It is important to point out that there is often a misperception of the general public about the funding of biomedical and health-related research in the United States. While "the industry" does fund research into basic etiological insights into disease, a significant amount of funding comes from the National Institutes of Health, which has an annual budget of $31 billion. The US federal budget sequestration process includes across the board defense and domestic budget costs totaling $1.2 trillion set to occur over 10 years. There is no doubt sequestration will impact many aspects of our daily lives in addition to long-term insights that biomedical and health-related research provide us and our patients.

We received the following commentary from Tony Hough, BA, MBA related to Care Solution Corner columns on the evolving FDA standards for lens care systems published in Contact Lenses Today in October 2012 and February 2013.
Right about now, if you are a member, you will find the new British Contact Lens Association (BCLA; www.bcla.org.uk) contact lens standards leaflet arriving on your doormat. Writing this, I thought the approach to silicone hydrogels seemed worth a note especially following comments by Susan Gromacki in your newsletters of October 28, 2012 and February 10, 2013.
In ISO 18369-1:2006 a new fifth category for material classification is introduced, headed Enhanced Oxygen Permeable Materials (e.g. silicone hydrogel). This category in this standard has no content – it is waiting for further work. It is a placeholder standard – watch this space, as it were. But published ISO, ANSI and European Standards should not be about 'watch this space' – they should represent the consolidated results of established technology and methods; empty headings relating to information or methods which may accrue in the future do not belong in published standards. Oddly, the 'enhanced' oxygen permeability is a mere 30 ISO (hectoPascal) units – about 39 traditional units.
Then we look at the proposed further subdivision, summarized by Susan in your February 10 newsletter; it is necessary to know about the ionicity and if the material is surface treated. But we already have all of this in the existing system. For example, in the original BCLA standards leaflet published in 2000, one of the example materials is Focus Night & Day which I describe as Lotrafilcon A I 5 m; where Lotrafilcon A is the USAN name, "I" means it is non-ionic low water content, "5" means it has Dk 101 to 150 ISO units and the lowercase "m" at the end tells us it is surface treated such that the chemistry of the surface is different to the chemistry of the bulk. If we confine ourselves to contact lens interest does the proposed new structure tell us any more? It seems to me that the introduction of the fifth category as an empty placeholder was premature; the proposed further subdivision simply takes us back to the four we first thought of and which are established in the collective thinking of ECPs. We need to wait, probably for quite some time, to enable the technologies which surround silicone hydrogel materials to become properly established before we attempt to rewrite international standards, especially if the 'new' content adds little to our knowledge base. ^ Back to top

GSLS 2013 Report
This week's column is authored by my two Residents in Cornea and Contact Lenses: Dr. Crystal Remington and Dr. David Murakami.
Here are four lenses that were introduced at this year's Global Specialty Lens Symposium, each with its own unique features and advancements.
iSee (GP Specialists) is a new orthokeratology option that is capable of treating increased levels of myopia. Based on the Fargo design, it utilizes a more aggressive treatment zone to reduce up to 10 D of myopia.
UltraHealth (SynergEyes), the newest hybrid lens, brings together a high-Dk silicone hydrogel skirt and high Dk reverse geometry GP center in an irregular cornea design with a wide range of sagittal vaults, skirt curves, and powers.
Custom Stable (Valley Contax) is a new line of scleral contact lenses meant for normal, presbyopic and diseased corneas in 15, 16 and 18 mm. Custom Stable features NIMO power mapping analyzer, digital radius edge profile (DREP) to improve edge comfort, and laser etching for personalization.
The Europa Scleral lens (Visionary Optics) is an evolution of the Jupiter design. Its 'Universal Fit Technology' incorporates a larger optic zone, a new four curve peripheral design, and a reverse geometry curve in an 18 mm diameter to optimize scleral landing and corneal vault.

