Toric IOL shows good visual outcomes in select astigmatism cases
SAN DIEGO — Use of a toric IOL demonstrated satisfactory visual outcomes in highly astigmatic irregular cornea cases that had undergone previous surgery, according to a poster here.
Arturo Ramirez-Miranda, MD, and colleagues conducted a 12-month follow-up of patients implanted with the AcrySof toric IOL (Alcon). They presented their results in a poster study at the American Society of Cataract and Refractive Surgery meeting.
"The AcrySof toric IOL is a reliable and reproducible option for correcting corneal astigmatism during cataract surgery," they said.
In the study, patients had previously undergone hexagonal keratotomy, penetrating keratoplasty or radial keratotomy. All patients were required to have stable astigmatism for 4 months.
According to the study, a significant reduction in refractive astigmatism occurred, but there was no statistically significant difference in preoperative and postoperative corneal astigmatism.
At 1-year postop, patients' vision improved dramatically, and the IOL aligned despite mild anterior capsule contraction, according to the researchers.
"Toric IOLs can be a great measure in well-selected cases with stable astigmatism," Dr. Ramirez-Miranda and colleagues said.
