Implantable contact lens safe and effective for correcting myopia

02.09.2004


Implantable contact lens (ICL) to correct myopia, are safe, effective and have predictable results for correcting moderate to high myopia or nearsightedness. These are the conclusions discussed in an article published in the September issue of Ophthalmology, the clinical journal of the American Academy of Ophthalmology.

The article provided an update to the U.S. Food and Drug Administration’s long-term, follow-up multi-center STAAR Myopic Implantable Contact Lens (ICL) clinical investigation. The STAAR ICL is one of the lenses expected to receive FDA approval. A competing ICL, the Verisyse lens, to be sold by AMO Inc., has received approval by the FDA’s device panel and is also expected to receive FDA approval at about the same time.

For the study, the STAAR myopic ICL was implanted in 526 eyes of nearly 294 patients whose myopia ranged from -3.0 to -20.0 diopters. The lens was inserted through a tiny incision and placed in front of the eye’s natural lens. The study found that at three years, nearly 60 percent of the patients had 20/20 or better visual acuity and nearly 95 percent had 20/40 or better. Reports of symptoms such as glare halos, double vision, night vision and difficulty driving at night either decreased or remained unchanged. Ninety seven percent of the patients said they would chose ICL implantation again. Less than one percent of the patients said they were dissatisfied.


When compared with the refractive surgical procedure, LASIK, the ICL was found to be more effective for those with higher degrees of myopia. The study states, "These data suggest that the ICL should be given serious consideration for use in eyes with -7 diopters of myopia or more."

"While LASIK is the best surgical option for many patients, there can be more complications for patients with a higher range of myopia. Implantable contact lenses may be a good option for those patients," said Academy Spokesperson Peter Kastl, MD, Ph.D., professor of ophthalmology and adjunct professor of biochemistry at Tulane University in New Orleans.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
