What are Extended Wear Contact Lenses?

Most contact lenses are supposed to be removed during the night. The reason? Contact lenses tend to reduce the oxygen to the cornea, which can result in an infection. If you would like to wear contact lenses continuously (day and night) , you can choose extended wear contact lenses. These contact lenses allow the supply of oxygen to cornea, as a result you can use the lenses continuously (24 hours a day) for a period of 7 days or more.

What are Extended Wear Contact Lenses?

Extended wear contact lenses can be worn continuously (day and night). They can be used for a period of 7 days. Some of them can also be used for 31 days (or 30 nights). 

After this period, these lenses can be disposed and replaced by a new pair of lens.

Extended wear contact lenses are made of silicone hydrogel. This material provides transmission of oxygen through the lens, and then to the cornea.

Problems with earlier contact lenses

In 1981, FDA had approved some contact lenses for continual wear. However, these lenses reduced the oxygen supply to the cornea.

When oxygen supply is reduced, the eye would be unable to fight the microorganisms.

This can increase the risk of eye infection. As a result, eye care specialists advised the patients to remove the lens before sleeping.

In contrast to the old lenses, the newer extended wear contact lenses are made of silicone hydrogel.

This material allows the supply of oxygen to cornea and is safe for continuous wear.

If you are interested in extended wear contact lenses, do consult your eye doctor for the lens which suit you. While some may be suitable for 7 day continual wear, others would be suitable for 31 day continual wear.

What is Microvascular Cranial Nerve Palsy Symptoms (MCNP)

Cranial nerve palsy is a condition which involves one, two or more cranial nerves. Paralysis of a muscle generally leads to this problem. Cranial nerve palsies are quite easy to determine, as they involve the face muscle. Due to palsy, the face of the person also changes. A person affected with this, may find it troublesome to smile, control movements of the eye and other facial expressions.

From the brain, twelve pairs of cranial nerves are distributed to different areas of the face. These nerves run through holes present in the skull which are known as foramens. The cranial nerves controls the facial muscles, It is because of these facial muscles, people make various eye movements etc. A patient with cranial palsy, loses control over one or more muscles thus, leading to paralysis, drooping, or erratic uncontrolled movements

b) During a surgery, due to negligence, the cranial nerves can get damaged leading to cranial nerve palsy.

c) Some conditions for example, multiple sclerosis is also one of the causes of cranial nerve palsy as it damages the nerves. Other conditions are meningitis, diabetes, high BP etc.

Additionally, Following are the points causing defects in vision:

• Poor nutrition
• Working continuously for longer periods on system.
• Hormones.
• Excess stress may contribute to seborrheic belpharitis.
• Inadequate sitting positions while watching television.
• Bad settings of lights in the study room.

Treatment of Cranial Nerve Palsy

The treatment for Cranial nerve palsy relies on finding out the cause and approaching it. In a few cases, it is not possible to reverse the condition because of nerve damage. In a few other cases, the patient may regain muscle control. Seeking the help of a physical therapist helps the patient in gaining muscle control and developing coping skills. It is important to visit a neurologist very often to see the progression of the condition.

1) When there is a change in facial movements or expressions, consult a neurologist immediately.

2) Examinations are conducted to find out the damaged cranial nerve or nerves.

3) Make sure you provide the patients complete history, as even the smallest information is very important for the diagnosis.
