This weeks newsletter will focus on the exceptional webinar entitled: “Management of the Scleral Lens Ocular Surface Disease Patient" presented by Dr. Karen Carrasquillo. This topic is a very important one today. The SCOPE study (1) found that one in six scleral lenses being fit today are patients exhibiting some form of ocular surface disease. Certainly it can be argued that this percentage should be higher.
Dr. Carrasquillo received her doctor of philosophy degree in chemistry and that was followed by the completion of a
post-doctoral research fellowship in ophthalmology at Massachusetts Eye and Ear/Harvard Medical School. She received her doctor of optometry degree, followed by a residency specializing in cornea and specialty contact lenses, at the New England College of Optometry.

It was at that time – some 15 years ago – when she literally jumped on my radar as she was under the tutelage of Dr. Marjorie Rah who at that time – along with Dr. Jeff Walline – represented perhaps the 2 leading clinical researchers in the world on CL wear in young people.
She is currently VP of clinical and professional affairs at BostonSight(R) and an adjunct clinical professor at the New England College of Optometry and the School of Optometry, MCPHS University. She has been a true innovator in modern scleral contact lens design and their applications, including ocular surface disease.

"Management of the Scleral Lens Ocular Surface Disease Patient"

Karen Carrasquillo OD, PhD, FBCLA, FAAO, FSLS

In this presentation, archived under the “webinar” tab on, Dr. Carrasquillo emphasizes that – when managing Ocular Surface Disease (OSD) with scleral lenses - there are some non-optional essentials including:

1)   A thorough understanding of the disease

2)   Willingness to co-manage with other specialists

3)   Understanding of risk factors that can lead to complications

4)   See the BIG picture – never forget your clinical training
She then presented some very interesting clinical cases pertaining to Sjogrens Syndrome, Graft Versus Host Disease, Atopic Disease, and Neurotrophic Keratopathy.

She gave a brief description of each of these conditions with treatment followed by a case. The case would present relevant management pearls with scleral lenses and adjunct pharmaceutical therapy, as well as problem-solving and relevant literature. In addition, it was also an interactive presentation as the audience was polled to provide their opinion on case management and treatment options. What makes this as good a clinical presentation on this important topic as you will ever watch is a combination of the clinical pearl/”Big Picture” format combined with outstanding graphics of diseased eyes, scleral lens applications, and management nomograms.

Scleral Lenses and Ocular Surface Disease

The GP Lens Institute has several resources to assist with these patients. In addition to Dr. Carrasquillo’s webinar and other archived webinars in the “Scleral” category under the “Education” followed by “By Lens Type” tabs on the home page, we have a consumer brochure available on scleral lenses, and a Scleral Lens Care Tips, Application and Removal Card laminated card, both available under the “Resources” category. An invaluable resource - in cooperation with the Scleral Lens Education Society - is the “Scleral Lens Troubleshooting FAQs” downloadable booklet from the home page which includes management of ocular surface disease with scleral lenses.
