Purpose: To compare variance of manifest refraction (MR) measurement and variance of refractive outcomes after keratorefractive lenticule extraction (KLEx) in the same cohort.
Methods: This was a retrospective study of consecutive patients attending at least three preoperative refractions before undergoing KLEx. All manifest refractions were performed according to a standard protocol.
Purpose: To evaluate the impact of refractive couplings in myopia and myopic astigmatism with two different keratorefractive lenticule extraction (KLEx) systems.
Methods: This was a retrospective evaluation of refractive outcomes with two different lasers studying 2,841 eyes undergoing small incision lenticule extraction (SMILE) (VisuMax 500; Carl Zeiss Meditec) and 2,528 eyes undergoing SmartSight (ATOS; SCHWIND eye-tech-solutions GmbH). Coupling effects (derived from the ratio between partial slopes) were determined for sphere and cylinder and for spherical equivalent, cardinal, and oblique astigmatism separately.
Purpose: To investigate the feasibility and safety of a new small-aperture device, which is implanted on top of the intraocular lens.
Methods: Regular cataract surgery was performed in both eyes in 7 patients. In the non-dominant eye, a small-aperture device (VisionXtender; Morcher) was additionally implanted into the capsular bag at the end of the surgery.
Introduction: One of the most common causes of vision loss in the elderly population worldwide is age-related macular degeneration (AMD). Subsequently, the number of people affected by AMD is estimated to reach approximately 288 million by the year 2040. The aim of this study was to develop an model that simulates various aspects of the complex AMD pathogenesis.
