Cataract surgery is currently the most common and well-established ophthalmic sur-gical procedure in the world. This procedure involves the extracapsular extraction of the natural opaque lens fibers and implantation of an intraocular lens (IOL), which restores good vision. (1-2)
Posterior capsule opacification (PCO) is the most common complication following phacoemulsification and intraocular lens (IOL) implantation. (3) PCO is formed from lens epithelial cell migration from the equatorial area or from dislodged cortical fibers toward the visual axis. (4-5)
Various options have been described for the treatment of PCO. Primary posterior con-tinuous curvilinear capsulorhexis (PPCC) combined with phacoemulsification is a surgical technique to prevent posterior capsule opacification after cataract surgery in adults. However, neodymium:yttrium aluminum garnet (Nd:YAG) laser capsulotomy …show more content…
However, Nd: YAG laser capsulotomy is associated with retinal detachment, retinal tears, cys-toid macular edema, elevation of intraocular pressure, damage to intraocular lens, in-traocular inflammation, and macular hole.(8-9)
Due to the high incidence of PCO after cataract surgery and the potential complica-tions of Nd:YAG laser capsulotomy, studies for preventing PCO have increased. In these studies, several factors such as different optic material, the edge design of the optic and capsular bending ring implantation have been associated with a low rate of PCO. (10-11)
Posterior capsulorhexis was introduced initially for posterior capsule opacities or tears in adults, its use subsequently extended to include clear intact capsules, uveitic cataracts and paediatric patients.(12) Recently, primary posterior curvilinear capsulorhexis (PPCC) has been proposed to prevent PCO in adults based on the theory that removing the scaffold for the migration of lens epithelial cells will provide a permanently clear optical zone.

...DO1-136-I ARAVIND EYE HEALTH CARE OPERATIONS Original written by professor Ángel Díaz Matalobos at IE Business School, Juan Pons, Motorola Spain. and Stephan Pahls, University Hospital, Basel. Original version, 15 June 2010. (R.L. 19 January 2012). The authors acknowledge the generous support of Aravind while conducting the field research. Published by IE Publishing Department. María de Molina 13, 28006 – Madrid, Spain. ©2010 IE. Total or partial publication of this document without the express, written consent IE is prohibited. INTRODUCTION Improving efficiency in health care is an acute issue. In the developed world this is due to increases in costs and quality issues (Aptel and Pourjalali, 2001; Spear, 2005); Western Europe currently spends 9% of its GDP on health care, and, if the trend continues, will spend over 20% by the year 2050 (Drouin et al., 2008.) In the developing world on the other hand demand exceed capacity; it was estimated that in 1997 over 12 million people were blind in India from cataracts, while a further 3.8 million new cases are developed each year, and current capacity for surgery is far below this level (Thulasiraj et al., 1997.) Better health care operations are clearly required to deal with issues of ageing population, increased costs and unmet demand. One case that provides clues to such means is Aravind, the largest eye care provider in the world, with over 2.5 million operations performed and 20 million patients treated in...

Gemstone Reflection

...When deciding to attend the University of Maryland, the Gemstone Honors Program was an enticing attribute. It would allow me to be a part of a smaller group as soon as I started at UMD. I decided against the larger University Honors Program because I could get lost in such a large, unspecified program. With Gemstone, I immediately was involved on campus with a well-known, prestigious group. In addition to enjoying the specificity and closeness of Gemstone, I also was very excited for the research aspect.

Technology Decision Making Paper

...Technology and Decision-Making Paper Allie Timbo Health Care Informatics HCS482 November 8, 2010 Richard Ong, MBA, FACHE Technology and Decision-Making Paper More than ever before, information technology is helping clinicians and health care systems improve the collection and management of data along with the ability to aid in decision–making for clinical and business issues. Information technology has led to significant improvements in quality of care, patient safety, and communication between clinicians. The key to information technology and decision-making is to develop relationships between information technology and the users to make effective decisions. Systems that support decision-making assist the user’s ability to make short and long-term decisions by providing information to make decisions concerning particular situations. Health care informatics “incorporates theories from information, science, computer science, and cognitive sciences” (Englebardt & Nelson, 2002, p. 5). Health care informatics specialists use theories, and the Data, Information, and Knowledge (DIK) Model to guide their practice, which in turn supports clinical practice and optimizes health care delivery. Systems and Informatics Theories Theories are useful in several ways. Theories form a reference point for information technology and users. Without theories users would spend time condensing information and data from empirical sources. According to John Holmes, chairperson of the American...

