Therapies & Procedures for Dry Eye: A Guide for Patients & Families

by

For many moderate to severe dry eye patients, symptoms are manageable at first, then progressively worsen. The process may be gradual or sudden. The research community, despite its ongoing work, has not yet identified the primary “mechanism of action” for many cases of severe dry eye.  

This unpredictability raises a dire predicament for patients who rely on self-care remedies to mitigate symptoms. Fortunately, physicians have developed more aggressive treatment methods for severe cases. 

In this article, we’ll provide an overview of the five most common therapies and procedures for moderate to severe dry eye patients. Though our views are not intended to replace the advice of your physician, we hope this article gives you a good place to start. 

Punctal Plugs (Punctal Occlusion Surgery) 

Your tears are always being produced and always being drained. Drainage of the tears occurs through four small drains (the “puncta”). You have a puncta on each upper lid and a puncta on each lower lid. If you are not producing enough tears (or if they are evaporating too fast), these puncta can be plugged (much like plugging a drain) allowing for increased tear retention.

Punctal plugs are an advanced dry eye treatment that blocks the eyes’ tear drainage system by inserting devices called “punctal plugs” into the tear ducts or “puncta.” The procedure aims to preserve natural tears on the surface of the eye.1

  • Non-surgical assistance for tear deficiency 
  • In-office procedure

Benefits of Punctal Plugs 

Punctal plugs come in different sizes and are made from different materials, from collagen to silicone.1 

Collagen plugs are inserted first. Over the course of 4–7 days,  if the procedure shows signs of success, silicone plugs can be inserted for long-term treatment.1 

In most cases, the puncta on the lower lid are occluded, and in advanced cases, both the upper and lower lid puncta are occluded. 

How To Know If Punctal Plugs Are Right For You

Punctal plugs are a non-surgical procedure, but dilation of the puncta to allow insertion can be uncomfortable, so topical anesthesia is usually used. You should feel pressure, but no pain with topical anesthesia. 

In inflammatory dry eyes, there is some concern that inflammatory chemicals and particles will not drain from the ocular surface properly with the use of plugs. Much like a backed up sink, if these substances accumulate, irritation and inflammation can actually increase — negating many of the benefits of tear retention.

Of course, we recommend that you consult with your doctor to discuss the pros and cons of punctal occlusion therapy. 

Autologous Serum (AS) Eye Drops 

Autologous Serum (AS) Eye Drops are a highly-effective – but costly – alternative to artificial tears. 

In a complex process, this “autologous serum” is created from a blood sample supplied by the patient. The result is an eye drop which is a near carbon copy of the patient’s natural tears.2

Quick Facts

  • Specialized lubricant for ocular health
  • Costly and lengthy formulation process
  • Not covered by most health insurance (No FDA approval)

Benefits of Autologous Serum (AS) Eye Drops 

Artificial tears and other over-the-counter remedies help lubricate and ease symptoms, but they do not contain the vitamins, proteins, lipids, and growth factors necessary for eye health.

Autologous serum eye drops, meanwhile, carry biological nutrients found in natural tears that are critical to the maintenance of the tear film.3 As eye drops also help to fight inflammation, ensuring patient comfort.4

Scleral Contact Lenses

Scleral lenses are specially-designed contact lenses for patients recovering from corneal damage, as well as for patients suffering from severe dry eye syndrome. 

Quick Facts 

  • For patients with severe dry eye or corneal damage
  • Custom-fit to a patient’s eyes for comfort 
  • May cost up to $4,000 for fitting and lenses 

Benefits of Scleral Lenses 

More studies examining scleral lenses and dry eye syndrome are needed. Still, researchers have called scleral lenses, “a viable option for severe dry eye syndrome,” that “improve visual acuity and relief of symptoms.”5 

Standard contact lenses may contribute to dry eye symptoms, or due to dryness, require that dry eye patients take special care to remove them safely. 

Eyelid Thermal Pulsation Technology

Eyelid thermal pulsation therapy relies on a unique device that simultaneously applies heat (thermal) and pressure (pulsation) to open and express the clogged glands. 

Quick Facts

  • Applies heat and pressure to relieve symptoms of MGD 
  • FDA-approved & non-invasive
  • Short, 12-minute procedure6 

Once the hardened meibum is softened and removed, meibomian glands are then free to produce a healthy layer of oil and lipids, preventing tear evaporation.

Intense Pulsed Light (IPL) Therapy

Intense Pulsed Light Therapy, or IPL, is a well-documented and effective procedure for symptoms related to meibomian gland dysfunction. 

IPL works by directing a controlled spectrum of light to close the blood vessels that supply the glands in the eyelids, stimulating healthy gland function.7

Quick Facts

  • In-office procedure
  • For evaporative dry eye (meibomian gland dysfunction) 
  • A safe and effective treatment for rosacea

Benefits of Intense Pulsed Light (IPL) Therapy

IPL decreases inflammation in the eyelids and ocular surface and promotes the production of healthy lipids that block tear evaporation.8

Over the last five or so years, IPL has become a go-to procedure for people suffering from chronic dry eye caused by meibomian gland dysfunction. In one study from the Mayo Clinic, 89% of patients who tried IPL saw improved dry eye symptoms.7

Four Lifestyle Changes For Healthier Eyes 

  1. If the air in your home is dry, try a humidifier. Avoid ceiling fans, and certainly don’t sleep with a ceiling fan on.
  2. Move your car’s AC vents so that they blow away from your face. 
  3. Use sunglasses outdoors, and make sure the lenses are large enough to cover your eyes. 
  4. Take breaks when reading or using your computer or phone. Try for at least a 20-second break after every 20 minutes looking at a screen.9
