Big Bubble technique DALK made simple with Fogla Instruments
Dr. Fogla, Indien
(26. September 2008)
Citation: "Big Bubble technique of deep anterior lamellar keratoplasty is an excellent technique of corneal surgery for a variety of corneal disorders wherein the endothelium is healthy such as in keratoconus. My set of instruments have been developed to simplify the learning curve of this technique of surgery, and make it possible to achieve the big bubble more consistently."
Deep Anterior Lamellar Keratoplasty (DALK) for keratoconus, anterior scars
Citation: "Keratoconus was the greatest pain in my life. Contact lenses were the only solution for my vision but with lenses there were limitations in my day-to-day life. I visited many doctors but I was told to continue with lenses till it was bearable. The other solution was total cornea transplant. As per doctors opinion, the success rate was low & in case of failure could lead to blindness. I was asked to be mentally prepared for this worst situation. Luck was on my side & incidentally I came to know about the treatment being done by Dr. Fogla & I immediately contacted him. After hearing his confident tone & the experience quoted, I decided to go for DALK surgery on my right eye. The post surgery days were absolutely painless & no pain killer was required.
Now my life is totally changed. I can see with my operated eye clearly without any aid. The impossible had become
possible just like magic. I am now leading a normal life. ...."

Wikipedia
Keratoconus (section DALK transplants)
Citation: "One way of reducing the risk of rejection is to use a newer technique called a Deep Anterior Lamellar Keratoplasty, referred to as DALK. In a DALK graft, only the outermost epithelium and the main bulk of the cornea, the stroma, are replaced; the patient's rearmost endothelium layer is retained, giving some additional structural integrity to the post-graft cornea.[45] Because a graft rejection usually begins in the endothelium,[citation needed] the chance of a rejection episode is greatly reduced. Furthermore, it is possible to transplant tissue from a donor which has been freeze-dried. The freeze-drying process ensures that this tissue is dead, so there is no chance of a rejection.[45]
Some surgeons prefer to remove the donor epithelium, others leave the donor's cells in place. Removing it can cause a slight improvement in overall vision, but a corresponding increase in visual recovery time."

Zitat: "Unter der Ägide von Dr. Melles wurden in den letzten Jahren innovative Operationstechniken wie zum Beispiel DALK, DSEK und DMEK entwickelt, vor allem zur Behandlung des Keratokonus und der Fuchs’schen Endotheldystophie. Die angewandten Behandlungsmethoden sind „state of the art“ und haben in der Ophthalmologie neue Perspektiven eröffnet: So konnte die Zeit der Rekonvaleszenz auf wenige Wochen, statt bisher 1½ bis 2 Jahre reduziert werden. Die durch die OP erlangte Sehfähigkeit konnte in vielen Fällen auf 0.8 und mehr, statt bisher 0.5 erhöht werden. ..."
