Extended Depth of Focus Intraocular Lenses as a Correction for Presbyopia

Okulistyka
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.

Clinical Trials of Exterior Non Implanted Interference-Based Extended Depth of Focus Intra Ocular Lens Design

Photonics, 2014
In this paper, we present the clinical trials performed with intra ocular lens (IOL) design, realizing an interference-based extended depth of focus concept, with an external glass plate. The purpose of such extended depth of focus-based IOL design is to

Visual Performance of Two Designs of Myopia Management Soft Contact Lenses Compared with a Monofocal One in Young Adults

Journal of Ophthalmic & Vision Research, 2023
Purpose: To compare the visual performance of two distinct types of soft contact lenses (CL) aimed at slowing down myopia progression with the performance of a monofocal soft CL. Methods: In a prospective double-masked, crossover trial, 18 myopic adults (

Halo in extended depth of focus and bifocal intraocular lenses [PDF]

, 2022
Purpose: To evaluate the size and intensity of the halos generated in distance vision by bifocal and extended depth of focus (EDOF) intraocular lenses (IOLs) as a function of pupil size, lens base power and lens addition.

Depth perception with gaze-contingent depth of field [PDF]

, 2014
Blur in images can create the sensation of depth because it emulates an optical property of the eye; namely, the limited depth of field created by the eye's lens. When the human eye looks at an object, this object appears sharp on the retina, but objects

Optimization of angular diffractive lenses with extended depth of focus [PDF]

, 2020
Conventional refractive lenses concentrate the incident light at focal distance. A narrow beam waist can be achieved by increasing the lens numerical aperture, but strongly reduces the depth of focus.

Influence of angle alpha on visual quality after implantation of extended depth of focus intraocular lenses

BMC Ophthalmology, 2022
Background To assess postoperative changes in angle alpha, and to evaluate the postoperative visual quality of patients with different angle alpha values after implantation of extended depth of focus (EDOF) intraocular lenses (IOLs). Methods Seventy-nine
