In this video, Professor Dan Reinstein performs a bilateral LASIK procedure filmed in real-time to demonstrate the full 8 and-a-half minute procedure from multiple angles. The superior design and experience of the Carl Zeiss Meditec Visumax femtosecond Laser for flap creation is seen, where the patient is only in contact with the device for about 30 seconds with extremely low contract force such that the patient feels effectively nothing, there are no red splodges (subconjunctival haemorages) left behind. From the surgeons' standpoint there is no device that is easier to use or faster for LASIK flap creation. The Carl Zeiss Meditec MEL80 excimer laser portion of the procedure is seamlessly integrated and incorporates all the features that make clinical outcomes so reproducible including the unique cone-for-controlled-atmosphere (CCA) and high efficiency, high sensitivity calibration test which can be performed for each individual patient to compensate for minor changes in energy that occur with excimer laser devices during the course of a day.

Achalasia is a neurogenic esophageal motility disorder characterized by impaired esophageal peristalsis and a lack of lower esophageal sphincter relaxation during swallowing. Symptoms are slowly progressive dysphagia, usually to both liquids and solids, and regurgitation of undigested food. Evaluation typically includes manometry, barium swallow, and endoscopy. Treatments include dilation, chemical denervation, surgical myotomy, and peroral endoscopic myotomy.

Thoracic outlet syndrome affects the space between the collarbone and first rib (thoracic outlet). Common causes include trauma, repetitive injuries, pregnancy, and anatomical defects, such as having an extra rib. Symptoms include pain in the shoulders and neck and numbness, weakness, and coldness in the fingers. Treatment involves physical therapy and pain relief. In rare cases, surgery may be needed to relieve the compression.

What is Laparoscopic Surgery:
Laparoscopic surgery describes procedures performed using one or multiple small incisions in the abdominal wall in contrast to the larger, normally singular incision of laparotomy. The technique is based around principles of minimally invasive surgery (or minimal access surgery): a large group of modern surgical procedures carried out by entering the body with the smallest possible damage to tissues. In abdominopelvic surgery, minimally invasive surgery is generally treated as synonymous with laparoscopic surgery as are procedures not technically within the peritoneal cavity, such as totally extraperitoneal hernia repair, or extending beyond the abdomen, such as thoraco-laparoscopic esophagectomy. The term laparoscopy is sometimes used interchangeably, although this is often reserved to describe a visual examination of the peritoneal cavity or the purely scopic component of a laparoscopic procedure. The colloquial keyhole surgery is common in non-medical usage.

Surgical Objective of Laparoscopic Surgery:
The objective of a laparoscopic approach is to minimize surgical trauma when operating on abdominal or pelvic structures. When correctly indicated and performed, this can result in smaller scars, reduced postoperative morbidity, shorter inpatient durations, and a faster return to normal activity. For a number of abdominopelvic procedures, a laparoscopic approach is now generally considered to be the gold-standard treatment option.

Developments of Laparoscopic Surgery:
Following a number of smaller-scale applications of minimally invasive techniques to abdominopelvic surgery, laparoscopic surgery became a major part of general surgical practice with the introduction of laparoscopic cholecystectomy in the 1980s and the subsequent pioneering of endoscopic camera technology. This led to the widespread adoption of the technique by the early- to mid-1990s. The portfolio of procedures that can be performed laparoscopically has rapidly expanded with improvements in instruments, imaging, techniques and training — forming a central component of modern surgical practice and cross-specialty curricula [2]. Techniques such as laparoscopically assisted surgery and hand-assisted laparoscopic surgery have allowed the application of laparoscopic techniques to a greater variety of pathology. Single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and minilaparoscopy-assisted natural orifice surgery continue to push forward the applications of minimally invasive abdominopelvic techniques; however, the widespread practice and specific indications for these remain to be fully established. More recently, robotic surgery has been able to build on laparoscopic principles through developments in visualization, ergonomics, and instrumentation.

Esophageal manometry is a test used to measure the function of the lower esophageal sphincter (the valve that prevents reflux of gastric acid into the esophagus) and the muscles of the esophagus (see diagram). This test will tell your doctor if your esophagus is able to move food to your stomach normally.

Giant cell tumour is a locally aggressive primary bone tumour, located eccentrically in the metaphysis and epiphysis of a long bone. It commonly affects distal end of Femur, proximal end of Tibia and distal end of Radius. It is occasionally reported in small bones of hand and foot[1], spine[2] and pelvis[3]. Though it occurs in 20 - 35 year old individuals commonly, it can also be seen in children as young as 2 years[4] and also in older individuals

The headache, lethargy, and neck stiffness suggest subarachnoid hemorrhage secondary to rupture of a mycotic aneurysm. Mycotic or infected arterial aneurysms can develop due to metastatic infection from IE, with septic embolization and localized vessel wall destruction in the cerebral (or systemic) circulation. Intracerebral mycotic aneurysms can present as an expanding mass with focal neurologic findings or may not be apparent until aneurysm rupture with stroke or subarachnoid hemorrhage. The diagnosis of mycotic cerebral aneurysm can usually be confirmed with computed tomography angiography. Management includes broad-spectrum antibiotics (tailored to blood culture results) and surgical intervention (open or endovascular).

Tuberous breast deformity is a congenital breast anomaly that becomes manifest at the time of puberty and breast development. The three components of tubular deformity usually include, pseudoherniation of breast tissue into the nipple areolar complex, poorly defined inframammary fold and flattening of the lower pole of the breast which leads to a conical tubular shape.

Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system). In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause the nerves themselves to deteriorate or become permanently damaged. Signs and symptoms of MS vary widely and depend on the amount of nerve damage and which nerves are affected. Some people with severe MS may lose the ability to walk independently or at all, while others may experience long periods of remission without any new symptoms. There's no cure for multiple sclerosis. However, treatments can help speed recovery from attacks, modify the course of the disease and manage symptoms
