LAMELLAR KERATOPLASTY Meaning and
Definition
-
Lamellar keratoplasty is a surgical procedure performed to correct corneal disorders by replacing the damaged or diseased layers of the cornea with healthy tissue. The word "lamellar" refers to the partial thickness replacement of the cornea, where only specific layers are removed and replaced, as opposed to a full-thickness transplant.
The cornea is the clear, dome-shaped tissue covering the front of the eye. It plays a crucial role in focusing light onto the retina for clear vision. However, various conditions such as corneal scarring, degeneration, or irregularities can disrupt the cornea's normal structure and function, leading to vision problems.
During lamellar keratoplasty, a skilled ophthalmic surgeon carefully removes the affected layers of the cornea, leaving the healthy underlying layers intact. This targeted removal allows for the preservation of stable tissue, reducing the risk of complications associated with a full-thickness corneal transplant.
Once the damaged layers are removed, the surgeon places healthy corneal tissue from a donor or synthetic material onto the affected area. The transplanted tissue is meticulously sutured or adhered to the recipient's cornea, ensuring proper alignment and integration.
Lamellar keratoplasty can be performed through different techniques, including anterior lamellar keratoplasty (ALK) or posterior lamellar keratoplasty (PLK), depending on the specific layers of the cornea that need to be treated.
This surgical procedure offers several advantages over traditional full-thickness corneal transplantation, such as faster visual recovery, lower risk of graft rejection, and reduced need for immunosuppressive medications. However, the suitability of lamellar keratoplasty depends on individual patient factors and the extent of corneal damage,

Etymology of LAMELLAR KERATOPLASTY
The word "lamellar" comes from the Latin word "lamella", meaning "thin plate" or "scale". It is derived from the Latin word "lamina", which means "thin sheet".
The word "keratoplasty" is derived from two Greek words. "Kerato-" comes from the Greek word "keras", meaning "horn" or "cornea". "Plasty" comes from the Greek word "plassein", meaning "to mold" or "to shape".
Therefore, the term "lamellar keratoplasty" refers to a surgical procedure that involves shaping or molding thin plates or layers of the cornea.
