Residual Astigmatism

NEW YORK — In this Healio Video Perspective from OSN New York, John P. Berdahl, MD, discusses potential factors for residual astigmatism after cataract surgery.

Toric IOLs are an invaluable tool in the cataract surgeon’s armamentarium, not difficult to use and beneficial for the practice and patients, according to one presenter.

NEW ORLEANS — In this Healio Video Perspective from the AAO meeting, Dee Stephenson, MD, discusses her research investigating the use of femtosecond lasers to align toric IOLs and reduce residual astigmatism.

Residual astigmatism, even at low levels, can degrade visual acuity after intraocular surgery, according to a study published in the Journal of Cataract & Refractive Surgery.

Femtosecond laser-assisted capsulotomy marking produced lower residual astigmatism and better visual outcomes compared with conventional slit lamp-assisted manual marking during toric IOL implantation, according to a study.
