ABSTRACT
Presbyopia is pathophysiological process that begins after age of 40 years, associated with the loss of accommodation. This results in blurred vision of nearby objects. In recent years, there has been rapid technological development of premium intraocular lenses, allowing presbyopia correction cataract surgery. Among this type of intraocular lenses are multifocal intraocular lenses and extended depth of focus intraocular lenses. Extended depth of focus intraocular lenses utilise various optical phenomena – spherical aberrations, chromatic aberrations, diffraction, and refraction – to increase the depth of focus and provide patients with good vision at various distances. Extended depth of focus intraocular lenses mitigate presbyopia and reduce patients’ dependence on glasses. Proper ophthalmological assessment of patients, combined with a detailed consultation regarding their visual needs and occupational demands, ensures high satisfaction and positive outcomes following surgery with implantation of extended depth of focus intraocular lenses.
