3 Ways Technology Is Set To Benefit Eye Treatment
From artificial intelligence to augmented reality, the impact of technology is reverberating across every facet of life and is now infusing hope to those who have visual impairments. With more than 36 million people having complete vision loss, meaning that they can’t even see the sources of light, technology is offering a glimmer of hope in different ways.
Developments in Optical Imaging Technology
With early diagnosis, most eye patients can receive effective treatment for their eyes. However, because of late diagnosis or insufficient imaging equipment, patients often lose their sight.
Imaging technology helps doctors to assess any changes to your retina whenever you go for eye check-ups. Notably, Digital Retinal Imaging aids doctors to evaluate the health of your eye. The procedure documents the condition of your eye for comparison with future results and notes any changes that have occurred.
Additionally, the Optical Coherence Tomography scan helps to analyze layers of the optic nerve and Retina for any signs of eye disease. Working like a CT scan, the technology uses light without radiation and is vital in the early diagnosis of macular degeneration, glaucoma, and other retinal diseases.
Scientists are increasingly developing various imaging technologies that are providing preoperative biometrics required before surgery. Moreover, the use of imaging technology at the preoperative stage and during surgery has dramatically improved eye treatment. Collectively, the use of imaging technology before and during surgery has facilitated faster visual recovery and positive outcomes such as spectacle independence
Use of Multifocal Intraocular Lenses
Cataracts are the leading cause of blindness and a significant cause of low vision in both developing and developed countries. The remedy to the situation lies in getting cataract eye surgery.
Cataract eye surgery is a surgical procedure to remove the eye lens when it gets cloudy. Generally, the eye lens should be clear, but with a cataract, it becomes misty and impairs visual ability. A surgical procedure is mandatory to remove the cataract. However, after the process, most patients depend on spectacles for optical clarity.
The development of multifocal intraocular lenses (IOLs) has enabled those who have passed through cataract surgery to remain spectacle-independent. Rather than merely fixing the foggy vision, surgeons implant a refractive lens in the patient’s eyes to improve his sight.
Additionally, the development of trifocal lenses has enabled patients to read at intermediate distances, which varies from bifocal lenses that only allow you to see things close to you.
Bionic Eye implants
Bionic eyes promise to offer an artificial vision to the visually impaired people who could initially see. The device has micro-electrodes which have to be surgically inserted into the brain or in one eye, along the optic nerve.
For those who have lost their eyesight, inserting microelectrodes can help them to see through the electrical stimulation of the functional parts of their visual system. As a result, the patients are now able to perceive minute spots of light called phosphenes.
A bionic eye works by converting images from a video camera to a high contrast image, and a part of the representation goes to the external video for further processing. The external video processor then converts the image to electrical stimulation parameters, which is transmitted to the electrodes fitted into the eye. Consequently, the recipient can perceive a blurred vision consisting of flashes of light.
