A study published in the Journal of Cataract and Refractive Surgery found that patients who had implanted diffractive multifocal intraocular lenses (MIOL) and developed complete posterior vitreous detachment (PVD) experienced a decline in their near visual acuity. The study evaluated 475 patients who received a multifocal intraocular lens between 2017 and 2019 and found that complete PVD may hasten age-related worsening of both corrected distance visual acuity (CDVA) and distance-corrected near visual acuity (DCNVA), especially for patients 75 years of age and older. The presence of complete PVD reduces DCNVA in eyes with diffractive MIOL at all ages, particularly in patients aged 75 and older.
