The future of cataract surgery is looking bright
The FDA just approved the RxSight Light Adjustable Lens (LAL). It’s the first intraocular lens (IOL) that can be adjusted after cataract surgery, to correct for any uncorrected prescription after surgery and healing. Instead of prescribing glasses after cataract surgery, doctors can now perform an office-based procedure to apply the patient’s prescription directly into the adjustable intraocular lens.
How does the LAL work?
It contains monomers that are sensitive to UV light of a certain wavelength. If there is uncorrected prescription 17 to 21 days after cataract surgery, the lens is irradiated at a targeted area which will change (and correct) the prescription. In fact, it can correct up to 2 diopters of sphere (myopia or hyperopia) or cylinder (astigmatism).
How does the treatment work?
Patients undergo three or four UV light treatments over the course of one to two weeks, lasting approximately 40 to 150 seconds each treatment. Until the treatment is completed, patients must wear sunglasses to protect against the sun’s UV light, as this could cause the lens to change power.
New blood pressure guidelines are in place
The American Heart Association has released new blood pressure guidelines that determine who has hypertension (high blood pressure).
What are the new guidelines?
Previously, a blood pressure measurement over 140/90 was considered hypertensive. Now, anything over 130/80 categorizes you as having high blood pressure. This means an additional 14% of the US population (or 30 million people) now fall into the hypertensive group. According to these new guidelines, 46% of Americans have hypertension.
How does this affect me?
This does not automatically mean that more people need to be on medication. Unless the patient is high risk, patients will first be advised to improve their lifestyles (e.g., lose weight, eat healthier, exercise more, limit alcohol, and avoid smoking) rather than starting on medications.
December is Safe Toys and Celebrations Month
Did you know that roughly 1 in 10 children’s eye injuries that end up in the emergency room are caused by toys?
“You’ll shoot your eye out!”
In the holiday classic “A Christmas Story”, 9-year-old Ralphie Parker only wants one thing for Christmas – a Red Ryder Carbine-Action 200-Shot Range Model air rifle. When he tells his mother about his request, she says, “You’ll shoot your eye out.” He hears the same warning from his teacher and a department store Santa.
Ralphie ended up getting the BB gun that year, takes it outside and fires it at a target perched on a metal sign in the backyard. However, the BB ricochets back at Ralphie and knocks his glasses off. While searching for them, thinking he has indeed shot his eye out, Ralphie accidentally steps on his glasses and breaks them. Oh, Ralphie…
Safe toys = safe sight
In movies, scenes like this are hilarious! However, in real life, these kind of accidents aren’t so funny. In support of Safe Toys and Celebrations Month, parents should be cautious when choosing holiday gifts for young children (check out this safe toy’s checklist). Also, avoid toys that launch projectiles, such as crossbows, paintball guns, and BB guns. If an accident happens an eye injury occurs, seek emergency care from your local eye care professional to assess the extent of the damage.
