From frame glasses to contact lenses to laser correction, humans have struggled with visual impairment for hundreds of years. Nowadays, a new technology may soon eliminate this problem - not only to correct vision, but also to enhance human visual ability.
According to reports, a bionic lens developed by Ocumentics, a medical technology company in Canada, has entered the final clinical trial stage. Dr. Garth Webb, the company's founder and bionic lens developer, said that with this lens, it takes only ten seconds, and vision can be quickly corrected and restored, even three times better than 1.0.
According to reports, this bionic lens looks like a piece of cereal, the material is a highly biocompatible inert polymer that does not cause human rejection.
In a recent experiment, subjects with bionic lenses were able to see the smallest line of letters on the eye chart 20 feet behind a person with normal vision. Dr. Garth Webb said that in order to develop this technology, Ocumentics spent $3 million (about 15.168 million yuan) over the past eight years.
The surgical procedure is similar to cataract intraocular lens implantation. The doctor first removes the crystals in the patient's eyeball, and then implants the bionic lens. After rinsing with saline, it takes only ten seconds of bionic lens to expand in the eyeball and correct vision immediately. The entire procedure lasts about eight minutes, and the patient does not feel pain and irritation, nor does it require hospital care.
According to Dr. Garth Webb, this technique is very safe, but it is only suitable for adults over the age of 25, because the eye structure of people below this age is not yet mature. In addition, patients with corneal opacity, cataract surgery, severe macular degeneration, severe hereditary retinopathy, optic nerve injury and other diseases are not suitable for this therapy.
According to the company's website, the cost of surgery for each eyeball is about $3,200 (about 162,000 yuan).
British Columbia Ocumentics headquartered in Canada, is a ophthalmology biomedical technology companies. At present, Ocumentics bionic lenses have completed animal experiments and are entering the human clinical trial stage, and are reviewed by the drug regulatory authorities in North America and Europe within two to three years.
The company also established a foundation called "Celebration of Sight" to help visually impaired patients in developing countries raise funds for surgery and improve their vision.
