As you noted in our January 2015 issue of Contact Lens Spectrum, we designated beauty enhancing contact lenses to be the contact lens event of 2014 (http://www.clspectrum.com/articleviewer.aspx?articleID=112120). For a variety of reasons, the "cosmetic" contact lens segment of the market has remained stagnant for many years. We anticipate that the new technologies in this space will allow for some increased enthusiasm and expansion of this market segment. We would like to get your thoughts on this. Please let us know how you see the cosmetic category fitting into your contact lens practice in the years to come by emailing us at firstname.lastname@example.org.

Quality of Life Issues with Contact Lens Treatments for Keratoconusâ€¦Where Do We Start and Where Are We Going?
Our approach to the contact lens management of keratoconus patients often focuses squarely on visual acuity outcomes. The mainstay of such management has been achieved typically with the use of corneal rigid gas permeable contact lenses due to their ability to mask significant corneal irregularity and provide dramatically improved visual acuity when compared to spectacles. However we need to remain cognizant of the impact our treatments have on our keratoconic patientâ€™s quality of life.
A study was recently conducted that evaluated the impact of rigid gas-permeable (RGP) contact lenses on vision-related quality of life (VR-QOL) in keratoconic patients with different grades of severity.1 Forty-six patients with bilateral keratoconus were divided into three groups according to the average of the steep keratometry (K) readings in the two eyes of each patient. Main outcome measures included binocular visual acuity (VA), lens wearing time, the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), foreign body (FB) sensation, comfort and overall satisfaction. Results found that patients with severe keratoconus showed significantly reduced wearing time compared with the other two groups (4.8 Â± 2.5 hours per day). Regarding the subjective criteria, there was no significant difference on NEI-VFQ-25 scores, foreign body sensation, comfort and overall satisfaction between mild and moderate keratoconus groups but scores in the group with severe keratoconus were significantly lower than the other two groups. Binocular VA strongly correlated with NEI-VFQ-25 scores; however, NEI-VFQ-25 scores had no significant correlations with different disease severities.
The researchers concluded that appropriate correction with RGP lenses contributes to good vision related quality of life for keratoconic patients; however, as the disease progresses to a steep keratometric value of more than 52 diopters (6.50 mm), RGP lenses did not guarantee a relatively good VR-QOL and other subjective quality of life measures such as comfort and overall satisfaction with CLs diminish significantly in more advanced disease. They suggested that alternative contact lens options with new designs might bring better life quality for patients with severe keratoconus.
Contemporary contact lens management of keratoconus is no longer limited to the use of corneal rigid gas permeable lenses. Alternatives today also include specialty keratoconus soft lenses, vaulting hybrid lenses, scleral GP lenses as well as tandem/piggyback lens systems. The advantages of these other alternatives to corneal GPs includes significant improvement in lens comfort, minimization of lens to cornea direct contact, improved lens positioning and fit stability all the while still maintaining excellent visual improvement. The net outcome of the utilization of the various contact lens alternatives can be a significant improvement in our patientâ€™s quality of life. The question now is â€œwhere do we start when it comes to contact lens options for keratoconus?â€ If faced with a newly diagnosed case of keratoconus should we initially attempt corneal gas permeable lens fitting or should we consider the alternatives that we now have access to? Unfortunately other elements can come into play such as expense differences and whether or not third party coverage for medically necessary contact lenses will allow us to go straight towards the alternatives to corneal GPs. We are already seeing medically necessary CL plans being introduced that tie reimbursement and lens designs options to the degree of severity of keratoconus. I strongly feel that the decisions pertaining to the most appropriate CL option for our patients should always be made between the doctor and patient. OK, call me old school!

Makeup and Eyelash Structure
One of my colleagues who is as interested in Demodex as I am, recently asked me how the use of makeup impacted, or not, populations of Demodex in and around the lid margin and how. Frankly, I donâ€™t know. In researching it, I did pick up an interesting tidbit of information:
A recent Japanese study investigated how eye makeup affects the eyelash structure. The internal structure of eyelashes was observed with a scanning X-ray microscopic tomography system from 36 Japanese women aged 20-70 years and whose use of eye makeup differed.1 Reconstructed cross-sectional images showed that the structure of the eyelash closely resembled that of scalp hair. The researchers noted that eyelash structure is changed by use of eye makeup. There was a positive correlation between the frequency of mascara use and the degree of cracking in the lash cuticle (the hard 5-12 layer deep surface shingle-like layer of dead, overlapping cells which gives the hair shaft strength). Positive correlation was also found between the frequency of mascara use and the porosity of the cortex (the cortex of the hair shaft is located between the hair cuticle and the innermost medulla and is the thickest hair layer; it contains most of the hairâ€™s pigment, giving the hair its color).
I wonder if/how lashes, perhaps compromised by mascara, impact Demodex populations. Would they be more or less â€œcomfortableâ€ in a sub-par hair environment? Does the mascara impact the eyelashes only, or does it affect the follicle that the hair is generated and resides in? What about the hair stem cell environment? So many questionsâ€¦

Seasonal, Geographic, and Antimicrobial Resistance Patterns in Microbial Keratitis: 4-Year Experience in Eastern Pennsylvania
The aim of this study was to review the demographics, causative organisms, seasonal and geographic variation, and antimicrobial resistance patterns of microbial keratitis at the researchers' institution over a 4-year period.
Electronic medical records of all patients with microbial keratitis who underwent corneal culturing at a single institution in eastern Pennsylvania between January 1, 2009 and December 31, 2012 were reviewed.
A total of 311 patients representing 323 instances of infectious keratitis were analyzed. The most frequently implicated organisms in contact lens-related infections were Pseudomonas aeruginosa for bacteria and Fusarium species for fungus, compared with Staphylococcus aureus and Candida species in non-contact lens-associated bacterial infections. Bacterial keratitis occurred most frequently in spring and least frequently in winter (P = 0.024). Patients who live in large fringe metro (suburban) areas accounted for the highest proportion of infectious keratitis cases.P. aeruginosa and methicillin-sensitive S. aureus isolates were highly susceptible to fluoroquinolones, whereas 32% of coagulase-negative staphylococcus isolates tested were resistant to moxifloxacin and gatifloxacin, and all methicillin-resistant S. aureus organisms tested were resistant to these two fluoroquinolones. No organisms tested were resistant to tobramycin, gentamicin, or vancomycin. No fungal infections tested were resistant to voriconazole.
The authors concluded that most infectious keratitis occurred in non-winter months and in patients from suburban counties. Although fluoroquinolones were effective against the most common bacteria, staphylococcal species exhibited a high rate of resistance, representing a therapeutic challenge given the increasing use of fluoroquinolones as first-line monotherapy. No organisms tested were resistant to tobramycin, gentamicin, vancomycin, or voriconazole.
