Comparative Study
Effect of illumination on visual function after monofocal and multifocal intraocular lens implantation.
To compare best-corrected visual acuity (BCVA) and contrast sensitivity (CS) under different levels of illumination in patients who had monofocal and multifocal intraocular lenses (IOLs) and to establish the effect of different lighting conditions on vision in the two groups of patients. ⋯ Distance and near BCVA and CS improve with increasing illumination in patients with monofocal and multifocal IOLs, but remain comparable in the two groups under common levels of indoor illumination. Patients with multifocal IOLs may experience worsening of their vision in bright outdoor lights.
