Mucus is often produced because of inflammation in the sinuses, nose or airways. The most common cause of this every morning is because of an allergic reaction. Many people, even those without classic allergies, can have allergic symptoms. Common allergens include dust mites, pollen and dust.
LASIK is corrective surgery to a very delicate part of the eye. Millions of people have had LASIK surgery to correct their vision, many with great success. But everyone is not a good candidate for the surgery.
There are two main parts of LASIK surgery: 1. Creation of corneal flap. 2. Laser below the flap on corneal stroma bed to rectify the refractive error. For the first part either a blade (microtome) is used or specialised laser called âfemtosecond laserâ is used. With the laser, the cut is more precise and under direct visualisation, unlike with a blade, and hence more safe.
