Lagophthalmos is the inability to fully close the upper eyelid. It is a form of facial paralysis affecting the obicularis muscle in the eyelid and it usually affects only one side of the face. With incomplete lid closure your eye is constantly exposed to the drying effects of outside air as well as to dust particles and debris. This may result in ch...

| Lagophthalmos: Incomplete Eye Closure |
Our eyelids act as protective covers for the eyes, especially during sleep; during the day they are important for spreading the tears evenly over the ocular surface, keeping it moist and comfortable.
During a blink, a thin film of tears is spread evenly over the surface of the eyes, which helps maintain a very smooth surface for clear and undistorted vision. The tear film is also a source of necessary nutrients and protects the cornea from infections; a full and complete blink is necessa...

Laser Capsulotomy
A laser is a high-tech device that produces very high-energy light beams that can cut tissues in certain types of surgery. Most cataracts are removed surgically by a method called extra-capsular cataract extraction. In this procedure the front part of the capsule – the membrane enclosing the cataract – is opened and the cloudy lens is removed; the back part of the capsule is left in place to support a plastic intraocular lens (IOL). Many months or even years after ...

LASIK Surgery: Am I a Good Candidate?
Refractive surgery has made great strides during these last few years, both in the accuracy of its results and in its overall safety. It has become extremely popular with people who are nearsighted, farsighted or have astigmatism because it greatly reduces their dependence on their eyewear, either contact lenses or glasses. However, it is still surgery, and must be treated as such, not as if it is merely a cosmetic issue.

Farsightedness medically termed as hyperopia (hi-per-O-pe-ah) is a common condition that affects approximately 25 per cent of the adult population. It refers to a vision problem in which the focusing power of the eye is too weak. This type of refractive error usually results in difficulty when focusing on close objects but depending on the severity can also affect distance vision as well. Farsightedness occurs when the eyeball is too short as measured from front to back or if the curvature o...

| Lead Exposure May Cause Cataracts |
Common sources of lead include leaded gasoline paint water contamination and air pollution. A study has found a link between lead exposure and the development of cataracts in older men adding to the list of harmful effects blamed on the heavy metal. To measure the men s long-term cumulative exposure to lead the researchers analyzed their shin bones where lead is believed to remain for up to 20 years.
The men with the highest lead levels were found to be 2.7 times more likely to have cataracts ...

| Leafy Green Vegetables Help Prevent Cataracts |
Lutein and zeaxanthin were nearly 10 times more powerful than vitamin E in protecting the cells from UV-induced damage. A new study from Ohio State University provides the first laboratory evidence that certain antioxidants found in dark leafy green vegetables can indeed help prevent cataracts. Vitamin manufacturers often add the antioxidants lutein and zeaxanthin to their products but until now there has been no biochemical evidence to support the claim that these substances help protect the ey...
