The Dry Eye Patient 4-Months After LipiFlow Thermal Pulsation Therapy

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...

Recent Advances is the Surgical Management of Keratoconus

Two of the most significant surgical advances now available for patients suffering from keratoconus who develop contact lens intolerance are Intacs instrastromal corneal ring segments (ICRS) and deep anterior lamellar keratoplasty (DALK) - both provide an alternative to full thickness (or penetrating) keratoplasty or corneal transplantation.  Many folks are going to immediately wonder about corneal collagen cross-linking and I am going to cover that later as “the jury” is still out and as I try to meticulously “connect the...

Observations and Recommendations For Patients with Residual Astigmatism

        Are there mechanisms of which we can take advantage for patients with a high degree of astigmatism including residual, post-surgical astigmatism?  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 has observed that the astigmatic patient becomes particularly symptomatic under poorly lit conditions.  An example of this would include the “drop off” in quality of vision while driving at night under poorly lit...

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...
