iTrace – A Ray Tracing Aberrometer

Modern ophthalmology focusses on visual quality and not just visual acuity. The quality of vision is affected by both lower and higher order aberrations. An optical aberration is a departure of the performance of an optical system from the prediction of paraxial optics. In this article, we analyse t...

Description
Summary:Modern ophthalmology focusses on visual quality and not just visual acuity. The quality of vision is affected by both lower and higher order aberrations. An optical aberration is a departure of the performance of an optical system from the prediction of paraxial optics. In this article, we analyse the iTrace Ray-tracing aberrometry and its applications in daily clinical practice. The iTrace system integrates corneal topography with wavefront aberrometry, thereby providing a unique analysis that subtracts corneal from total aberrations in order to isolate the internal aberrations of the eye. It is an extremely useful tool for objective evaluation of dysfunctional lens, improving cataract and refractive surgery outcomes and planning of premium intraocular lenses. Thus, the clinicians must explore this instrument as it is an advanced diagnostic tool that can help the surgeon at all stages of patient care in achieving premium outcomes.
