What's the latest in cataract surgery?

Cataract surgery is considered routine. It involves replacing the eye’s cloudy lens with a new artificial lens. Advances in technology include the use of lasers and 3D imaging, and intraoperative wavefront aberrometry, which measures the total refractive error of the eye. Medicare does not yet cover the costs of most of advanced cataract surgery technologies. Complications such as severe vision loss, bleeding, and infection are rare. Studies on animals have suggested that someday it may be possible to prevent and reverse cataracts with eye drops. (Locked) More »

Stay behind the wheel longer

Aging may affect vision, hearing, coordination, thinking, visuospatial skills, or reaction time, any of which can have a direct impact on driving. Driver assessment programs help people overcome weaknesses behind the wheel. Some programs take a team approach with social workers, occupational therapists, and neuropsychologists who evaluate a person’s driving history, family concerns, overall health, cognitive function, and driving reflexes. A road test is also involved. The team then recommends if it’s time to stop driving or brush up on certain skills. More »

Protect your vision from glaucoma

Glaucoma is a leading cause of vision loss among older men. Most cases are caused by high pressure inside the eyeball, which damages the nerve that connects the eye to the brain. People with glaucoma may also have eye pressure in the normal range, but the treatment is still to take medication, often in the form of eye drops, to reduce eye pressure. Detecting and treating glaucoma early can slow down vision loss. Some people may need extra help from laser or surgical procedures. It’s important to learn how to apply medications as instructed to get maximum benefit from drug treatment. (Locked) More »

Did youthful fun in the sun put you at risk for an eye condition now?

It’s debated whether sunlight directly causes common eye conditions. But there’s good evidence that sun exposure can cause an eye condition called exfoliation syndrome, which often leads to other problems. The condition leaves tiny dandruff-like flakes throughout the body, but mostly in the eye, where a buildup clogs the eye’s natural drains. The best way to stop exfoliation syndrome and other eye conditions from ruining vision is to catch them early with a comprehensive eye exam. (Locked) More »
