Informed Consent

Dear Patient,

This informed consent document contains information that will:

  • Inform you about the stimulation technique of the Meibomian glands through OPE® and LIGHT MODULATION® technologies;
  • Verify the absence of contraindications related to the use of those technologies.
  • If all conditions are met and after your informed consent, the Optometrist may proceed to with the treatment.

The Treatment:

OPE®: it is a polychromatic light which, thanks to thermal pulses, stimulates the meibomian glands to resume their normal activities.   The light pulses are applied to the periorbital (area near the eye) and cheekbone, it stimulates the contraction of the glands by increasing the lipid (oil) stream and thereby reducing the evaporation of tears.

LIGHT MODULATION® is a unique technology of photobiomodulation (PBM) used for many years in various fields of medicine (dermatology, dentistry, etc.). The emission of a particular light at a certain wavelength triggers an endogenous (internal) heating of the eyelids. This treatment facilitates the liquefying of the oils from Meibomian glands


The treatment is contraindicated in the following cases:

  • Pregnancy
  • Epilepsy
  • In the presence of metallic piercing on the treated area
  • Use of photosensitizing drugs
  • History of cancer in the area of treatment
  • Those who have used isotretinoin (Roaccutane) within the last year (used for treating severe acne)
  • Active cold sores or herpes simplex or herpes zoster virus
  • History of keloids
  • Use of any photosensitive medications or herbal supplements
  • Psoriasis, vitiligo or warts, lupus or connective tissue disorder
  • Botox and dermal filler treatment having taken place 1 week prior to treatment and 2 weeks after treatment
  • Fitzgerald skin type four (darker skin has risk of depigmentation).
  • If taking medications such as anti-inflammatories, anticoagulants, antibiotics and antihistamines, please notify your Optometrist.

Risks and Possible Complications

OPE® – like any other treatment of pulsed light, may have some side effects; the most common complications include:

  • transient erythema (redness),
  • transient itching and edema (swelling),
  • transient hyperpigmentation/hypopigmentation (temporary lightening or darkening of skin in the treated area).
  • The equipment emits a strong intensity light which may cause, if not properly protected, temporary eye disorders. For this reason, the patient should wear the protective goggles provided by the Optometrist during the OPE/IPL treatment procedure.

Prior to Treatment

  • Avoid significant sun exposure, tanning beds or tanning cream for 3-4 (minimum 2) weeks prior to treatment;
  • Do not perform chemical, physical or enzymatic peels before and during the period of treatment with light technology.
  • Avoid harsh scrubs, acids, benzoyl peroxide, Retin-A.
  • Do not take photosensitizing drugs, or if essential, refrain from informing the Optometrist.
  • If taking medications such as anti-inflammatory, anticoagulants, antibiotics and antihistamines, please notify the Optometrist.

If you wear contact lenses, you should remove them before starting the treatment.

After Treatment

  • After the treatment some slight redness may appear.
  • The clinician will apply soothing Aloe Vera face cream.
  • Don’t have any aesthetic medical procedures on the treated areas (but in general on the entire face) for the duration of the treatment phase.
  • Wear sunglasses for 15 days after each session when outdoors.
  • Apply sun block (between factor 30 – 50) over the skin around the eyes and cheeks.
