Aberrometry is an investigation that studies optical imperfections, known as optical aberrations, both corneal and internal to the eye
What is aberrometry used for?
All eyes have optical aberrations or imperfections. Some, such as myopia, hypermetropia and astigmatism can be corrected with lenses: contact lenses or glasses. These are called lower-order optical aberrations. But there are other, more specific optical aberrations, called high-order aberrations, which cannot be corrected with normal corrective lenses and cause vision imperfections. The purpose of the examination is to detect and measure the presence of any type of optical aberration.
Osiris, is a total ocular aberrometer, and is indispensable for the correct assessment of patients who have, in addition to standard errors, more complex ocular aberrations.
Osiris has a unique design that allows it to measure aberrations with a resolution of 45,000 points (at maximum pupil diameter) with a wide dynamic range. This device is particularly important for measuring spherical aberrations in preparation for Presbyond laser surgery or multifocal lens implant surgery.
