Review
Presbyopia is the progressive loss of accommodation. Accommodation is a quick, precise and involuntary action which enables the eye to change the power of the young crystalline lens to see clearly at all distances. Presbyopia is and age-linked physiologic phenomenon: it results from aging of the lens, which loses its elasticity, gradually becomes rigid and loses the ability to accommodate. Presbyopia has attained a prevalence of 80% in Europe and is increasing regularly due to the aging of the population. Various surgical techniques can be proposed. Indications depend on age, ophthalmological exam, and any associated ametropia. The main techniques act by either changing the curvature of the cornea with laser or with an intrastromal inlay to create pseudoaccomodation, or by intraocular lens surgery with a multifocal or accommodating IOL. Once the surgical choice has been made, the information must be clearly conveyed and consent obtained.

UNLABELLED
Presbyopia is the most common refractive disorder for people older than 40 years. It is characterized by a gradual and progressive decrease in accommodative amplitude. Many surgical procedures for the correction of presbyopia exist, with additional procedures on the horizon. This review describes the prevalent theories of presbyopia and discusses the available surgical options for correction.

Review
Presbyopia affects more than 1 billion people worldwide, and the number is growing rapidly due to the aging global population. Uncorrected presbyopia is the world's leading cause of vision impairment, and as with other causes. The burden falls unfairly on low- and middle-income countries (LMICs), in which rates of presbyopic correction are as low as 10%. The importance of presbyopia as a cause of vision impairment is further underscored by the fact that it strikes at the heart of the productive working years, although it can be safely and effectively treated with a pair of inexpensive glasses. To galvanize action for programs to address uncorrected presbyopia in the workplace and beyond LMICs, it is crucial to build a solid evidence base detailing the impact of presbyopia and its correction in important areas such as work productivity, activities of daily living, visual function, and quality of life. The aim of this review was to provide an up-to-date reference for program planners and policymakers seeking to build support for programs of presbyopia correction, particularly in low-resource settings.

Review
PURPOSE OF REVIEW
This review outlines concepts in intraocular lens (IOL) optics and aberrations important both for current IOLs and for new IOLs in development.
RECENT FINDINGS
Optical aberrations make a significant impact on the laboratory and clinical performance of IOLs, especially under mesopic and low-contrast conditions. Minimizing or correcting these aberrations can potentially improve visual function. Strategic management of aberrations can have clinical utility for extended depth of focus and presbyopia correction.
SUMMARY
All IOLs affect ocular aberrations in some manner. It is important for clinicians and researchers to understand the implications how any residual aberrations could affect visual quality, visual side-effects, and depth of focus.

Review
PURPOSE OF REVIEW
Presbyopia is an inevitable age-related loss of accommodation that results in spectacle dependence with common everyday near-vision tasks. Many surgical approaches to presbyopic correction have been investigated, with monovision correction being amongst the most common and attractive options. In this article, we will review the advantages and disadvantages of the new modalities of presbyopic monovision correction.
RECENT FINDINGS
New methods such as mini-monovision, corneal inlays, and multifocal corneal ablation aim to maximize stereopsis and decrease the anisometropic side effects of conventional monovision. These include inlays such as the KAMRA and Raindrop, and phakic intraocular lenses such as the hole ICL. Newer corneal laser refractive procedures such as small incision lenticule extraction have also shown good outcomes with monovision. Pseudophakic monovision using standard monofocal lenses still provides good results.
SUMMARY
Monovision for presbyopic correction continues to provide promising results. There are a number of new devices and techniques that have shown good visual acuity outcomes, patient satisfaction and spectacle independence.

PURPOSE OF REVIEW
Presbyopia is the normal progressive loss of accommodation, which leads to the inability to focus clearly on objects located at different distances. Some of the accepted methods for treating this condition are glasses, contact lenses, and surgery. Pharmacological treatments are a new and promising noninvasive option for dealing with presbyopia. The aim of this review is to provide an update on some recent advances in this field.
RECENT FINDINGS
Currently, there are three different strategies for the pharmacological treatment of presbyopia. The first one aims to produce miosis and increase depth of focus through a pinhole effect, therefore improving uncorrected near visual acuity. The second one tries to restore the elasticity the lens has lost due to aging. Finally, the third strategy is based on rehabilitating accommodation; which is to say, in a binocular way, allowing for good vision at all distances.
SUMMARY
Pharmacological treatments are a new alternative that expands the diversity of existing strategies for treating presbyopia. These treatments are based on the instillation of eyedrops with different compositions, which vary according to the different strategies. Many of these developments will most likely be on the market in the next few years. If the process of patient selection is done properly, any one of these three strategies can be used successfully.

Review
Multifocal intraocular lenses are increasingly used in the management of pseudophakic presbyopia. After multifocal intraocular lens implantation, most patients do not need spectacles or contact lenses and are pleased with the result. Complications, however, may affect the patient's quality of life and level of satisfaction. Common problems with multifocal lenses are blurred vision and photic phenomena associated with residual ametropia, posterior capsule opacification, large pupil size, wavefront anomalies, dry eye, and lens decentration. The main reasons for these are failure to neuroadapt, lens dislocation, residual refractive error, and lens opacification. To avoid patient dissatisfaction after multifocal intraocular lens implantation, it is important to consider preoperatively the patient's lifestyle; perform an exhaustive examination including biometry, topography, and pupil reactivity; and explain the visual expectations and possible postoperative complications.
