eyes
Note: One should abstain from wearing contact lens at least 2 weeks before the procedure.
Precaution after the Procedure:
Patient is likely to have some inflammation after the procedure and temporary dryness.
Use medicines as prescribed by the doctor
1. Avoid any type of eye makeup for at least 1 month after surgery
2. Avoid swimming or water sports for at least 2- 3 weeks after surgery
Going through a LASIK procedure is a matter of finding the right specialist and ensuring that you take all the precautions before the procedure. Also, it is important to look into your medical history and eyes in particular so as to avoid complications
Now, this problem is being noticed to a great extent among children. On one hand, where the cost of eye exams on an annual basis along with new glasses can be a financial constraint for certain families, the long-term risks that are associated with myopia progression can be far greater.
Before going ahead to look at some of the steps which children must take, in order to prevent the occurrence of Myopia, let us see what are signs and symptoms which lead to Myopia:
Signs and Symptoms:
When any child is nearsighted, then he or she will face problems like:
Steps Which Children Must Take
There are certain steps, which should be followed by children and though would be helping in preventing the progression of myopia:
Some of the healthy habits include:
Even if a child gets screened for myopia in his or her school, it is still a good idea to take them for a check-up in case they complain of headaches, squint or blurred vision.
One thing which everyone must ensure is to always go ahead to show problems related to the eye, like myopia, to an eye doctor, who is better known as an Ophthalmologist rather than going for any Optician. An Optometrist is perfectly trained to provide eye as well as vision care. He or she is able to perform eye examinations like evaluating the eye muscle balance to detect problems related to double vision and hence prescribe corrective lenses to correct those problems.
One should also make their children undergo a retina examination, which allows an eye doctor to evaluate the back of their eyes, including the retina, the optic disc and the underlying layer of blood vessels, which provide nourishment to the retina. This is especially important in myopes who have higher incidence of vitreous jelly degeneration and predisposed to peripheral retinal degeneration and breaks which lead to retinal detachments and potential loss of vision.
Interventions to Reduce Rapid Progression of Myopia in Children
To some extent, Bifocal or progressive glasses or Soft Contact Lenses have also been proved to be effective in reducing the progression of myopia, hence they could be tried out by children, who are suffering from the same.
Myopia is also known by the name of nearsightedness. It is one of the most common refractive disorders of the eye. Over the years, it has become more prevalent. According to a recent study conducted by the National Eye Institute (NEI), myopia has grown more prevalent from 25 percent in 1972 to around 40% percent in 2004 in United States.
The exact cause of the prevalence of this disorder in USA is not known. However, many doctors are of the opinion that eye fatigue due to overuse of computers can be the primary reason behind the spread of this disorder. It could also be affected by genetical links.
Myopia Symptoms And Signs:
It is time to take care of your eyes if you have difficulty in reading the sign boards on road or seeing objects from a distance. This could be a sign for myopia if you are able to see things clearly from a closer distance. There are several symptoms of myopia, including strain on eyes, headaches and squinting. If these signs don’t vanish after wearing lenses or spectacles, you must visit your ophthalmologist.
What are the factors that cause Myopia or Nearsightedness?
It occurs at a time when the eyeball of the patient is too long. The lens of the patient will be too long as compared to the focusing power of the cornea or the eye lens. This condition leads to the focusing of light rays at a point in front of the retina. The rays don’t focus directly on the retina’s surface. Myopia can also be caused if the lens of the eye is too curved. Myopia can also be caused due to a combination of factors. The problem may start from childhood. You are also at the risk of developing the problem if your parents have had the problem.
Myopia is not a rare disorder of the eye. People living with myopia have several options of its treatment. It can be rectified or corrected with the help of spectacles and contact lenses. It can also be corrected by refractive surgery. The kind of treatment to be chosen depends upon the degree of your myopia. You will be asked to wear lenses or spectacles for a prescribed amount of time, depending upon the degree of your disorder.
In myopia there are Retinal changes like Retinal weakness (lattice degeneration) Retinal hole and break, which need laser treatment to prevent retinal detachment. It needs surgical correction. So, myopia patients need to undergo dilated pupil retinal examination yearly, as early changes mentioned above are asymptomatic.
If you are suffering from myopia, the doctor will prescribe you to wear spectacles or lenses of a certain power that will be preceded by a minus (-) sign.
