The video describes combined surgery of PDEK/ DMEK for a failed penetrating keratoplasty graft in a clear and easy to understand manner. It discusses the order of procedure, changes from the usual strategies when performed in isolation, stages by which the procedure is performed, tips for increasing success, etc. It discusses the advantages and disadvantages of the procedure. It features images, illustrations that help convey information with lucid narration. It also highlights some of the important published literature.
It is useful for young as well as established corneal surgeons, post graduate students, fellows and residents interested in the field, all ophthalmologists, optometrists who are keen to expand their knowledge. They will gain the necessary understanding about the various types of nuances of pre-Descemet’s endothelial keratoplasty for a failed graft.
Introduction
The video explains technique of performing PDEK/DMEK for a failed penetrating keratoplasty with its pros and cons vz repeating a penetrating keratoplasty.

Dr. Jacob has special interest in cutting edge cataract, cornea, glaucoma, complex anterior segment reconstruction and refractive surgery. Her innovations, many of which have won international awards, include anterior segment transplantation, where cornea, sclera, artifical iris, pupil and IOL are transplanted enbloc for anterior staphyloma; suprabrow single stab incision ptosis surgery to enhance postoperative cosmesis; turnaround techniques for false channel dissection during Intacs implantation; glued endo-capsular ring, glued capsular hook and the paper clip capsule stabilizer for subluxated cataracts; stab incision glaucoma surgery (SIGS) as a guarded filtration surgery technique; contact lens assisted crosslinking (CACXL) for safely crosslinking thin keratoconic corneas; endo-illuminator assisted DMEK (E-DMEK), air pump assisted PDEK and host descemetic scaffolding for easier and better surgical results; PrEsbyopic allogenic refractive lenticule (PEARL) inlay for treating presbyopia, corneal allogeneic intrastromal ring segment (CAIRS) for keratoconus and other corneal ectasias; the Jacob modified technique for pre-descemetic DALK as a primary treatment for acute hydrops; sutureless SMILE lenticule assisted resurfacing with interface tattooing for limbal dermoid; white ring sign and the sequential segmental terminal lenticular side cut dissection for safe and effective lenticule extraction in SMILE surgery She has proposed a new classification of descemet’s membrane detachments into rhegmatogenous, tractional, bullous and complex detachments with a suitable treatment algorithm and a new technique of relaxing descemetotomy for tractional descemet’s detachment.
Dr. Jacob’s surgeries and surgical techniques have often been editor’s choice in prestigious international ophthalmic websites (AAO/ ONE network, ISRS, Eyetube etc). She has two popular bimonthly columns, “Complications in Cataract and Refractive Surgery” and “Everything you want to know about” in the prestigious Eurotimes magazine published by ESCRS.