Advancements in Ocular Surface Imaging May Aid Keratoconus Diagnosis
With advancements in ocular surface imaging, there are new diagnostic methods that have promising ability to diagnose keratoconus.
The normal human cornea has a three-dimensional distribution of birefringence. Polarization sensitive optical coherence tomography (PS-OCT) has been developed that allows measurement and imaging of three tissue parameters simultaneously: reflectivity, retardation, and slow optic axis orientation in which conventional cross sectional, as well as en face images of thee parameters can be derived.1 The observed birefringence patterns in normal corneas can be used as standard patterns for comparisons with pathologic changes. It has been observed that in keratoconus corneas, the normal birefringence pattern is heavily distorted due to stacked collagen fibril lamellae of different orientations. This birefringence pattern has been used to discriminate keratoconus corneas from normals.
In 2007, Götzinger investigated 5 keratoconic corneal buttons with PS-OCT.2 The instrument measured backscattered intensity (conventional OCT), retardation, and (cumulative) slow axis distribution simultaneously. Three-dimensional data sets of the polarizing parameters were recorded, and two-dimensional cross-sectional images as well as en face images of the distribution of these parameters at the posterior corneal surface were derived. The results were compared to similar maps obtained from normal corneas. They found that compared with normal corneas, the retardation and slow axis orientation patterns were heavily distorted in keratoconus corneas. The observed changes in the cornea's birefringence properties indicated a change in the arrangement of collagen fibrils in the corneal stroma that is associated with keratoconus.
In the current issue of IOVS, Fukuda investigated the tissue properties of keratoconic and normal corneas in vivo using PS-OCT with the aim of discriminating early keratoconus.3 They evaluated 31 eyes with keratoconus, seven eyes suspicious for keratoconus, and 25 normal eyes and measured: average en face phase retardation of the posterior surface of the cornea, curvature, videokeratographic parameters, regular and irregular astigmatism, pachymetry map, and elevation. Each parameter was assessed to evaluate the diagnostic power to detect keratoconus and keratoconus suspects. In normal controls, the center of the en face phase retardation map showed low and homogeneous birefringence, but in keratoconic corneas the birefringence increased with disease severity. They concluded that the average of en face phase retardation of the posterior surface of the cornea was increased in keratoconus patients, and that this was sensitive enough to discriminate keratoconus suspects; they suggested that it might be useful for detecting subclinical keratoconus in the future.

Posterior Corneal Shape Changes In Myopic Overnight Orthokeratology
The researchers wanted to evaluate changes in the shape of the posterior cornea at the end-of-the-day based on anterior corneal topography and corneal thickness during myopic overnight orthokeratology (OK) over 14 nights' wear of reverse geometry gas-permeable (GP) contact lenses.
Eighteen subjects (aged 19 to 32 years) with low myopia and astigmatism were fitted with reverse geometry lenses (BE; Capricornia Contact Lens Pty Ltd) for myopic OK, which were worn overnight only for a 14-day period. A separate group of 10 subjects (aged 19 to 32 years) with low astigmatism wore J-Contour conventional GP lenses (Capricornia Contact Lens Pty Ltd) for one night. Corneal topography (Medmont E-300) and total corneal thickness (Holden-Payor optical pachometer) across the horizontal meridian were measured at baseline and approximately 8 to 10 hours after lens removal on days 1, 4, 7, and 14 of overnight OK lens wear and after one night of GP lens wear for the control group. Posterior corneal apical radius of curvature and asphericity (Q) were calculated using an in-house program based on the anterior corneal ellipse curve and corneal thickness.
Myopia reduced from -2.64 +/- 0.99 diopters (mean +/- SD) to -0.39 +/- 0.49 diopters during 14 days of overnight OK lens wear. In the OK lens-wearing eyes, there were no statistically significant changes in posterior corneal apical radius of curvature during 14 days of overnight OK. However, there were statistically significant increases in posterior corneal Q on days 4 and 7. In the conventional GP lens-wearing eyes, there were no statistically significant changes in either posterior corneal apical radius or Q after overnight lens wear.
The researchers concluded that the results of this study support the current hypothesis that the OK refractive effect is achieved primarily through remodeling of the anterior corneal layers, without overall corneal bending.
