Cataract Surgery & Lens Implant Patient Satisfaction

If you have cataracts or are considering cataract surgery and lens implants, if you are a good candidate, it is pretty likely that your cataract surgeon will offer you the option of a multifocal lens implant in addition to the standard monofocal lens implant. The objective of using a multifocal lens implant to correct vision after cataract surgery is to help patients become less dependent or completely independent of glasses after their cataract is removed. A multifocal lens implant allows patients to see at a range of far, arms’ length and near without glasses whereas a monofocal will require the patient to still need glasses for most arms’ length or close vision tasks. Whenever we present or recommend this option to our patients they almost always ask, “Which one is better?” or “Which one will I be most satisfied with?” A multisite clinical trial was conducted and reported on in the Journal of Refractive Surgery that compared outcomes and patient satisfaction of monofocal vs. multifocal lens implants after cataract surgery. 

Results of Cataract Surgery with Monofocal vs. Multifocal Lens Implants
The results showed both monofocal and multifocal IOLs provided good clinical outcomes. More patients receiving multifocal IOLs attained better uncorrected visual acuity at a range of distances and spectacle independence compared with patients who received monofocal IOLs. Patient satisfaction was significantly better in the multifocal group.

Blood Thinners and AMD Hemorrhages

Many seniors take blood thinners for various types of cardiovascular and other vascular disease as a preventative measure for avoiding a heart attack or stroke. This same senior population is also at greatest risk for age related macular degeneration-including wet or hemorrhagic macular degeneration (AMD). Thus, the question of whether taking anticoagulants might be increasing the risk of and progression of AMD is important and reported on in a study published in Ophthalmology. The results showed that taking anti-platelet or anticoagulant medication was not significantly associated with macular hemorrhage and increased AMD risk unless the patient also had hypertension. 

If you or someone you know is taking blood thinners and at risk for age related macular degeneration (AMD) please call Eyecare Medical Group, 53 Sewall Street, Portland, Maine 04102 at 888-374-2020, visit Eyecare Medical Group, Google+ or to schedule an appointment.

Cataracts & Vitamin D

Vitamin D Helps Cataracts?
Cataracts continue to be a leading cause of vision decline in seniors as well as aging baby boomers. Those patients who do not yet have a cataract often ask if it is possible to reduce their risk or avoid cataracts with vitamins or diet supplement. Since Vitamin D has been shown to have an antioxidant effect it might seem like a good bet to reduce cataracts. But, the data continues to be confusing with regard to Vitamin D and cataract prevention. Researchers reporting in the Journal of Cataract & Refractive Surgery studied the impact and relationship between serum levels of Vitamin D and the risk of age related cataracts. They were able to eliminate the effect of other cataract risk factors such as age, sex, smoking status, diabetes, hypertension, and sunlight exposure. The results showed that in men, but not in women, the odds of developing age-related cataracts decreased with statistical significance when the serum Vitamin D levels were in the highest 10%  as compared to the when they were in the lowest 10%. But, it wasn’t a uniform trend throughout the range-only in comparison of the top to the bottom levels of serum Vitamin D levels. This, along with no real benefit for women makes the results warrant more study for now. Fortunately cataract surgery and lens implants offer a safe, effective and predictable treatment method with excellent results.

Tips for Solar Eclipse Eye Safety

A solar eclipse is one of nature’s most awe inspiring sights. By taking a minute to learn about solar eclipse eye safety precautions you can have a safe and memorable experience.

What is a Solar Eclipse?
On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun, or a “solar eclipse”. During a solar eclipse the moon will pass between the sun and the earth, actually blocking the sun either partially or completely depending on where you are viewing it from. This is a solar eclipse!  The blocking of the sun will last for up to three hours from beginning to end depending on your viewing location.  For this eclipse, the longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds.  The last time the contiguous U.S. saw a total eclipse was in 1979. This event turns day into night and makes the normally hidden solar corona-the sun’s outer atmosphere- visible! Bright stars and planets will become visible as well. This is one of nature’s most awesome sights. In the Portland, Maine area, we will have a partial eclipse, about 67%. The start time is 1:29 pm, the max eclipse is 2:45 pm and the end of the eclipse is 3:57 pm.

How Can You See It?
You never want to look directly at the sun without appropriate protection except during totalityBe aware of the risk that viewing a solar eclipse can present if you do not take the necessary eye safety precautions. Retinal burns, called “solar retinitis” or “solar retinopathy” can be produced by direct gazing at the sun. This rather serious problem is caused by the thermal effects of the visible and near infrared rays focused on the pigment structure behind the retina. We almost never see patients with solar retinopathy because the normal eye will tolerate only fleeting glances at the sun, but it can be fairly common during a solar eclipse.

However, there are many ways to safely view an eclipse of the sun including direct viewing, which requires some type of filtering device and indirect viewing where you project an image of the sun onto a screen.

The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses”. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun. To date four manufacturers have certified that their eclipse glasses and handheld solar viewers meet the ISO 12312-2 international standard for such products: Rainbow Symphony, American Paper Optics, Thousand Oaks Optical, and TSE 17.

A solar eclipse is one of nature’s grandest spectacles. By following these simple rules, you can safely enjoy the view and be rewarded with memories to last a lifetime:
·        Always inspect your solar filter glasses before you use them. If they are scratched or damaged please discard them. Read and follow any instructions printed on or packaged with the filter. Always supervise children using solar filters.
·        Stand still and cover your eyes with your eclipse glasses before looking up at the bright sun. After glancing at the sun, turn away and remove your filter — do not remove it while looking at the sun!
·        Do not look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device. Please do not look at the sun through a camera, a telescope, binoculars, or any other optical device while using your eclipse glasses because the concentrated solar rays will damage the filter and enter your eyes and potentially causing serious injury. Also, you should seek expert advice from an astronomer before using a solar filter with a camera, a telescope, binoculars, or any other optical device.
