Ketorolac tromethamine 0.45% (Acuvail, Allergan) is a preservative-free ophthalmic NSAID recently approved for twice-daily use in treating pain and inflammation after cataract surgery. Its novel formulation is designed to promote drug delivery and tolerability.

Researchers are looking into corneal biomechanics as a means to screen patients for keratectasia. An expert reviews signal interpretation from a non-contact applanation tonometer as it relates to corneal biomechanical indices such as corneal hysteresis and also discusses improved signal patterns that may result in more meaningful corneal biomechanical analysis than previously proposed metrics.

NeoVista Inc. received approval from BSI Product Services to apply the CE mark to its anti-neovascular (ANV) therapy system (Vidion) to treat wet age-related macular degeneration (AMD), the company announced.

The spherical aberration-free lens has been developed specifically for 1.8-mm microincision cataract surgery (MICS), and the company said it will refer to the lens within the United States as the Akreos MICS. Its award-winning design and glistening-free material allow implantation through a 1.8-mm incision, while maintaining the optical quality and stability established with the parent lens design (Akreos AO).

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.
