It is based on population averages for posterior corneal astigmatism, and it requires the user to integrate data from multiple ocular tests in just the right way, he noted. Alcon is on Facebook.

The slideshow above outlines the Baylor Nomogram. Past president of ISRS. J Cataract Refract Surg. As you normally would, measure the anterior corneal curvature and other refractive and intraocular parameters for calculating IOL power.

Use a calculator that allows you to factor in your SIA. For best results, however, Dr. The researchers tested the eyes with five ocular assessment devices and compared the results. Furthermore, he noted that the surgeon can resolve his or her doubts about the toric accuracy of the chosen IOL by performing an aphakic refraction on the operating table.

That cannot be based on guesswork. Vukich, MD, at a meeting earlier this year. They found that four of the devices—including a manual keratometer and the widely used IOLMaster partial coherence interferometer—overestimated total corneal astigmatism in eyes that had WTR toric error by 0.

The mean value was —0. Trattler, MD, said he accepts the studies, and he does consider posterior curvature when evaluating patients for surgery. Like us at www. Like other innovations that began in refractive surgery, analysis of the posterior curvature and its impact on visual acuity will spread into everyday ophthalmic practice, he predicted.

In eyes with WTR astigmatism. This is straightforward, as most online calculators do this. Koch and colleagues at Baylor set out to test that long-standing assumption.

Designed to improve toric outcomes in astigmatic patients by helping select Toric IOLs with accuracy, the toric calculator is an invaluable tool for developing surgical plans. Online calculators will soon be doing this, he said. In eyes with oblique astigmatism. In contrast to the complexity of the Baylor Nomogram, online calculators for planning and evaluating toric corrections may be easier to use, but they have not been researched as extensively as the Baylor approach.

Toric IOL Calculator

Only about 15 percent of U. In these calculations, the posterior corneal curvature and the anterior curvature are assumed to have a constant ratio. The Barrett Toric Calculator is a one-step formula that shows great promise for calculating IOL toricity and recommended alignment. The calculator includes an optimized user interface and integrates the Barrett Toric Algorithm.

Our purpose is reimagining eye care, and we do this through innovative products, partnerships with eye care professionals and programs that enhance access to quality eye care.

Preliminary data look excellent, Dr. The devices underestimated corneal astigmatism in ATR eyes by 0. When they measured eyes, they found that posterior curvature varied widely. It helps surgeons to select the appropriate toric IOL model and power.

Learn more at www. Trattler said he, too, looks forward to the availability of better testing devices, he is not greatly concerned about the status quo. However, in eyes that had preop WTR corneal astigmatism, Galilei had a significant prediction error of 0. Now and in the Future So far, these findings about posterior corneal astigmatism are an issue primarily for anterior segment surgeons whose patients want a surgical fix for their astigmatism.

The Baylor Nomogram Because no single high-tech device has yet solved the riddle of accurately measuring posterior corneal curvature, Dr. Why Not an Online Calculator? Target on or slightly below the measured astigmatism, and, when inserting the toric IOL, be sure not to err in orienting on the WTR side of the steep meridian since the cornea is likely to drift ATR.

Our products touch the lives of more than million people each year living with conditions like cataracts, glaucoma, retinal diseases and refractive errors, and there are millions more who are waiting for solutions to meet their eye care needs.

Chairman and managing director, Dr. The nomogram calls for surgeons to factor in their average SIA, which for most surgeons is 0.

Koch said his research group developed the Baylor Nomogram to help surgeons improve their refractive outcomes with toric IOLs.Barrett Toric Calculator K Index K Index +ve Cylinder-ve Cylinder.
