DRY EYE SYNDROME

In dry eye syndrome, one or more of the tear components are missing or deficient and can result in:

  • Dryness
  • Burning sensation
  • Feeling of sand in the eyes
  • Gritty Sensation
  • Feeling of pressure or fatigue
  • Contact lens intolerance
  • Increased sensitivity to irritants
  • Poor Healing
  • Damage to the cornea
  • Damage to the conjunctiva
  • Increased chance of infection
  • Fluctuation in vision

THE BASICS

Tear Layer of the Normal Eye

Tears lubricate the surface of the eye. Contrary to the simplistic view depicted on the television, tears are a very complex substance.

  1. Mucin Layer: The mucin layer is a mucoprotein. It is the layer that touches the cornea and the conjunctiva. The mucin layer is the layer that is responsible for making sure that the tears are uniformly distributed across the surface of the eye. If the mucin layer is deficient, the tears will bead up after a blink just as water will bead up on the surface of a waxed automobile.
  2. Aqueous Layer: This is the water layer of the tear film. The aqueous layer is the bulk of the tear film.
  3. Oil Layer: The oil layer is the outside part of the tear film. It is the layer that is the furthest away from the cornea and conjunctiva. The oil layer protects the aqueous layer by reducing the speed at which the aqueous layer evaporates. This layer is made in the eye’s meibomian glands. Meibomian gland dysfunction is a common cause of dry eyes.
THE PUNCTUM

Puncta (plural of punctum) are little drains in your eyelids that carry away excess tears. The puncta drain tears away from the eye and into the nasal passages. Look at the inside of your lower eyelid about midway between the center of the eyelid and your nose to see one of your puncta, a little bump with a hole in it. There is one punctum on each of your four eyelids.

A patient with normal tear production would continuously need to wipe tears from their face if the puncta were not functioning.

For the tear deficient patient, the puncta, unfortunately, drain away what little tear film there is present, and leave the surface of the eye insufficiently lubricated.

SOLUTIONS TO THE PROBLEM

ARTIFICIAL TEARS COMMERCIAL EYE DROPS

We are bombarded daily with advertisements for artificial tears and drops that “get the red out.” You have learned that the tear film is a complex multi-layered substance that is not easily reproduced by commercially available products.

Not only do the commercial tear preparations fail to replace our lost tears adequately, but they also make matters worse by washing away what little tears you have. Almost all of the products on the market have preservatives in them in them. Preservatives are chemicals that keep the drops from becoming contaminated, but they are uniformly harmful to the surface of the eye. Some of them are only a mild problem, but others can produce severe damage to the cornea. The use of a preservative-free product eliminates the harmful effects of the chemicals but does not remove the washout effect.

Occasional use of a commercial artificial tear or redness reducing drop is acceptable, but regular use of these products may cause temporary or possibly permanent damage to the surface of the eye. Please limit the use of artificial tears to no more than four times per day. If you feel that you need to use them more often, you should consider other forms of dry eye treatment.

LUBRICANTS

You may use preservative-free lubricants. There are many acceptable lubricants on the market. Here is a short list. There are others that are also acceptable. Just make sure the container specifically states the product is preservative-free.

  • Daytime Treatmentseyedrop and ointment application techniques
    • Refresh Plus PF
    • Tear Naturals PF
    • Bion Tears PF
    • Moisture Tears PF
    • GenTeal
    • Hypotears PF
    • Theratears PF
  • Bedtime Treatments
    • Refresh PM
    • Duolube
    • Lacrilube
    • GenTeal Gel
    • Celluvisc

Keep in mind that you should only use lubricants sparingly. Overuse of any eye drop will deplete the eye’s naturally occurring nutrients.

Envision INMODE Lumecca Intense Pulse Light Treatment (IPL) and Forma Radiofrequency Treatment (RF)

Lumecca hand pieceINMODE Lumecca Intense Pulse Light treatment (IPL) works to control the inflammatory process and to stop the vicious cycle of inflammation and to reduce the need for medications. IPL treats ocular rosacea, meibomian gland dysfunction, and inflammatory dry eye. It has been shown to decrease demodex mites and bacteria around the eyelids. The powerful bursts of light also close off blood vessels that release inflammation in ocular rosacea. Lumecca is the most powerful intense pulsed light (IPL) designed to treat pigmented and vascular lesions. Lumecca-I uses photothermolysis, which provides a photofacialthrough the delivery of a comfortable light treatment. IPL has been FDA approved for more than 15 years to remove superficial skin lesions. Lumecca creates tissue heating which helps to reduce inflammation. During treatment there will be a bright flash of light and a sensation on your skin that feels like a light snap from an elastic band. Redness and a slight warming of the skin are normal after treatment and usually subside within an hour.

Forma Hand PieceINMODE Forma Radiofrequency treatment (RF) uses Radio-Frequency energy to generate heat which is applied to the skin around the eyes. This heat stimulates collagen formation, bringing white blood cells, and stem cells to the skin around your eyes while reducing inflammation. This treatment aids in opening up clogged meibomian glands, allowing for improved tear production and secretion. RF is usually followed by a meibomian gland expression. Forma feels like a warm massage in the eye area, improving blood circulation. The small size applicator and precision RF depth control allow for treatment in small and delicate areas.

Both IPL and RF reverse the signs of aging by stimulating collagen production by smoothing wrinkles and eliminate dark spots for younger looking eyes. All treatmentsare performed right in your physician’s office. As a result, there is no general anesthesia, no incisions, or downtime that is associated with excisional interventions. Most clients find the treatments very comfortable. Your physician will discuss in detail with you the specifics of your customized treatment plan and how it will address your individual condition.

Punctual Plugs

Your physician can perform a procedure that decreases the rate at which the puncta drain the tears from the eye. There are three ways to decrease tear drainage from the surface of the eyes:

  1. Temporary punctal plugs
  2. Permanent punctal plugs
  3. Permanent punctal occlusion

With these forms of treatment, there is no change in the rate of production of tears. Instead, there is a decrease in the drainage of the tears.

Punctal plugs are soft and pliable. Your physician can easily insert them in the puncta in a process that takes about 45 seconds and only requires a drop of local anesthesia to numb the area. Temporary plugs dissolve, but permanent plugs can last forever if they are not rubbed out by the patient. For the rare patient that does not like these plugs, they can be removed easily without anesthetic drops.

For the occasional patient with dry eyes in which the permanent plugs get rubbed out, the puncta can be occluded permanently. This is a straightforward five-minute procedure done in the office with local anesthesia to numb the area. This procedure is not easily reversed.

DRY EYE SYNDROME AND THE LASIK PATIENT

Dry eye syndrome occurs in nearly every LASIK patient. Recent ophthalmic literature states that dry eye syndrome occurs in 100% of LASIK patients. For that reason, we recommend temporary plugs for all LASIK patients to provide a smooth and nurturing tear surface for the critical week or two following the procedure. An occasional LASIK patient will find the week or two not adequate and will need permanent plugs inserted after the temporary plugs have dissolved.
