With so many advancements in technology these days, almost every aspect in the society has received their fair share in the modernization of processes and standards. Among them is the field of optometry. As an optometrist for many years, I have seen these technologies evolved, seen how new techniques were discovered and how new tools have been put in place. All of these positive impacts of technology are certainly working towards the best of the people who are, in their own way, need of assistance.
As a doctor, I am personally watching out over these developments. Of course, I would not want to be behind when it comes to providing what I think would work best with my patients. Here are three of the latest developments in the field of optometry that I have seen so far:
Innovation in Contact Lenses
Contact lenses, by far, are considered as among the fastest growing topics in the field of optometry. As a matter of fact, during the last decade, there has been a considerable amount of developments in that particular aspect. Among those are the dominance and the existence of soft lens materials which are far more comfortable compared to the traditionally designed ones. Since the optical designs have significantly improved, optimization on distance vision is enhanced with the use of enhance range of clear focus, aspherics, mutifocals, as well as toric designs which is used for correcting astigmatism. At the same time, the technology of using silicone hydrogel has also increased oxygen permeability on the eye, improving ocular and corneal surface as a result. Plus, even fashion lenses are created to feed people’s desire to exhibit fashion through their eyes.
Eye Tests Can Detect Early Stages of Alzheimer’s
Just recently, it has been discovered that eye tests can now be done in order to detect early stages of Alzheimer’s. This is done by detecting proteins present in the retina and lens that are commonly associated with the disease. The discoveries support a series of tests conducted which would eventually be used in detecting the earliest signs of Alzheimer’s before it can start impairing the cognitive functionalities of the brain. The research conducted primarily focused on the ultimate detection of a protein called beta-amyloid, which may incorrectly fold to Alzheimer’s. This is one of the root causes of the disease.
Human Corneas Can Be Regrown
A team of scientists composed of Harvard affiliated centers have attempted growing corneal tissue from the human eye to a mice through the use of human adult stem cells. This study was conducted in order to provide hope to individuals whose vision has been impaired or lost due to different reasons. This works supporting the concept that the cells making up our cornea are damaged constantly due to exposure to unlikely components of the outside world, and even through blinking. In order to repair this damage, the eyes have the capability to maintain a minimum number of ‘limbar stem cells’, at the cornea edge. This breakthrough is good news in the world of optometry.
