Also known as Anwar Big bubble technique, deep anterior lamellar Keratoplasty (DALK) is a surgical procedure that replaces the cornea while preserving the thin posterior membrane.
It is an alternative to full thickness Penetrating Keratoplasty (PKP) and is indicated for management of advanced keratoconus , corneal scarring, post LASIK ectasia, endothelium sparring corneal dystrophies and degenerations.
The advantages of DALK include reduced rejection rate, reduced risk of late endothelial cell failure, quicker stabilization of the wound and earlier return to unrestricted physical activity. A shorter course of topical steroids (anti rejection drops) after DALK means faster healing and less risk for steroid induced glaucoma and cataracts.
If the thin posterior membrane ruptures during the surgery, the procedure is converted to a full thickness transplant (penetrating keratoplasty).
“Seeing Dr. Sajja was very easy and efficient. He was very thorough and professional. He was also very honest in what he felt needed to be done. He also had a very good bedside manner and was caring, nothing was painful at all. The surgery was a quick procedure and I was in excellent care. I was amazed that Dr. Sajja himself called me two days after surgery to check-up on me!”
“Dr. Milan Patel is an excellent, caring physician. From the initial exam through cataract surgery he was very patient with explaining the surgery and recovery process. I had both eyes replaced with new lenses and felt extremely comfortable through both procedures. I highly, highly recommend him!”
“I was scared of having my cataracts removed, but the doctor and all of the staff made me most comfortable. There was no pain & the recovery was short. I would recommend Dr. Desai to anyone who needs surgery. And the people who work there are just wonderful”
