WebThis is probably caused by symmetrical refractive index changes within the nucleus of the lens, causing negative spherical aberration and a myopic shift. 18,19 In our small sample, this occurred in approximately half the subjects with nuclear cataract. WebNov 11, 2024 · The time to refractive stability may vary from 1 day to 3 months postoperatively. Patients with one-piece acrylic lenses may typically be refracted within the first week postoperatively whereas those with premium IOLs should not be refracted until postoperative month 1. Post-RK patients may take 3 months for refractive stability.[20]
