![]() This review will help all the ophthalmologists including residents and fellows learn the principle, features, and clinical applications of iTrace. In this review, our prime focuses on Ray Tracing aberrometer, iTrace. A variety of aberrometers with different principles are available, such as Ray Tracing, Hartmann-Shack, Tscherning, and automatic retinoscopy. Aberrometers are the most vital instruments used for estimating optical aberrations so that a more comprehensive understanding of optical error can be quantified and corrected. The QoV is primarily affected by both higher- and lower-order optical aberration. Moreover, they are the departure of the performance of an optical system from the predictions of paraxial optics. Optical aberrations are defect in a lens or a mirror prevents light rays from being focused at a single point and results in a distorted or blurred image. Similarly, the quantity of vision is documented by measuring uncorrected and best-corrected distance visual acuities. The QoV is an integration of varied optical and neural factors. The quality of vision (QoV) can be easily assessed by documenting objectively the higher-order aberrations or by using subjective questionnaires available. A combination of both determines the final visual acuity. This way, you can avoid any system-related technical issues.Visual acuity is the sum of qualitative and quantitative factors. In addition, you can check the minimum system requirements of the emulator on the official website before installing it. If you follow the above steps correctly, you should have the ADPRO iTrace ready to run on your Windows PC or MAC. #Itrace login apk
