Everything You Need to Know About Laser Eye Surgery
Considering laser eye surgery? We’ve compiled answers to the most common questions to help you make informed decisions. Whether you’re curious about eligibility, the recovery process, or long-term results, this FAQ section covers it all — clearly and confidently. Backed by expert insights from Precision Vision London, your vision is in trusted hands.
1. What exactly is Laser Eye Surgery?
Laser Eye Surgery is a procedure that reshapes the cornea (the clear front part of the eye) using a precise laser to correct refractive errors like short-sightedness (myopia), long-sightedness (hyperopia), and astigmatism. This improves vision, reducing or eliminating the need for glasses or contact lenses.
2. What’s the difference between LASIK and LASEK/PRK?
– LASIK: A thin flap is created, and the laser reshapes the cornea underneath. Recovery is fast (1-2 days).
– LASEK/PRK: The outer layer is gently removed (no flap), and the laser treats the surface. Recovery takes longer (5-7 days).
3. Am I suitable for Laser Eye Surgery?
Most people with stable vision prescriptions (unchanged for 1+ years), healthy eyes, and no underlying medical conditions (e.g., severe dry eye, keratoconus) are good candidates. A full consultation will determine eligibility.
4. Is there an age limit for Laser Eye Surgery?
The minimum age is 18 (when vision stabilizes). There’s no strict upper limit, but after 45, presbyopia (age-related near-vision loss) may require Lens Replacement or reading glasses.
5. Can I have Laser Eye Surgery if I have astigmatism?
Yes! LASIK, LASEK, and SMILE can all correct astigmatism.
6. What types of Laser Eye Surgery does Precision Vision London offer?
We offer:
• LASIK (flap-based, quick recovery)
• LASEK/PRK (surface treatment, suitable for thinner corneas)
7. Can Laser Eye Surgery correct presbyopia (age-related reading vision loss)?
Yes, PRESBYOND® Laser Blended Vision adjusts one eye slightly for near vision while the other focuses on distance, reducing dependency on reading glasses.
8. How long does the actual laser treatment take?
The laser itself takes 10-30 seconds per eye, but the full procedure (prep, laser, recovery) takes 10-15 minutes per eye.
9. Is Laser Eye Surgery painful?
No—numbing drops are used, so you only feel slight pressure. Some patients report mild discomfort (like an eyelash in the eye) for a few hours afterward.
10. Will I be awake during the procedure?
Yes, but you’ll be given mild sedation (not general anaesthesia) to keep you relaxed.
11. How stable does my vision prescription need to be?
Your glasses/contact lens prescription should be unchanged for at least 12 months.

12. What factors might make me ineligible for Laser Eye Surgery?
- Thin or irregular corneas
- Unstable vision prescription
- Severe dry eye syndrome
- Autoimmune diseases (e.g., rheumatoid arthritis)
- Pregnancy or breastfeeding
13. Can I have surgery if I have dry eyes?
Mild dry eyes may be treated before surgery. Severe cases may disqualify you—this is assessed in consultation.
14. Can I have Laser Eye Surgery if I’m pregnant or breastfeeding?
No—hormonal changes can affect vision stability. Wait 3-6 months after breastfeeding ends.
15. What tests are involved in the consultation and assessment?
- Corneal topography (mapping)
- Pachymetry (corneal thickness)
- Wavefront analysis (custom treatment plan)
- Pupil dilation (checking retina health)
16. How long does the initial consultation take?
About 90 minutes, including scans and discussion with your surgeon.
17. Do I need to stop wearing contact lenses before the consultation/surgery?
Yes:
- Soft lenses: Stop 1 week before.
- Rigid (hard) lenses: Stop 4 weeks before.
18. What are the potential risks and complications?
- Dry eyes (usually temporary)
- Glare/halos at night (improves over weeks)
- Under correction/overcorrection (rare, may need enhancement)
- Infection (extremely rare with proper aftercare)
19. How common are serious complications?
Very rare (<1% with modern lasers and expert surgeons).
20. What are the most common side effects?
- Mild dryness (3-6 months)
- Light sensitivity (1-2 days)
- Temporary blurred vision (first 24 hours)
21. How effective is Laser Eye Surgery? What are the success rates?
- 98% of patients achieve 20/40 vision or better (driving standard).
- 90% achieve 20/20 or better.
22. Is Laser Eye Surgery permanent? Can my vision regress?
Yes, it’s permanent, but age-related changes (e.g., presbyopia, cataracts) may affect vision later.
23. Will I still need reading glasses after surgery?
If you’re over 45, you may need PRESBYOND® or reading glasses for close-up tasks.
24. Can Laser Eye Surgery cause blindness?
No—modern lasers have safety mechanisms, and complications leading to blindness are exceptionally rare.
