Do you understand possible side effects and complications?
While complications that result in a loss of vision are rare, certain side effects, particularly dry eyes and temporary visual disturbances, are fairly common. But these usually resolve after a few weeks or months, and very few people consider them to be a long-term problem.
Dry eyes. LASIK surgery causes a temporary decrease in tear production. For the first six months or so after your surgery, your eyes may feel unusually dry as they heal. Even after healing, you may experience an increase in dry eye symptoms. Your eye doctor might recommend that you use eye drops during this time. If you experience severe dry eyes, you could opt for another procedure to get special plugs put in your tear ducts to prevent your tears from draining away from the surface of your eyes.
Glare, halos and double vision. After surgery you may have difficulty seeing at night. You might notice glare, halos around bright lights or double vision. This generally lasts a few days to a few weeks, but it can also become a chronic problem.
Undercorrections. If the laser removes too little tissue from your eye, you won't get the clearer vision results you were hoping for. Undercorrections are more common for people who are nearsighted. You may need another refractive surgery (called an enhancement) within a year to remove more tissue.
Overcorrections. It's also possible that the laser will remove too much tissue from your eye. Overcorrections may be more difficult to fix than undercorrections.
Astigmatism. Astigmatism can be caused by uneven tissue removal. It may require additional surgery, glasses or contact lenses.
Corneal ectasia. Corneal ectasia is one of the more-serious complications and occurs because of progressive myopia due to steepening of curvature of the cornea.
Flap problems. Folding back or removing the flap from the front of your eye during surgery can cause complications, including infection and excess tears. The outermost corneal tissue layer (epithelium) may grow abnormally underneath the flap during the healing process.
Vision loss or changes. Rarely, you may experience loss of vision due to surgical complications. Some people may also not see as sharply or clearly as previously.

嘘，笑得矜持些！400度生活就不能自理了，估计0度的时候自理的也不怎么样
大约是98年左右，深圳和上海各有一家从俄罗斯引进的手术治疗近视的医院。我当时被单位指派去俄罗斯谈判引进俄罗斯医生开国内第三家近视眼手术门诊。在莫斯科医院显微镜下全程观摩了手术过程。
基本原理是在眼球表面用手术刀（特殊设计的手术刀可以精确到控制划痕深度）刻画出一定形状的划痕，愈合后由于划痕有一定的张开而改变了形状（改变了眼球的焦距）。后来这两家门诊都有一些医疗纠纷，关门大吉。我们的项目也被第一起医疗事故给吓停了。
我猜想，激光治疗近视原理是一样的。不过是精确的激光控制代替了人手控制的手术刀。
理论上，眼镜矫正效果较好的，长期稳定的情况都可以作。
但是我觉得不适合青少年或者还在发展的人。另外高度近视应该在手术前仔细检查视网膜病变（脱落，破裂）
任何少于20年历史的医疗技术（包括疫苗，药物，和手术矫正等）都有一定的潜在风险。虽然可能当时的效果很好。
