Background: Refractory corneal edema is the foremost reason for endothelial corneal transplantation (EK) in the world. Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSAEK) offer good clinical outcomes. However, human donor tissue is limited in availability and has a complex logistical chain.

Methods: The EndoArt (EyeYon Medical, Ness Ziona, Israel), an artificial endothelial replacement membrane designed to treat corneal edema, was implanted in 24 eyes of 24 patients with low-to-normal visual potential. We present the safety and efficacy results from a prospective, open-label, single-arm, multicenter study conducted over a 12-month period.
Purpose: To evaluate the feasibility of new adjustable intraocular lens (IOL) technology.
Methods: The foldable adjustable IOL consists of a nitinol mechanism placed in a haptic-optic cradle. Heating actuators on the nitinol mechanism with a continuous green laser achieve controlled movement of the mechanism and optic.
Purpose: To investigate visual and safety outcomes of AcrySof IQ PanOptix (model TFNT00), a trifocal, presbyopia-correcting intraocular lens (IOL), in patients of different ethnicities across multiple countries, based on a pooled analysis of six prospective multicenter studies.
Patients And Methods: This pooled analysis included adult patients from six prospective clinical studies performed across 56 centers worldwide. After cataract removal by phacoemulsification, all patients were implanted with TFNT00; follow-up duration varied from 3 to 12 months according to the studies' design.
Purpose: To compare standard and total corneal astigmatism measurements to the predicted pseudophakic (nontoric) refractive astigmatism in candidates for cataract surgery.
Design: A retrospective, cross-sectional study.
Methods: A single-center analysis of consecutive eyes measured with a swept-source optical coherence tomography biometer at a large tertiary medical center between February 2018 and June 2020.
Purpose: To assess visual results (including the Lapid-Kushlin defocus coefficient), and satisfaction, following the implantation of PanOptix® a trifocal intraocular lens.
Methods: Observational, retrospective cohort study. 130 eyes of 65 subjects with bilateral implantation were included.

Purpose: To validate a new methodology of intraocular lens (IOL) assessment using acuity reserve analysis via area under the curve (AUC) to assess intermediate vision.
Setting: Study 1 was conducted at 17 sites in Australia, Chile, and Europe. Study 2 was conducted at 15 sites in Australia, Brazil, and Europe.
Unlabelled: Disturbing binocular problems can be too complex to be treated in such a way that comfortable binocular single vision is restored. The grey filter contact lens could offer a safe and clinically useful way to help these patients.
Background: In unilateral acquired reduced visual performance or intractable diplopia the binocular performance often is less than the performance of the better eye, possibly leading to complaints of binocular visual functioning.
Purpose: To compare calculated corneal surgically induced astigmatism (SIA) by means of anterior-based keratometry (K) and total keratometry (TK) measurements made by 2 biometric devices.
Setting: Ophthalmology Department, Shaare Zedek Medical Center, Jerusalem, Israel.
Design: Retrospective, consecutive case series.
In this case series, we report the use of the black Artisan iris-claw intraocular lens (IOL) (Ophtec, The Netherlands) in 6 patients with various visually debilitating symptoms requesting occlusion of one eye. Between 2016 and 2019, 6 (5 female, 1 male) patients underwent implantation of the custom-made black Artisan iris-claw IOL after other management strategies had failed to relieve their symptoms. The black Artisan IOL is an opaque anterior chamber IOL that is fixated to the iris by enclavation.

Setting: Multicenter, 15 sites.
Design: Prospective, parallel-group, randomized, double-masked, postmarketing clinical study.
Purpose: To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas available on the American Society of Cataract and Refractive Surgery calculator in calculating multifocal IOL power in eyes with previous hyperopic corneal refractive laser surgery.
Design: Retrospective case series.
Setting: Amsterdam University Medical Center, University of Amsterdam, and Retina Total Eye Care, Driebergen, the Netherlands.
Purpose: To compare the accuracy of different intraocular lens (IOL) calculation formulas available on the American Society of Cataract and Refractive Surgery (ASCRS) post-refractive surgery IOL power calculator for the prediction of multifocal IOL power after previous corneal refractive laser surgery for myopia.
Methods: An analysis and comparison were performed of the accuracy of three methods using surgically induced change in refraction (ie, Masket, Modified Masket, and Barrett True-K formulas) and three methods using no previous data (ie, Shammas, Haigis-L, and Barrett True-K No History formulas). The average of all formulas was also analyzed and compared.
Purpose: To study straylight before and after posterior polar cataract removal.
Setting: Academic Medical Center, Amsterdam, the Netherlands.
Design: Prospective case series.
Purpose: To describe the outcomes in terms of the refraction and visual acuity of multifocal intraocular lens (IOL) implantation in patients with previous hyperopic corneal refractive laser surgery.
Setting: Academic Medical Center, University of Amsterdam, Amsterdam, and Retina Total Eye Care, Driebergen, the Netherlands.
Design: Retrospective case series.
Purpose: To describe the refraction and visual acuity outcomes of multifocal intraocular lens (IOL) implantation in patients with previous corneal refractive laser surgery for myopia.
Setting: Academic Medical Center, University of Amsterdam, Amsterdam, and Retina Total Eye Care, Driebergen, the Netherlands.
Design: Retrospective cohort study.
Purpose: To report the results of long-term topical treatment with bevacizumab (Avastin) 5 mg/mL eyedrops in a case of aniridia-related neovacularization of the cornea.
Methods: Interventional case report. A female patient with aniridia had a decrease in the best corrected visual acuity from 0.
Objectives: To study the effects of corneal scars and the treatment of these scars with rigid gas-permeable (RGP) contact lenses on quality of vision including straylight. Visual effects were related to scar characteristics such as size and grade.
Methods: Straylight and best-corrected visual acuity were measured in 23 patients with corneal scars during and after RGP contact lens wear.
