Our network is specialized in eye diagnostic tests and eye chek-up.
Vista Vision eye clinics are equipped with state-of-the-art diagnostic equipment for the main eye diseases for the analysis of both the anterior and posterior surface of the eye (retina).
The diagnostic examinations performed in our clinics guarantee optimal evaluation of eligibility for the laser treatment, a necessary condition for the success of the surgery.
Prevention is the best weapon to assess the eye health status and effectively detect any vision problems and eye diseases, in order to promptly diagnose the outbreak of eye diseases that, in some cases, can impair the patient’s life significantly.
OPTICAL COHERENCE TOMOGRAPHY (OCT)
Optical coherence tomography (OCT) is a non-invasive specialist examination of the eyes which, through an innocuous infrared laser probe, scans the cornea and the retina creating high-resolution tomographic sections, recreates the anatomy of the retinal macular region and diagnoses in advance any eye diseases.
OCT examination is simple, painless and not dangerous and can be performed on any patient. If you have been prescribed the OCT exam and you are looking for a clinic where to book it, you can contact the Vista Vision clinics. Our clinics, equipped with state-of-the-art OTI-SLO II equipment and devices, guarantee 1-week maximum waiting time and immediate medical reports.
Eye autorefractometer is a computerized diagnostic system that, during the complete eye examination, objectively measures the eye refractive error allowing the doctor to diagnose any eye disorders, to form an opinion about the refractive error and to verify if the eye of the patient suffers from vision problems such as myopia, presbyopia, astigmatism, and hyperopia.
Ocular biometry is the measure of the eye size performed by ultrasound.
In particular, ocular biometry allows to:
- measure the axial length of the eyeball before the surgical extraction of the
crystalline lens (in case of cataract), in order to determine the possibility to
implant artificial crystalline lens;
- monitor the evolution of some diseases that change the ocular length
(congenital glaucoma in young children, atrophy of the traumatized eye);
- distinguish between a megalocornea (large cornea, non-pathological nature) and a buphthalmos (eye enlargement in congenital glaucoma), between a microcornea (small cornea, non-pathological nature), and a microphthalmia (non-functional decrease of the eye diameter). The probe allows ultrasound to be reflected and is placed on the cornea, after topical anaesthesia with eye drops. This completely innocuous test lasts a few minutes and gives immediate results.
Campimetry is a non-invasive diagnostic test that assesses, by projecting a small light source, the sensitivity and the functional state of the retina in the different regions of the visual field. This test is crucial for the study of glaucoma and for any neurological disease affecting the optic nerve.
Keratometry is a diagnostic eye test for examining the cornea; it consists in measuring the curvature radius of the cornea anterior surface and allow to obtain useful information to assess the eye refractive errors, especially to quantify astigmatism and to accurately measure the visual acuity of the patient. It is also an essential computerized technique for the early detection of keratoconus and in the procedures preceding cataract surgery.
ENDOTHELIAL CELL COUNT
Endothelial cell count is a test to verify the number of cells in a corneal endothelium area. Corneal endothelium is the innermost layer of the cornea, made up of many cells which, due to aging or traumas, may in part get damaged leading to diseases like corneal oedema. This is why it is important to monitor the corneal endothelium state of health.
Corneal pachymetry is a test to measure the thickness of the cornea, used to assess the ocular tone (in particular in those patients with glaucoma) and to evaluate the eligibility for the excimer laser treatment in refractive surgery. Corneal pachymetry may also be useful for analysing specific corneal pathologies such as glaucoma and keratoconus.
Dynamic pupillometry is a test to measure the pupil diameter in different light conditions and allows to adjust the intervention parameters in order to prevent the patient from suffering from halos; this test is particularly useful and recommended in laser refractive surgery treatments. Pupillometry is performed without the administration of atropine because the pupil must be able to contract and dilate.
Applanation tonometry is the most widely used procedure to measure the intraocular pressure and is fast and painless. It is performed after instilling an anaesthetic eye drop and one dye drop. Then, a tiny plastic cone is gently placed onto the cornea and the resistance it meets in applanating the surface of the cornea is measured on a graduated scale and expressed in millimetres of mercury.
Corneal topography is a diagnostic computerised test that allows to easily and safely measure the morphology and curvature of the corneal surface, creating a coloured map (called corneal map) in which each colour corresponds to a more or less accentuated curvature. Areas of flatter curvature are displayed in cool colours, whereas areas of steeper curvature are illustrated in warm colours. The use of a corneal topographer does not entail the contact with the eye, therefore it is an absolutely non-invasive examination.
