Drug-releasing contact lenses may provide correct and consistent dosages of medication for patients, according to findings published in Investigative Ophthalmology & Visual Science.

No scientific evidence supports the view that subtle eye or visual problems cause learning disabilities, according to a revised policy statement on learning disabilities, dyslexia, and vision issued by the American Academy of Ophthalmology.

Besifloxacin ophthalmic suspension 0.6% (Besivance, Bausch & Lomb) is a new topical ophthalmic antibacterial indicated for the treatment of bacterial conjunctivitis and administered via sterile ophthalmic drops.

Eduardo C. Alfonso, MD, is the new chairman of the Bascom Palmer Eye Institute, University of Miami Miller School of Medicine. Dr. Alfonso is the fifth chairman to be named in the institute's 47-year history.

A next-generation progressive addition lens (Definity, Essilor of America Inc.) features proprietary technology (Dual Add 2.0 ) and design in clear (Trivex) material and gray and brown (Transitions VI).

A new position statement has been released by the Joint Commission to clarify the interpretation of standards regarding steam sterilization.

Prevent Blindness Ohio (PBO), along with Prevent Blindness America (PBA), has named June as Vision Research Awareness month.

Researchers studying the molecular genetics of glaucoma are discovering new genes by applying high-powered technologies to their analysis of family pedigrees and looking for clues in animal models. These genetic discoveries are moving this field toward clinical applications.

A new hybrid contact lens (SynergEyes Multifocal, SynergEyes Inc.) is being offered for the management of emerging presbyopia.

The latest version of a proprietary femtosecond laser (iFS, Abbott Medical Optics) offers a 150-kHz repetition rate and expanded options for flap customization.

Thousands of military personnel receive PRK or LASIK every year. Among Air Force personnel, the procedures have proven to be remarkably safe and effective. Based on a 1-year case review conducted by four ophthalmologists deployed to Afghanistan and eight deployed to Iraq, the most common complication was patients deploying too soon after having had refractive surgery performed.

A retrospective case-control study comparing data from preoperative evaluations with a non-contact applanation tonometer (Ocular Response Analyzer, Reichert) suggest that this device may be useful in helping to identify eyes with forme fruste keratoconus at risk for post-LASIK ectasia.

Social networking sites are being explored as tools for medical education and communication. Internet and SMS technologies increasingly will play a role in the professional lives of doctors, says Ophthalmology Times' medical editor.

An advanced LASIK procedure that uses an excimer laser and femtosecond laser (CustomVue iLASIK, Abbott Medical Optics) is safe and effective, and it provides excellent refractive outcomes, based on 1-month results of an ongoing, multicenter, prospective, non-comparative evaluation of 20 patients.

Contact lens-related microbial keratitis accounts for significant vision loss and health-care expenditures each year. Early identification and treatment can help improve prognosis, but better diagnostic methods are needed. Research to understand the effects of soft contact lenses on tear film physiology may provide new insights on pathogenesis and prevention.

No statistically significant differences were found in the results of LASIK performed with two combinations of devices for femtosecond flap creation and excimer laser vision correction. Both systems produced excellent clinical outcomes. One combination (VisuMax and MEL 80, both Carl Zeiss Meditec), however, was associated with less scatter and more predictability for refractive outcomes than another (Allegretto Wave Eye-Q, Alcon Laboratories; IntraLase FS60, Abbott Medical Optics). Additional research is needed to determine what effect the two femtosecond lasers might have had on the results.

Data from patients enrolled in prospective studies evaluating treatment of low to moderate myopia with astigmatism using a toric IOL (Visian Toric Implantable Collamer Lens, STAAR Surgical), wavefront-guided (WFG) LASIK, or WFG PRK were compared in a retrospective analysis. Although some differences were identified, all procedures overall were associated with favorable outcomes.

The newest program of the ARVO Foundation for Eye Research is Women in Eye and Vision Research, launched at the Association for Research in Vision and Ophthalmology's 2009 annual meeting to further develop and strengthen the career paths of women who conduct eye and vision research.

Abbott Medical Optics said it has decided to halt future production of its newest ophthalmic viscosurgical device, 3% sodium hyaluronate (Healon D), citing concerns about the company's ability to ensure a continuous supply to the market.

Current topography-based methods for keratoconus screening have limitations. Researchers at Doheny Eye Institute have been working to develop a method for capturing focal thinning that is characteristic of keratoconus using optical coherence tomography-derived pachymetry maps. A method based on fitting the data to a Gaussian waveform is showing promise.

War veterans often confront many injuries during their tours, including vision loss.

The One Use-Plus microkeratome (Moria) equipped with the 90-µm head, which cuts an average flap thickness of ~100 µm, is a single-use solution for performing sub-Bowman's keratomileusis. It performs with excellent reproducibility, comparing well with the femtosecond laser, and creates high-quality, planar-like flaps and smooth stromal beds.

Terms such as quality, style, and value may not be typically associated with the specialty eyewear industry. Certain brands are crossing the divide and making an appearance in corporate and industrial settings to provide protection and aesthetics in one package.

Advanced optical coherence tomography (OCT) devices used in routine screening of refractive surgery candidates can enable clinicians to obtain better results or determine if there is a reason the surgery should not take place. Advanced OCT imaging can reveal anatomic features missed by other screening instruments.

Newly unemployed Americans and their families who have lost their health insurance coverage and who are taking Pfizer branded medicines, including latanoprost ophthalmic solution (Xalatan), may be eligible for free medicine under a new patient assistance program launched by the manufacturer.

The French-American Chamber of Commerce (FACC) of Dallas/Fort Worth presented John Carrier, president of Essilor of America Inc., with the Alain Bellet Award.

The emerging trend toward the purchase of eyeglasses online is a threat for dispensaries. Even if the trend were to take hold, not everyone will choose to purchase eyeglasses online. Plan how your practice will react.

The custom topographic neutralizing technique seems to be a promising alternative for treating patients with aberrated corneas after refractive procedures. The procedure is performed using a proprietary topographically guided excimer laser (Allegretto Wave Eye-Q, Alcon Laboratories [formerly WaveLight]) and corneal topographer (Allegro Topolyzer, Alcon Laboratories [formerly WaveLight]).

A new optical coherence tomography (OCT) software application (Cirrus [high-definition] HD-OCT, Carl Zeiss Meditec) has been cleared by the FDA for commercial distribution.

The American Academy of Ophthalmology (AAO) and the American Society of Cataract and Refractive Surgery (ASCRS) have issued a joint statement regarding results of a new study. The new research reinforces an advisory issued in 2006 that cautioned patients taking tamsulosin (Flomax, Boehringer Ingelheim Pharmaceuticals Inc.) to treat prostate enlargement and urinary problems should inform their ophthalmologist about use of this alpha-blocker before undergoing eye surgery.
