How to Choose a Refractive Surgeon
The key to safe, successful surgery in any field of medicine is an informed patient with realistic expectations and a skilled, experienced surgeon. Take the time to research not only the procedure but the surgeon and the laser center you are considering for correcting you vision. Ask questions! Don't let cost be your deciding factor. The following guidelines can help you make the right choice to ensure the outcome that you are hoping for. Read more.
New Lens for Cataract Patients - Greater Eye Protection with Blue Blocker
I tell my patients to get good quality, UV-blocking sunglasses to protect their eyes as sunscreen protects skin.
Patients with lens replacements due to cataracts have had a built into UV protection in their intraocular lens. Now a new intraocular lens filters both UV and blue light.
An intraocular lens, or IOL, is a permanent plastic lens that is implanted in the eye during cataract surgery to replace a damaged crystalline lens. All IOLs filter ultraviolet light, but the ACRYSOF® Natural IOL takes the next step, filtering the harmful blue light, to more closely mimic what the natural crystalline lens does.
Researchers believe that blue light may cause damage to the retina, which could potentially contribute to macular degeneration or loss of vision. Recent advances in artificial lens material now address this concern for cataract patients.
It is likely that blue-light filtering IOLs will become the new standard for cataract lens replacement.
While some blue light waves contribute to color perception, other wavelengths of blue light may be harmful to your eye. There are many sources of blue light in your everyday environment including sunlight and artificial lighting.
IOLs are usually clear. The new ACRYSOF® Natural lens is transparent yellow. The yellow color is necessary to filter blue light. The tint is not visible and does not alter the natural colors of the things you see or the quality of your vision.
This new lens offers improved correction for all cataract surgery patients. It could be particularly helpful to specific patient groups: those who are very young with cataracts, have macular degeneration or a history of a macular disorder.
If you have cataracts, ask your ophthalmologist about the new blue-blocking lens to see if it might work for you.

 Cataract Treatment: Dr.Omphroy Led Breakthrough Lens Treatment in Hawaii
Cataracts are one of the leading causes of poor vision in the world, particularly in people over 60. A cataract occurs when the natural lens in the eye becomes cloudy. Treatment involves surgically removing the clouded lens and replacing it with an artificial intraocular lens.
In the past these implanted lenses were limited to a single focus or "monofocal". If the lens was implanted to correct distance vision, eyeglasses would still be required for near vision.
The Allegran ARRAYR Multifocal Intraocular lens corrects vision for both near and far distances. What is extraordinary about this procedure is that the ARRAYR lens works like a set of complex bifocals, reducing the need for eyeglass dependence. The tiny silicone lens has five built-in rings that provide differing levels of long-range and short-range focus. The soft silicone lens is foldable, allowing incisions during surgery to be significantly smaller, which means more rapid recovery.
The US clinical trials were impressive. In 1997, the year that the Federal Drug Administration approved the lens, 41 percent of patients with the ARRAYR lenses never needed glasses for any reason compared to 11 percent with monofocal lenses. This independence of glasses extends to both near-task use and distance vision.
The lens became available in the US market in March 1998 and Dr. Omphroy became the first ophthalmologist in Hawaii to implant one. While the lenses are exciting, they may not be for everyone, Dr. Omphroy says. Some patients with the ARRAYR lens report seeing halos around lights at night and complain of glare.
The risks and benefits of any eye surgery should be carefully considered. We are happy to discuss the merits and issues with this procedure and others.
