This is a series of diagnostic and check-up tests that the patient must always undergo before an eye examination.
This test is essential to assess the shape and the condition of the corneal surface: to define the characteristics of astigmatism if necessary, and allow for them to be corrected; to check suitability for refractive surgery and as a follow-up in the post-operative phase. It is the test of choice to promptly identify certain corneal disorders such as keratoconus.
Pentacam (corneal tomography)
This instrument creates a 3-D image of the cornea which allows precise assessment of its geometric characteristics; it provides an exact measurement of corneal thickness at different points; it uses sophisticated algorithms to calculate the possibility of altering corneal shape with refractive surgery. It is essential in diagnosing keratoconus and in the follow-up stages.
Tests using an Endothelial Microscope
This device measures the number, shape, distribution and condition of the cells of the corneal endothelium.
It is an essential test used to help plan surgery on the anterior segment of the eye, for post-operative monitoring, for the diagnosis of various types of corneal disorders, and for follow-up checks on contact lens wearers.
This device measures the thickness of the cornea. This parameter is essential to help plan any type of refractive surgery and for following up on some corneal disorders.
This is an ultrasonic measurement of the length of the eyeball as a whole and of its different segments. This test is essential to help plan cataract surgery; before the implantation of intraocular lenses to alleviate refractive error; and for support when treating patients affected by serious ametropia and particular forms of glaucoma.
This is an analysis of how a patient’s vision is different in different parts of the eye. It is carried out using a wavefront aberrometer which breaks down the data obtained about the different types of aberration.
