Overall, 98% of typical patients achieve 20/40 vision or better after one procedure allowing them to drive legally, play sports, and join the police or fire departments. Patients may receive a second enhancement procedure to further improve their results if their vision is below legal driving levels. Generally, there is a 10% chance that a patient will require an enhancement procedure. This chance is less in patients with mild myopia (approximately 5% chance) Cellulite Disappear and greater in patients with extreme myopia (approximately 20% chance).There are many resources available to explain the LASIK procedure; however, very few detail the testing necessary leading up to the procedure. These tests can be seemingly overwhelming and technical. Some of the testing could have been done at an initial consultation, though, some tests may need to be repeated.
Each test has a specific purpose to assist the surgeon in obtaining the best results possible.The first step is to determine the uncorrected visual acuity, which is vision without glasses or corrective lenses. This raises the question of “What does 20/20 mean?” In the U.S. vision is recorded on a chart with standardized letters calibrated to be read at 20 feet away. The fraction that describes vision, for instance, 20/20, 20/40, compares the smallest letters that a person with perfect vision can see at 20 feet to your vision at 20 feet. If you are only capable of seeing larger letters on the chart that can be seen by a normal person standing back 40 feet from it, then your vision is 20/40. 20/400, means at twenty feet from the chart you can only distinguish the giant E on top, which could be seen by a normal person from 400 feet away.
