Many people credit ophthalmologist and humanitarian Patricia Bath with the invention of laser eye surgery. While she was, indeed, a pioneer of laser surgery for cataracts, the therapy as we know it today has its roots in the groundbreaking work of Dr. Lendeer Jans Lans. This Dutch doctor published a theoretical paper in 1896, whereby he proposed that making incisions in the cornea could rectify abnormal curvature and cure refractive errors, such as astigmatism. To have made such accurate predictions well over 200 years ago is nothing short of astonishing.
Others who built on this theory include the Spanish ophthalmologist, Dr. Jose Barraquer and Japanese-born, Dr. Tsutomu Tsato. They both theorized and carried out research in the late 1930s. Further development occurred in the 1970s, when the work of the Russian ophthalmologist, Dr. Svyyatoslav Fyodorov further honed the technique.
The most dramatic leaps forward in the provision of laser vision correction have been seen in the last decade—indeed, even in the last few years. As we continue to push the boundaries of scientific knowledge, the techniques only promise to become even more refined in the future.
