Also, 21.3–22.4% of patients with cataracts have 1.0–1.5 D of corneal astigmatism with 10.6–12.4% of patients having 1.5–2.0 D and 8.2–13.0% of patients having 2.0 D or more. Trial registrationĬurrent Controlled Trials ISRCTN94956424, Retrospectively registered (Date of registration: 05 February 2020).Īn estimated 40–50% of the population aged over 60 years has more than 1.0 diopter (D) of keratometric astigmatism. The findings show that use of iTrace built-in toric calculator is safe and effective for planning toric IOL surgery for wavefront keratometric astigmatism. This is the first study on evaluation of clinical outcomes of toric IOL implantation in corneal astigmatism patients using iTrace wavefront keratometric readings. ![]() The proportion of astigmatism ≤0.50 D increased from 0 to 71.8% postoperatively. Surgical induced astigmatism was 1.73 D ± 0.77 and the mean correction index was 0.89 ± 0.22, showing a slight undercorrection. Postoperative mean refractive astigmatism decreased significantly to 0.48 D ± 0.34. Preoperative mean corneal topographic astigmatism was 1.91 diopters (D) ± 0.69 (standard deviation). Astigmatic changes were assessed using Alpins vector method over a 3-month follow-up period. The IOL power and cylinders were chosen with the help of the iTrace toric planning program using wavefront keratometric astigmatism. The study included 85 eyes of 63 patients undergoing phacoemulsification and toric IOL implantation. Setting: Single site in China, Shanxi Eye Hospital, Shanxi, China. This aim of this study was to evaluate visual outcomes and rotational stability after toric intraocular lens (IOL) implantation using the wavefront aberrometry of the cornea with iTrace. ![]() It was supposed to be more accurate than iTrace simulated keratometry which was calculated based on only 4 points on the circle of 3 mm. The iTrace wavefront aberrometry of cornea calculated steep power and axis based on the best Zernike mathematical fit from all topo data within 4 mm circle. The USB Receiver is also small enough to stay plugged into your computer at all times.Currently, there is no standard technique for determining corneal astigmatism. Featuring a sleek, comfortable design, the Targus Wireless Blue Trace mouse provides wireless convenience and the Micro USB receiver stores underneath the mouse so it's never lost and always ready for travel. The low power indicator light lets you know when a new set of batteries are needed. The mouse comes equipped with two high-quality Energizer® batteries and is designed to provide up to 12 months of battery life depending on usage. Wireless capability eliminates clutter from the workspace while RF 2.4GHz technology significantly reduces cordless interference and signal drops allowing the mouse to work up to 33 feet away. The ergonomic design reduces wrist strain for comfort and the mouse is ambidextrous for both left and right handed users. Blue Trace technology combines the power of optical technology with the precision of laser technology for remarkable tracking on almost any surface including wood, granite, and carpet. The Targus Blue Trace Wireless Mouse features the latest Blue Trace technology for accurate and precise tracking.
