The procedure is very low risk. However, as with any surgical procedure, there are potential complications. Vision-threatening complications do exist, but they are extremely rare. These include infections (a statistical incidence of 1 in 5,000) and irregular healing processes that can lead to something called “irregular astigmatism” that glasses cannot correct, and contact lenses or further surgery may be required to improve. There are also potential complications which may lead to temporary blurriness, temporary dependence on glasses or contact lenses, or a need for additional surgery. In most cases, the patient can still do well and recover with good vision.
For this reason, LASIK patients should confirm the experience of their surgeon to determine if they have specialized training in cornea surgery. Because LASIK is performed on the cornea, knowledge of the healing properties of the cornea and management of any complications are critical to the patient’s well-being. Knowing how to handle a complication should one occur can make a significant difference in the patient’s outcome.
