• A prospective study of 237 dry eye patients conducted at four sites found that matrix metalloproteinase-9 (MM9) level, identified using the InflammaDry test, correlated with dry eye status. Results were compared to clinical assessment using tear break-up, Schirmer testing, corneal staining and the Ocular Surface Disease Index. The study was published in the August 2014 issue of Cornea.

• A new resource is available for clinicians seeking guidance with scleral lens fitting. Created by Michigan College of Optometry’s Vision Research Institute, the Scleral Lens Fit Scales demonstrate how to accurately estimate the amount of vaulting (clearance) under the posterior surface of a scleral lens by comparing the tear layer thickness to the center thickness of the lens. Additionally, optic sections demonstrate the tear thickness underneath the lens both centrally and at the limbal area, and various edge clearances are also shown.

• In August, CooperVision completed its acquisition of Sauflon Pharmaceuticals for approximately $1.2 billion. The deal will expand Cooper’s contact lens product portfolio, particularly in daily disposable options. 

Cooper also recently launched an e-commerce service called LensFerry, which allows contact lens wearers to order replacement lenses (from any manufacturer) online for home delivery. The prescribing practice receives the sales revenue “as if the lenses had been ordered in-office,” CooperVision says. More info is available at www.lensferry.com.
