Lasik surgery is a preferred surgery for removing glasses. It is very beneficial for those who are tired of wearing glasses, have high power, or find it cumbersome and costly to use contact lenses. It is a refractive eye surgery that helps improve the vision in people with myopia, hyperopia, and astigmatism. Complications during surgery are very rare. Side effects are few and temporary.

Laser eye surgery is the most preferred eye surgery by people across the world. It has a high success rate. However, there are certain risks, such as dry eyes and glare, halos, or double vision, which are common and clear up within a few weeks or months. Other risks involved are,
- Under corrections, where the laser removes lesser tissue from the eye.
- Overcorrections, where the laser removes too much tissue.
- Astigmatism due to uneven removal of tissue.
- Regression, where the vision goes back to the original prescription.
- Flap problem, caused by the removal of the flap from the front of the eye,
- And, in rare cases, vision loss.

Retinal detachment is when the retina, which is a thin, light-sensitive membrane at the back of the eye, pulls away from its original place. This causes total or partial vision loss. Although no exhaustive studies prove any relationship between Lasik surgery and retinal detachment, there may be some connection between the two. This is because patients with myopia have thinner retinas that make them susceptible to tears during laser surgery.

Despite its advantages for most people, Lasik surgery has some disadvantages, too. As technically it is a complex surgery, some rare problems could occur, where the doctor could accidentally create a flap, which might affect the vision permanently. Furthermore, there are possibilities of side effects of the surgery, some of which may take a few months for you to recover from. Some risks involved, such as under-correction or overcorrection, may require another procedure within a year.

Laser-assisted in situ keratomileusis or Lasik surgery is a corrective surgery that can improve vision. It involves permanently reshaping the tissue in the front of your eye, which lasts for a lifetime. However, as vision tends to deteriorate as part of your natural ageing process, some patients may experience blurriness or changes in vision. So, the length of time for which the effect of lasik lasts depends on the age at the time of the Lasik surgery or any other prevalent eye conditions.
