Yes, laser eye surgery can go wrong, although serious complications are rare.
While laser eye surgery boasts a high success rate, like any surgical procedure, it carries potential risks and complications. The likelihood of experiencing a significant visual loss complication is low, estimated at around 1 in 10,000. However, the risk of needing further treatment for complications that do not result in significant vision loss is higher, estimated at about 1 in 1,000.
Potential Risks and Complications:
- Dry Eye: This is a common side effect, usually temporary, where the eyes don't produce enough tears.
- Halos and Glare: Some patients experience halos or glare around lights, particularly at night. This usually diminishes over time.
- Undercorrection or Overcorrection: The laser may remove too little or too much tissue, requiring further correction.
- Astigmatism: This occurs when the cornea is not perfectly spherical after surgery.
- Ectasia: A rare but serious complication where the cornea weakens and bulges.
- Infection: As with any surgery, there's a risk of infection.
- Flap complications (LASIK): Issues related to the corneal flap created during LASIK surgery, such as displacement.
Factors Influencing Risk:
- Patient's Individual Eye Health: Pre-existing conditions can increase risk.
- Surgeon's Experience and Skill: Choosing a qualified and experienced surgeon is crucial.
- Technology Used: Newer technologies often offer greater precision and reduced risk.
- Adherence to Post-Operative Instructions: Following your surgeon's instructions carefully is essential for proper healing.
Minimizing Risks:
- Thorough Pre-Operative Evaluation: A comprehensive eye exam is crucial to determine candidacy and identify potential risks.
- Choosing an Experienced Surgeon: Research surgeons' qualifications, experience, and complication rates.
- Utilizing Advanced Technology: Inquire about the latest laser technology used by the clinic.
- Realistic Expectations: Understand the potential benefits and risks before proceeding.
- Following Post-Operative Care Instructions: Adhere strictly to your surgeon's instructions for aftercare.
Ultimately, while the risk of significant complications from laser eye surgery is low, it's not zero. A careful assessment of your individual risk factors, a discussion with a qualified surgeon, and realistic expectations are essential for making an informed decision.
