Summary
Ocular surface dysfunction is common in patients seeking cataract surgery, with 80% showing abnormal tear tests. Many patients are undiagnosed, highlighting the need for pre-operative screening.
Area of Science:
- Ophthalmology
- Ocular Surface Disease
- Cataract Surgery
Background:
- Ocular surface dysfunction can impact visual outcomes.
- Prevalence in cataract surgery candidates is not well-defined.
Purpose of the Study:
- To determine the prevalence of ocular surface dysfunction in patients evaluated for cataract surgery.
Main Methods:
- Prospective case series of 120 patients undergoing cataract surgery evaluation.
- Assessed demographics, medical history, slitlamp findings, tear osmolarity, and tear matrix metalloproteinase-9 (MMP-9).
- Defined dysfunction by corneal findings, positive MMP-9, or abnormal osmolarity.
Main Results:
- 80% of patients had at least one abnormal tear test (osmolarity or MMP-9).
- Abnormal osmolarity was found in 56.7%, and abnormal MMP-9 in 63.3%.
- 40% had two abnormal tear test results, indicating significant ocular surface dysfunction.
Conclusions:
- Objective findings of ocular surface dysfunction are highly prevalent in cataract surgery candidates.
- Many patients with dysfunction are asymptomatic and undiagnosed.
- Pre-operative screening for ocular surface dysfunction is recommended.

01:08Prevalence and Incidence
1.9K
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.

01:20Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation
2.6K
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

3.3K
When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...

01:21Cell-surface Signaling
54.5K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

01:29Area of a Surface of Revolution

Surfaces of revolution are formed when a two-dimensional curve is rotated around an axis, producing a three-dimensional shape. This concept is used in engineering tasks like determining the surface area of a rocket nozzle, where precise calculations are critical for applying uniform heat-resistant coatings. When a curve is revolved about the x-axis, it sweeps out a continuous surface whose area must be calculated accurately to estimate material requirements.Approximating with Conical BandsTo...
