Background: To evaluate the agreement in intraocular pressure (IOP) measurements by Ocular Response Analyzer (ORA) and Tono-Pen XL (TXL) with the Goldmann Applanation Tonometer (GAT) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (CCT) >600 µ. Methods: Thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...

Medical practice and life sciences take full advantage of progress in engineering disciplines, in particular the computer assisted placement technique in hip surgery. This paper describes the three dimensional model reconstruction of human femur from MRI images. The developed program enables to obtain digital shape of 3D femur recognized by all CAD software and allows an accurate placement of t...

Heel pain is a very common foot disease that may cause significant discomfort and disability. Biomechanic factors are the most etiology can induce mild to moderate chronic heel pain. Common conditions related with includes: plantar fasciitis, calcaneal spur, sever's disease, Achilles tendinopathy, bursitis. Location of guide proper diagnosis for particular variety This review presents current s...

BACKGROUND The understanding of the external mechanics of Pilates exercises and the biomechanics of the joints may guide the prescription of rehabilitation exercises. OBJECTIVES To evaluate the resistance torque (Γ(R)) during hip extension (HE) exercises performed on the Pilates Cadillac. To perform a biomechanic analysis of the Γ(R) and the weighted mean moment arm (WMMA) in order to calcula...

abstract background: keratoconus is a bilateral corneal disease, which one way to cure it is to transplant. the transplantation may be rejected by recipient's immune system, which leads to failure of the graft. this study aimed to analysis the factors affecting bilateral corneal graft rejection based on copula function. methods: a sample of bilateral graft rejection times was assessed. since co...

Objective- This study was performed to evaluate and compare grossly and pathologically two surgical techniques of amniotic membrane patching on experimental corneal alkali burn in dogs.   Design- Experimental study.   Animals- Fifteen healthy dogs   Procedures- The central corneas of the dogs were inflicted by applying a round filter paper, 6.0 mm in diameter, soaked in 1 N NaOH for 60 sec. ...
