The Importance Of Cataract Surgery

820 Words4 Pages

Cataracts are most commonly due to aging but may also occur due to trauma or radiation exposure, be present from birth, or occur following eye surgery for other problems.[1][2] Risk factors include diabetes, smoking tobacco, prolonged exposure to sunlight, and alcohol. Either clumps of protein or yellow-brown pigment may be deposited in the lens reducing the transmission of light to the retina at the back of the eye. Diagnosis is by an eye examination.[3]. In any society, a patient’s visual function (VF), which is a measurement of the important vision‑dependent tasks or she can do, is a more important measure of the need for cataract surgery .[2] The impact on VF is related to patient‑perceived outcomes and has become a significant factor in …show more content…

This has been proven in this study that shows that despite growing age and low vision, the study population was gainfully employed and expected to be able to do so after cataract surgery. The study also shows that though the quality of life of the patients was compromised yet, reasonable VF permitted them to continue working because of the nature of their job that does not require fine acuity of vision. The results of our study show that even though majority (62%) of the study population was more than60 years old, most of them (88%) were gainfully employed. Other studies conducted in developing countries have reported similar observations.[11]. An African study had reported a similar age at a presentation at 66.5 years[12] where as Conner‑Spady et al. had reported the mean age of patients in Canada to be 73.4 years.[13]The fact that the study population had severe visual impairment and yet they were going out to work brings out the fact that despite low vision, they were not only independent in their daily activities but also contributed economically toward their households. It also indicates that the profession in which the study population was engaged does not require fine acuity of vision. Farm laborers pull out weeds from among the crop that is done with bare handsand does not require the use of sharp instruments. The attitude of the study population toward their visual incapacity reinforces the observations of a study conducted in Egypt that had concluded that stigmatizing attitudes that the blind are completely dependent and unable to fulfill their social roles encourage those with decreased vision to deny the extent of their visual

Shortly after his surgery and the loss of sight be started to fall into depression and I was able to see he really needed some help.

The history of blindness came from a time where it was difficult to even keep someone around that was blind. People were giving away their children, abandon them, leaving them to die (Omvig 2017). As shocking as it is, of course everyone is scared of the unknown, this was not very common and seeing someone who was blind was a whole new thing. Once it became a very common

For example, “The strong wore weights to make them weaker; the intelligent wore earpieces that kept them from taking unfair advantage of their brains. Even the beautiful sometimes wore masks in situations where their beauty might simply be … too distracting” (Tupper 2). That is where handicaps differ from modern society. In American modern society people use handicaps to help them, like glasses and crutches. For example, “The purpose of eyeglasses and contact lenses is to correct or improve the vision of people” (Eyeglasses and Contact Lenses).

In "All the Light We Cannot See, " by Anthony Doerr, the author is giving insight to the lives of the blind. Usually people have pity for those who cannot see, but they don’t always acknowledge that these people are able to live normal lives. For instance, in lines 1 through 9 when it says “Sixteen paces… hedges and sidewalks” Doerr shows how the main character, Marie- Laure is able to go about her day. Here it is shown that she is able to map out how to move around, who people are and where she is, based on smell. Also, many believe that those who are blind, just live in darkness, but the author is trying to show that is not the case, when he exclaims, “Color… people don’t expect” (line 18).

Isabelle Carroll  Hours 4 & 5  November 15th, 2016  Argument Essay  Charlie Gordon's doctors did not act ethically as they performed the surgery on him to increase his intelligence. Ethics are what people consider to be morally right and wrong. The scientists decided that it would've been morally right to conduct their own experiment on Charlie Gordon. However, the scientists may have acted ethically by conducting the experiment to see if they can improve the intelligence of the entire society. It is unfortunate that the disadvantages outnumber the number of advantages because the ratio shows that the scientists should not perform the surgery, as there are more risks than benefits.

When blindness is referenced the first thought that comes up is the actual disability. Blindness doesn’t always come in the form of a physical impairment but can often times have a figurative meaning. Sophocles, J.C. Oates and Nathaniel Hawthorne demonstrate this act of figuratively referencing blindness in “Oedipus the King,” Where Are You Going, Where Have You Been” and “Young Goodman Brown.” Although some may say that the truth will set you free, for the characters in these stories it decides their fates. The story of “Oedipus the King,” tells a tale of the great ruler of Thebes who has become the culprit of a plaque that is among the city.

When trying to understand how blindness affects those who are its victims, he was searching for a standard experience that he believed all blind people go through. He states, “Was there any such thing, I wondered, as a typical blind experience” (Sacks, 336)? Oliver was under the impression that there was a conventional process where

The same can be said when comparing the Canadian legally blind population to the general population living with disabilities in Canada. In 2006 the general unemployment rate in Canada was 6.8%, which did not account for those who are living with disabilities. The unemployment rate for Canada’s population living with disabilities was 10.4%, and the unemployment rate for the legally blind population was substantially higher at 26.4%. This shows that legally blind people are 4x as likely to be unemployed than those without a disability, and 2.5x than those that do have a different disability (Benoit et. al, 2013).

For anybody, being employed can have a crucial impact on their lives. It also has great importance on our social and material well being. Income, self-esteem, identity and sense of independence are just a number of benefits that people can gain from being an active and useful member of the workforce. Yet from a historical perspective, many disabled people have been denied such benefits because of their exclusion from mainstream social and societal activities such as worthwhile employment in particular. Interestingly, disable workers have in the past found themselves welcomed and encouraged into employment during time of shortage of able bodied workers during times of war (Barnes, Mercer & Shakespeare 1999, p.22).

You don't have to physically be able to see to understand complex ideas or be able to gain knowledge. “If there was a subconscious thought of it, it was in the nature of gratitude of God for having given the blind seeing minds.” ( View From the Empire State Building 4) Keller explains how the blind are not able to see physically, but can see through their minds which may give them a better insight on many topics. Blind people are not able to see physically, but are given a better insight to be able to see mentally and can gain and understand deeper than those who are able to see with their

Introduction Vision is one of our most valuable sensory modalities, it is the way that we as individuals identify our surroundings and ourselves. African American children at a young age are more susceptible to having eye problems mainly because of the fact that they are still children and still exploring their surroundings. It is estimated that around 500,000 children become blind each year but that number is expected to grow. In developing countries that statistic is even worse as around 60 percent of individuals die within a year of becoming blinded (NIH, et al, 2015). This brings about the question as to what are the true causes of these blindness’s

This may be due to mechanical trauma (blunt or penetrating), thermal injuries,chemical agents or radiation.1 Ocular trauma is an important cause of visual impairment and a leading cause of preventablemonocular blindness.2 Worldwide there are approximately 1.6 million people blind from eyeinjuries, an additional 2.3 million people with bilateral low vision from this cause, and almost19 million with unilateral blindness or low vision.3The global pattern of eye injuries and theirconsequences suggest that 55 million eye injuries restricting activities more than one day,occur each year and 750,000 cases will require hospitalization each year.3,4Data from the National Centre for Health Statistics' Health Interview Survey, conducted in1977, estimated that nearly 2.4 million eye injuries occur in the United States yearly.5 Thisreport also estimated that nearly one million Americans have permanent significant visualimpairment due to injury, with more than 75% of these individuals being monocularly blind. Eye injury is a leading cause of monocular blindness in the United States, and is second onlyto cataract as the most common cause of visual impairment.2,5In developing countries, eye injuries are not only more common but also more severe in theireffect and this may be attributed to socioeconomic background, inadequate safety measures,lack of
