LASIK Surgery Then And Now

LASIK Surgery: Where Did It Start And Where Is It Today?

Innovation in vision correction started a long time ago, much farther back than you would likely guess. The 1st eye glasses originated in Italy throughout the 13th century, as the first disposable lenses, that were crafted from hand-blown glass, appeared in Switzerland in 1888.

But neither of the inventions offered a permanent strategy to not so perfect vision. That didn’t come before the excimer laser was invented within the 1970s. When Stephen L. Trokel, a Columbia University researcher, heard of this laser technology, he borrowed it to perform the 1st laser vision correction using animal cadavers, then human cadavers, and ultimately working his way up to performing the surgery on living monkey and rabbit corneas.

Improvements Over Time

Scientists designed a wavefront analysis in 1999 that can map a patient’s prescription. This map, referred to as a corneal map, can be as unique to each patient as a fingerprint.

Your data from the wavefront analysis could possibly be programmed in the excimer laser, allowing the laser to complete an even more precise job of reshaping the patient’s cornea, offering a totally customized procedure with much better results.

The First Laser Vision Correction Procedure

Marguerite McDonald, a colleage of Trokel’s, performed the 1st live human Photorefractive Keratectomy (also known as PRK) in 1988. This became done on the 60-year-old woman whose eye was scheduled being removed as a result of growing black spot on the eye due to malignant melanoma. The lady offered scientists the ability to experiment on her eye before it absolutely was removed, and so the PRK procedure was performed. Learn more about this at

It was later that same year that Canada approved the excimer laser to be used in PRK, and america approved it in 1995.

More Improvements

In Europe, there were 2 doctors, Ioannis Pillakaris and Lucio Burrato, who developed the 2 kinds of surgery known then as “flap and zap.” They used a blade to reduce a thin flap to the cornea, and “zap” the actual tissue by using a laser, then make use of the flap as being a natural bandage.

This flap resulted in much less discomfort than merely working on the surface of the cornea, and allowed for faster time to recover. This procedure became generally known as LASIK, which had been approved in the states in 1999.

The use of Wavefront analysis data was approved by the Federal Drug Administration in 2002. This also coincided with LASIK becoming the most typical elective procedure on earth.

That same year, 100 % bladeless laser eye surgery was invented. As a different approach to using a blade to make the corneal flap, a femtosecond laser is commonly used, which could create an incision of your precise depth and diameter the surgeon desires.

LASIK is proven safe and efficient, whether done bladed or bladeless, and gives patients with important benefits, including almost no pain, almost same day vision improvement, quick recovery without any bandages or stitches, and the potential of not any longer needing corrective eyewear.

Like most surgical procedures, there are several risks along with possible effects you do not want, Lasik offers a permanent vision correction solution for lots of people with vision problems who find wearing glasses or contacts to be a nuisance.

LASIK surgery and improving vision has made a lot of progress to this point, from monocles and spectacles to hi-tech LASIK surgery. One could only wonder what future vision correction might have in store.
