Multifocal Intraocular Lenses: Neuroadaptation

2014
Neuroadaptation is a learning process in which our brain reacts to a previously inexistent sensory input and its ability to adapt to it by ignoring it or using it properly. Neuroadaptation is a major concern while implanting multifocal intraocular lenses since these lenses, in order to achieve multifocality, reduce contrast sensitivity and make at ...

Visual outcomes with multifocal intraocular lenses

Current Opinion in Ophthalmology, 2000
Multifocal intraocular lenses (IOLs) are increasingly becoming a part of the armamentarium of cataract and refractive surgeons. Reports show that most multifocal IOLs provide excellent visual outcomes. In one major study of a zonal progressive, refractive, multifocal design, more than 80% of patients were able to see 20/40 or better at distance and J3 ...

Multifocal Intraocular Lenses: Basic Principles

2019
Multifocal intraocular lenses (MIOLs) can be made using refractive and diffractive surfaces or combinations of both. Depending on the optical design, MIOLs can be called bifocal or trifocal lenses. Bifocal IOLs provide foci for far and near distances, and trifocal lenses add a focus for intermediate distances.

Multifocal Intraocular Lenses: Preoperative Considerations

2014
Planning ahead cataract surgery with multifocal intraocular lens implant is of great importance and has a huge impact on the surgical result. Multifocal intraocular lenses can obtain multifocality in different ways and can be designed as diffractive, refractive, or as a combination of designs.

Multifocal and Accommodating Intraocular Lenses

2020
The loss of accommodation that accompanies pediatric cataract extraction presents several unique challenges not encountered in the management of presbyopia typical in adult cataract surgery. However, many adult techniques and technologies are useful to consider in the pediatric age group. Any implantation of intraocular lenses, regardless of design, is

Multifocal Intraocular Lenses: The Challenges

2014
Modern lifestyles and quality of life are constantly improving. Cataract surgery and intraocular lens (IOL) implantation have evolved over the last decade, and the improvement of the quality of vision of patients utilizing these advances is therefore one of the main aims of today’s cataract surgeons.

Complications of Multifocal Intraocular Lenses

2018
Patient satisfaction after multifocal IOL implantation is reviewed in this chapter. The main reasons leading to patient complaint and dissatisfaction are deeply analyzed. The best treatment options for all these clinical situations are described, as well, along the chapter. IOL explantation, although rare, is the worst scenario possible after

[Multifocal intraocular lenses. A review].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2001
Modern cataract surgery has developed tremendously during the past 10-15 years. Improved surgical techniques, as well as improved implant materials and designs, have enlarged patient profiles and indications for cataract surgery. This also created much higher expectations from the patients' site. The loss of accommodation is loss of quality of life for
