Postoperative Corneal Complications in Small Incision Lenticule Extraction: Long-Term Study
Journal of Refractive Surgery (Thorofare, N.J. : 1995)
|March 12, 2019
Summary
Small Incision Lenticule Extraction (SMILE) can cause corneal complications in 6.8% of patients, though most resolve with treatment. Visual recovery may be temporarily affected but typically improves over time.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Small Incision Lenticule Extraction (SMILE) is a popular refractive surgical procedure.
- Understanding potential postoperative complications is crucial for patient management and surgical outcomes.
Purpose of the Study:
- To determine the incidence of corneal complications following SMILE surgery.
- To evaluate the clinical outcomes and visual recovery associated with these complications.
Main Methods:
- Retrospective cohort study of 3,223 patients (6,373 eyes) undergoing SMILE for myopia or myopic astigmatism.
- Systematic recording of all postoperative corneal complications.
- Scheduled follow-up visits at standard intervals up to 12 months post-surgery.
Main Results:
- A total of 6.8% of eyes (432/6,373) experienced at least one corneal complication.
- Common complications included punctate epithelial erosions (3.26%) and diffuse lamellar keratitis (2.17%).
- Most complications had minimal impact on visual acuity, with rapid recovery observed in the majority of cases.
Conclusions:
- SMILE surgery is associated with a range of corneal complications, with a low overall incidence.
- While some complications may transiently impact visual recovery, prompt and appropriate treatment generally leads to favorable outcomes.
- The study highlights the safety and efficacy of SMILE with effective management of potential adverse events.

Diabetes: Symptoms, Diagnosis, and Complications

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...

Long-term Depression
33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Hemodialysis II: Procedure and Complications
763
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,...
