Are you someone who is nearsighted or farsighted, have you ever felt the frustration or inconveniency in having to wear glasses or contact lenses? Try LASIK or Laser-Assisted in Situ Keratomileusis! LASIK is a surgical procedure that can reduce a person?s dependency on glasses or contact lenses by permanently changing the shape of the cornea (the delicate clear covering on the front of the eye).

??????????? In order for a person to be able to view images clearly, their eye?s cornea and lens must be able to refract light rays properly so that images are focused on the retina. If these light rays aren?t clearly focused on the retina, they will see blurry images. This blurriness is called a ?refractive error? and is caused by an imperfect eyeball, cornea or lens. LASIK helps solve this problem by using an Excimer laser which is an ultraviolet laser to precisely remove corneal tissue to correct the shape for better focusing.

??????????? LASIK eye surgery is often performed on people who have nearsightedness or myopia, but is sometimes used to correct farsightedness and astigmatism. By using the Excimer Laser, the technology is able to correct nearsightedness up to 12.00D with -4.00D of astigmatism, and farsightedness from +1.00 to +6.00 with 1.00D of astigmatism. (Diopter, symbol D, is the measurement of the refractive error. A negative D value indicates nearsightedness and a positive D value indicates farsightedness.)

Before having a LASIK eye surgery, a complete eye examination is done to make sure your eyes are healthy. Doctors will then make sure that there are no irregularities that would prevent having a LASIK by measuring the curve of the cornea, the size and position of the pupils and the shape of the eyes. They will also make sure that there will be enough tissue left after the cornea is cut and reshaped by measuring the thickness of the cornea. The surgical procedure takes place within the consciousness of the patient, using only a mild sedative and anesthetic eye drops. The surgical procedure will take only 10 to 15 minutes for each eye and may be done on both eyes during the same session.

But before you think of going for a LASIK eye surgery, there are several things you must consider before undergoing the procedure. First of all you must be at least 18 years old since the vision of people younger than the age of 18 still continues to change. You should also not be pregnant or nursing and not taking certain prescription drugs that may interfere with the laser vision correction results. People with diabetes, rheumatoid, arthritis, lupus, glaucoma, or cataracts are not recommended to undergo the procedure as well. Mind that you should carefully weigh the risks and benefits based on your own personal value system and fully understand all the potential issues and complications.

LASIK is a good solution for people with nearsightedness and farsightedness. Surveys have also determined that most patients are satisfied with the results. You too may be satisfied from the procedure, but this only depends on your expectations and your research on the subject.

If you wear glasses or contact lenses, chances are you have thought or even looked into LASIK eye surgery. This surgery has taken the optical world by storm, it promises to let you leave your glasses or contacts in the past, or at least to lessen your dependence upon them. As the procedure becomes more popular, it is easier to find a doctor or an office that will perform the surgery for you.

Before you decide that LASIK surgery is right for you, make sure that you know all the facts, and how they might affect you. LASIK (laser-assisted in situ keratomileusis) is a surgery that changes the cornea shape, this is a permanent change that is made using a laser and a special knife. This is what allows you to become fewer dependants upon your glasses or contact lenses as most wearers suffer from a misshaped cornea.

Before the surgery, you will need to consult with an optometrist that specializes in LASIK surgery. The doctor will conduct a number of tests to determine if you are a good candidate for the surgery. If it is determined that you are a good candidate, the doctor should be able to tell you how much of a change in your eyesight can be expected after the surgery.

Several things are taken into consideration when a doctor evaluates you for the surgery. For example, if you have had a change in your eyewear prescription within the last year, LASIK is not for you. The eyes need to be stable for at least a year, preferably longer to ensure that they aren’t going to change shape on their own. If you have a history of certain diseases, LASIK may not be the right choice for you either. Having a history of Glaucoma, Herpes, eye injuries or thin corneas, are a few of the reasons that would disqualify you for the surgery.

Now you have been checked out by a doctor and are ready to proceed on your road to a future without glasses. It is important that you know what to expect during the surgery as well.

When you go in for the actual surgery, you will be placed in a reclined position. You will receive a numbing solution in the eye that is being operated on. The doctor will use a special speculum to hold the eyelid open and a large machine with a microscope will be aimed at the eye. A ring will be applied to your eye with hard pressure, this is to create a suction affect on the cornea, the doctor will the use a knife to cut the part of the cornea that needs to be reshaped. Your vision will be blurred during this part of the procedure.

After the cornea has been cut the ring is removed, at this point, you will be able to see, although this will come and go during the rest of the LASIK surgery. This is the part of the operation where the laser is introduced, two actually. The first laser is for your eye to focus on; the second is the working laser.

The machine with the microscope is also attached to a computer. This computer is what controls the amount of strength that is available in the laser. Before the procedure, the surgeon will have programmed how much tissue needs to be removed from the cornea, based on the tests in the first visit. The computer then, stops the laser when the exact amount of tissue has been removed.

Your surgery is essentially done! There are a few rules for after the procedure that your doctor will go over with you, but most people are back to daily life within a couple of days.

Being overweight, drinking a lot of alcohol and not eating right contribute to high blood pressure. The person may not notice anything wrong now but in a few years, this will come in the form of a stroke that could either kill or leave anyone paralyzed.

Studies reveal that this affects more than 50 million Americans with about 30% still unaware what could happen in the future.

There are no symptoms to tell that a person has high blood pressure. Going to the doctor regularly can prevent this but those who don’t will experience things such as headaches, dizziness and nose bleeds which could already mean something is wrong.

