A 74-year-old woman had uneventful phacoemulsification with implantation of a single-piece hydrophobic acrylic intraocular lens (IOL) (SA30AL) in her left eye. Two weeks after the surgery, the patient presented for ophthalmological consultation reporting pseudophakic dysphotopsia, which she had subjectively noted since surgery. Explantation/exchange of the IOL was performed 3 months after the surgery. The IOL was strongly attached to the capsule, which was fibrotic and contracted; explantation of the capsular bag complex in toto was done. To our knowledge, this is the first case of explantation of this IOL design with clinicopathological correlation.

Introduction: We conducted an evaluation of capsular bag performance of the Clareon CNA0T0 intraocular lens (IOL), focusing on postoperative anterior chamber depth (ACD), IOL tilt, and IOL decentration.
Methods: Inclusion criteria were bilateral age-related cataract and the ability to provide informed consent. Exclusion criteria were prior surgeries, combined surgeries, and conditions posing a risk for postoperative capsular bag instability.

Introduction: The geometry of an intraocular lens (IOL), the design of the haptics, and the optic-haptic junction play a role in initial and long-term visual outcome after cataract surgery. Knowledge of the behavior of an implant in the capsular bag and under compression is of major importance. Our laboratory experiment analyzed in-depth the geometry of acrylic, single-piece, premium, presbyopia-correcting intraocular lenses and changes in haptic-capsular bag relationships according to capsular bag size using a range of compression well diameters.

Objective: Successful intraocular lens (IOL) placement in cataract surgery is synonymous with the IOL being placed in the capsular bag. When the capsular bag is violated, the ciliary sulcus becomes an option to approximate an in- the-bag position. Studies report that single-piece foldable acrylic (SPA) IOLs are a poor choice for the sulcus.

Purpose: The IC-8® Apthera™ (AcuFocus Inc.™, Irvine, California, USA) is the first small aperture intraocular lens (IOL) to receive FDA approval for presbyopia correction in the summer of 2022. It is a single-piece hydrophobic acrylic monofocal lens, which is placed in the capsular bag.

From the Department of Ophthalmology, Medical University of Vienna, Vienna, Austria.
Purpose: To compare intraindividually the incidence and intensity of posterior capsule opacification (PCO) and Nd:YAG capsulotomy rates between 2 similar open-loop single-piece hydrophobic acrylic intraocular lenses (IOLs) differing slightly in their particular material, optic surface, and sharp posterior edge design over a period of 3 years.
Setting: Department of Ophthalmology, Medical University Vienna, Vienna, Austria.
Design: Randomized, prospective, patient-masked and examiner-masked clinical trial with intraindividual comparison.
