In patients overrepparttar age of forty it will probably be necessary to still wear reading glasses because they are required for problems other than cornea problems that can’t be treated by correctional treatment. As a general rule, though, if you have an eye problem that means you need to wear glasses to improve your sight and your sight has been at a steady level for 12 months or morerepparttar 147800 laser surgery should be successful.

The cost of Laser Eye Correction varies depending onrepparttar 147801 level of treatment you need and other determining factors but you can expect to pay between $800 and $1000 per eye. Usually, if you have both eyes done inrepparttar 147802 same visit (There are no known problems with choosing to do this) then you can expect to pay a little less.

The possible risks of Laser Eye Correction.

As with all surgery there are small risks associated with Laser Eye Correction.

There is a very low risk of infection, affecting only around 1 in 5000 patients. Most surgeons and clinics will provide you with a course of antibiotics and check ups to ensure that your eyes are reacting well torepparttar 147803 surgery.

An enhancement may be required to correct your vision if surgery leads to over correction or under correction. Again, this is rare but still possible because everyone’s eyes are different. Some are softer than others and some harder. This can lead to under correction or over correction.

During a short period after treatment you may experience seeing halos around objects when viewed at night, but this should normally clear up after a week or so. If you continue to experience these problems then consultrepparttar 147804 surgeon who completed your correction treatment for further advice.

If you directly touch or injure your eye immediately after surgery or within 24 hours you should consult your surgeon as this can lead to a shifting ofrepparttar 147805 flap that is created during treatment. A little care and attentiveness will prevent this from happening and almost any risk of shifting flaps is massively reduced after 24 hours.

Laser Eye Correction is now a mainstream treatment forrepparttar 147806 masses. Many people who wear glasses or contact lenses have considered Laser Eye Correction because it is a painless, easy procedure that will fix your eyesight and alleviaterepparttar 147807 need to wear glasses.

As with any surgery, there are risks associated withrepparttar 147808 treatment but they are minimal and consultation with your surgeon should allay any fears you may have.

The Pathophysiology of Tetanus

Written by Wong Lai Teng

Continued from page 1

The toxin acts afterrepparttar incubation period (3-14) days) at several sites withinrepparttar 147799 central nervous system, including peripheral motor end plates, spinal cord, brain and sympathetic nervous system. The typical clinical manifestations of tetanus are caused when tetanus toxin interferes with release of neurotrasmitters, blocking inhibitor impulses.

Blockade of spinal inhibition is produced whenrepparttar 147800 toxin acts atrepparttar 147801 synapse of interneurons of inhibitory pathways and motor neurons. General muscle rigidity arises from uninhibited afferent stimuli enteringrepparttar 147802 central nervous system fromrepparttar 147803 periphery. The effect ofrepparttar 147804 toxin onrepparttar 147805 brain is controversial; direct inoculation can cause seizures.

One ofrepparttar 147806 many complications from tetanus is respiratory failure secondary to spasms, obstruction by secretions, exhaustion and pulmonary aspiration. Cardiovascular complications thought to be due to hyperactivity ofrepparttar 147807 sympathetic nervous system include tachycardia, with heart rates over 180 beats per minute, severe vasoconstriction and hypertension. Autonomic dysfunction is seen as increased basal sympathetic activity and episodes of sympathetic over activity. (SOA).
