![]() Because of its proprietary technology, the iTrace is the only device that can accurately scan a post-operative patient’s vision. Likewise, the Toric Check provides post-operative guidance on toric axis location without the need for dilation. The iTrace also includes a Toric Planner, which uses unique wavefront Ks, optical alignment angles and printable pictures to help you achieve ideal lens placement during surgery. Being able to track the progression of lens dysfunction and the affect it has on a patient’s vision makes it simple to identify the right time to have a conversation with a patient about lens replacement. The information provided by the iTrace’s best-in-class diagnostic tools can make it easy to find the tailored treatment plan that will improve your patients’ vision. The Dysfunctional Lens Index is a number that you can review with your patients to track the progression of the aging lens over time. It’s the best way to get a complete picture of what’s occurring when a patient isn’t satisfied with their vision.īetter education. ![]() And, it helps you understand exactly how these errors affect your patients’ visual performance. It uses objective metrics to help you assess progression of corneal and lens dysfunction. It lets you identify and map higher and lower order aberrations throughout the anterior segment. ![]() ![]() Because the iTrace uses the industry’s most accurate method of analyzing vision, it gives you more complete, reliable information about your patients’ vision. doi: 10.1016/s0886-3350(01)01279-2.THE ITRACE IS BEYOND COMPARE BECAUSE IT HELPS YOU PROVIDE…īetter information.

Limbal relaxing incision during cataract extraction versus photoastigmatic keratectomy after cataract extraction in controlling pre-existing corneal astigmatism. Analysis of biometry and prevalence data for corneal astigmatism in 23 239 eyes. It can eliminate the potential systematic errors resulting from varying head positions during the preoperative keratometry measurement and from manual marking. The TRP marking method using the iTrace aberrometer is simple and accurate for preoperative marking of toric IOLs. The mean toric IOL misalignment was lesser but without significance in the TRP marking group than in the SHM marking group after 3 postoperative months (2.66° ± 1.42° versus 3.29° ± 1.67° P=0.295). There was no statistically significant difference in BCVA, UDVA, preexisting corneal astigmatism, or residual astigmatism between the groups before or after surgery ( P > 0.05). The follow-up duration was 3 months after cataract surgery.įifteen eyes of 15 patients were in the TRP marking group and 15 eyes of 15 patients in the SHM marking group. TRP marking involved marking three points randomly in the corneal limbus of the patients and accurately marking the horizontal meridian was not required. All patients were prospectively randomized into the TRP marking group or slit-lamp horizontal meridian (SHM) marking group. Thirty eyes of 30 patients undergoing cataract surgery with coexisting corneal astigmatism of over 1.0 D were included in this study. ![]() Prospective, randomized comparative trial.
