New Treatments For Your Vision

If you are used to wearing your eye glasses or contact lenses due to blurry vision due to a number of reasons like farsightedness, cataracts or nearsightedness ; prepare to put them away because there are new breakthroughs in the field of vision care. Over the years, new innovations like drugs, surgeries and new materials have come up to help you see better. Here are some common eyesight problems that has alternative ways of curing them.

1.) Age related macular degeneration - This is the breakdown of the macula which controls one's central vision. A new targeted therapy called Anti-VEGF ( vascular endothelial growth factor ) agents, Lucentis, Macugen and Avastin is injected to the back of the eye in while the patient is anesthetized to help stop central vision loss.

2.) Cataracts - This condition makes the eye lens cloud as you age so it makes if difficult for you to see. New lenses called Tecnis ZM900 and Alcon ReSTOR are multi focal intra ocular lenses (IOLs) are artificial implants that mimic the natural lenses giving suffering patients spectacle free distance and near vision.

3.) Glaucoma - Is caused by damage to the optic nerve that causes progressive loss of the field of vision. A new drug called Anecortave acetate is injected around the wall of the eye and appers to decrease production of myocilin, a protein that clogs the pore system inside the eye where fluids drains.

4.) Myopia - Also called nearsightedness in which objects in the distance appear blurry. A new pliable lens Phakic Implantable contact lens (ICL) is injected by an ophthalmologist into the eye where it unfolds to correct nearsightedness.

5.) Presbyopia - A condition in which the eyes lens loses its elasticity making nearby objects appear fuzzy. New glasses being developed called switchable bifocals will someday let you switch from near to farsighted vision at the touch of a button.
