The Eye And Laser Eye Surgery Essay

As vital organ of vision, the eye, allows us to learn more about the world around us more than any other organ or senses. Sight, the physical sensory experience and vision, the metaphysical concept of how our brain interprets images both work harmoniously and play a huge role in our everyday lives. However, almost a billion people are either blind or visually impaired simply due to not having a pair of glasses. Being able to lead people in the direction of good vision is what developed my interests.

There are three types of eye conditions, the nearsighted, farsighted and astigmatism. So first let us know the nearsighted or (myopia), basically means that people who are nearsighted they can’t clearly see a text or a thing that is too far from them and they need to move closer in that certain area, nearsighted people usually experiencing blur vision when they are far well they can read it but then the text itself will turn into a blur one. It can be a common cause of having a blur vision. So here is a sample picture of myopia.

The records have been reviewed. The member is an adult male with a birth date of 05/16/1973. He has a diagnosis of bilateral degenerative myopia. His treating provider, Amy Camarota, OD, recommended treatment options on 03/18/2016, one of which was scleral lenses, which the member opted and paid for on 04/01/2016.

The part of the eye responsible for refracting light in a way that allows an image to be created on your retina is the cornea. However, any imperfections in the shape of the cornea can cause blurry images to be created. LASIK surgery is a procedure that uses a laser to remove some of the corneal tissue, reshape the eye, and permanently fix these imperfections.

Laser surgery for glaucoma. Laser surgery for glaucoma slightly increases the outflow of the fluid from the eye in open-angle glaucoma or eliminates fluid blockage in angle-closure glaucoma.

Glaucoma is the disease that causes optic nerve damage and eventually loss of vision. Most people do not realise they have glaucoma until they are diagnosed and already have some decreased field of vision. Depending on what type of glaucoma the diagnosis is there are some laser treatments that can be done to help lower the pressure in the eye. Ophthalmologist will decide if a laser treatment is appropriate for the patient on its own or alongside topical therapy. Lasers are a high concentration beam of light that helps open up the trabecular meshwork in order to release the pressure in your eye. The types of lasers are Select Laser Trabeculoplasty, Laser Peripheral Irdotomy, YAG Laser Cyclophotocoagulation

An optometrist is a registered, independent, health care provider that specializes in the examination, diagnosis, treatment, management and prevention of diseases and disorders of the human visual system and its’ associated structures. The primary task of an optometrist is to perform regular eye examinations, but an optometrist might also prescribe glasses and contact lenses, rehabilitate the visually impaired, diagnose and treat ocular diseases, perform comprehensive examinations of both the internal and external structures of the eye, evaluate patients’ vision and determine appropriate treatments, treat clarity problems or eye diseases such as glaucoma and ulcers, and diagnose complications due to the aging process, accidents,

In every book, the same words appeared: “Myopia is generally corrected with the use of corrective lenses, such as glasses or contact lenses.” No other option - I could only wear glasses for the next few years, until my eyesight had “leveled out”. Oh, the horror!

First, an understanding behind the structure of the eye helps to understand the problems that can develop. Following a ray of light, the ray will first pass through the cornea, a convex and transparent lens that protects the eye. This is also where most of the refraction of

Surgical treatment has been proven to improve the visual acuity (Reacher et al., 1992), but its effectiveness on cornea opacity

Cornea-Independent is correct visual impairment without affecting the cornea, which organized into non-surgical Interventions and surgical

Refractive errors are the result of misaligned optical components within the eye causing improper focusing of light onto the retina. Although the optical components may vary by a minute amount, the resulted blurred vision will not only affect the individual but also society in terms of the health industry, education, research and socioeconomics. As a result of the impact of refractive errors, there has been an increasing emphasis for research and action plans placed by eye health organisations and the government on the development, prevention and control of refractive errors.

Another option to bifocals is monovision. You can wear monovision contacts so one eye sees far away and the other sees up close. This same theory can be applied to the LASIK procedure. When you have presbyopia, the eye surgeon will probably adjust the vision in one eye so you can read up close and adjust the other eye for clear far vision. Your brain adjusts so you can see clearly both ways. It's a good idea to try monovision contacts before you have the LASIK procedure to make sure you can tolerate it before having an irreversible surgery done on your

People who can see nearby objects clearly but cannot see or focus on distant objects are near sighted. This problem occurs because the lens converges the light rays to form an image in front of the retina, and by the time the light rays strike the retina the light have rays have begun spreading out again, which leads to blurry vision, and difficulty to see distant objects. A concave lens is used to diverge parallel rays enough for images to form further back, on the retina.

Our eyes are vital organs because they help us visualize our surroundings. But are our eyes perfect in seeing what’s right in front of us? Sadly I learned in our evolution, nature messed up at one point and gave us blind spots in our eyes. This project shows why we have these blind spots, how to discover them, and how big they are. I researched on how our eyes see things; why when one eye is closed, the other eye sometimes can’t see what’s in front of it. I also found during my research a formula that is used to estimate the size of a human eye’s blind spot. I performed an experiment using Blind Spot Test card I made to verify the existence of blind spots in my eyes. I also collected data
