Title: LASIK, LASEK or PRK? How the Right Laser Technique Is Chosen
If you’re comparing LASIK, LASEK or PRK, you’re likely thinking about comfort, recovery and long‑term safety. At Panthagani, Professor Jesse Panthagani, consultant ophthalmologist in Northampton, will examine your eyes, your lifestyle and your goals. We will then recommend the technique that fits you.
Quick Answer
LASIK, LASEK or PRK can all correct short‑sightedness, long‑sightedness and astigmatism by reshaping the cornea (the clear front window of the eye). LASIK uses a thin “flap” and usually gives faster, more comfortable recovery. LASEK and PRK are “surface” treatments without a flap. They suit certain corneas, contact sports and dry eye, but are more uncomfortable for a few days and vision settles more slowly. The right choice depends on corneal thickness/shape, dryness, prescription and your activities. We confirm this after detailed corneal mapping at consultation.
LASIK, LASEK or PRK: what’s the difference?
All three use an excimer laser to gently reshape the cornea so light focuses more clearly. This can reduce your need for glasses for everyday tasks such as driving, screens and sport.
- LASIK (flap-based)
- How it works: A very thin corneal flap is created and lifted. The laser reshapes the tissue beneath. The flap is smoothed back into place.
- Comfort and recovery: Usually mild discomfort for a few hours. Vision often clears enough for desk work within 24–48 hours.
- Considerations: Very popular for its quick recovery. A flap is present, so we discuss any activities with a risk of eye impact.
- LASEK (surface)
- How it works: The surface skin (epithelium) is loosened and moved aside. The laser reshapes the cornea. The epithelium is repositioned and a protective bandage contact lens is placed.
- Comfort and recovery: More soreness or light sensitivity for 2–4 days. Functional vision builds over several days, with refinement over weeks.
- PRK (surface)
- How it works: The surface skin is gently removed rather than moved aside. The laser reshapes the cornea. A bandage contact lens is placed while the surface heals.
- Comfort and recovery: Very similar to LASEK — more uncomfortable at first. Vision improves over days and continues to settle over weeks.
Outcomes are comparable in the long term when the right technique is matched to the right eye. For more on what these procedures can treat, see our overview of laser eye surgery. You can also read the NHS guides to short‑sightedness and astigmatism for plain‑English definitions.
How we choose the right technique at your consultation
Your consultation with Professor Panthagani is thorough and unhurried. We map your corneas in detail (topography), measure thickness (pachymetry), check your tears and eyelid health, and confirm a stable glasses prescription.
Key factors that guide the choice between LASIK, LASEK or PRK:
- Corneal thickness and shape
- We must leave a safe “bed” of corneal tissue after treatment. Thinner or unusually shaped corneas often do better with a surface technique (LASEK/PRK) to protect long‑term strength.
- Prescription and optical zone size
- Higher corrections and larger night‑time pupils may influence the laser profile and the technique we recommend.
- Dry eye tendency
- LASIK can temporarily increase dryness because of the flap. If your eyes are already dry, LASEK/PRK may be the safer choice. We will also treat dryness proactively.
- Lifestyle and occupation
- If you play contact sports (rugby, martial arts) or have a job with a risk of eye trauma, a surface technique with no flap may be preferable.
- Past eye issues or scarring
- Old corneal scars, recurrent erosions or certain corneal patterns guide us towards one approach over another.
- General suitability
- Most good candidates are 21+ with a stable prescription for a year, healthy corneas and no active eye disease. Pregnancy and breastfeeding are times to wait.

Recovery, comfort and day‑to‑day life
- Immediately after surgery
- LASIK: scratchy or watery eyes for a few hours. Many patients are comfortable by the evening.
- LASEK/PRK: soreness, light sensitivity and watering for 2–4 days. We use pain‑relief drops and a bandage lens to help.
- Vision settling
- LASIK: usable vision often within 24–48 hours. Clarity continues to refine over 1–2 weeks.
- LASEK/PRK: functional vision builds over 4–7 days. Fine tuning continues for several weeks.
- Driving
- You may drive once your vision meets DVLA standards and you feel safe to do so. After LASIK this is often from day 1–2. After LASEK/PRK it is more often after the first review, typically about a week or longer. We will confirm for you individually.
- Work and exercise
- Desk work: often 1–2 days after LASIK; around a week after LASEK/PRK.
- Exercise: avoid swimming and eye makeup for at least two weeks; avoid contact sports longer. We will tailor this to your sport and healing.
- Night‑time effects
- Halos and glare can occur as the cornea heals, especially in the first weeks. These usually settle. We will discuss what to expect for your eyes.
Am I a good candidate?
A free video assessment is a helpful first screen, but only measurements in clinic decide. As a guide, you may be suitable if:
- You are 21 or older with a stable glasses prescription for at least a year.
- Your corneas are healthy and thick enough for safe reshaping.
- You have manageable dry eye and no active eye disease.
- You understand that while many people reduce their dependence on glasses, you may still need glasses for some tasks (especially close work after mid‑40s due to natural ageing).

When laser isn’t the best option
If corneal laser isn’t ideal — for example with very high prescriptions, thin or irregular corneas, or early lens changes — we will discuss:
- ICL (implantable contact lens): a tiny lens placed inside the eye to correct focus without reshaping the cornea. Read more about the implantable contact lens (ICL).
- Lens procedures (RLE): replacing your natural lens (similar to cataract surgery) to address focus and early lens ageing in one step. See our overview of lens procedures.
We will explain benefits, risks and realistic expectations for each, and help you weigh them against LASIK, LASEK or PRK.
What the day of surgery is like
- Numbing drops make the eye comfortable; you are awake but should not feel pain.
- The laser steps are quick — usually seconds of laser time and minutes in theatre.
- You go home the same day with drops and clear instructions.
- Follow‑up is arranged to check healing and confirm when you may drive or return to sport.

FAQs
Q: Which is “safest”: LASIK, LASEK or PRK?
A: When chosen well for the right eye, all three have strong safety records. LASIK offers rapid recovery but has a flap. LASEK/PRK avoid a flap, which some prefer for contact sports, but have more initial discomfort and slower visual recovery. Your corneal measurements and lifestyle guide the choice.
Q: Does laser eye surgery hurt?
A: During the procedure you feel pressure and touch but not pain, thanks to anaesthetic drops. After LASIK most people feel mild grittiness for a few hours. After LASEK/PRK there is more soreness for 2–4 days. We provide pain‑relief drops and clear aftercare.
Q: How soon can I drive?
A: You may drive once you meet DVLA vision standards and feel confident. After LASIK this is often from the next day. After LASEK/PRK it is usually longer (often about a week or more). We will confirm timing at your review.
Q: Will I still need glasses later?
A: Many people become much less dependent on glasses, particularly for distance. You may still need glasses for some tasks, and most people need reading help in their 40s and beyond due to the natural lens ageing process (presbyopia). Your consultation will set realistic expectations for your eyes.
