Like obesity and diabetes, the percentage of people getting myopia is rising every single year that we can even say that it has become an epidemic. According to National Eye Institude, more than 30 percent of U.S. population is affected by myopia. Usually it occurs in school-aged kids, but adults can be affected too due to eye stress and optic illness. For people who are diagnosed with myopia, seeing things clearly without glasses or contact lenses is becoming a reality in the near future.
After eight years of extensive research with $3 million in funding, an optometrist from British Columbia, Dr. Garth Webb of Ocumetics Technology Corp has developed a highly advanced intraocular lens -- “Ocumetics Bionic Lens”, in which Dr. Webb claims that it can give people age 25 and above 20/20 visions (Celebration).
The implantation of bionic lens takes as little as eight minutes. During this “painless procedure”, the bionic lenses, made of

Once the device is approved by national authorities, bionic lenses could change the future of corrective vision, and glasses and contact lenses will become obsolete. Nowadays, people spend hundreds of dollars on glasses and contact lenses every year. But with this technology, people will be able to have a life-long good vision with bionic lens implantation, which is a one-time operation that costs only $3,200 per eye.
Neither the material or the technology involved in the implantation is completely new, however, it is the concept that is revolutionary. This type of lens is not about simply correcting eye conditions, but restoring the eye to its original and healthy state. Because of its unique materials, bionic lenses will not cause biophysical changes within the eyes. Thus, this will be an ideal alternative to traditional eye surgery as it prevents the decay from reoccurring in the
Many times, people are left with an impaired brain for the rest of their lives and that damage can extend from being unable to control a limb to damaged eyesight to major memory loss. The purpose of implants is to aid the damaged portion of the brain to eradicate the symptoms that are associated with these serious brain disorders. Implants are inserted in the section of the brain that is impaired, whether it is the frontal lobe to help motor skills or in the occipital lobe to aid
Optometrists have accepted vision therapy, which is a medical treatment for optical muscle disabilities, as a feasible treatment used for eye related problems; claiming the treatment can strengthen vision and give the patient the opportunity to understand visuals quicker and clearer (Press). Vision therapy originated in the 1950s and over the past 25 years, has gained popularity, mainly because of new technological innovations in the field of treatment. Generally, vision therapy is prescribed as a measure mainly for people between the ages of 3 and 18. With the results from a comprehensive series of eye tests, the optometrist can work with the patient using special instruments—prisms, filters, occluders, and eye lenses—and strengthen the eye muscles, thus improving sight. According to optometrists in favor of vision therapy, these methods of treatment using these instruments function as safer routes to repair eye disabilities. Although vision therapy can yield favorable results, the practice as a treatment for innate eye disabilities has been in hot debate lately; as it can exceed $8000 and insurance companies do not cover the treatment. For decades, insurance companies have refused to accept vision therapy as a legitimate method for repairing eyesight (Boink). Concomitant with lack of insurance, the cost for a full treatment can exceed $8000, and doctors cannot guarantee a successful outcome. Recently, parents of children with eye related disabilities, such as amblyopia (lazy eye) and strabismus (cross-eye), and doctors have attempted to cooperate with public schools to allow families access to school-funded doctors to practice vision therapy. With a tight budget, most schools cannot afford to supply vision therapy, and a...
As I was out my Mom and Dad stayed and waited the whole time, a total of 3 hours. Normal Strabismus surgeries take 1-2 hours, mine took longer because of how bad the turn was in my eyes. The turn of both eyes was the same, a 66 degree turn, normal eyes have the degree between 3-7, you can't even noticed them. The turn was also affecting both of my eyes so I could switch which one I wanted my focus out of. My vision was never effected, I have always had 20/20 vision that's another reason I was upset I had been stuck with glasses and contacts my whole
Over 10,000,000 people around the world suffer from some sort of blindness or handicap due to photoreceptor damage. These effects can be caused by a number of afflictions, including retinitis pigmentosa, macular degeneration, and tumors. These illnesses vary in severity from being a mere hindrance to completely blinding the individual. Until recently, those affected were left without hope of a cure or even a treatment that would somewhat improve their vision. But over the last few years, several groups of scientists have been working on a partial cure in the form of neuroprostheses, artificial devices which are inserted in the eye behind or on top of the damaged retinal area. These photoreceptive chips, in theory, should provide information too the healthy neurons residing in the retina, substituting for the damaged photoreceptors.
