    Contact Lens Disinfecting Solutions and Contamination of Contact Lens Cases

    The authors describe the effect of various contact lens disinfecting solutions on the contamination of contact lens storage cases during use with silicon hydrogel lenses. Differences in contamination rates and types of microbes contaminating the cases were seen. A solution containing Polyquat and Aldox as the disinfecting agents resulted in reduced contamination by Gram-negative bacteria. (p. 456)

    Air-Drying Lens Cases, Up or Down?

    Limited guidelines are available regarding lens case air-drying positions and locations. The authors looked at the contamination levels in lens cases air-dried face up and down in four different house locations. It appears that air-drying lens cases face down minimizes air-borne contamination regardless of the drying location. (p. 465)

    Epithelial Roughness Alters Transparency Depending on Refractive Surgery

    Corneal transparency reduction is generally associated with disruption of the corneal stroma. In this study, the authors, using a novel method of assessing epithelial surface properties, show that corneal epithelial roughness contribution to transparency varies with corneal refractive surgical procedure.

    Novel Measures of Soft Contact Lens Surface Profile by Atomic Force Microscopy

    Precise knowledge of the shape profile of a contact lens surface, made possible by Atomic Force Microscopy (AFM), should give an idea of susceptibility to deposit formation or colonization by microorganisms. Using AFM, the authors introduce two new parameters that provide different yet complementary information about the roughness and topography of the contact lens surface. (p. 475)

    Sequential or Combined Penetrating Keratoplasty and Cataract Surgery?

    Refractive and visual acuity (VA) outcomes for sequential vs. combined procedures are compared. For refractive predictability, no significant differences are noted. However, sequential surgery tends to provide best-corrected VA and more patients achieving 20/40 vision or better. Other factors like the need for rapid visual rehabilitation, medical illnesses, and anesthetic risk are important for the patient. (p. 482)

    Vergence Adaptation Implicated in Positive Fusional Vergence Training

    Positive fusional vergence (PFV) can be trained with orthoptics. Models of accommodation and vergence predict that training PFV would require a reduction in the convergence accommodation (CA) cross-link. But recent studies find no change in the CA/C ratio cross-link. The authors' data suggest that these orthoptic programs may instead reduce CA through changes in the relationship between fast and slow vergence components. (p. 487)

    Increasing Eye Health Care Professionals Responsiveness to Low Vision Patients with Depression

    Depression often remains undetected in people with vision impairment. The authors test a brief and novel depression training program specifically for eye health professionals for interventions with their low vision patients. The training significantly improved eye care professionals' confidence in working with their low vision patients who suffer from depression, and reduced perceived barriers. (p. 494)

    A New Fast and Reliable Contrast Test

    Our authors describe a new contrast test (Star-Ring Test) using a computer program and monitor that appears to have novel features. They report reliability data that show considerable promise for the test in clinical testing. (p. 501)

    Tracking the Build-Up of Tear Film After a Blink

    By using a new approach to tear film measurement kinetics (lateral shearing interferometry), the authors are able to demonstrate the kinetics of all five different tear film phases following a blink, including two separate phases (fast and slow) of tear film build up. (p. 513)
