LASIK Contraindications: Reasons for NOT Having LASIK

LASIK Contraindications: Reasons for NOT Having LASIK

The introduction of LASIK to human civilization heralded a new era for those who have long been suffering from eyesight conditions such as astigmatism, nearsightedness, and farsightedness. The ads for LASIK make it seem so cheap and so easy, that most are lulled into the false sense of security that they can get the procedure anytime, anywhere. The truth is that every LASIK patient undergoes screening to ascertain if they are fit to have the procedure or not. This is also for the benefit of the patient – having the operation might bring more problems if you are not fit to have it. These contraindications, or reasons that prohibit a prospective patient from undergoing the procedure, are discussed below.

There are actually two types of contraindications: absolute contraindications, and relative contraindications. The former are very strict conditions; if you have been found to have an absolute contraindication then you must not, under any circumstance, go on with the procedure. Relative contraindications are more relaxed. If you have been found to have this sort of contraindication, you may still proceed with the operation, but your physician or surgeon will take note of your condition and he or she may alter the treatment plan or procedure slightly. You will still have a high chance of success, but the results are relatively unpredictable as compared to patients who have no contraindications at all.

1. Thickness of the cornea. The procedure requires a certain amount of thickness of the cornea. LASIK involves altering the shape of the cornea, thus, if it is too thin, the physician will advise you not to go on with the operation because there might not be enough corneal tissue left that have not been altered. It could create more problems after the operation than before.

2. Health Condition. Some illnesses, such as diabetes, may be absolute or relative contraindications that may discourage the patient from having LASIK. The procedure requires the patient to have healthy levels of blood sugar for prolonged periods of time so as to facilitate healing.

3. Other eye conditions. The beginnings of the development of cataracts or lens clouding are considered to be absolute contraindications for LASIK because these conditions will only worsen over time, thus rendering the operation futile. Patients who are undergoing treatment for glaucoma are also discouraged from having the operation.

4. Eye Dryness. LASIK vision correction requires a prospective patient to have the capability to generate a sufficient amount of tears, so that their eyes can heal properly. People who have worn contact lenses for prolonged periods of time, take certain medication, or have other health conditions may have dry eyes as a result. For those that have these dry eye conditions they may want to look for other options because these are relative contraindications to LASIK.
