Toric IOLs offer greater efficacy for treating regular astigmatism
NEW YORK — A new generation of toric IOLs now offers more precise correction for regular astigmatism because of sophisticated vector analysis software, which refines IOL power calculations and improves postoperative axis alignment, according to a surgeon speaking here at the OSN New York meeting.
Warren E. Hill, MD, said toric IOLs work best in patients with regular astigmatism. The main advantage of such IOLs over other lenses is that they solve accuracy problems by providing a more precise refractive correction.
"That's where the toric lens really shines," Dr. Hill said.
In comparing the lens with LASIK and limbal relaxing incisions, Dr. Hill said toric lenses are more stable and provide better, more precise astigmatic corrections. Limbal relaxing incisions lack precision, while LASIK often requires a second surgery and is more expensive, he said.
"Now, we can actually keep our promise to patients of precise correction of the basic macular component of the cornea," Dr. Hill said. "They are the first choice of lenses in my practice for correcting corneal astigmatism."
