After a small amount of online research from LASIK knowledge bases it seems that there is no concrete evidence on this subject. Although this issue has been acknowledged no studies have been made on the any possible pro's or con's. The minimal advise is that you should refrain as much as possible from introducing THC into your body one week prior and three weeks post. That however is not necissarly good advise. Optomitrist recomendations, from several sources would state to allow one month for THC to completely clear your system prior to any eye surgery. Post surgery it is advised to introduce no THC into your system until the end of your healing period. The average healing period is different for each type of corrective eye surgery (LASIK, PRK, Wavefront, ect.) Pertaining for LASIK, depending on which type of LASIK you choose, the healing period is a minimum of 3 months for standard LASIK, and 6 months for custom LASIK.
Lamens.
Any experienced smoker knows you will occasionally suffer from red eyes or dry eyes. Common sense will tell you that altering the natural state of your body will have an affect on your body. Being that your eyes suffer trauma through the surgery it is in your best interest to allow your eyes to remain as natural as possible. There are no confirmed benefits to THC and the healing process of the eye.
Vasodilation.
Widening of blood vessels resulting from relaxation of the muscular wall of the vessels
Vasodilation is a symptom from THC in the blood stream. It is the cause of red eyes, and cottomouth. Pertaining, it can be assumed that widening the blood vessels in your eyes will slightly change their shape. Most cells in your body are no further than two cells away from a part of your circulatory system. One of this systems use is to fuel your cells. This poses two major concerns. One, every cell in your eye is altered in location, shape, or pressure. While healing, this can cause your cornea to heal differently than expected. That would have a direct inpact on portions of your vision. Two, it can be assumed that the cells in your eyes may receive to much, or not enough of what they need to survive and heal.
In Summary.
It would be my advise to clear your system of THC prior to surgery, and to not introduce any THC into your system until your healing process is complete. Eye surgery is a decision you will live with for the rest of your life. Consider sacifricing certain habits the same way you have in the same way you are sacrificing the large ammount of money you would for this surgery.
Smoking is never a good idea, but there is not specific harm in smoking after LASIK surgery. It may be a good time to stop smoking since you are now improving your vision and your life, why not stop smoking and enjoy this benefit as long as possible?
