Is it possible to see worse after laser eye surgery than before?

Laser eye treatment, such as LASIK or SMILE, is used worldwide to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. The procedure has been shown to be safe and effective, helping millions of people achieve clearer vision without glasses or contact lenses. But despite the high success rate, many patients wonder: Is it possible to see worse after laser eye surgery than before? In this blog post, we examine this question and explain what to expect during and after the procedure.

What happens during a laser eye treatment?

Laser eye treatment involves precisely reshaping the cornea to better focus light on the retina. This corrects refractive errors, and most patients experience a significant improvement in visual acuity after the procedure. The surgery itself is quick and usually painless. Most patients can resume their usual activities within a few days of treatment.

Is vision worse after laser eye surgery?

In most cases, laser eye surgery significantly improves vision. Complications that result in worsened vision are extremely rare. The likelihood that your vision will be worse after the procedure than before is minimal, especially when the treatment is carried out by an experienced surgeon. Nevertheless, there are some rare risks and side effects that can cause temporary visual disturbances:

1. Under- or overcorrection: In rare cases, the vision correction may be too weak or too strong, resulting in blurred vision. However, this can often be corrected with follow-up treatment.

2. Dry eyes: After laser eye surgery, some patients experience dry eyes. This can temporarily affect vision until the dryness is treated. In most cases, however, the symptoms resolve after a few weeks.

3. Light Sensitivity and Halos: After the procedure, some patients may notice increased light sensitivity or halos around light sources. These symptoms usually subside over time but may, in rare cases, persist.

What should you do if you experience vision problems?

If you notice visual disturbances after laser eye treatment, it is important to remain calm and contact your ophthalmologist or surgeon immediately. Most side effects are temporary and can be managed with proper aftercare. Your doctor will prescribe special eye drops to reduce inflammation and promote healing. During the first few days after treatment, you should also avoid bright light sources and wear sunglasses to protect your eyes.

How can you minimize risks?

Choosing an experienced and qualified surgeon is the most important step to minimize the risks of laser eye treatment. An experienced surgeon will perform a thorough pre-examination to ensure that you are a suitable candidate for the treatment. They will also use the latest technology to achieve precise and safe results.

In addition, you should carefully follow your doctor’s instructions both before and after surgery. Be sure to protect your eyes from external factors, and avoid rubbing them, as this can interfere with the healing process.
