Summary
Small Incision Lenticule Extraction (SMILE) is a safe myopia correction method, but intraoperative complications like incision tears and lost vacuum can occur. Most issues are linked to surgeon experience and the learning curve for this refractive surgery technique.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Small Incision Lenticule Extraction (SMILE) is a popular refractive surgery for myopia and myopic astigmatism.
- Understanding intraoperative complications is crucial for patient safety and surgical technique refinement.
Purpose of the Study:
- To document and analyze intraoperative complications during SMILE procedures.
- To outline management strategies for these surgical events.
Main Methods:
- Retrospective analysis of consecutive interventional cases.
- Data collection on complication types and their resolution during SMILE surgery.
Main Results:
- 282 eyes from 141 patients were analyzed.
- Complications included incision tears (9.57%), wound bleeding (7.45%), epithelial defects (5.32%), and lost vacuum (6.38%).
- Less frequent issues were treatment decentration, incomplete bubble separation, lenticule adherence, and cap perforation.
Conclusions:
- SMILE offers predictable and safe outcomes for myopia correction.
- Intraoperative complications are often associated with the surgeon's learning curve.
- Further research with larger cohorts is needed to standardize complication management.

1.8K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

01:24Hemodialysis II: Procedure and Complications
779
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
