Artificial Eyes and Tear Measurements

Ophthalmology, 1980
Ninety-four consecutive persons with unilateral enucleations or eviscerations were tested by the Schirmer I and Schirmer II tests for tear production. The findings on the artificial eye were compared with those on the companion, living (control) eye. The collected data were subjected to statistical analysis.

What's Artificial in Artificial Tears?

American journal of optometry and physiological optic, 1986
ABSTRACT After reviewing tear film physiology, and tear film disorders, the author discusses the ingredients found in artificial tear solutions. Choosing the best artificial tear solution for each patient is often confusing because many solutions are available.

Rheological Behavior Patterns in Artificial Tears

Optometry and Vision Science, 2022
SIGNIFICANCE Rheological patterns were objectively calculated considering the first and last viscosity, besides the difference of viscosity with a specific shear rate. Shear thinning, shear thickening, thixotropic, and Newtonian behavior patterns were found.

Classification of Artificial Tears

1998
Natural tears serve three main functions: they maintain the metabolism of the ocular surface tissues, afford a smooth surface that allows regular light refraction, and lubricate the ocular surface to facilitate blinking. They also have other functions, such as specific and non-specific antimicrobial and buffer effects, etc. Natural tears have a complex

Artificial Tear Issues

1994
The designing of artificial tear products has been undergoing constant reevaluation for many decades. Currently available artificial tear formulations differ remarkably with regard to their compositions. Today, significant controversies exist among pharmaceutical scientists in this field.

Toxic preservatives in artificial tears

Ugeskrift for Læger
Dry eye disease (DED) is a common condition, especially among the elderly. Artificial tears are formulated to relieve the symptoms of DED. However, selecting the most suitable option can be challenging, as the products differ in various aspects, including eligibility for reimbursement, pricing, packaging formats, composition, and presence of ...

Effect of preservatives in artificial tear solutions on tear film evaporation *

Ophthalmic and Physiological Optics, 1991
It has been suggested that certain preservatives in artificial tears may affect the stability of the tear film lipid layer. In the present study, tear film evaporation rate (TER) was measured with a modified Servomed Evoporimeter to determine whether preservatives affected tear stability. Two solution combinations were compared in a cross‐over study of

Effect of Artificial Tear Solutions and Saline on Tear Film Evaporation

Optometry and Vision Science, 1990
ABSTRACT The effect on tear evaporation of two artificial tear solutions is compared with that of an equal volume of saline instilled into the eye. Changes in tear evaporation rates (TER) were measured with a modified Servomed Evaporimeter in a cross‐over study of nine subjects.

Stability of Cyclosporine 1% in Artificial Tears

Journal of Ocular Pharmacology and Therapeutics, 1996
We wished to determine the stability of frozen, refrigerated, and room temperature topical cyclosporine 1% in artificial tears (Tears Plus). Cyclosporine 1% eye drops were made in artificial tears prior to the manufacturers recommendations of using a lipid soluble vehicle, such as olive oil.
