Foresighted

Novartis Ophthalmics and Valley Forge Pharmaceuticals Inc. have entered into a licensing agreement for a novel eye medication for myopia, which in phase II clinical trials reduced progression of the disease by 50% in the first 12 months of therapy.

Sacramento-As a high-molecular-weight, high-viscosity cohesive viscoelastic, 1% sodium hyaluronate (UniVisc, CIBA Vision) protects the corneal endothelium during cataract surgery and IOL implantation and maintains the anterior chamber during sur-gical procedures.

Little Rock, AR-Research to Prevent Blindness (RPB) has awarded $110,000 to the University of Arkansas for Medical Sciences' (UAMS) Pat and Willard Walker Eye Research Center. The funds will be allocated toward research into the causes, treatment, and prevention of blinding diseases.

Cleveland-Ophthalmology Times is a finalist in two categories in the 49th annual Jesse H. Neal National Business Journalism Awards Competition. The prize is the most prestigious honor than can be bestowed upon the business-to-business media.

FDA approves faster laser pulse rate

The FDA approval of cyclosporine ophthalmic emulsion 0.05% (Restasis, Allergan) Dec. 26 marked a landmark for ophthalmology. The eye drop therapy for moderate to severe keratoconjunctivitis sicca is unique in that it treats the inflammatory process that causes the condition, and not just its symptoms.

Dallas-Preoperative, perioperative, and postoperative administration of topical antibiotics in 11,000 cases resulted in a remarkably low endophthalmitis rate (one case) in patients undergoing surgery to remove cataracts. It appears that meticulous attention to the use of antibiotics preoperatively, perioperatively, and postoperatively as well as placement of one suture across small-incision cataract wounds may be the elements that make the difference, according to James P. McCulley, MD.

Salt Lake City-An evaluation of four materials available for the manufacture of IOL haptics showed that polymethylmethac-rylate (PMMA), elastimide, and polyvi-nylidene fluoride (PVDF) had similar loop memory at a level that was significantly higher than that of polypropylene (PP) haptics. All lenses had a silicone optic.

Mainz, Germany-The accommodation capabilities of two IOLs (AT-45, CrystaLens, C&C Vision, Aliso Viejo, CA; and 1CU, HumanOptics AG, Erlangen, Germany) were clearly demonstrated in patients for the first time and compared with a standard IOL, which showed no accommodative effect, according to H. Burkhard Dick, MD.

Orlando-Custom prolate topographically guided corneal ablation using the LaserSight system with its unique ablation planning software (AstraPro) delivers improved overall vision, said Jack T. Holladay, MD, during the American Academy of Ophthalmology's refractive surgery subspecialty day meeting.

Orlando-The OPD-Scan optical path dif-ference scanning system (Nidek) combines measurement of corneal topography and aberrometry and could be particularly advantageous for guiding customized ablations in patients with highly aberrant cor- neas, according to speakers at the refractive surgery subspecialty day meeting prior to the annual meeting of the American Acad-emy of Ophthalmology.

Orlando-Ongoing formal and informal studies are examining expanded applications for conductive keratoplasty (CK), including its use for the treatment of presbyopia, astigmatism, and as an enhancement procedure for reducing hyperopia after previous keratorefractive or lenticular surgery, said Louis D. Nichamin, MD, at the refractive surgery subspecialty day meeting held prior to the American Academy of Ophthalmology annual meeting here.

Orlando-Results from international and U.S. FDA clinical trials point to the efficacy and safety of treating spherical and cylindrical refractive errors using the Zyoptix system for personalized vision correction (Bausch & Lomb), according to speakers at the refractive surgery subspecialty day held prior to the American Academy of Ophthalmology annual meeting.

Orlando-A new light-adjustable IOL (LAL) has been designed that will allow for noninvasive correction of residual refractive errors present after cataract surgery, said Daniel M. Schwartz, MD, during the refractive surgery subspecialty day meeting prior to the annual meeting of the American Academy of Ophthalmology. Researchers are ready to begin testing the LAL in clinical trials, he added.

Orlando-In the majority of eyes undergoing primary LASIK, wavefront-adjusted ablation performed with the WaveLight system yields visual outcomes comparable to those achievable with wavefront-guided techniques, said Theo Seiler, MD, PhD, at Back to the Future, the refractive surgery subspecialty day meeting prior to the American Academy of Ophthalmology meeting.

Orlando-CustomCornea wavefront-guided LASIK using the LADARWave aberrometer and the LADARVision4000 excimer laser (Alcon) last October became the first wavefront-guided LASIK system to receive FDA approval for the treatment of myopia. The agency's decision was based on clinical trial data proving that the customized approach delivers superior optical quality compared with conventional LASIK.

Orlando-The CRS-Master (Carl Zeiss Meditec) ablation profile design workstation is a "best of breed" platform for customized ablations because it integrates wavefront, topography, and clinical data for the individual patient while giving the surgeon control in designing the laser treatment, said Dan Z. Reinstein, MD, FRCSC.

Orlando-Six-month results from an FDA clinical trial indicate that customized wavefront-guided LASIK for treatment of myopia with the WavePrint system (VISX) is associated with safe and effective outcomes exceeding FDA targets. The wavefront-guided LASIK is also effective for minimizing increases in higher-order aberrations that can accompany conventional LASIK.

Orlando-Argon laser trabeculoplasty (ALT) can achieve substantial IOP reductions in patients with open-angle glaucoma that is refractory to medical therapy. In addition to efficacy, the cost of the procedure compares favorably with medical treatments, which tend to be substantially more costly over time, according to Karen M. Joos, MD, PhD.

The sky's the limit

Fort Bragg, NC-As a reward for helping a colleague with a difficult postoperative situation, Robert K. Maloney, MD, got thrown out of an airplane, literally.
