Yes, while LASIK is generally safe and effective, complications can occur. Although rare, potential issues exist.
Potential Complications of LASIK
Several factors can lead to complications following LASIK surgery. These range from minor inconveniences to more serious issues:
- Weakened Eye: LASIK weakens the eye, increasing vulnerability to injury, particularly during the first year post-surgery. [Source: Checkbook.org]
- Infection or Irregular Healing: Infections or problems with the healing process can cause complications. [Source: Checkbook.org]
- Corneal Neuralgia: This rare complication involves nerve pain in the cornea. The risk is generally low and unpredictable. [Source: Reddit r/lasik]
- Flap-related problems: Issues related to the corneal flap created during the procedure can occur. [Source: OCL Vision]
- Incorrect Refraction: Improper reshaping of the cornea can lead to blurred vision, often correctable with glasses or contacts, or potentially requiring further corneal reshaping. [Source: Mayo Clinic]
Frequency of Complications
While serious complications are infrequent (less than 1%), a significant percentage of patients (around 30%) may experience temporary side effects. [Source: American Refractive Surgery Council, The Guardian] Studies indicate that over 90% of patients achieve 20/20 vision or better immediately after surgery, but long-term results may vary. [Source: Checkbook.org] It's crucial to remember that "going wrong" can encompass a spectrum of outcomes, from minor vision fluctuations to rarer serious problems.
Minimizing Risks
Careful patient selection and experienced surgeons significantly reduce the risk of complications. Thorough pre-operative evaluations are essential.
