Background: The visual performance and the optical quality of a segmental refractive extended depth-of-focus (EDoF) intraocular lens (IOL) were evaluated in a prospective, single-arm, single-center study.
Methods: A total of 20 patients (40 eyes) after bilateral implantation of the refractive segmental EDoF Acunex Vario AN6V were included. Assessment procedure: refraction outcome, monocular and binocular uncorrected (UCVA) and distance-corrected visual acuity (DCVA), defocus curve, contrast sensitivity (CS), higher-order aberrations (HOAs) and patient satisfaction were evaluated 1 and 3 months after surgery.
Malignant masses of the orbit include a large variety of neoplasms of epithelial or mesenchymal origin. The treatment of orbital malignancies is an essential interdisciplinary field of medicine that integrates ENT medicine, facial surgery, plastic surgery, neurosurgery, oncology and radiology.The main symptom of malignant orbital masses is the exophthalmos.

Setting: Department of Ophthalmology, Charité - Universitätsmedizin Berlin, Germany.
Design: Prospective, monocentric, controlled, non-randomized, two-armed study.
Purpose: To evaluate visual performance and optical quality of an extended depth-of-focus intraocular lens (EDoF IOL) compared with a monofocal aspheric IOL.
Setting: Department of Ophthalmology, Charité-Medical University Berlin, Germany.
Design: Prospective case series.
Purpose: To compare and evaluate corneal higher-order aberrations (c-HOA) between conventional manual phacoemulsification (Phaco), femtosecond laser-assisted cataract surgery (FLACS), and femtosecond laser-assisted cataract surgery with astigmatic keratotomy (FSAK).
Methods: In this retrospective single center study, 53 healthy individuals with cataract (73 eyes) underwent phacoemulsification with implantation of an intraocular lens. Three groups were formed: group A, Phaco ( = 27 eyes of 21 patients); group B, FLACS ( = 25 eyes of 15 patients); group C, FSAK ( = 21 eyes of 17 patients).
Background: Conjunctival defects can be repaired with several mucosal tissues. The simplicity of harvesting oral mucosa and its wide availability makes it the preferred graft tissue for all indications requiring mucosal grafting. Through analysing the postsurgical outcomes and rate of revisions, this study explores the suitability of oral mucosa grafts, depending on the initial diagnosis.

Methods: A retrospective chart review of all patients presenting to the department of ophthalmology of Charité-University Medicine Berlin during a 7-day period around New Year's Eve in the years 2014-2017 was performed. Patients with ocular complaints and injuries caused by fireworks were included.
Benign orbital neoplasms comprise a wide spectrum of different entities. The origin of the tumours can be epithelial or mesenchymal. Epithelial neoplasms of the orbit originate from the lacrimal gland.

Methods And Analysis: A manual descemetorhexis (DR) of 8 mm diameter was compared with a femtosecond laser-assisted DR of the same diameter (femto-DR) in 22 pseudophakic patients requiring DMEK.
Purpose: The purpose of this study was to assess the clinical outcome after a bilateral implantation of an extended depth of focus intraocular lens in comparison to a monofocal intraocular lens.
Setting: Department of Ophthalmology, Charité-Medical University Berlin, Germany.
Patients And Methods: A total of 60 eyes of 30 patients were enrolled in this prospective, single-center study.
Purpose: To analyze the impact of different incision sizes for phacoemulsification on corneal higher-order aberrations (HOA).
Methods: Patients seeking cataract surgery were randomly assigned to one of the following groups: 1.4 mm with biaxial microincision phacoemulsification (25 eyes), 1.
Purpose: To explore the feasibility of femtosecond laser-assisted descemetorhexis (DR) to facilitate Descemet membrane endothelial keratoplasty (DMEK) surgery.
Methods: Six pseudophakic patients suffering from Fuchs' endothelial dystrophy underwent femtosecond laser-assisted DMEK surgery. DR was performed using the LenSx femtosecond laser, followed by manual removal of the Descemet membrane.
Purpose: To evaluate the effect of long-term chloroquine intake on the multifocal electroretinogram (mfERG) in female patients with and without maculopathy.
Methods: Retrospective analysis of the mfERGs recorded in three different groups: (1) patients with bilateral maculopathy having taken chloroquine, (2) patients without maculopathy having taken chloroquine, and (3) healthy control subjects (age-matched to group 2) who never took chloroquine. MfERGs of each group were averaged, and the data of each patient group were compared to the control group.
Purpose: The purpose of this study was to analyze the clinical outcome and higher-order aberrations (HOAs) after 1.4-mm biaxial microincision cataract surgery (B-MICS) and implantation of a new aspheric intraocular lens (IOL).
Material And Methods: A total of 157 eyes of 106 patients were enrolled in this prospective, single-center study.
Purpose: To analyze the dependence between corneal endothelial cell loss by Aqualase® cataract surgery and the nuclear opalescence grade of the lens.
Patients And Methods: A total of 100 eyes of 92 patients were enrolled in this prospective, single-center study. Patients were randomly assigned to the Aqualase (50 eyes) or the phacoemulsification group (50 eyes).
Purpose: To evaluate the indications, visual outcomes, and complication rate after posterior implantation of an iris-claw aphakic intraocular lens (IOL) in subluxated lenses due to Marfan syndrome.
Methods: Eyes without adequate capsular support had posterior chamber iris-claw aphakic IOL implantation between 2006 and 2012.
Results: This retrospective cohort study comprised 13 eyes of 10 patients (7 female, 3 male; mean age ± standard deviation, 34.
Purpose: To evaluate the indications, visual outcomes, and complication rate after posterior implantation of an iris-claw aphakic intraocular lens (IOL) in children.
Design: Noncomparative retrospective cohort study.
Methods: setting: Institutional practice.
Purpose: The aim of the study was to determine the influence of axial length (AL) and anterior chamber depth (ACD) on the rotational stability of a toric intraocular lens (IOL).
Methods: In this retrospective study, 40 eyes of 40 patients were included. All patients underwent phacoemulsification and had AcrySof toric IOL implantations.
