Visual disturbances during prolonged space missions
This article reviews symptoms, likely causes, and potential solutions, such as lower body negative pressure, to counteract space-associated neuroocular syndrome (SANS).
Recent findings
Low gravity conditions and other aspects of spaceflight affect the eye detrimentally, causing SANS which is characterized by optic disc edema, choroidal thickening, cotton wool spots, and a hyperopic shift. SANS is probably caused by altered hemodynamic flows in the head and neck as well as mildly elevated intracranial and intraocular pressures. Carbon dioxide and other chemicals in space-craft may influence SANS as well. SANS may be ...

Endophthalmitis after cataract surgery: an update on recent advances
Purpose of review
Prevention and management of postcataract endophthalmitis remain quite relevant for anterior segment and vitreoretinal surgeons. Although the Endophthalmitis Vitrectomy Study, published in 1996, remains the only level 1 evidence for the management of postcataract endophthalmitis, recent advances have resulted in an evolution of practice patterns. The aim of this review is to summarize the literature regarding postcataract endophthalmitis with a focus on the last 18 months.
Recent findings
The IRIS registry indicates the rates of endophthalmitis are decreasing in the United States, and the outco...

Refractive enhancements for residual refractive error after cataract surgery
Purpose of review
Advances in cataract surgery have allowed surgeons to achieve superior refractive outcomes but have also led to higher patient expectations. Despite ever-evolving technology, residual refractive errors still occur. Postcataract refractive enhancements may be required to deliver satisfactory visual outcomes. This review aims to discuss the potential causes of residual refractive errors and the various enhancement modalities to correct them.
Recent findings
A thorough preoperative workup to detect and address underlying pathologic causes of impaired vision should be performed prior to enhancement...

Use of presbyopia-correcting intraocular lenses in patients with prior corneal refractive surgery
Purpose of review
Corneal refractive surgery has achieved spectacle-free vision for millions of patients, but this aging population is now developing cataracts. Many of these patients may wish to avoid reliance on glasses after cataract surgery. Presbyopia-correcting intraocular lenses (IOLs) offer a solution, but corneal changes after refractive surgery may compound higher order aberrations and dysphotopic symptoms associated with these IOLs. This review aims to discuss potential factors that could aid in determining suitable postkeratorefractive candidates for presbyopia-correcting IOLs.
Recent findings

A review of late intraocular lens opacifications
Purpose of review
Phacoemulsification cataract surgery is one of the most commonly performed surgical procedure worldwide. In the majority of cases, intraocular lenses (IOLs) are implanted. Due to the increasing life expectancy and the fact that cataract surgery is performed in earlier stages, the anticipated IOL duration in the eye has increased over the last decades. The aim of this study was to review the types and describe the characteristics of late intraocular lens opacifications.
Recent findings
Calcification was the most commonly reported type of opacification in hydrophilic IOLs; it usually negatively i...

Refractive outcomes and complications following angle supported, iris fixated, and posterior chamber phakic intraocular lenses bilensectomy
Purpose of review
The manuscript presents a review of published studies regarding the outcomes, causes, and complications of phakic intraocular lens (pIOLs) bilensectomy.
All pIOLs will be explanted at some point, therefore is important to know the visual and refractive outcomes following bilensectomy.
Recent findings
There are few publications about the outcomes following pIOL bilensectomy; in all of them, cataract remains the main cause of bilensectomy. Other causes are endothelial cell density loss and pupil ovalization. The mean time between pIOL implantation and bilensectomy is longer in eyes implanted w...

Flanged fixation: Yamane technique and its application
Purpose of review
To review variations of flanged intraocular lens fixation (Yamane technique) and their outcomes.
Recent findings
Sutureless intrascleral IOL fixation has become popular, and many techniques have been reported. Among them, the Yamane technique has been widely used in recent years, and there are many variations. However, there are no reports that systematically compare them.
Summary
There are variations of the Yamane technique, such as those used to create a scleral tunnel or to dock needles and haptics. Although few reports have directly compared each technique, small scleral wounds appea...

Handling regular and irregular astigmatism during cataract surgery
Purpose of review
There are several different approaches to handling regular and irregular astigmatism during cataract surgery, but still much debate on which solutions are most effective given unique patient circumstances. In this review, we examine recent literature and studies to highlight some of the most effective ways to plan preoperatively, manage regular and irregular astigmatism during cataract surgery, as well as managing postoperative complications.
Recent findings
Recent developments in technology have provided increased courses of action for astigmatism management during cataract surgery. Additional...

FOCUSED (Femtosecond Optimized Continuous Uncorrected Sight with EDOF and Diffractive Multifocal IOLs) - A Review
Purpose of review
The aim of this article is to review techniques to maximize all-distance uncorrected visual acuity and minimize photic phenomena after the implantation of multifocal and extended-depth of focus (EDOF) intraocular lenses (IOLs). This review examines the role of femtosecond laser-assisted cataract surgery (FLACS) in postoperative minimization of astigmatism and optimization of outcomes with multifocal and EDOF lenses.
Recent findings
By incorporating intraoperative and preoperative imaging, femtosecond platforms such as those that utilize iris or conjunctival vessel registration, can enable a pre...

History through the eyes of a pandemic
Purpose of review
This review provides a historic perspective of the impact that major pandemics have had on human and their relationship with ophthalmology. The novel coronavirus epidemic is also analyzed, highlighting the relevance of the eye as a possible source of transmission, infection, and prognosis for the disease.
Results
Smallpox is suspected to be present for more than 12 000 years. However, trachoma seems to be the first recorded ophthalmological infectious disease. The deadliest pandemics include the bubonic plague, smallpox, and Spanish flu. The CoVID-19 epidemic is still developing and measures need t...
