Approximately 94% of patients have improved vision immediately after the surgery is performed. Many patients will have 20/40 vision or better after receiving Lasik surgery. There are some complications that have been reported such as:
• Seeing halos around lights at nighttime
• Worsened vision
• Infections
• Poor night vision
The FDA warns that some patients may no longer be able to drive at night due to decreased night vision. This can be a serious side effect for some people. Another long-term effect is that it is possible that correction is not permanent. Many patients have reported temporary improved vision, especially if you are already using reading glasses. Many patients have found that they still required their reading glasses after the surgery. However, the surgery is not designed to eliminate the need to wear glasses, but to reduce the need for them. Also, the need for reading glasses is caused by a natural maturity of the eyes and Lasik is not able to improve the need for these glasses.
Over six million people have received Lasik surgery. An estimated 99% of people have reported no serious complications past the normal healing period. When Lasik was new on the market, up to 5% of people who underwent the procedure had a post-Lasik problem. These number have been reduced due to:
• Improved equipment
• Increased Skills
• Increased ability to identify suitable patients