...e cells from the synthetic retina had moved and integrated as it looked like normal mature rod cell after six weeks. Professor Ali says that it will take few years to implement this research within a human trial, but the team has already started working with human embryonic stem cells. I really wish this experiment works with human because blindness is the hardest thing to cure and it is really hard to find the eye donor. Doing this stem cell research, it reminded me of my grandmother when she had a stroke. She was really lucky because my grandfather found her very quickly, when she fainted from the stroke. The doctor said that she still has a chance of getting stroke again so she always has to be careful. If the stem cell research develops, my grandmother will be able to cure the stroke clearly and we won’t have to worry about her anymore going to hospital again.
Fortunately, cataract formation on the optical lenses proves to be a malady that is simple to fix. Future scholarship on such a topic could serve to address the remaining high statistic of blindness due to cataracts. Perhaps formation of cataracts is under diagnosed due to limited health care availability for some individuals.
2. There are patients that have ocular hypertension which is high pressure in the eyes. When this ocular hypertension is left untreated, it can lead to glaucoma. Usually when people have glaucoma they have to treat it with eye drop frequently. ForSight Vision5 is a product for people that they can be put into their eyes as a replacement for eye drops that is a therapy for glaucoma and other eye diseases. When he passed around the product I was very intrigued how that ring can fit in your eye. Currently this vision 5 is still in clinical trials but have a lot of investors interested in their product. This product releases the drug slowly in a period of months.
These symptoms interfere with your ability to drive safely at night, your work productivity in a job involving digital display screens, and your study and test taking abilities as a student. Frequent rest is recommended for avoiding eyestrain. However, if your high index eyeglasses do not have an anti-reflective coating, you are not addressing a root cause of the problem, which of course, is glare.
Bionics, or sometimes called bionical creativity engineering, is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology (“Bionics” n.p.). It is a mechanical prosthetic that is hooked onto a set of nerves, depending where it is placed, that retrieve signals from the brain to the limb. Bionic limbs give amputees a new feeling of living a more natural and normal life.
Understanding how our eyes work can be a really interesting thing. Many people don’t realize vision actually begins when light rays are reflected off an object that then enters the eye through the cornea. The cornea is a transparent bulge, in the front of our eyes that allows us to begin refraction. The cornea is one of the most important things in our eyes that allow us to see the things we do. After the reflected light rays enter the cornea, they then p...
The surgeon can use a mechanical microkeratome, a special blade, or a laser keratome, a cutting laser, to cut a flap from on the cornea. In the case of a doctor using a mechanical microkeratome, a ring will be placed on your eye to create ...
This theory is the most relevant to Aravind’s Eye Hospital as Dr. G. Venkataswamy has helped motivate his doctors to work and perform many more cataract surgeries than most doctors can deal with. His doctors perform in the region of 25-40 surgeries a day. The Aravind Eye Hospital has also inspired the world with its actions, no believed that it would be possible to deal with the ongoing sight problem especially letting 2/3 of patients go free. He also inspired people to show how he can do this individually by manufacturing and providing his very own cataract lenses. Aravind built its own solution for the extensive prices of lenses, they created a manufacturing plant in the basement of one of his hospitals. They realised soon enough they could use affordable and obtainable pieces of technology to help produce the lenses at the price of $4 per lens. (Brown, T. Design Thinking) Dr Venkataswamy had defied all odds and his family still continues to use The Transformational Theory in his work to this
I believe that these implants are a fantastic and very fascinating idea! To think that someone who has never heard a person laugh or see someone smile being given that opportunity is a wonderful thought. These implants, if we can focus and direct how they influence the brain, could allow us to solve major diseases by studying the impact of the disease on the brain, and programming the implants to stimulate or lesion the problem-areas. This article was definitely one of the more intriguing pieces I’ve read recently, and I would absolutely recommend this to a friend. I hope that, in the future, these implants can positively affect the lives of millions of others without the pecuniary anxieties of the
By convention, the field of healthcare research was entirely occupied by physicians and doctors. They were the ones who came up with new methods to treat diseases and get better results from diagnostic tests. Technology, on the other hand, was always looked at as a way to solve problems that we faced that didn’t pertain to the medical sector. It was employed to enhance the quality of life and make day to day work easier. But as technology progressed, so did the areas of application. The structural balancing techniques which were previously used to hold a building steady were now being used to develop near-perfect artificial joints and prosthetic limbs. Transparent polymers, developed to enhance robotic vision, were being suggested as a candidate for an artificial lens for the human eye. Before anyone could even understand what was happening, engineering had taken up the mantle to further medical technology to dizzying new heights.
Have you ever wondered why the sky is blue. Often times I find myself looking up on a clear day, pondering over that question? Why isn’t it green, or red or pink for even that matter. Every day, the human eye blinks more than 23,00 times. The human eye is a complicated organ that performs one of the most important tasks for our body. There are many questions about the eye however. What function do they perform? What happens if we don’t take care of them? How exactly do they work together to help us form images? Exactly how far can they human eye see?
