Reimbursement of radiotherapy in Germany.
2017
Reimbursement of radiotherapy in Germany is mainly based on a certain fixed fee for treatment planning and patient set up in addition to payment per fraction. This applies to outpatient care for patients with public health insurance or private health insurance. Payment per fraction has a considerable influence on reimbursement of inpatients as well. The advantage of payment per fraction is the simplicity and transparency. The disadvantage is an inadequate reimbursement for new treatment modalities like hypofractionation or stereotactic body radiotherapy.
Impact of the pupil size – central optical zone diameter relationship on visual performance in aspheric multifocal contact lenses
2020
Abstract Purpose To determine the impact of different central optical zone diameters (COZDs), obtained from pupil size, on the visual performance of presbyopic subjects fitted with centre-distance simultaneous-image multifocal contact lenses (SIMCLs). Methods Thirty-two presbyopic volunteers, between 45–58 years of age, participated in this prospective, controlled, double-blind study. Subjects were fitted with 5 centre-distance SIMCLs of variable COZD, determined from the measurement of pupil size under photopic light conditions and corresponding to 60, 70, 80, 90 and 100 % of pupil diameter. Subjects visual performance was evaluated through the measurement of distance, intermediate and nea…
Benefits and Side Effects of Bandage Soft Contact Lens Application after LASIK
2005
Purpose To evaluate benefits and side effects of bandage soft contact lens (BSCL) insertion after LASIK in relation to patients’ characteristics. Design Prospective, randomized, bicenter comparative investigational trial. Participants One hundred patients (200 eyes) with myopia and/or myopic astigmatism. Methods Each patient underwent consecutive (Marburg, Germany) or simultaneous (Mainz, Germany) bilateral LASIK. At the end of the procedure, the first treated eye received a drop of ofloxacin and dexamethasone, patch, and transparent protective shield for 2 to 4 hours. The fellow eye received in addition a BSCL, soaked in the same eyedrops for 20 to 24 hours. Main Outcome Measures Schirmer …

were those plausibly associated with the procedure and severe enough for the patient to seek medical attention. We compared the proportion of patients with adverse events associated with gastrointestinal endoscopy identified with direct patient contact to the proportion identified through our current infrastructure using the chi-square statistic. Results: During the study period, 11,710 endoscopic procedures were performed on 9,683 patients. Our study personnel made 3205 calls over a three month period and ultimately made contact with 1999 (17%; 84.5% of those called) patients. 28 (1.4%) adverse events were identified through direct patient contact. Our adverse event tracking infrastructure…
Effects of a Vibro-Tactile P300 Based Brain-Computer Interface on the Coma Recovery Scale-Revised in Patients With Disorders of Consciousness
2020
Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor and cognitive disabilities. Recent research has shown that non-invasive brain-computer interface (BCI) technology could help assess these patients’ cognitive functions and command following abilities. 20 DOC patients participated in the study and performed 10 vibro-tactile P300 BCI sessions over 10 days with 8–12 runs each day. Vibrotactile tactors were placed on the each patient’s left and right wrists and one foot. Patients were instructed, via earbuds, to concentrate and silently count vibrotactile pulses on either their left or right wrist that presented a target stimulus and to ignore …
Lens implant selection with absence of capsular support.
2001
If contact lens or spectacle correction is not viable, little debate exists that the secondary placement of an intra-ocular lens (IOL) is the method of choice in the absence of capsular support. The choice of IOL mainly depends on the preoperative status of the eye (eg, aphakia in children) and the selected location for the implant. Theoretically, there are several IOL implantation approaches in cases without capsular support: an angle-supported anterior chamber (AC) IOL, an iris-fixated ACIOL, an iris-sutured or iris-fixated posterior chamber (PC) IOL and a transsclerally sutured PCIOL. No consensus exists, however, on the indications as well as on the relative safety and efficacy of these…
