Summary
Inseparable corneal lamellae during Descemet stripping automated endothelial keratoplasty (DSAEK) preparation can be caused by cutting errors or premature separation. Careful donor cornea inspection can prevent issues and allow successful DSAEK.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Tissue Engineering
Background:
- Descemet stripping automated endothelial keratoplasty (DSAEK) is a common procedure for treating endothelial dysfunction.
- Proper preparation of donor corneal tissue is crucial for successful DSAEK outcomes.
Observation:
- Six cases of apparently inseparable corneal lamellae during DSAEK tissue preparation were reported.
- These cases involved issues during intraoperative handling and eye bank precut tissue.
Findings:
- Inadequate lamellar cuts or premature separation of corneal layers were identified as primary causes.
- Surgery was aborted in four cases due to inseparable lamellae; one case involved successful transplantation after identifying a free anterior cap.
Implications:
- Thorough pre-operative inspection of donor corneas under magnification is essential to identify potential issues.
- Understanding these complications can improve DSAEK tissue preparation protocols and surgical success rates.

Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
Tissue Transplantation
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications
Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
