A Randomized Study of the Impact of a Corneal Pre-Cut During Cataract Surgery on Wound Architecture and Corneal Astigmatism.

Introduction: The aim of the current study was to assess the effect of a 600-µm corneal pre-cut on wound architecture and its impact on surgically induced astigmatism. The images were acquired intraoperatively and postoperatively with high-resolution spectral-domain optical coherence tomography (SD-OCT).

Methods: This study included patients scheduled for cataract surgery.

Benefit of psychiatric evaluation on anxiety in patients with Charles Bonnet syndrome.

Objective: Charles Bonnet syndrome (CBS) is defined as an occurrence of visual hallucinations (VHs) in the absence of any psychiatric/neurological disorder. Significantly reduced vision due to age-related macular degeneration (AMD), cataract or glaucoma is the most common cause for CBS. Aim of this randomized controlled study was to assess whether additional treatment by a psychiatrist is beneficial for patients with CBS.

Intraoperative Optical Coherence Tomography-Guided Membrane Peeling for Surgery of Macular Pucker: Advantages and Limitations.

Purpose: Epiretinal membranes (ERMs) are a disorder leading to progressive vision loss and metamorphopsia. The gold standard in therapy is vitrectomy with membrane peeling. The aim of this study was to assess whether the use of intraoperative optical coherence tomography (iOCT), which allows tomographic visualization of the membrane during peeling, enables peeling without staining.

Enhanced Penetration for Axial Length Measurement of Eyes with Dense Cataracts Using Swept Source Optical Coherence Tomography: A Consecutive Observational Study.

Introduction: The aim of this study was to find cases in which the axial eye length could not be measured with partial coherence interferometry (PCI) technology and to assess if it could be measured using swept source optical coherence tomography (ss-OCT) technology.

Methods: All patients were measured at their pre-assessment visit 1 week prior to cataract surgery using conventional optical biometry (PCI technology, IOLMaster 500, Carl Zeiss Meditec AG, Jena, Germany). Patients in whom one or both eyes could not be measured using PCI technology were invited to participate in the study and to be measured with the ss-OCT (IOL Master 700, Carl Zeiss Meditec AG, Jena, Germany) device.
