Keratoplasty /Cornea Transplant Surgery in Guwahati

There are a number of different types of corneal transplant surgeries, each with its own benefits and drawbacks. Penetrating keratoplasty (PK), Descemet’s stripping endothelial keratoplasty (DSEK/ DSAEK), Descemet’s membrane endothelial keratoplasty (DMEK), deep anterior lamellar keratoplasty (DALK), and superficial anterior lamellar keratoplasty (SALK) are all types of keratectomy surgery. 

In PK, the surgeon removes the damaged layer of the cornea using a blade or scalpel and replaces it with an artificial implant. The benefit of this surgery is that it is relatively easy to perform and results in a good visual outcome in most cases. 

DSEK/ DSAEK is a more advanced type of PK surgery that uses a laser to cut through the damaged layer of the cornea. This procedure results in a better quality artificial Cornea Transplant because there is less chance for scarring and better control over the thickness of the implant. DMEK is similar to DSEK/ DSAEK, but instead of replacing the entire damaged layer of the cornea, it only removes parts of it. This procedure results in a thinner but stronger artificial Cornea Transplant and is usually preferred when there are severe vision problems due to limited vision in one or both eyes. 

DALK is a more recent type of PK surgery that uses a laser to remove the outer layer of the cornea, leaving the inner layer intact. This results in a stronger and more durable artificial cornea transplant. SALK is another newer type of surgery that removes only the very surface of the cornea, resulting in a thinner but still strong artificial transplant.
