The Dry Eye Syndrome is a disease in which there is an alteration of the composition of the tear and a greater instability of the lacrimal layer.
The Lacrimal Osmolarity Test allows us to measure the degree of salinity of the tear, which is indicative of the stability of the lacrimal layer, so we can objectively determine the degree of Ocular Dryness allowing us to make an early diagnosis and also assess the effect of prescribed medications by our ophthalmologists.
To obtain this value we use a microchip coupled to a meter that collects a small amount of tear at the edge of the eyelid, this meter is placed in a reader and seconds later we obtain the specific value of the osmolarity of that tear sample.
What is Refractive Surgery? Lasik or ICL Lense?
/in Cirugía Refractiva, Videos /by miriam sorellDr. Jorge Castanera explains the two main techniques to eliminate the dependence of glasses and contact lenses for myopia, hyperopia and astigmatism.

Retina: OCT Angiography
/in Retina /by miriam sorellOCT (Optical Coherence Tomography) Angiography is an important advance in OCT technology because it allows obtaining an accurate image of the vascular tree of the retina without injecting an intravenous contrast as in fluorescein angiography without any side effect.
The A-OCT is a safe and non-invasive test that, by projecting a beam of light on the retina, will provide us with valuable information about the vascular flow, being able to diagnose diseases such as age-related macular degeneration (AMD), macular ischemia, …

Laser Surgery diagnostic platform
/in Refractive Surgery /by miriam sorellThe new Orbscan3 Anterior Segment Analyser is the evolution of its predecessor topographer. By means of a scan, this new analyser enables us to perform an exam without eye contact, and it contributes to a higher resolution as it scrutinises three times more points.
The ZDW3 aberrometer analyses nine times more points than the previous generation and it accurately determines which the optical irregularities of the eye are and how to treat them with Refractive Laser Eye Surgery.
In Castanera Institute of Ophthalmology we are again using cutting-edge technology to perform accurate diagnoses and hence optimized treatments for our patients.
