Editor's Commentary - Jason J. Nichols, OD, MPH, PhD, FAAO

I have many good colleagues who feel quite strongly about diagnostic fitting with nearly all GP contact lens fits. However, I also realize that there are many practitioners who usually go the empirical route. I think it's important for students and practitioners to learn and understand the diagnostic fitting process first, but ultimately I feel it is important to do what's right for the patient and the specific situation. GP labs have excellent support staff who can always help you along the way.

Blanchard Contact Lens Launches Professional Development Center

The Blanchard Contact Lens Research and Professional Development Center in Manchester, New Hampshire hosted its inaugural session featuring the msd Mini Scleral Design in June.

The Center was designed to provide eye care practitioners up-to-the-minute fitting techniques in a small group setting. Hands-on, practical learning, joined with state-of-the-art digital imaging equipment, provided attendees with a high quality learning experience. The session was limited to eight attendees in order to maintain the quality of the session and hands-on experience.

Session agenda included: a tour of the Blanchard laboratory and lens production; in depth presentation of the msd lens with Stephen Byrnes, OD, who has fit well over 100 patients with the msd lens; a hands-on workshop, learning and practicing techniques for applying and removing lenses in the wet lab with Dr. Byrnes; and active participation in a series of patient fits with Dr. Byrnes.

Blanchard plans to host additional sessions in August, September, and October. Those wishing to attend should contact their Blanchard Sales Representative to discuss availability. For more information visit www.blanchardlab.com or call 800 367-4009.

RESEARCH REVIEW
Loretta B. Szczotka-Flynn, OD, PhD, MS, FAAO

Pregnancy and Keratoconus

There has long been the thought that hormonal changes that accompany pregnancy can influence the progression (or occurrence) of keratoconus. However, there are no good case reports in the literature to support this. I have at least one patient that fits this category.

A new paper reports a case series of four patients that showed progression of keratoconus during pregnancy, excluding patients with accompanying systemic and ocular diseases associated with keratoconus, uncontrolled atopic disease, and eye rubbing. Bilgihan and colleagues in Turkey documented seven eyes of four pregnant women that showed changes in refraction, corneal topography, and rigid gas-permeable lens fitting pattern during pregnancy.

The mean age of patients was 29.3 years. Mean increase in spherical equivalent refraction and simulated keratometry values were 1.4 ± 1.1 and 1.1 ± 0.8 diopters, respectively. In eyes wearing rigid gas-permeable lenses, increase in corneal apical touch and decrease in the base curve radius of the best-fitting contact lens were observed. This is probably the first study showing pregnancy-induced keratoconus progression in patients with no other accompanying disease or risk factor for keratoconus.

A New Way to Keep Lenses Wet

In this column, I have discussed various methods that have been developed to improve comfort of contact lens materials. These include wetting agents bound within the lens matrix, wetting agents in the blisterpack, and polymer chemistry that increases water binding properties. In addition, new lens care products have been developed that improve surface wettability and deposit resistance. There are also numerous rewetting drops that can temporarily improve surface wetting during lens wear.

Researchers at Auburn University have published a paper on a silicone hydrogel lens they have modified to release a wetting agent over the course of several days. The paper describes a molecular imprinting process that can be modified to allow the release of hydroxypropyl methylcellulose for up to 60 days while the lens is worn on a continuous wear basis. They report good optical and mechanical properties of the modified lens. This may be a future way to improve long-term comfort, and possibly even as a drug delivery device for chronic eye conditions. We look forward to more developments like this in the quest for comfort.

A Histopathological Study of Bulbar Conjunctival Flaps Occurring in Two Contact Lens Wearers

Researchers wanted to study the histopathology of paralimbal bulbar conjunctival flaps occurring secondary to soft contact lens wear.

Slit-lamp biomicroscopy using sodium fluorescein, cobalt blue light, and a Wratten filter was used to observe the presence, location, and dimensions of bulbar conjunctival flaps presenting in a cohort of contact lens wearers. Two subjects who exhibited such flaps agreed to undergo conjunctival biopsy. Tissue samples, obtained from the region of the flap, and an adjacent unaffected area were processed by standard histopathological methods.

In the first subject, analysis of the flap tissue showed even collagen distribution and overall normal histology. The flap of the second subject displayed a mild focal increase in collagen and mild degeneration of collagen, but no increase in elastic tissue. Conjunctival epithelium was normal in both cases.

The authors concluded that in these two subjects conjunctival flap tissue either was normal or showed only minimal abnormality. There is insufficient evidence for significant pathological change on the time scale of this study.
