Flaporhexis, a technique to make the femtosecond laser corneal flap was developed primarily to reduce the mechanical trauma associated with separating the corneal tissue by taking advantage of the cornea’s natural anatomy and was first described in a peer reviewed artice in 2008. The anterior part of the cornea tends to be stronger, thereby allowin...

To evaluate the safety, stability, and efficacy of the first clinical cases of epithelial laser in situ keratomileusis (epi-LASIK) performed using a 1000 Hz excimer laser system. Klinikum Rechts der Isar, Munich, Germany. The epi-LASIK procedure was performed using an EpiLift microkeratome and a WaveLight Concept System 1000 laser. Preoperatively a...

OBJECTIVE: The aim of this study was to evaluate the cut quality and the cellular damage when using a new 200 kHz femtosecond laser. METHODS: 20 porcine eyes and 3 human eyes, not suitable for transplantation, were used for this study. The WaveLight UltraFlap femtosecond laser was used for flap creation. The surface of the cornea, the structure and...

To evaluate possible factors responsible for the difference between predicted and measured parameters during 100 microm flap creation with a femtosecond laser (IntraLase FS30) using online optical coherence pachymetry (OCP). AugenVersorgungsZentrum, Weilheim, and the Technical University of Munich, Munich, Germany. In this nonrandomized prospective...

Purporse: "Flaporhexis" and "Hinge Opening" are two different methods of making the femtosecond laser flap. This contralateral eye study analyses the intraoperative occurrences and complications of both methods. The safety and efficacy of this series is analysed, side effects are reported and recommendations given. Methodes: "Flaporhexis" and "Hing...

A 30-year-old male presented with signs of ocular inflammation and motility disturbances in an early stage of HIV infection. The provisional diagnosis of an ocular myositis was confirmed by orbital echograms. A general check up revealed positive anti-smooth-muscle antibodies and antinuclear antibodies as well as a raised erythrocyte sedimentation r...

Acute retinal necrosis (ARN) is increasingly being observed among patients with HIV infection. Varicella-zoster virus (VZV) and herpes simplex virus (HSV) are recognized as being the etiologic agents in this syndrome. Among the 538 patients with HIV infection (261 of these with AIDS), who were followed up in our department between 1985 and 1990, we...

Peripheral neuropathy is increasingly recognized as a complication of the Acquired Immune Deficiency Syndrome (AIDS) and AIDS-related complex (ARC), but the varied clinical features have been incompletely described. Thirty homosexual men with peripheral neuropathy were evaluated in this study. Twenty-one had ARC and nine had AIDS. Four distinct cli...

Peripheral neuropathy is increasingly recognized in patients with AIDS as well as AIDS-related complex (ARC). Thirty homosexual men with polyneuropathy were evaluated in this study. Twenty-one had ARC and nine had AIDS. We observed three distinct clinical syndromes: distal sensorimotor polyneuropathy, chronic inflammatory demyelinating polyrediculo...

The role of therapeutic apheresis was assessed in a number of clinical syndromes associated with the acquired immune deficiency syndrome (AIDS) and AIDS-related complex (ARC). Four groups of patients were studied: AIDS with opportunistic infections, AIDS with Kaposi’s sarcoma, AIDS/ARC patients with peripheral neuropathy and a patient with AIDS-rel...
