Before the 1950s, the only way that refractive vision errors were corrected was with the use of eye glasses. Then on the 1950s, the contact lenses was introduced and immediately gained popularity.
Today, with the advanced technology that mankind is enjoying there are now several modern ways that refractive visual impairment is treated. Among the laser eye surgeries are the LASIK, PRK and surgical operations that involves the insertion of artificial eye lenses in order to correct eyesight problems.
How did corrective eye surgery evolve?
In the world of eyesight correction, the methods, tools and procedures used has evolved very rapidly over the last 25 years.
In the 1980s, Radial Keratomy (RK) was a popular operation for those that were nearsighted. This operation involved cutting incisions in the eye so that the eye’s surface may flatten. The Radial Keratomy seemed to be of good effect for some patients who had lower prescriptions. But the operation brought about visual problems in the long run for patients who had higher prescription strengths.
Today, this method is not anymore practiced and had since become obsolete when medical technology such as eye laser surgery came into the picture.
In the same decade, the Photorefractive Keratectomy (PRK) became the first successful laser eye procedure. The operation was used to remove tissues that are on the surface of the eye. Its goal was to alter how the cornea curves.
Photorefractive Keratectomy is still widely used by practitioners today. However, LASIK has gained popularity and has clouded PRK. Despite the preference of people for LASIK over PRK, PRK has just recently made a comeback thanks to scholars’ studies that showed that both LASIK and PRK produce the same results.
As mentioned earlier, the LASIK procedure has now gained widespread popularity. This method of eye operation creates thinner flaps.
Another visual procedure is the Conductive Keratoplasty. This method uses low heat radio waves. These radio waves create spots around the front surface of the eye. This method will steepen the cornea, correcting people who are farsighted.
There are other non-laser surgery procedures that are also commonly used by surgeons. Today though, laser technology has eclipsed the other forms of eye surgical procedures.