African American Scientist

...of exploring new cultures. Her mother piqued the young girl's interest in science by buying her a chemistry set. As a result, Bath worked hard on her intellectual pursuits and, at the age of 16, became one of only a few students to attend a cancer research workshop sponsored by the National Science Foundation. The program head, Dr. Robert Bernard, was so impressed with Bath's discoveries during the project that he incorporated her findings in a scientific paper he presented at a conference. The publicity surrounding her discoveries earned Bath the Mademoiselle magazine's Merit Award in 1960. After graduating from high school in only two years, Bath headed to Hunter College, where she earned a bachelor's degree in 1964. She then attended Howard University to pursue a medical degree. Bath graduated with honors from Howard in 1968, and accepted an internship at Harlem Hospital shortly afterward. The following year, she also began pursuing a fellowship in ophthalmology at Columbia University. Through her studies there, she discovered that African Americans were twice more likely to suffer from blindness than other patients to which she attended, and eight times more likely to develop glaucoma. Her research led to her development of a community ophthalmology system, which increased the amount of eye care given to those who were unable to afford treatment. In 1973, Patricia Bath became...

Research Applications Paper

...Business Research Applications Paper RES/320 Research is used in every profession. Whether it is used to take a consensus for interest in juice bar flavors, or to isolate the blood type required for a successful transfusion, it is how all necessary questions get the appropriate and most accurate answers. I work for an organization that provides medical care. Specifically, I work for an ophthalmic clinic and surgical center. Our physician specializes in ocular diseases and refractive correction. Ocular, meaning eyes, is our specialty. Research has been used in this business by almost every person, at all times. From the initial purchase of facilities, to the expansion of facilities, to the care, diagnosis, and treatment of the patients, research is a vital part of our sustainability. Research is a key factor aiding in the physicians ability to diagnose and treat patients. However, additional consideration may need to be taken into account when providing care. When my family first had the idea to start this business, we had no idea where to begin. It was important to do some market research of our own. My father, who would be the physician, had been practicing medicine for years. However, he was no more than a shareholder in the practices he was employed by. He had never started his own practice. However, he knew from experience what type of facility he wanted to work out of and what type of diagnostic equipment would be required. My mother, who would be the CEO, was using...

Animal Testing

...used for Research During the past ten years, a major controversy over the use of animals in biomedical and behavioral research has arisen. The debate about using animals for medical testing has been ongoing for years. The struggle is usually between animal rights activists and scientist. I believe that animal testing is imperative to the progression of medical cures, procedures and drugs. Scientists have been solving medical problems, developing new techniques and treatments, and curing diseases by using animals in biomedical research. Animal rights advocates believe that animals should not be exploited by humans, and that animals have the same rights as humans. Anti-vivisectionists oppose the use of animals in medical research. They believe that medical researchers are cruel and inhumane. Animal Welfare does not oppose all use of animals in research. They oppose inhumane and unnecessary use of animals and fight to eliminate pain and suffering of animals. On the Contrary, scientists argue that animal research is necessary because it helps them develop medications, vaccines, or new procedures to treat or prevent diseases for both humans and animals. Most research projects either do not involve pain or the pain is alleviated with analgesic or anesthetic drugs. They understand that pain causes stress for the animals, and this stress can seriously affect the results of the study. With all these controversies about this issue, why are animals necessary in research? Because...

The Role of Technology in Rising Health Care Costs. What Should or Shouldn’t Be Done.

