Frequently Asked Questions

LASIK has been performed internationally for approximately 15 years. It was first performed in clinical trials in the U.S. in 1995. It is important to note that the major components of the procedure have a long history. Ophthalmologists have been reshaping the cornea for over 50 years, creating a protective layer of tissue for over 35 years, and using the excimer laser since the 1980s.

LASIK is a surgical procedure that permanently removes corneal tissue to reshape the eye in order to improve refraction. The physical results are permanent. However, you should be aware that since the eyes can still change with time, and LASIK does not affect a number of visual conditions associated with age. For example, LASIK does not prevent presbyopia or affect this condition once it does occur.

Depending on the cause, retreatment may be a viable solution to vision changes later in life, and other treatment options exist. You would need to see your eye doctor to determine the cause of the change and to determine which option is best for you.

Fast visual recovery characterizes this operation. Most patients achieve good vision the day of surgery and find that their eyes feel fairly normal within a day. However, vision can continue to improve, and best vision can still take two to three months to occur. If necessary, adjustments to the surgery called enhancements can be done. Patients who undergo hyperopic LASIK often need to wait longer to able to see clearly. Typically, they are unable to see with intense clarity for one or two weeks, with best vision coming in several months post-operatively.

Most patients who have LASIK do not need to wear glasses for their daily activities. However, patients may need to wear reading glasses if they are over the age of 40. This is caused by the normal aging of the eye known as presbyopia. This condition occurs with or without LASIK. Some patients may need a minimal prescription for some activities. Those patients who currently have bifocals will still need reading glasses after the surgery unless they opt for a treatment plan called monovision, wherein one eye is corrected for distance and the other for near vision.

Patients are given a topical aesthetic (eye drops) to numb the eye, so they experience no pain during the procedure. When the surgeon applies the vacuum ring, the patient experiences a sensation of pressure just before his or her vision fades for a few seconds. For several hours after the procedure, many patients describe a mild burning sensation, such as after opening the eyes while swimming in chlorinated water. Therefore, taking a nap for the first 2 to 3 hours after LASIK is encouraged. After the first few hours, this uncomfortable feeling usually subsides.

You can have bilateral simultaneous LASIK (both eyes done at the same time). In fact, the practice is common. However, in some circumstances, surgeons or patients will determine that it is best to wait between eyes in order to evaluate the results. Hyperopic LASIK patients do not experience the extremely fast visual recovery that myopic patients do. Therefore, some surgeons prefer to operate on their eyes separately. Patients should discuss their options with their eye doctor.

It depends on your occupation. Certain jobs that require intense clarity of vision (dentistry and surgery, for example) may be difficult to perform for one or two days. Most patients can return to work the next day, assuming their vision is adequate for their job. However, some people may feel fatigued for a day or so following surgery.

You can resume most normal activities immediately after surgery. However, for at least a few days you will need to avoid activities that would cause perspiration to run into the eyes. You should wear safety glasses while playing contact sports whether or not you have had surgery. But if you do not routinely wear safety glasses, your surgeon may recommend wearing them for at least one month after LASIK. You will also need to avoid such activities as contact sports and swimming for several weeks. It is important to talk specifically with your doctor about limitations on activities after LASIK.

Although LASIK is not a cosmetic procedure, it is considered an elective surgery. Most policies will not cover the procedure, nor will Medicare usually cover it. You should check with your insurance company to see if your policy offers partial or full coverage. In many cases, the cost of the procedure can be covered by medical flex plans or health savings accounts that allow pre-tax dollars to be set aside for medical expenses. You should check with your employer to see if your company offers this type of benefit. It is possible that the cost of LASIK may be deducted from your U.S. federal income taxes. You should check with your accountant to see if you can take LASIK as a credit. deductible health expense. Many ophthalmologists in the US also offer financing plans to their patients.