Pain in other parts of the body is another warning of imminent danger. Other red flags are excessive sweating, frequent urination, muscle cramps or even palpitations. Should any of these happen to the person, it will be a good idea to visit a physician to find out what is the problem.

Doctors can check on the blood pressure by wrapping a machine on the upper arm, inflating the cuff and listening to the flow of blood using a stethoscope. Normal blood pressure is around 120 over 80. Should this be 140 over 90 or higher, the person has hypertension. It isn’t hard to tell one has high blood pressure given the size of the patient. This is because doctors have a standard given an individual’s gender, height and age so those who are above that are at risk of high blood pressure.

The doctor has to go through the standard operating procedure of asking some personal questions, which includes the individual’s medical history. If this runs in the family and a blood test has confirmed the suspicions of the physician, a solution can be planned before it is too late. The only way to lower the high blood pressure will be for the person to make some lifestyle changes. This usually includes eating healthy, and exercising with the objective of losing those excess pounds so the good cholesterol in the body is balanced against the bad cholesterol.

The person will also have to quit smoking and giving up the daily consumption of alcohol. Headaches lead to dizziness up to the point that some people feel nauseated or want to just faint. This can be fatigue or high blood pressure that is a warning of something bad that could happen if proper action is not taken so change must happen to make the blood pressure normal.

WHEN HEADACHE BECOMES SEVERE

Although headache is quite common to many people, experts say that people should not ignore headaches especially if they become severe. Based on medical findings, the most common symptom of severe headache is related to a migraine attack caused by the dilation of blood vessels on the brain.

Severe headache usually leads to vomiting, distorted vision, nausea, dizziness, and the like. What you can do is to take over-the-counter medication such as oral analgesics like aspirin, ibuprofen, or paracetamol can provide relief and are best if taken as soon as symptoms start to occur.

But when the headache becomes worse, make sure that you visit your health care provider because it can also be an indication of more serious illnesses like meningitis or the inflammation of the meninges or membrane around a person’s brain; sub-arachnoid haemorrhage due a bleeding in the space between the brain and the arachnoid layer of the meninges, stroke, blood pressure, brain tumor, and temporal arteritis due to the inflammation of the arteries in the scalp.

Other causes of severe headache migraine, a condition that occurs and recurs in patterns; sinusitis that is a severe pain experienced behind your cheek bones or above the bridge of your nose usually associated with a blocked nose. steam and painkillers that should relieve the symptoms but if taken in wrong dosages can lead to severe and throbbing pain, fevers that are untreated like flu, tonsillitis, chest infections and the like, neuralgia or due to the irritation of the nerve that produces pain sensation in response to outside activities, and glaucoma or other acute eye problems that most of the time lead to severe frontal headaches and deteriorating eyesight.

Heath care experts agree that using any medication should only be part of a wellness program. They also agree that successful treatment of chronic headaches should be combined approaches of medication and life-style changes like avoiding any listed headache triggers, personal and family counseling, stress management, and relaxation therapies.

In order to treat any type of headache, it is a must that you know what causes it. Before taking in any painkillers or undergoing any headache treatment procedure, make sure that you have consulted with your physician or health care provider first so he/she can give you the appropriate prescription or can give you a referral to appropriate experts if your headache is caused by any other disorder.

Beauty lies in the eyes of the beholder- yes; your eyes are a vital pair of sensory organs that the above statement partially describes their purpose.

Eyes are highly sensitive organs that demand a lot of care and attention and it does not require to be told the importance of this visual asset. Of course, individuals cannot determine the requirement of eye surgery, it is the job of an ophthalmologist who are skilled professionals having the license to carry out a surgical procedure on your eyes based on the diagnosis.

When do you need eye surgery?

Eye surgery has different terminologies such as orogolomistician aka ocular surgery is rather a very complex procedure that requires professional acumen. The most common eye surgery is the cataract, which is carried out normally on aging people due to the crystalline lens getting cloudy and barring the light to create a clear picture on the retina. Based on the severity of the situation the ophthalmologist will be able to guide you with the suitable surgical procedure. Glaucoma is another medical condition that damages the optic nerve and might result in visual loss but the different glaucoma eye surgeries can certainly help you to combat the disease.

Then you also have the refractive surgery that will correct the refractory errors in the eye to avoid the use of lenses. The other common kind of eye surgery is Eye muscle surgery that basically alters the strabismus and involves many more corrective measures. Eye surgery is also performed on repair fractures due to injury, to remove tumours and even as a facelift measure that solely depends on the ophthalmologist to decide the kind of surgery you need based on the problem.

Lasik Eye Surgery

Lasik eye surgery is the gift of science to mankind, as it is efficient in rectifying vision. People with conditions of astigmatism and myopia are largely opting for laser eye surgery, which has high percentage of positive results and the nature of the surgery itself is simple and painless that draws so much popularity. Lasik is the laser eye surgery that involves least complicated procedure, which removes the corneal tissue accurately and reshapes the cornea to gain more power while focussing. The Laser eye surgery has broken the conventional barriers of using glasses or lenses as vision corrective measures.

Precautions before eye Surgery

Before going for eye surgery it is necessary for individuals to disclose to the doctor if they have any infections or allergies so that the existing conditions can be treated first to avoid further complications. Even your physical conditions also play a major role so it is safe to bring to the notice of your ophthalmologist before the eye surgery so that he can take a suitable decision.
