Medications
The mainstay of glaucoma treatment in its early stages is the use of eye pressure lowering eye drops. These medications commonly work by decreasing the amount of aqueous humor fluid produced by the eye, effectively "turning off the tap" of eye fluid and thereby helping to lower the eye pressure. Other glaucoma eye drops work by causing more fluid to drain out of the eye. Most glaucoma can be slowed greatly or even halted with the use of eye drops alone.. ...
Soft Toric Contact Lenses
Contact lenses (contacts) are corrective lenses that are worn directly on the eye. Soft contacts are made from a plastic called hydrogel and are about 35‰ to 80‰ water. Water makes the lenses flexible, comfortable and allows for oxygen permeability.. Contact lenses rest on the cornea. The function of the cornea is to focus light onto the retina. The cornea does not have blood vessels so it gets oxygen directly from the air. Since soft contact lenses cover the entire cornea an adequate amount of oxygen must pass through the contact to maintain the health of the eye.. Only an optometrist or ophthalmologist should fit soft contact lenses. To determine if contact lenses are an option for a patient, the eye doctor will perform a complete eye exam and measure the curvature of the cornea. The eye doctor may need to use trial lenses of several different brands, materials, powers and sizes before finding the best lens for each patient. An eye care professional will demonstrate proper insertion, ...
IMPROVE YOUR VISION

Multifocal
The main advantage offered by multifocal lenses is the opportunity to become less dependent on reading glasses for near activities. Activities that were once easily enjoyed without glasses, such as reading or sewing, now require that a pair of reading glasses always be available. For people frustrated by the need for reading glasses, multifocal lenses offer a good alternative.. For example, in the FDA trial of the ReSTOR multifocal lens, 84% of ReSTOR patients achieved simultaneous 20/25 distance vision, which is a single line away from perfect 20/20 vision, and near vision that allowed newsprint to be easily read. However, only 23% of patients with monofocal IOL lenses in the same study were able to achieve those levels of distance and near vision simultaneous. The clinical trials for the ReZoom multifocal IOL and Crystalens accommodating IOL also demonstrated markedly better simultaneous near and distance vision with these lenses compared to traditional monofocal IOLs.. The trade-off for ...
