LASIK laser eye surgery has many benefits, including:

It works! It corrects vision. Around 80% of patients will have their desired vision after LASIK laser eye surgery. An enhancement can further increase this number.
LASIK laser eye surgery is associated with very little pain.
Vision is corrected nearly immediately or by the next day after LASIK laser eye surgery.
Recovery is quick and usually no bandages or stitches are required after LASIK laser eye surgery.
Adjustments can be made years after LASIK laser eye surgery to further correct vision.
After having LASIK laser eye surgery, most patients no longer need corrective eyewear.
What Are the Disadvantages of LASIK Laser Eye Surgery?
Despite the pluses, there are some disadvantages:

Changes made to the cornea cannot be reversed after LASIK laser eye surgery.
Corrections can only be made by additional LASIK laser eye surgeries.
LASIK laser eye surgery is expensive, typically costing $2,200 to $2,250 per eye; though compared to the cost of glasses and contact lenses, the price is reasonable.
LASIK laser eye surgery is technically complex. Problems may occur when the doctor cuts the flap, which can permanently affect vision.
LASIK laser eye surgery can cause a loss of "best" vision with or without glasses at 1 year after surgery. Your best vision is the highest degree of vision that you achieved while wearing your contacts or eyeglasses.
What Are the Potential Side Effects of LASIK Laser Eye Surgery?
Some patients experience discomfort in the first 24-48 hours after surgery. Other side effects, although rare, may include:

Glare
Seeing halos around images
Difficulty driving at night
Fluctuating vision
Dry eyes

The FDA has found no long-term side effects from LASIK laser eye surgery.

Healing after LASIK laser eye surgery usually occurs very rapidly. Most patients notice improved vision within a few days after LASIK laser eye surgery. However, your vision may be blurry and hazy for the first day. You should plan to have someone drive you home after LASIK laser eye surgery.

Your eyes will be dry even though they do not feel that way. Your doctor will give you prescription eye drops to prevent infection and keep your eyes moist. These eye drops may cause a momentary slight burn or blurring of your vision when you use them. Do not use any eye drops not approved by your ophthalmologist. Specific follow-up after the surgery varies from one surgeon to another. You will revisit the doctor for an evaluation 24-48 hours after LASIK laser eye surgery, as well as at regular intervals within the first six months after surgery.

My take, Don’t do it… Here’s the deal…

After getting operated by laser you eyesight will be perfect, yes, no doubt. But you never know when the side effects start, and 9 out of 10 they do. Your sight will get weaker than before, and as you said, you might even go blind. Its a slick chance… I know this because my dad (who’s a doctor) had undergone this Surgery when it was first started and after a few years his eyesight started blurring, now he has to wear two glasses, one for near and other for far, his eyesight is -7.5 for one eye and -8 for other… Which is very bad…

So you can take the risk as medical science has really evolved now… But why do it? Just wear a trendy spects or contact lenses… It doesnt make you look nerdy, unless you act like one!
