Anatomy and Physiology
An abundance of these can be found in the macula... or behind the counter of an ice cream shop
What are cones?
This method of corneal transplant is a common treatment for Fuchs' Dystrophy, and may or may not include a partial layer of stroma
What is EK or endothelial keratoplasty?
This layer of the cornea is made up of highly-organized collagen fibers. Displacement caused by edema causes the cornea to become opaque
What is the stroma?
This method of transplant is indicated for issues affecting only the anterior of the cornea, such as partial-thickness scarring
What is ALK or anterior lamellar keratoplasty?
An enzymatic pump system in the endothelium uses these two elements to prevent corneal edema by creating an ion gradient
What are sodium and potassium?
This method of transplant requires a full-thickness cornea. It can be used to remove keratoconus, corneal perforations, or congenital opacities, among other things
What is PK or penetrating keratoplasty?
This structure posterior to the cornea is responsible for changing the shape of the lens and creating both the aqueous humor and vitreous humor
What is the ciliary body?
This relatively rare procedure involves the placement of an artificial cornea, for when penetrating keratoplasty is repeatedly unsuccessful. Donor tissue is required to hold the device in place
What is K-Pro or keratoprosthesis?
When endothelial damage occurs, surrounding cells alter their shape to fill in the gap in this process... like birds do to reach warmer climates
What is cell migration?
This medical device resembling a common office supply item assists in treating retinal detachment by altering the shape of the eye
What is a scleral buckle?
