Abstract


This study investigates the characteristics and clinical outcomes of different types of extended depth-of-focus and multifocal intraocular lenses (IOLs) to determine which IOL can increase patient satisfaction. Modern cataract surgery has undergone tremendous evolution in terms of IOL quality. Recently, different types of presbyopia-correcting IOLs have become commercially available. Among them, multifocal IOLs are the most frequently used. Multifocal IOLs are different from conventional monofocal IOLs because these have multiple focus, which enable patients to see both distant and near objects at the same time. Multifocal IOLs can be classified as either refractive or diffractive IOLs. Diffractive multifocal IOLs include traditional bifocal lenses and relatively new trifocal lenses, and are the most widely used multifocal IOLs owing to their good clinical performance. Trifocal IOLs have an advantage over bifocal IOLs in terms of intermediate visual acuity, but can cause decreased contrast sensitivity and night vision disturbances. Recently developed extended depth-of-focus IOLs are different from traditional multifocal IOLs in that these extend the focus, resulting in smooth continuous focus. It also has the benefit of better contrast sensitivity and improved visual quality over multifocal IOLs; however, is relatively weak in terms of near visual acuity.
