Ocular Surgery 101 - The Basics of Eye Surgery

Nowadays, with our modern and advance  iGenics Review technology, methods to treat refraction now include insertion of artificial lenses through eye surgery and laser reshaping of the cornea. RK or Radial Keratotomy. Radial keratotomy was introduced in the United States during 1980s as a surgical option to correct nearsightedness or myopia. It involves cutting flatting the eye's surface by cutting spoke-like incisions. Though effective at some point, there are patients who suffered from long term problems like night vision problems, significant glare, fluctuating vision and regression. 

PRK or Photorefractive Keratectomy. Also known as the surface ablation, photorefractive keratectomy is the first successful procedure that uses laser to correct vision. It removes tissue directly from the surface of the eyes in order to change the curvature of the cornea. It was first performed outside the United States during the 1980s. It was only on 1995 that it did receive its approval from FDA.
