Blue Light Blocking Lens Implants

Patients Won’t Lose Sleep Over Blue-light-blocking Lens Implants

A new Australian study looked at whether blue-light-blocking intraocular lenses (IOLs) would disrupt sleep patterns in patients who had this type of lens implanted after cataract removal.  Blue-light-blocking IOLs are often prescribed as part of risk-reduction for age-related macular degeneration (AMD) for susceptible patients.  However, blocking blue-spectrum light had the potential to affect the production of melatonin, which is important for sleep regulation. The researchers followed 49 patients, 18 with blue-light-blocking IOLs, comparing them to the 31 patients who received conventional IOLs, at six months after surgery.  The final results showed no affect on people’s sleep patterns or sleep quality in the patients with blue-light-blocking lenses.

Taking Flomax May Cause Cataract Complications

Taking Flomax May Cause Cataract Complications

A new study confirms the link between patients taking Flomax and complications when undergoing cataract surgery. Men taking Flomax to treat an enlarged prostate face more than double the risk for serious complications should they need cataract surgery. In this new study, 7.5 percent of the men who had taken Flomax in the two weeks before cataract surgery had a serious complication, compared with 2.7 percent of those who had not taken the drug. That makes it a 2.3 times greater risk. This study strengthens an existing study from 2005 about risks associated with taking Flomax before cataract surgery. The 2005 study found that men taking Flomax or other alpha-blockers before cataract surgery had complications during and immediately after the procedure.

Flomax is often prescribed to treat an enlarged prostate, a condition known as benign prostatic hyperplasia, or BPH, which affects almost three of four men 70 and older. Women are also prescribed Flomax, for urinary problems. Anyone who is taking or has ever taken Flomax or a similar alpha-blocker should tell his or her ophthalmologist prior to cataract surgery. If you have cataracts and know you will need cataract surgery, you should consult with your prescribing physician before starting to take any alpha-blocker. Do not discontinue taking an alpha-blocker without talking to your doctor.

Keep an Eye on UV Safety

Keep an Eye on UV Safety
NAEPS offers tips for safe fun in the sun

As you rub sunscreen on to protect your skin this summer, don’t forget to protect your eyes as well. Summertime means more time spent outdoors, and studies show that exposure to bright sunlight may increase the risk of developing cataracts, age-related macular degeneration (AMD) and growths on the eye, including cancer.

June is UV (ultraviolet light) Safety Awareness Month, and the Nebraska Academy of Eye Physicians and Surgeons wants to remind Nebraskans of the importance of protecting their eyes from the sun’s harmful rays by wearing proper protection. They also wants to remind the public of the importance of protecting eyes from indoor UV light when using tanning beds.

“UV radiation, whether from natural sunlight or indoor artificial rays, can damage the eye’s surface tissues as well as the cornea and lens,” said Thomas Graul, MD. “Unfortunately, many people are unaware of the dangers UV light can pose. By wearing UV-blocking sunglasses, you can enjoy the summer safely while lowering your risk for potentially blinding eye diseases and tumors.” It is important to start wearing proper eye protection at an early age to protect the eyes from years of ultraviolet exposure.

“Your eyes are at risk from the sun year-round,” says Dr. Graul  However, the longer the exposure to bright light as happens frequently during the summer, the greater the risk is. Excessive exposure to UV light reflected off sand, water or pavement can damage the eyes’ front surface. In addition to cataracts and AMD, sun exposure can lead to lesions and tumors that may be cosmetically unappealing and require surgical removal. Pinguecula, tiny yellow bumps on the eye, are common from too much UV exposure. They begin on the white part of the eye and may eventually disrupt your vision.

Damage to the eyes from UV light is not limited to the outdoors; it is also a concern with indoor tanning beds. “Tanning beds can produce UV levels up to 100 times what you would get from the sun, which can cause very serious damage to the external and internal structures of the eye and eyelids,” according to Dr. Graul. “Corneal burns, cataracts, and, in rare instances, retinal damage can occur.” It is critical that you wear the properly designed goggles for use in tanning booths to protect the eyes.

The Nebraska Academy of Eye Physicians and Surgeons offers these tips to protect your eyes from the sun:

  • Don’t focus on color or darkness of sunglass lenses: Select sunglasses that block UV rays. Don’t be deceived by color or cost. The ability to block UV light is not dependent on the price tag or how dark the sunglass lenses are.
  • Check for 100 percent UV protection: Make sure your sunglasses block 100 percent of UV-A rays and UV-B rays.
  • Choose wrap-around styles: Ideally, your sunglasses should wrap all the way around to your temples, so the sun’s rays can’t enter from the side.
  • Wear a hat: In addition to your sunglasses, wear a broad-brimmed hat to protect your eyes.
  • Don’t rely on contact lenses: Even if you wear contact lenses with UV protection, remember your sunglasses.
  • Don’t be fooled by clouds: The sun’s rays can pass through haze and thin clouds. Sun damage to eyes can occur anytime during the year, not just in the summertime.
  • Protect your eyes during peak sun times: Sunglasses should be worn whenever outside, and it’s especially important to wear sunglasses in the early afternoon and at higher altitudes, where UV light is more intense.
  • Never look directly at the sun. Looking directly at the sun at any time, including during an eclipse, can lead to solar retinopathy, damage to the eye’s retina from solar radiation.
  • Don’t forget the kids: Everyone is at risk, including children. Protect their eyes with hats and sunglasses. In addition, try to keep children out of the sun between 10 a.m. and 2 p.m., when the sun’s UV rays are the strongest.
