The Diseased Cornea – Research

Various Stem Cell Research projects may hold the promise of finding ways to stimulate corneal endothelial cell regeneration. This is the “holy grail” that could eventually eliminate cornea transplantation in cases of endothelial cell loss. Other research is dedicated to developing better artificial corneas or eventually regenerating entire living corneas for transplantation. – […]

Cornea Transplant Complications

As in any kind of surgery, many different complications can occur. One unique to corneal transplantation is rejection of the donated tissue. Cornea transplants are rejected five to 30 percent of the time and can occur any time after cornea transplantation. The rejected cornea clouds and vision deteriorates. The warning signs of cornea graft rejection are RSVP: […]

Descemet’s Stripping Endothelial Keratoplasty (DSEK), (DMEK), (DMAEK) – selective posterior transplantation

View: 10TV News Report Descemet’s Stripping Endothelial Keratoplasty (DSEK) is a cornea-sparing transplant procedure, brought to Central Ohio in 2006 by Dr Erdey, indicated for patients without corneal scarring and with disease limited to the inner corneal layer (endothelium) such as Fuchs’ Endothelial Dystrophy or Pseudophakic Bullous Keratopathy.

Deep Anterior Lamellar Keratoplasty (DALK) – selective anterior transplantation

Deep Anterior Lamellar Keratoplasty (DALK)  is indicated to correct  conditions which result in corneal thinning, distortion or scarring such as advanced Keratoconus, LASIK or Radial Keratotomy induced corneal thinning,  corneal dystrophy, infection or trauma . DALK is an elegant partial thickness graft that unlike full-thickness corneal transplatation (PK), preserves the TWO inner most layers of the […]

Penetrating Keratoplasty (PK) – full thickness transplantation

Penetrating Keratoplasty (PK) is a traditional full-thickness corneal transplant. This may be required in cases where the cornea is scarred, swollen or excessively thin (Keratoconus). [kml_flashembed movie=”” height=”260″ width=”450″ /] Return of best vision after standard full thickness corneal transplantation may take up to a year or more after the operation. It is dependent on […]

Corneal Transplantation – Variations

Drs. Erdey and Kaswinkel may recommend one of the following surgical variations of corneal transplantation at the time of your consultation: Penetrating Keratoplasty (PK) – Full thickness transplantation Deep Anterior Lamellar Keratoplasty (DALK) –  selective anterior transplantation Descemet’s Stripping Endothelial Keratoplasty (DSEK), (DMEK), (DMAEK)- selective posterior transplantation

Corneal Transplant

Corneal Transplantation may be necessary if your cornea is damaged due to injury or disease. Since there is no artificial substitute for corneal tissue, a human donor cornea is transplanted to restore sight. The Central Ohio Lions Eye Bank typically provides the corneal tissue for our patients. A successful Corneal Transplant requires special, ongoing care and […]

The Normal and Diseased Cornea

The Human Eye is like a telescope in that it contains two lenses to focus light onto the retina. The first “lens” is the cornea which is a transparent, dome-shaped structure covering the front of the eye. It is a powerful refracting surface, accounting for 2/3 of the eye’s focusing ability. Because there are no blood vessels […]
