The LipiView diagnostic instrumentation and LipiFlow Thermal Pulsation Units by TearScience bring an enormous advance for our patients suffering from one of the most common conditions seen in virtually every optometric and ophthalmic practice – including the Duke Eye Center in Durham, NC. This condition is dry eye and the most common cause resulting in dry eye is tear film instability rather than tear production. If you asked me 15 years ago about dryness of the ocular surface, I would relate the problem to aging, hormonal changes, and inadequate tear production. We have witnessed a dramatic shift in our understanding […]
LipiFlow is a thermal pulsation treatment produced by TearScience (Morrisville, NC) invented by Dr. Donald Korb (Boston, MA) that received FDA approval in July 2011 established as safe and effective in the treatment of meibomian gland dysfunction (MGD) and its role leading to evaporative dry eye. This treatment has been available at Duke Eye Center since October 2011 when Duke became the first medical center in the country to offer this treatment on a commercial, non-experimental basis. Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Service at the Duke Eye Center has found […]
Seven Scientific Posters Sponsored by TearScience at ARVO Advance Understanding of Evaporative Dry Eye to Improve Patient Care
TearScience Inc. announced that it sponsored research for seven scientific posters on evaporative dry eye and its technology at ARVO. Subjects reflect new, ongoing research on the disease, TearScience’s technology, and clinical outcomes. The posters cover topics such as how the LipiFlow Thermal Pulsation System can rejuvenate Meibomian gland secretions for up to a year as well as LipiFlow’s efficacy and safety over warm compress therapy for treating Meibomian gland dysfunction. Another demonstrates LipiView Ocular Surface Interferometer’s ability to consistently and accurately measure the thickness of thin film, optically similar to the tear film. Additional research presented increases the general […]
Thanks to Bill and Kathy Hudson and LC Industries for their generosity toward the new state-of-the-art clinical Duke Eye Center in Durham, NC.
From: Victor J. Dzau, M.D., Chancellor for Health Affairs; CEO, DUHS
Subject: Ceremonial Ground-Breaking for New Eye Center Clinical Facility
This morning we held a ground-breaking ceremony for a new, state-of-the-art Duke Eye Center building that will add much-needed clinical examination space and enhance the patient experience.
The ceremony celebrated the team effort that has turned this dream of building a new Eye Center clinical facility into a reality. Thanks to the collaborative efforts of our legion of generous donors, […]
Early results representing my clinical observations and also the subjective response of several patients after treatment have overall led me to believe that the LipiFlow Thermal Pulsation device from TearScience has been one of the most worthwhile additions to my clinical practice in recent years. Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Service at the Duke Eye Center in Durham, NC subspecializes in cataract surgery, corneal transplantation, and laser vision correction (LASIK) and as studied optimizing surgical outcomes for best practices and recognizes that the treatment of symptomatic dry eye syndromes is […]
DALK (Deep Anterior Lamellar Keratoplasty) For Advanced Keratoectasia Caused by Radial Keratotomy (RK)
I am very excited about the recent success I have experienced using a partial thickness or “lamellar” corneal transplant procedure referred to as DALK (deep anterior lamellar keratoplasty) for the treatment of keratoconus, post-LASIK Keratoectasia, and post-RK Keratoectasia. This technique allows retention of the host endothelium which means that donor rejection is essentially eliminated. Since post-RK keratoectasia has been the most challenging, I thought I would tackle that condition and discuss how to correct it. Most patients with post-RK Keratoectasia have multiple and deep incisions and if these incisions perforate Descemet’s membrane, it will be difficult to use the so […]
Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Service at the Duke Eye Center will broadcast into the Royal Hawaiian Eye Meeting Workshop this evening that features Tearscience and the LipiFlow Thermal Pulsation Therapy for patients with symptomatic Evaporative Dry Eye syndrome. As the first University in the United States to actively utilize the TearScience LipiFlow treatment, the Duke Eye Center has been able to offer treatment to a large number of patients seeking relief from their dry eye symptoms. The treatment works by first heating the posterior eye lid in close […]
What Can I Expect From My LipiFlow Thermal Pulsation Therapy for Evaporative Dry Eye at Duke Eye Center?
Having treated 5 patients this afternoon with the LipiFlow Thermal Pulsation device from TearScience for so called “evaporative dry eye” and Meibomian Gland dysfunction, I was asked several times what might I expect based on my recent experience. I obtained permission from several patients to share the following that begins with a link to a general overview of LipiView and LipiFlow followed by several actual treatments and postoperative assessments. Nobody thus far has found any discomfort during the treatment. One patient in the past 3 months said he felt the device got warmer than he expected but not to a […]
It was only a few years ago when optometrists and ophthalmologists almost universally agreed that symptomatic dry eye patients primarily represented deficient tear production and were treated with artificial tears and Restasis. More recently, the evidence is mounting drawing increasing attention toward problems resulting from the meibomian glands lining the eyelids and producing an abnormal or deranged lipid component that is both qualitatively and quantitatively abnormal.
Patients typically have 3 questions after being diagnosed with this abnormality which involves a meticulous examination of the eyelid glands, their express-ability, expressed material, and anatomical and architectural changes of the eyelid. These questions are:
As you contemplate your decision to undergo Laser vision correction or LASIK eye surgery, recognize that it is an extremely complex and personal one. Dr. Alan N. Carlson, Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Service of the Duke Eye Center meets with each patient to discuss the options, risks, limitations, benefits, and likely outcome to set expectations. He prides himself more on carefully screening and often steering a patient away from surgery rather than treating the most patients when it comes to laser vision correction surgery. There are a large number of patients who should […]
