Summary
Spectacle non-tolerance affects 2.1% of patients, often due to refraction errors. Understanding these causes is crucial for improving vision care and patient satisfaction.
Area of Science:
- Ophthalmology
- Optometry
- Public Health
Background:
- Spectacle non-tolerance presents significant challenges for patients and eye care practitioners.
- Addressing spectacle non-tolerance is vital to prevent vision impairment and maintain practice reputation.
Purpose of the Study:
- To systematically review the prevalence and identify the primary causes of spectacle non-tolerance in clinical practice.
Main Methods:
- A systematic review of quantitative studies published in English up to July 2020.
- Searches conducted in PubMed, Scopus, and Web of Science databases.
- Quality assessment using a modified Newcastle-Ottawa Scale; pooled prevalence calculated using MetaXL software.
Main Results:
- Five studies involving 205,478 participants were included.
- The pooled prevalence of spectacle non-tolerance was 2.1% (95% CI: 1.6-2.7).
- Refractive errors (47.4%) were the leading cause, followed by communication (16.3%) and dispensing errors (13.5%).
Conclusions:
- Spectacle non-tolerance is influenced by factors in prescription, dispensing, and patient adaptation.
- Vigilance in spectacle prescription and dispensing is necessary to minimize non-tolerance.
- Further research, particularly in under-resourced areas, is needed to enhance refractive error services.

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

01:11Clinical Trials: Overview
4.1K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
