RFA vs EVLA treatment for varicose veins
Radiofrequency ablation (RFA) and endovenous laser ablation (EVLA) are two minimally invasive treatments used to effectively treat varicose veins, but what’s the difference?

What are Radiofrequency ablation (RFA) and endovenous laser ablation (EVLA)?
Radiofrequency ablation (RFA) and endovenous laser ablation (EVLA) are two minimally invasive treatments used to effectively treat varicose veins. Both procedures aim to close off problematic veins, preventing them from causing further symptoms and leading to their eventual absorption by the body.
RFA uses radiofrequency energy to generate heat within the vein. A thin catheter is inserted into the vein through a small incision, and once inside, the radiofrequency energy is delivered through the catheter, causing the vein walls to heat up, collapse, and seal shut. This treatment is performed under local anaesthetic, and most patients experience little discomfort, with a quick recovery time and minimal scarring.
EVLA works on a similar principle but uses laser energy instead of radiofrequency to achieve the same result. During EVLA, a laser fibre is guided into the affected vein, and when activated, the laser’s heat damages the vein walls, causing them to collapse and close off.
Like RFA, EVLA is performed under local anaesthetic and is considered highly effective for treating varicose veins. Both RFA and EVLA offer excellent outcomes with low risk of complications, making them preferred options over more invasive surgical treatments. These procedures allow patients to resume normal activities relatively quickly, with significant improvement in both the appearance of the legs and the symptoms associated with varicose veins.
What is the difference?
Although RFA and EVLA are very similar in terms of success rates at shutting down larger varicose veins, several studies have suggested that RFA may be associated with lower complication rates, so RFA is our preferred traditional endovenous method.
An even newer endovenous technique known as Venaseal™, however, is an exciting addition to our practice. The success rate of Venaseal™ is similar to both RFA and EVLA. However, it uses glue rather than heat to close the veins and is associated with even less discomfort.
What are the benefits of RFA treatment?
The benefits of RFA for treating varicose veins are numerous, making it a popular choice for both patients and doctors. RFA is minimally invasive, requiring only a small incision to insert a catheter into the affected vein. This results in less pain, minimal scarring, and a quicker recovery time compared to traditional surgical methods.
The procedure is typically performed under local anaesthetic, reducing the risks associated with general anaesthetic. RFA is highly effective, with a success rate of over 90%, and provides long-term relief from the symptoms of varicose veins, such as pain, swelling, and leg fatigue. Additionally, patients can usually return to their normal activities within a day or two, making it a convenient option for those looking for an effective and efficient treatment.

Why is RFA better than “laser” or EVLA?
RFA is considered better than EVLA for treating varicose veins in our practice because it’s generally a more comfortable experience and has a lower risk of complications.
RFA typically causes less post-procedural pain and bruising because it uses radiofrequency energy, which generates a gentler heat compared to the intense heat from laser energy used in EVLA. This can result in a smoother recovery with less discomfort for patients.
Additionally, RFA has a slightly lower risk of nerve damage, particularly in areas where veins are close to nerves, such as the lower leg. The procedure’s outcomes are highly successful and comparable to EVLA but with a more favourable side effect profile, making RFA a preferred option for many patients and clinicians.
Are there other options for varicose vein treatment?
Recently, we have introduced the Venaseal™ procedure. Venaseal™ is even less invasive because it avoids the use of heat altogether, which causes even less discomfort whilst still achieving excellent closure rates and long-term outcomes for patients.

Laser eye rejuvenation! Thank you to our lovely patient for allowing us to share her photos, just one week after her laser eyelid rejuvenation.
Crepe skin, loose skin, wrinkles are all common signs of ageing around the eye which do not respond well to surgery. The optimal treatment for these problems is laser resurfacing - which is exactly what this patient had.
We’ve been performing these treatments in the clinic for several years, although I’ve recently modified the technique to achieve incredible results with less downtime.

Here’s another fantastic result from our phenomenally talented plastic surgeon, @bramhallplasticsurgery .
As we age, the eyebrows naturally descend which allows excess skin to fall into the upper eyelids. The two main surgical options to address this are a brow lift, an upper eyelid lift (upper blepharoplasty) or both, but for many patients the most appropriate option is also the simplest: to leave the brows exactly where they are and address the excess skin at the eyelids alone.
Upper blepharoplasty is a straightforward procedure with scars hidden in the natural eyelid crease, making them very hard to see once healed. Brow lifts are usually more involved, often require a general anaesthetic, and tend to create a more noticeable change to the face.
The aim with upper eyelid surgery is subtle improvement - looking fresher and more rested, without it being obvious that you’ve had anything done.
This 42-year-old gentleman had a bilateral upper blepharoplasty under local anaesthetic and is shown here six months after surgery.

With darker evenings and fewer social engagements, January is a great time to think about treatments which benefit from a little down time or those that will deliver their best results by spring.
Here’s Dr Darren with his top recommendations for treatments to have over the winter months, including Sofwave, HALO, full-field resurfacing and varicose vein treatment, all of which will deliver beautiful results in time for the weather getting better and social calendars filling up!

Eye bags banished, jowls lifted, skin refined, veins gone. Thank you so much to all of our patients who have allowed us to share their photos with you and thank you to our incredible team who work so hard to take care of every patient who trusts us with their care.
Here’s to 2026 and another year of incredible transformations!
“But Daddies, WHEN is Santa coming? I want to wait up for him!”
Happy Christmas to all, and to all a good night 🎅🏻
Laser rejuvenation of the eye area can be an incredibly powerful tool for the right patients, especially those whose ‘bags’ are more about loose skin and fine lines, like this lovely patient here.
We treated her with full field ablation, which takes around 2 weeks to recover from. Her she is a few weeks later and you can see how much tighter the skin is, the crepey skin has gone and the fine lines have been ironed out. The patient is over the moon.

Eyelid surgery is one of the most popular procedures we do in the clinic. It’s a great fix for hooded eyes! Excess skin on the upper eyelids can not only create a hooded, heavy appearance but often affects the vision too.
Here’s the very talented @bramhallplasticsurgery discussing how upper eyelid surgery (blepharoplasty) can restore a more open, refreshed look by removing the excess skin and subtly redefining the natural eyelid crease. Scars are hidden within the fold of the eyelid, leaving eyes that look brighter, not “done.”

Thank you to our patient for allowing us to share her before and after photos of her upper blepharoplasty.
Excess skin on the upper eyelids can make the eyes appear tired or heavy. This simple procedure restores a lighter, more open look while keeping the result completely natural.
Another fabulous result from the very talented @bramhallplasticsurgery!
