Reducing Risks in Eyesight Corrective Surgery Thanks to modern technologies, we now have the solutions to most eyesight problems. Doctors can use different treatments -- PRK, Lasik, Lasek and Intraocular lenses -- to solve all types of eyesight problems while limiting the side effects. Most eye procedures are about as safe and effective as surgery can be. However, for an industry that promises clarity, many centers have kept their patients in the dark about the risks and realities. Government are of no help either as there are no restrictions on who can buy medical instruments.
But most hospitals insist that doctors have some form of medical accreditation before performing eye surgery. Despite a good record of the surgery, thousands of people around the world get an irreversible eye operation that goes awry. The consumer-advocate website surgicaleyes.com posts a sobering series of unhappy endings -- infected corneas, triple vision, daily nausea and permanently marred eyesight. The message boards are full of people who came out of Lasik with far better vision but still in misery, handicapped by poor night vision, stinging dry eyes and worse. It's vital to research the subject if you're considering surgery. Here's a step-by-step guide to help you see things clearly. Know what you're getting into. If you believe all the ads, after eye surgery, you'll be able to read the bottom line of an eye chart through a brick wall. If only it were true. You may not wind up with a vision as good as is promised. Besides, you might be a poor candidate. Eye surgery still isn't fit for people with certain severe vision problems or an eye disease.
