Differences Between Low-Level Light Therapy (LLLT) & Radiofrequency Therapy (RF)

Sep 26, 2025

Modern eye care has advanced beyond glasses, contacts, and drops. Today, innovative therapies such as Low-Level Light Therapy (LLLT) and Radiofrequency Therapy (RF) are used to treat conditions like dry eye disease and meibomian gland dysfunction (MGD). Both treatments are safe, non-invasive, and effective — but they work in different ways and aren’t suited for every patient. 

At Li & Liao Optometry, we want patients to understand the differences between these options so they can feel confident about which treatment may be right for them.

What Is Low-Level Light Therapy (LLLT)? 

LLLT uses gentle, medical-grade LED light to stimulate cellular activity and reduce inflammation. When applied around the eyes, it can improve the function of meibomian glands (responsible for producing the oily layer of tears) and relieve symptoms of dry eye. 

Benefits of LLLT:

  • Stimulates natural healing and reduces inflammation
  • Improves tear quality by restoring gland function
  • Comfortable, quick, and non-invasive
  • No downtime after treatment

Good Candidates for LLLT: 

  • Patients with mild to moderate dry eye disease
  • Individuals with meibomian gland dysfunction
  • Patients who prefer a drug-free, non-invasive option
  • Not ideal for: patients with pacemakers, implanted defibrillators, or other electronic \
  • hardware, as light-based therapy may interfere with these devices

What Is Radiofrequency Therapy (RF)?

Radiofrequency therapy uses gentle heat generated from radio waves to warm the eyelid tissue. This heat melts thickened oils in the meibomian glands, unclogs blockages, and encourages healthier tear production. It also stimulates collagen production, which can reduce eyelid laxity and improve skin tone around the eyes.

Benefits of RF:

  • Effective for moderate to severe meibomian gland dysfunction
  • Provides deep, targeted heat therapy
  • Can also improve skin elasticity and reduce eyelid wrinkles
  • Comfortable, in-office procedure with no downtime

Good Candidates for RF:

  • Patients with more advanced dry eye or significant gland blockages
  • Those who may not be suitable for LLLT due to pacemakers or other implanted devices
  • Patients interested in both eye comfort and cosmetic eyelid benefits

Which Treatment Is Right for You?

The choice between LLLT and RF depends on your eye condition, health history, and personal comfort. Some patients may benefit from a combination of therapies over time, while others may find one option clearly better suited to their needs.

At Li & Liao Optometry, we perform a thorough evaluation to determine:

  • The severity of your dry eye or gland dysfunction
  • Whether you have any medical implants or conditions that limit treatment choices
  • Your lifestyle goals (comfort, convenience, cosmetic benefits)
