In a certain kind of eye surgery, the human eyeball is deformed sustainably by the application of an elastic band. This article presents a mathematical model for the mechanics of the combined eye/band structure along with an algorithm to compute the model solutions. These predict the immediate and the lasting indentation of the eyeball. The model is derived from basic physical principles by min...

Children with Goldenhar syndrome are known to present airway management challenges for the anesthesiologist. We present the case of a 10-year-old child with Goldenhar syndrome, in whom a flexible Laryngeal Mask Airway (Intavent Orthofix, Ltd, Maidenhead, UK) was successfully used for eye surgery.

PURPOSE To describe the demographic pattern of congenital cataract surgery at a referral ophthalmology center in Iran and to evaluate any possible difference between the genders. METHODS Subjects aged 15 years or less scheduled for cataract surgery were enrolled in this cross-sectional study. Data was retrieved from the electronic medical records according to the ICD-10 coding system. Age and...

Extending life expectancy is a human achievement. It does however entail problems. Ophthalmic treatments are widely recognized as having a low risk of general complications. A classic example is cataract surgery, considered to be one of the safest and most frequently performed surgical procedures in the world. However, advanced age brings with it risks that should be considered before surgery. ...

Products from Nature have a long and intriguing history of providing man with useful materials for his daily life. None is more important than the medium-chain fats found in mother's milk. Mention was made in Sanskrit medicine that freshly expressed human milk was routinely used as an "antibiotic" after eye surgery. Research in our laboratory discovered that the most active lipid ingredient (mo...

The use of performance enhancing drugs among elite athletes has been in the headlines recently, particularly with Lance Armstrong's fall from grace and his admission about widespread doping. Many argue that the use of drugs confers an unfair advantage and is ultimately dangerous to the health of the athletes. Others, like Professor Shuster, argue that the use of drugs is no different from other...

Low-frequency (LF) ultrasound (20-100 kHz) has a diverse set of industrial and medical applications. In fact, high power industrial applications of ultrasound mainly occupy this frequency range. This range is also used for various therapeutic medical applications including sonophoresis (ultrasonic transdermal drug delivery), dentistry, eye surgery, body contouring, the breaking of kidney stones...

INTRODUCTION Anaesthesia procedures for surgical interventions in patients with amyotrophic lateral sclerosis (ALS) are not commonly found in clinical practice, and often have special considerations that must be taken into account in treatment planning. As a result, these procedures are rarely subject to publication, rendering it difficult for the anaesthesiologists to find useful and reliable ...

Aims. (1) To assess the efficacy and safety of pediatric office-based sedation for ophthalmologic procedures using a pediatric sedation service model. (2) To assess the reduction in hospital charges of this model of care delivery compared to the operating room (OR) setting for similar procedures. Background. Sedation is used to facilitate pediatric procedures and to immobilize patients for imag...

In this paper we propose a real-time solution to localize the surgical instruments in an eye surgery simulator, EyeSi. The hardware consists of three synchronized cameras that capture the movements of the instruments, and an FPGA card for grabbing and preprocessing the images. The surgical instruments are localized using the method of Hough transform combined with the technique of stereo vision...
