Editor's Commentary - Jason J. Nichols, OD, MPH, PhD, FAAO
I often hear practitioners state that they feel that the true frequency of keratoconus in the population is under-estimated by the epidemiological studies of the disease. This certainly may be true, but very likely depends on the definition of the disease used to diagnose its frequency/prevalence in the population. That said, the last decade has shown a tremendous increase in our scientific knowledge base on keratoconus, and other corneal diseases.

Telescopic Contact Lens/Smart Glasses Prototype for AMD and Low Vision in the News

Researchers recently unveiled a new prototype of a telescopic contact lens which works in combination with smart glasses. The glasses allow the wearer to control the zoom feature of the contact lens with eye winks, and are designed to recognize winks and ignore blinks.

The scleral contact lens is 1.55 mm thick and has a very thin reflective telescope inside. Tiny mirrors reflect the light, expanding and magnifying viewed objects so what you see is similar to what you can see through low magnification binoculars. The telescopic contact lens magnifies 2.8 times. Since the first prototype in 2013, the developers have been fine tuning the lens material so it can be worn comfortably over longer periods and making the lens more breathable. The developers are still working on improving oxygen permeability and image quality.

This is still research, but developers are hopeful it will eventually become a real option for people with AMD. Here is a link to one of many recent stories on the lens/smart glasses combo:

Silicone Hydrogel Lens on Post PK Cornea
Jaime Ibanez, OD, Villavicencio, Colombia

This aphakic patient with a post PK cornea and a 15mm, +16.50 silicone hydrogel contact lens was fitted three months after the surgical procedure. With the lens the patient restored his VA to obtain binocularity. A key issue was the alignment of the optic center of the lens with the visual axis of the eye; the centration was achived by selecting the appropriate sagittal height of the contact lens.

We thank Dr. Ibanez for this image and we welcome photo submissions from our other readers! It is easy to submit a photo for consideration for publishing in Contact Lenses Today. Simply visit to upload your image. Please include an explanation of the photo and your full name, degree or title and city/state/country.

The Effect of Contact Lens Hygiene Behavior on Lens Case Contamination

One of the most overlooked components of good contact lens care has been the contact lens case.1,2 It is well-documented that microbial contamination of a contact lens case can lead to lens-related adverse events.3 A recent paper by Wu, Willcox, and Stapleton4 looked at the association between the levels of lens case contamination and lens wearers’ hygiene habits.

The authors surveyed 119 contact lens wearers and tested their cases. Sixty-six percent of cases were contaminated. The authors discovered that the factors that can reduce lens case contamination are:

1. Washing hands with soap and water
2. Air drying lens cases
3. Using the lens case supplied with the manufacturer’s solution.

Poor (or lack of) hand-washing5 has long been implicated in contact-lens related keratitis and it makes sense that it affects the case as well. It never ceases to amaze me why some patients do not wash their hands prior to handling their lenses. Also of interest is the third point: patients should use the case that was provided with their particular multi-purpose solution. It is what is most compatible with that solution, and together they comprise a care system.

Master Movers

Most of us have an understanding of what orthokeratology is, but the data reads strongly that most of us do no ortho-K, few of us do some, and a couple do A LOT. Prior to buying my practices, I had the pleasure of working for several years in Seattle with an ortho-k guru. This doctor has created an ortho-k practice that brings patients in from all over. He does not shy away from a challenge, but proceeds cautiously in complicated situations. I recall one patient who had a -10.00 refractive error that we took on. Although the patient’s refractive error wore off slightly throughout the day and she had a residual -1.00 by the end of the day, this patient was able to SEE without contact lenses and glasses. She was happy to carry glasses with her for the needed times of vision correction.

Orthokeratologists are master corneal movers. They know how to mold and bend the cornea in order to create optimal refractive correction. Through the use of lenses they can correct for astigmatism, hyperopia, presbyopia, and of course myopia. If you want to start molding and moving corneas, I would encourage you to reach out to a colleague or your laboratory for help. As someone who sees a couple of ortho-K patients a week, I am proud to say that moving the cornea is rewarding for you and your patients.

Publication Analysis of the Contact Lens Field: What Are the Current Topics of Interest?
The purpose of this study was to determine the main current research interests of scientists working in the contact lens field.

All articles published in the 2011 issues of all journals included in the Journal Citation Reports subject category Ophthalmology were inspected to expose those papers related to the contact lens field. Information regarding source journal was obtained and authorship details were recorded to determine the top most prolific authors, institutions and countries. A comprehensive list of key words was compiled to generate a two-dimensional term map in which the frequency of occurrence of a particular term is defined by label size and the distance between two terms is an indication of the relatedness of these terms, based on their co-occurrences within groups of key words. Clusters of related terms were also identified.

Visual examination of all articles uncovered a total of 156 papers, published in 28 different journals. Contact Lens & Anterior Eye, Eye & Contact Lens and Optometry and Vision Science had 27 articles each. The most prolific authors and institutions revealed the predominance of countries with long research tradition in the contact lens field. Ten different word clusters or areas of interest were identified, including both traditional, yet unresolved issues (e.g., comfort or dry eye), and the latest research efforts (e.g., myopia control).

The authors concluded that these findings, which revealed contact lenses to be a fertile area of research, may be of relevance to new researchers as well as to those interested in exploring the latest research trends in this scientific discipline.
