Uncontrolled diabetes causes a host of problems in the body, one of which is eye problems or loss of sight. The blood vessels in the eyes are the smallest in the entire body and are susceptible to many vascular problems. When someone has high blood sugars that are not kept within normal ranges of between 80 and 100 milligrams per deciliter or mg/dL (fasting levels), the vessels in the eyes can become damaged.

Cataract surgeons are buzzing about femtosecond laser cataract surgery, a new technology aimed at helping surgeons achieve better results with toric and multifocal IOLs.

Traditional cataract surgery is already pretty successful, but the lasers deliver a benefit that's difficult to achieve with traditional techniques. They can create a perfectly round, perfectly centered opening in the front of the bag that holds the cataractous lens. That's especially important for some specialty IOLs. When the capsulorhexis (the name for the opening in the anterior portion of the capsular bag) is too small, it can interfere with the performance of multifocal lenses like the Bausch & Lomb Crystalens and the Alcon Restor. When it's too large, it can cause any intraocular lens to tilt and push forward, particularly troublesome for toric and multifocal lenses.

Monovision can be a viable solution for LASIK patients older than 40 years, provided they receive appropriate counseling and have reasonable expectations for success. Mature patients are involved in more activities requiring near vision, according to Elizabeth A. Davis, MD, who spoke at OSN New York

Many top athletes are turning to LASIK vision correction surgery to eliminate the need for glasses or contact lenses, and with good reason. For athletes, both eyeglasses and contact lenses can be a problem, despite special lenses and glasses

With careful patient selection and close monitoring, phototherapeutic keratectomy, PRK and LASIK can be viable options in specific cases. PARIS — Keratoconus is classically considered a contraindication for laser refractive surgery, and refractive surgery itself, especially LASIK, is known

It is one of the wonders of modern medicine and technology - the ability to improve vision and do away with spectacles or contact lenses. LASIK (short for laser-assisted in situ keratomileusis) has gained popularity over recent years, whether for aesthetics or for practicality. In fact, it is so popular that the Singapore National Eye Centre (SNEC) does some 5,000 procedures annually.

But questions and myths over this procedure still abound. Professor Donald Tan, medical director of the SNEC, answers some of the top misconceptions about LASIK.

If you have been diagnosed with nearsightedness or farsightedness, you may experience some blurry vision, especially when you are not wearing your glasses or contact lenses. But did you know you may also have a common condition known as astigmatism? Astigmatism can also cause blurred vision,

If your eyes tend to be dry you will typically be excluded as a LASIK candidate. That is because in creating the corneal flap which folds back and gives the treatment laser access to the deeper layer, some tiny nerves are usually cut. This is not deliberate; it is just virtually inevitable. They are

Expanded use of femtosecond lasers and wavefront technologies are at the forefront of corneal-based refractive surgery.

 

Individualized treatment is the goal of the latest technology in corneal refractive surgery, including the use of lasers and corneal inlays. However,

Advanced Medical Optics, Inc. (AMO) (NYSE: EYE), a global leader in ophthalmic surgical devices and eye care products, today announced that the National Space Agency has approved the company's LASIK technologies for use on U.S. astronauts. The decision was made following review of extensive military clinical data using AMO's Advanced CustomVue™ LASIK with the IntraLase® Method, which showed the combination of technologies provides superior safety and vision.

Approved for use on consumers almost 2 decades ago, more than 40 million LASIK procedures have been performed to-date, making it the most-common elective surgical procedure in the U.S. But it wasn't until LASIK developed into an all-laser procedure that it was approved for use on pilots, mission and payload specialists who face extreme, physically demanding conditions in space. The all-laser LASIK technologies, which utilize wavefront guided and femtosecond lasers, have also been cleared for U.S. military personnel, including most recently Air Force pilots.
