As you will note from this week’s abstract, there continues to be a thought that inflammation is a part of contact lens wear—even in normal, asymptomatic contact lens wearers. This thought is not novel or new, but we don’t seem to really fully understand this notion. What are your thoughts? Do you think contact lens wear is associated with a low grade/subclinical inflammatory response? Please send any thoughts you have to email@example.com.

Heavy Protein Deposits on Scleral Lens Alon Brondwine, Optometrist BSc, MHA, Rishon Le Zion, Israel
A 40-year-old male with keratoconus post-penetrating keratoplasty and fitted 18 month ago with a 16.5mm mini scleral lens complained of decreased visual acutity. It wasn't hard to notice that the lens was covered with protein. The patient admitted to being busy recently and not being compliant with his cleaning regimen; he was using a daily cleaner for soft contact lenses. After we polished and cleaned the lens, he was able to achieve 20/30 vision with this lens. This case emphasizes that, even for established contact lens wearers, compliance may still be an issue and follow-up must be routine

Prescribing Trends in Contact Lenses 2002 to 2014 – Yes, Our Habits Have Changed
A recent publication reviewed the results of surveys of contact lens prescribing trends in the United States that were conducted on an annual basis between 2002 and 2014.1
Over the 13-year survey period, 1,650 survey forms were received from U.S. practitioners representing details of 7,702 contact lens fits. The mean (±SD) age of lens wearers was 33.6 (±15.2) years, of whom 65.2% were female. Rigid lens new fits decreased from 13.0% in 2002 to 9.4% in 2014. Across this period, silicone hydrogels have replaced mid water contact lens hydrogels as the soft lens material of choice. Toric lenses represented about 25% to 30% of all soft lens fits. Multifocal soft lenses are generally preferred to monovision. Daily disposable lens fits have recently increased, and, in 2014, they represented 27.1% of all soft lens fits. Most lenses are prescribed on one- to two-weekly or monthly lens replacement regimens. Extended wear remains a minority lens wearing modality. The vast majority of those wearing reusable lenses use multipurpose lens care solutions. Lenses are mostly worn seven days a week.
So, we can see from the results of these surveys that our contact lens prescribing trends have surely evolved in the United States following the entry into the new millennium. We see a variety of trends including a progressive decrease in the rate of prescribing corneal GP lenses, movement from hydrogel soft lenses to silicone hydrogels, an increase in the rate of prescribing toric lenses that more appropriately approximates the prevalence of astigmatism in the population, multifocals have become the contact lens vision correction modality of choice over monovision, and a strong trend toward the prescribing of daily disposable lenses. Interestingly enough, the prescribing of contact lenses for continuous wear has stilled remained uncommon. We have realized that we still have quite a way to go technologically to meet the goal of safe and effective continuous wear and that there is much more than oxygen transmission when it comes to the solution to this problem.

OCULAR SURFACE UPDATE Katherine M. Mastrota, MS, OD, FAAO
What a Great Idea
Colleagues who know me know that Demodex is a favorite topic of mine. Rotating lashes within the follicle is an easy way to find them.1 Once isolated, the clinician can then decide what to do, or not do, about them. Each practitioner has his or her own way of “translating” the diagnosis to the patient. Some treat Demodex without elaboration of the mite’s existence to the patient; others prefer the enhanced compliance in therapy that a “show-and-tell” diagnosis garners: the mite’s clawed crawling little legs is a very powerful image.
In a new short 2015 article by Vahedi and colleagues, the authors describe a method to use smartphone video to document motility of Demodex folliculorum in human eyelashes. In contrast to static images, the availability of portable, high-quality video offered by smartphones (of video captured through microscope oculars) provides the opportunity to integrate biopsy results immediately into education, discussion of management, counseling, and offers a salient visual image with which patients may engage in discussion. With increasing use of electronic medical records, these may be stored in a database to be associated with patient files. The authors suggest that the use of smartphone video in documenting the motility of organisms may prove to be beneficial in a variety of medical fields.2 Try it.

Conjunctival Goblet Cell Function: Effect of Contact Lens Wear and Cytokines
This review focuses on conjunctival goblet cells and their essential function in the maintenance of eye health. The main function of goblet cells is to produce and secrete mucins that lubricate the ocular surface. An excess or a defect in those mucins leads to several alterations that makes goblet cells central players in maintaining the proper mucin balance and ensuring the correct function of ocular surface tissues. A typical pathology that occurs with mucus deficiency is dry eye disease, whereas the classical example of mucus hyperproduction is allergic conjunctivitis. In this review, we analyze how goblet cell number and function can be altered in these diseases and in contact lens wearers. The study found that most published studies focused exclusively on the goblet cell number. However, recent advances have demonstrated that, along with mucin secretion, goblet cells are also able to secrete cytokines and respond to them. The authors describe the effect of different cytokines on goblet cell proliferation and secretion. They concluded that it is important to further explore the effect of contact lens wear and cytokines on conjunctival goblet cell function.
