SAN DIEGO — A newly developed toric microincisional IOL provides good visual acuity through the correction of astigmatism compared with previous reports; however, further follow-up studies are needed, a presenter reported here.
"The purpose of our study was to evaluate postoperative outcomes of a newly developed toric microincision intraocular lens," Hiroko Bissen-Miyajima, MD, PhD, OSN Asia-Pacific Edition Chairperson of the Editorial Board, said at the American Society of Cataract and Refractive Surgery meeting. "We included 19 eyes of 14 patients who received the IOL."
Three lens models, NHT15, NHT23 and NHT30 (Hoya), were studied, Dr. Bissen-Miyajima said. She and colleagues evaluated patients' uncorrected and corrected distance visual acuity, corneal and manifest astigmatism, and IOL rotation.
At 1-month follow-up, there was no statistical difference for corneal stigmatism; however, manifest astigmatism was significantly reduced. Additionally, 94.7% of patients had 20/25 vision or better, which had improved from previous reports, and an IOL rotation of 3.66°, which was similar to a previous report, according to Dr. Bissen-Miyajima.
"This suggests the proper correction of preoperative astigmatism by toric IOL," she said.
