KIAWAH ISLAND, S.C. — Patients implanted with a diffractive extended depth of focus IOL containing a violet light filter showed satisfactory tolerance to induced astigmatism, according to a presenter at Kiawah Eye.
Ryan Rhodes, MD, a fourth-year resident at Medical University of South Carolina Storm Eye Institute, Charleston, South Carolina, said that 30 healthy eyes with normal visual potential were implanted with Johnson & Johnson Vision’s ZXR00V or ZXW model diffractive extended depth of focus (EDOF) IOL with violet light filtration.
The average age of the patients was 65 years, 66% were male, average pupil size was 2.8 mm, and the patients were slightly myopic — close to plano, Rhodes said.
“The mean uncorrected distance visual acuity was right at 20/20,” he said. “The majority of patients could be corrected to that. Near visual acuity was J2. Intermediate visual acuity was close to 20/20.
“Patients tolerated with-the-rule astigmatism pretty well,” Rhodes said. “With oblique astigmatism, it was better. Not surprisingly, against-the-rule astigmatism was less well tolerated.”
Specifically, all 30 eyes had at least 20/40 visual acuity with up to 0.5 D of induced against-the-rule astigmatism, 1 D of oblique astigmatism and 1 D of with-the-rule astigmatism.
The mean astigmatic defocus required to maintain visual acuity within one line was 1.17 ± 0.43 for with-the-rule astigmatism, 1.28 ± 0.51 for oblique and 0.83 ± 0.5 for against the rule, according to the study.
All patients had good to excellent vision according to the Visual Function Questionnaire-25, Rhodes added.