...The Role of Technology in Rising Health Care Costs. What should or shouldn’t be done. Neha Para, MPH Student 5453-001 US Health Care System University of Oklahoma Health Sciences Center December 8, 2010 Abstract Health care costs are a longstanding concern to policymakers. For years, health care spending has been rising faster than the rate of economic growth, raising the question of what factors are responsible for rising health care costs. This paper explores published articles that report results from research conducted on technological innovations in health care and its relation to rising health care costs. The cost increases have a significant effect on households, businesses, and government programs. Health care experts indicates the development and diffusion of medical technology as primary factors in explaining the persistent difference between health spending and overall economic growth, with some arguing that new medical technology may account for about one-half or more of real long-term spending growth. Rising health care expenditures lead to the question of whether we are getting value for the money we spend. On an average, increases in medical spending as a result of advances in medical care have provided reasonable value. An alternative viewpoint holds that although new technologies represent medical advances, they are prone to overuse and thereby excess cost. Most of the suggestions to slow the growth in new medical technology in the U.S. focus on...

Diabetes

...Approximately 17 million Americans have diabetes.(Lamb) As many as one-half are unaware they have it. This chronic disease causes serious health complications including renal failure, heart disease, stroke, and blindness. It is a condition in which the pancreas no longer produces enough insulin or cells stop responding to the insulin that is produced. Then glucose in the blood is not able to be absorbed into the cells of the body.(Kishore) The cells in the human body need energy in order to function. Glucose is the body's primary energy source. It is a simple sugar resulting from the digestion of foods containing carbohydrates. It circulates in the blood from the foods that are digested as a ready energy source for any cells that need it. Insulin is a hormone or chemical produced by cells in the pancreas, it is located behind the stomach. It bonds to a receptor site on the outside of cell and goes into the cell through which glucose can enter. Glucose can be saved for later use by converting to concentrated energy sources like glycogen or fatty acids. When there is not enough insulin produced , glucose stays in the blood rather entering the cells. The body will attempt to dilute the high level of glucose in the blood, which called hyperglycemia. Hyperglycemia acts by drawing water out of the cells and into the bloodstream, to dilute the sugar and excrete it in the urine. People with undiagnosed diabetes to be constantly thirsty, drink large quantities of water, and urinate...

Retinoblastoma

...Dylan Spille March 2, 2013 6th hour Pre-AP Biology “Retinoblastoma Research Paper” “Retinoblastoma” Retinoblastoma is a cancer that develops in the retina, but can be cured with the right information and technology to help. Retinoblastoma is a childhood cancer that forms in the retina. It is a progressive genetic disorder. The retina is the light sensitive part of the eye. The retina covers approximately 65% of the interior of the eye. In immature retinal cells, the cancer will develop in children from the time the eyes develop in the womb to 5 years of age. The tumor starts in the retina, the light sensitive layer of the eye, which allows the eye to actually see. “ It can occur in either one eye (unilateral) or two eyes (bilateral)”(Hulett, WashBurn, and Orenic). If the cancer is caught early, it is curable, but if caught late, it is deadly. That is why in developing countries, 87% of children worldwide with this genetic disorder will die. For developed countries, 97 % survive but will have moderate to severe visual impairment. Before enucleation was known to help retinoblastoma, it was incurable. It was considered incurable and death always occurred because inheritance patterns had not been established, leading back to more deaths. But in all actuality, the survival rate will drop with every decade of life when the patients have the genomic mutation. The genomic mutation is a gene mutation within every cell of the individual’s body. Those patients...

...countries to obtain medical, dental or cosmetic care. Medical tourism is a new term but thousands of years old act. People have been traveling across the continents in search of cures for any imaginable illnesses and making therapeutic trips for health wellness. In ancient Greece, pilgrims and patients came from all over the Mediterranean to the sanctuary of the healing god, Asklepios at Epidaurus, and from the 18th century wealthy Europeans have been traveling to spas from Germany to the Nile. In recent years, medical tourism is becoming more popular with patients seeking treatment for health and well-being purposes abroad. Medical Tourism is also known as Medical Travel, Health Tourism, Surgical Tourism, Health Travel, Treatment Abroad, Surgeries Abroad, and Medical Outsourcing. Medical Tourism Concerns Though many are eager to be the right pieces in the puzzle, many are still struggling to get the right fit. There are a number of concerns and risk factors for patients getting treatment much less seeking them abroad. Some concerns for patients include a consistent quality of care, lack of extensive dialog between the patient and the doctor, lack of post-op follow up, cultural differences and difficulty in obtaining sufficient insurance coverage. In order to mitigate the risk, it’s essential that the patient works with well reputed facilitators.
