Efficacy of Artificial Tears Based on an Extract of Containing Dinucleotides in a Rabbit Dry Eye Model.

(1) Background: is a brine shrimp containing high concentrations of dinucleotides, molecules with properties for dry eye treatment. For this reason, the purpose of the study was to evaluate the effect of the artificial tears based on an extract of in a rabbit dry eye model. (2) Methods: A prospective and randomized study was carried out.

Stabilization of comfort and visual quality after the insertion of soft contact lenses.

Purpose: To evaluate comfort, visual function, and in vivo wettability after the insertion of hydrogel and silicone hydrogel contact lenses for a better understanding of how long practitioners should wait for the initial evaluation of soft contact lenses.

Methods: A short-term prospective, contralateral, randomized, and participant-masked study was carried out. Twenty healthy participants (25.

Changes in visual quality with soft contact lenses after the instillation of hyaluronic acid eye drops.

Purpose: To evaluate the changes in visual function and anterior surface aberrations during soft contact lens (SCL) wear after the instillation of hyaluronic acid (HA) eye drops with different viscosity.

Methods: A prospective, randomized, and participant-masked study was performed. Twenty healthy participants (25.

Preclinical Development of Artificial Tears Based on an Extract of Artemia Salina Containing Dinucleotides in Rabbits.

Purpose: To evaluate the preclinical efficacy of eye drops based on an extract of Artemia salina on the ocular surface of rabbits. Tear secretion, tear break-up time and corneal staining were measured.

Material And Methods: A preclinical and short-term prospective study was performed.

Effect of nutritional supplement based on melatonin on the intraocular pressure in normotensive subjects.

Purpose: To evaluate the effect of a new nutritional supplement based on melatonin on the intraocular pressure (IOP) in normotensive subjects.

Patients And Methods: A short-term prospective study was designed. Sixty-seven normotensive subjects were recruited.

Evaluation of tear meniscus by optical coherence tomography after different sodium hyaluronate eyedrops instillation.

Purpose: To evaluate changes in tear meniscus dynamics using optical coherence tomography (OCT) after the instillation of different concentrations of sodium hyaluronate (SH) ophthalmic solutions.

Methods: An experimental, double-masked, randomized study was performed. Twenty-three healthy subjects (16 women and seven men; mean age 23.

Therapeutic inhibitors for the treatment of dry eye syndrome.

Dry eye disease (DED), defined as a multifactorial disease of tears and ocular surface, results in symptoms of discomfort, ocular irritation, visual disturbance and tear film instability. This syndrome is accompanied of ocular surface inflammation and it is produced by a deficient activity of the lacrimal functional unit. In addition, it is associated with systemic autoimmune diseases such as Sjögren´s Syndrome, rheumatoid arthritis, systemic lupus erythematosus and some drug administration.

Post-lens tear turbidity and visual quality after scleral lens wear.

Background: The aim was to evaluate the turbidity and thickness of the post-lens tear layer and its effect on visual quality in patients with keratoconus after the beginning of lens wear and before lens removal at the end of eight hours.

Methods: Twenty-six patients with keratoconus (aged 36.95 ± 8.
