See more An autoclave is a machine that uses pressured steam for a predetermined amount of time to sanitize materials and equipment. It is utilized in industrial, medicinal, and laboratory environments where it kills bacteria and spores by .Chemical indicators are required when using a steam sterilization process to verify that the critical parameters of the cycle were met. The way chemical indicators are used with an autoclave process depends on the indicator Type and sterilization cycle.

This study followed the tenets of the Declaration of Helsinki, and the Institutional Review Board of Chuncheon Sacred Hospital and Incheon St. Mary’s Hospital approved the protocol. Patients were recruited at the Cornea Service of Chuncheon Sacred Hospital. The study included healthy subjects (n = 49) . See moreThe examinations were performed as follows: OSDI, BTT, slit-lamp examination, tBUT, corneal stain, and Schirmer I (without anesthesia) . See moreThe order of the testing procedures during the ophthalmic examinations was as follows: 1. 1.Subjective interview regarding symptoms of dry eye . See moreThe BTT test was performed in eyes of all participants by the same clinician. The BTT test was conducted in a silent and windless examination room. The temperature and . See more
All statistical analyses were performed using SAS software (ver. 9.0; SAS Institute, Cary, NC, USA). A value of P < 0.05 was considered statistically significant, and 95% confidence intervals (CIs) were calculated. The mean ± standard deviation . See more
Tear film instability is usually evaluated by a simple tear break-up time (BUT) test using a vital . The tear film breakup time (tBUT) is a clinical evaluation of evaporative dry eye disease assessed by instilling topical fluorescein into the eyes. In the present study, we introduce a new diagnostic test, blinking tolerance time (BTT), for self-evaluation of tear-film stability.

Tear film instability is usually evaluated by a simple tear break-up time (BUT) test using a vital dye, fluorescein. Some of the newer imaging techniques offer non-invasive ways to measure BUT. Tear osmolarity can be directly measured using a point-of-care device in-office.
This review examines various techniques that are used to assess tear film instability: evaluation of tear break-up time and non-invasive break-time; topographic and interferometric techniques; confocal microscopic methods; aberrometry; and visual function tests. A TBUT of less than 10 seconds indicates reduced tear film stability and is suggestive of dry eye syndrome, particularly evaporative dry eye. Shorter TBUT values may correlate with symptoms such as eye discomfort, blurred vision, and fluctuations in vision quality. With this in mind, ECPs can assess the stability of the tear film by checking the tear meniscus, TBUT, and osmolarity, as well as understand that hyperosmolarity can result from many different pathways, such as aqueous and lipid deficiencies, environmental stimuli, inflammatory disease, and autoimmune disease.

In the present study, we introduce a new diagnostic test, blinking tolerance time (BTT), for self-evaluation of tear-film stability. We compared the results with the tBUT and validated the BTT test for self-assessment of tear film instability. “A stable tear film protects and smooths the corneal surface, maintains comfort and quality vision during interblink intervals, and is a key determinant of a successful outcome in vision correction surgeries.” Tear film anatomy and evaluation. The fluorescein tear film break-up time (FTBUT) test is one of the most common tests for dry eye syndrome. This test evaluates the tear film stability. In clinics, one of the main measures for determining dry eye is defined as a FTBUT shorter than 5 s. As tear stability is associated with the level of comfort during contact lens wear, 10 assessing tear film stability is an important part of a contact lens clinical assessment. Clinically, the most popular method for assessing tear stability is using the .
