Manual DALK techniques for keratoconus | Eversight webinar recap

By Michael Szkarlat, Partner Development Director

Nov. 17, 2022 — We were joined by Dr. Uri Soiberman of the Johns Hopkins Wilmer Eye Institute for our November 2022 webinar. Dr. Soiberman offered his expertise on manual techniques for deep anterior lamellar keratoplasty (DALK) surgery in patients with keratoconus. This included his latest experience with the groove and peel technique which was recently published in Cornea. 

The webinar begins with a discussion of keratoconus disease incidence, etiology and the impact on patients, as well as a brief overview of the current treatments and some of their limitations. Dr. Soiberman reviews some of the general advantages of DALK over conventional penetrating keratoplasty (PKP) along with some literature on the topic. He discusses some of the current techniques for performing DALK, including one of the most common—the “big bubble” technique—which was described by Anwar and Teichman in 2002. Highlighting some of the challenges and limitations of this technique, he introduces various other techniques described over the years for manual, or non-big bubble, DALK. 

Dr. Soiberman dives into a series of cases using techniques including big bubble, manual dissection, the Melles technique, and finally several cases of the groove and peel technique. This leads to a detailed discussion of the groove and peel technique, including approach, instrumentation, surgical pearls and principles behind it. The webinar concludes with a lively Q&A discussion.
