How Safe Is Laser Eye Surgery for People With High Prescriptions?

How Safe Is Laser Eye Surgery for People With High Prescriptions?

19 Dec 2025

When it comes to correcting vision impairments, laser eye surgery has emerged as a revolutionary solution. For individuals with high prescriptions, the question often arises: How safe is laser eye surgery? At Optimal Vision in London, we believe that understanding safety and effectiveness is crucial for those considering this transformative procedure.

Understanding Laser Eye Surgery

Laser eye surgery encompasses various techniques, including LASIK, LASEK, and the Implantable Collamer Lens (ICL). Each method aims to rectify vision problems like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

Why Choose Laser Eye Surgery?

  • Quick Results: Most patients witness improvements in their vision almost immediately after the procedure.
  • Minimal Discomfort: The surgery is relatively painless, with patients often expressing surprise at how quick and easy the process is.
  • Long-Lasting Results: With proper care, the results from laser eye surgery can last for many years, if not a lifetime.

Safety Factors for High Prescription Patients

Expertise of Our Surgeons

At Optimal Vision, our experienced team of eye doctors, including Dr Amir Mani, has completed over 50,000 refractive surgeries. Fear not; you’re in safe hands. Our specialised training allows us to assess the suitability of each patient thoroughly, particularly those with high prescriptions.

Precision Technology

We use state-of-the-art technology, including wavefront-guided laser systems. This advanced technology personalises each treatment, making it safer and more effective, especially for patients with high prescriptions.

Suitability Evaluation

Before recommending laser eye surgery, we conduct an extensive consultation. This evaluation examines the thickness of your cornea, the health of your eyes, and your specific vision needs. Given that individuals with high prescriptions may have unique corneal features, our careful assessments ensure a tailored approach.

Risk of Complications

As with any surgical procedure, there are inherent risks. For high prescription patients, the most common concerns include:

Dry Eyes: Temporary dryness is common after surgery, but our team provides treatments like LipiFlow to alleviate discomfort.
Visual Disturbances: Occasionally, patients may experience glare or halos around lights, especially at night. However, these usually diminish over time.

Experience and Aftercare

Our commitment to your safety extends beyond the procedure itself:

  • Comprehensive Aftercare: After your laser eye surgery, you will receive thorough follow-up care. We ensure you have access to all necessary medications and support.
  • Ongoing Assessment: Regular check-ups allow us to monitor your recovery and manage any arising issues effectively.

Frequently Asked Questions (FAQs)

1. Is laser eye surgery suitable for everyone with high prescriptions?
Not everyone is a candidate, but many individuals with high prescriptions can still undergo laser eye surgery. Factors like corneal thickness and overall eye health are assessed during your consultation.

2. Will I be awake during the surgery?
Yes, the procedure is performed with local anaesthesia, allowing you to remain awake. It takes only a few minutes per eye, and many patients find it to be an easy experience.

3. How long is the recovery period?
Most patients return to their daily activities within 24 to 48 hours. However, for complete recovery, it’s essential to adhere to aftercare instructions provided by our specialists.

4. What should I expect in terms of vision improvement?
Many of our patients achieve 20/20 vision or better following the procedure. However, individual results can vary based on factors like prescription strength and overall eye health.


5. Is there a risk of my vision deteriorating after surgery?
While laser eye surgery is highly successful, some patients may experience changes over time. This could be due to factors unrelated to the surgery itself, and routine eye exams can help manage these changes effectively.
