Chicago—A consortium of German researchers is making considerable progress toward development of an implantable device for 24-hour monitoring of IOP, according to Peter Walter, MD.

American ophthalmologists have a number of meetings each year they can choose to attend to hear the latest advances in the practice of eye care.

In the continual quest for a better understanding of vision, the Wilmer Eye Institute at Johns Hopkins University School of Medicine, Baltimore, is presenting its annual Current Concepts in Ophthalmology series.

Rogers, AR—The recent approval of the Tecnis IOL (AMO) on an acrylic platform gives cataract surgeons another option in an expanding menu of choices, said Randy Cole, MD, FACS, who is medical director and founder of Boozman-Hof Eye Surgery and Laser Center, Rogers, AR.

Vienna, Austria—A sharp posterior optic edge design seems to be superior to a double round optic edge design in preventing posterior capsule opacification (PCO). Investigators reported significantly less PCO at 1, 2, and 3 years after implantation of the Sensar OptiEdge AR40e IOL compared with the Sensar AR40 model (both from AMO).

The development of IOLs has come full circle. In 1949, Sir Harold Ridley attempted to emulate the curvature and size of the natural lens with the development of the Ridley IOL. In subsequent years, the focus was on IOL mechanical issues, materials, and optics. Today, with wavefront technology, researchers are going back to the beginning and are attempting to emulate some of the more subtle features of the natural lens.

Lisbon, Portugal—The results of the 7th annual survey on foldable IOLs indicate that dislocation and decentration are the most common reasons for lens explantation, with incorrect lens power the next most important factor.

A patient complained of severe glare and light sensitivity associated with a persistent traumatic mydriasis of the right eye. After conservative treatment with topical miotics and a painted contact lens failed to decrease the mydriasis, a cerclage pupilloplasty was performed on the right eye resulting in a 4-mm round pupil. The patient experienced significant reduction of glare and photophobia.

Leading edge programming on contact lenses, solutions, and related eye-care issues is the focal point of the fourth annual Contact Lens and Eyecare Symposium (CLES), Jan. 11 to 15, 2006, at the Royal Pacific Resort at Universal Orlando, FL.

Aliso Viejo, CA—eyeonics Inc. is reducing the number of implants it requires ophthalmic surgeons to perform before providing credentials for crystalens IOL implantation.

Irvine, CA—Allergan Inc. has offered to acquire Inamed Corp. for $1.45 billion cash and 17.9 million shares of Allergan stock to create a global leader in medical aesthetics.

Phoenix—Children with traumatic cataract often achieve a good visual outcome after cataract removal and primary IOL implantation, said Richard L. Golub, MD.

Fort Worth, TX—The FDA has approved Alcon's Opti-Free RepleniSH Multipurpose Disinfecting Solution (MPDS) for use with all soft contact lenses, including silicone hydrogel lenses.

While fluorescein angiograms and optical coherence tomography can assess structure, the retinal acuity meter looks at function.

Pleasanton, CA—MLI (formerly Massie Laboratories) has appointed Keith L. Mullowney as president, chief executive officer, and board chairman of the advanced diagnostic and data capture systems company.

Botulinum toxin type A (Botox, Allergan), originally approved by the FDA as an orphan drug for the treatment of strabismus and blepharospasm, has been found to be effective for the treatment of hemifacial spasm, Meige syndrome, nystagmus, and lid retraction in Graves? disease, according to Matthew Dean Kay, MD, adjunct clinical associate professor, Nova Southeastern University, Pompano Beach, FL.

Retinal detachment is a significant risk in refractive lens exchange surgery, said Emanuel S. Rosen, MD, at the refractive surgery subspecialty day meeting sponsored by the International Society of Refractive Surgery of the American Academy of Ophthalmology.

Reading, MA—Selective laser trabeculoplasty (SLT) is safer than argon laser trabeculoplasty (ALT) as a treatment for primary open-angle glaucoma (POAG) and offers the considerable advantage of not causing structural damage to the trabecular meshwork, said Mark A. Latina, MD.

With the instrumentation enhancements, it is easier for the surgeon to deal with peripheral pathology.

Doubts and concerns regarding efficacy and safety often accompany the introduction of technologies in IOLs. Recent concerns with a wavefront-corrected IOL (Tecnis, Advanced Medical Optics [AMO]) with regard to tilt and decentration are no exception to this rule.

Adelaide, Australia—Ophthalmic laser manufacturer Laserex has appointed Simon Luscombe as vice president of sales, Asia, in an effort to increase its Asian market share. Luscombe previously was in product management and sales management positions at Alcon and Advanced Medical Optics.

Tampa—Toric IOLs are a valuable tool in the cataract surgeon's armamentarium for correcting all levels of astigmatism, said James P. Gills Sr., MD, at the Current Concepts in Ophthalmology meeting.

Baltimore—Ethylene diamine tetra-acetic acid (EDTA) chelation offers a low-tech, low-cost, effective treatment for calcific band keratopathy associated with chronic uveitis and other disorders, said James P. Dunn, MD, at the Current Concepts in Ophthalmology meeting, sponsored by Johns Hopkins University School of Medicine and Ophthalmology Times.

Eyeonics has developed the crystalens SE System (Square Edge System), a modified design of the original crystalens accommodating IOL, which offers a 360? square-edge optic to help prevent posterior capsule opacification (PCO).

Edina, MN—When IOL piggybacking is needed, combining the modified prolate anterior surface IOL (Tecnis, AMO) with a conventional spherical IOL is a good option because it provides patients the added benefit of improved optical performance and better quality of vision, said Y. Ralph Chu, MD.

Washington, DC—A continuing rapid evolution in technology brings promise for the future availability of better surgical methods for correcting presbyopia, said W. Bruce Jackson, MD, at World Cornea Congress V.

San Francisco - A panel of glaucoma experts from across the United States highlighted the latest advances in understanding glaucoma and caring for these patients at “Glaucoma 2005: Mastering Tools and Techniques for the 21st Century,” on Saturday, Sept. 17, at the Ritz-Carlton San Francisco. Now in its 5th year, the program included lectures, panel discussions, and a mini-symposium covering a variety of glaucoma issues with a distinguished faculty.

Atlanta—Eye-care professionals are shifting their business from HEMA to silicone hydrogel lenses, according to data from Health Products Research.
