An underlying diagnosis of keratoconus (KC) can complicate cataract surgery. In this study, the results of a focused review of the literature pertaining to cataract surgery in patients with KC are detailed. Topics essential for the appropriate management of this patient population are discussed. First, the individual and shared epidemiology and pathophysiology of cataract and KC are reviewed. Then, the theory and approach to intraocular lens power calculation are discussed, highlighting particularities and pitfalls of this exercise when performed in patients with KC. Finally, several special-although not uncommon-management scenarios and questions are addressed, such as surgical planning in cases where corneal stabilization or tissue replacement interventions are also necessitated.

Background: Constituting ~0.5% of all NHS cataract operations, national provision of immediately sequential bilateral cataract surgery (ISBCS) is limited. Combining offering ISBCS within a novel one-stop see-and-treat (S&T) cataract pathway would offer patients the opportunity for two cataract operations in a single hospital visit.

Photic phenomena are more pronounced in presbyopia-corrected than in monofocal intraocular lens (IOL), causing dissatisfaction after cataract surgery. Photic Phenomena Test (PPT) quantifies photic phenomena in eyes with two types of presbyopia-corrected IOL. We examined the relationship between preoperative eye shape and pupil diameter.

A lensless compact arrangement based on digital in-line holography under Gabor's regime is proposed as a novel contactless method to assess the profile of multifocal intraocular lenses (MIOLs) which are conformed by several diffractive rings. Diffractive MIOLs are a widely adopted ophthalmologic option for the correction of presbyopia in patients undergoing cataract surgery. The MIOL optical design might introduce non-negligible optical performance differences between lenses as well as the introduction of undesirable photic phenomena (such as halos and glare) affecting the vision of users.

Objective: This study investigates the refractive accuracy of eight intraocular lens (IOL) power calculation formulas in patients with postoperative refractive surprise after phacoemulsification. It aims to determine if a different formula could result in better refractive outcomes in these eyes.
Methods And Analysis: We retrospectively reviewed consecutive patients undergoing uncomplicated phacoemulsification as a sole procedure between March 2007 and September 2020 at the University of Washington by glaucoma subspecialists as part of a study investigating cataract surgery in normal eyes.

Cataract surgery is the most frequently performed surgery worldwide. Although it is an effective surgical treatment option for improving patients' visual acuity, various complications can occur postoperatively. One such complication is the presence of retained lens material in the anterior chamber, which can lead to intraocular inflammation, increased intraocular pressure, corneal edema, and endothelial cell loss.
