Eyesight problems have affected human beings for the better part of our history. With this problem being a constant phenomenon, we have historically delved into trying to rectify the problems of nearsightedness and farsightedness. With this in mind, the history of rectifying eyesight defects is long running. Herein we will look at some of the most notable milestones in as far as correcting eyesight problems is concerned.
Around the 13th century, glasses correcting vision defects first appeared in Italy. However, the science behind their use had not been perfected, and the users did not understand how to best use glasses to rectify the glasses.
In 1508, the renowned scholar and inventor, Leonardo da Vinci illustrated the concept of contact lenses. However, development in the field took a few more centuries before people could have practical solutions. It was not until the 1800s that contacts were developed for use. However, they were anything but comfortable.
With the rapid development experienced it in the 20th century, corrective eye care industry developed tremendously, incorporating new and groundbreaking procedures. 1978 saw a method to fix myopia introduced in the U.S. The procedure, known as Radial Keratotomy (RK) saw surgeons cut small radial slits in the cornea to influence how light interacted with the retina. However, the procedure is highly discouraged due to a myriad of complications involved with the procedure.
The 1990s saw the introduction of the Mini Asymmetric Radial Keratotomy, better known as MARK as a viable alternative to corneal transplantation and grafting. This procedure focused on cure keratoconus. Keratoconus is a condition where the corner of eyes are shaped. In this regard, surgeons used diamond knives to make small cuts. It was also thought to cure astigmatism.
Thereafter, there was the development of the Automated Lamellar Keratoplasty (Or AKL). During this procedure, the microkeratome removed small eye tissues with the aim of improving how light reached the retina.
The next developement in the field of eyesight care was the Photorefractive Keratectomy, better known as the PRK procedure. The procedure used excimer lasers to correct vision. This procedure used UV light to change the cornea. It was a precursor to the now popular Laser Assisted Sub-Epithelium Keratomileusis, better known as LASEK procedure. The FDA approved LASIK in 1999. These two methods are characterized by fast recovery times and relatively reduce risks. Click this link for more information about LASIK or to find LASIK surgery in our city.
This has been a very brief analysis of the chronological development in eyesight care that has been seen to improve the eyesight of human beings all around the world.
