Question: Can you use a toric IOL for cataract surgery that corrects down to 1.50, for astigmatism that is only 0.75?
Answer: Toric lensimplant calculation may not match the amount of astigmatism in your eyeglasses. Is the .75 the eyeglass refraction? Is the astigmatism on the cornea as demonstrated by the corneal topography? Is the astigmatism with the rule or against the rule? Is the placement of the incision going to impact the position or the degree of the astigmatism postoperatively? And there is more to be considered in the calculation. Please leave the calculation to your cataract surgeon and if you don’t feel confident with his or her choice then get a second opinion.
