A hydrophilic IOL (Afinity CQ2015, STAAR Surgical) seems to be a more efficient delivery system of moxifloxacin 0.5% (Vigamox, Alcon Laboratories) than a hydrophobic IOL (AcrySof SA60, Alcon Laboratories), according to the results of a comparison of lenses soaked in the antibiotic. Both lenses appear to be capable of delivering antibiotics to achieve clinically relevant levels, however.

A non-contact applanation tonometer (Ocular Response Analyzer, Reichert) appears to be more effective than the Goldmann applanation tonometer (GAT) in assessing very low and negative IOP values using the non-contact applanation tonometer's corneal-compensated IOP (IOPcc) parameter. The GAT may be the long-accepted gold standard, but the more accurate assessment of IOP using the non-contact applanation tonometer challenges this gold standard and raises questions as to which of the two techniques is optimal in measuring IOP.

Intravitreal triamcinolone (IVTA) for treating diabetic macular edema (DME) does not seem to be beneficial over the long term compared with focal/grid photocoagulation, and treatment with IVTA results in a higher chance of developing a cataract compared with treatment with the laser, according to a 3-year comparison study. Focal/grid photocoagulation, therefore, remains the most effective treatment for DME, according to one ophthalmologist.

A recent article in the Journal of the American Medical Association, an editorial in American Family Physician, articles in the general media outlets, and an updated patient advisory statement from the American Society of Cataract and Refractive Surgery and the American Academy of Ophthalmology aim to further education primary care physicians and patients about the association between a patient's use of tamsulosin and complications or difficulty during cataract surgery.

One resident wonders, what does your Ophthalmology Knowledge Assessment Program score say to others about you as a resident? With the exception of applying to oculoplastics fellowships, in the global scheme of things, it may make no difference. On the other hand, some residents wished they had done better because they would have been thought of more positively within their program.

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.

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).

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.

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.

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.
