iris and the dilator muscles. However these two aspects of the eye are not involved in laser eye surgery and will not be discussed in reference. The focusing of objects and images is very much part of laser eye surgery. In order for a clear visual image to be formed the image must come to a point on the retina. Light rays do not
Abstract According to the report for the 2012 National Health Interview Survey, at least 1.5 million Americans weakened their vision due to use of technology. However, thanks to advanced technology and innovation people can choose between glasses and contacts as a therapy for improving their eyesight. Contact lenses have become the fastest progressing medical devices in optometry and have seen a number of significant improvements and developments since its existence (Schaeffer, 2011). According to
Digital radiography (DR) is a revolutionary invention in radiography. With this technology, no cassette is needed for an x-ray examination meaning that there is no need to reload films or to erase imaging plate in every examination. This is a distinctive feature which conventional radiography and computed radiography (CR) do not have. DR was first introduced in 1996 (Carroll, 2011). Miniature electronic x-ray detectors are used as the image receptor. The detectors enable the direct capture of the
spectacle or contact lenses. So in last years the refractive surgery increased in patients dissatisfied with spectacles and contact lenses either due to quality of vision, cosmetic appearance or difficulties in contact lenses wearing and its complications. corneal surgeries like corneal ablation ( photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis LASIK) and different types of phakic intraocular lens (PIOL) implantation either in the anterior or posterior chamber and the anterior
The Visian Implantable Collamer Lens (ICL, STAAR Surgical, Nidau, Switzerland), a posterior chamber phakic intraocular lens (IOL), has been widely used and accepted for the correction of high myopia [1]. It has been reported to be safe, effective and reversible approach, but patients must be aware of possible complications, such as lens opacification, endothelial cell loss, increased intraocular pressure (IOP), inflammation and others[2, 3]. The anterior segment parameters are vital to choose
with open angle glaucoma in the world and it is estimated that in 2020, these numbers will increase to 59 million in the world with 3.5 million cases in the United States.2 Glaucoma can lead to irreversible blindness in 12.3% of the cases.2 Because vision loss in glaucoma is irreversible, early diagnosis and treatment of glaucoma is critical for decreasing blindness worldwide.3 Since studies have shown that optic nerve changes and retinal nerve fiber layer (RNFL) thinning can precede visual field loss
have been traditionally digitized using scanners and read with the help of optical character recognition (OCR). Recent technical advances in digital cameras have led the OCR community to consider using them instead of scanners for document capture. Compared with the scanner, the digital camera is quite easier to use, being able to capture images from any viewpoint. Cameras can be easily integrated with portable computing devices such as PDAs, cell phones, or media players. Together, these factors contribute
