How to Relief Contact Lens Dry Eyes? TheraLife Can Help

Contact lens dry eyes are very common.  The reason is even though a contact lens is designed to be biocompatible,  it disrupts the normal tear film and creates tear loss and evaporation.  Contact lens wearers are motivated by the convenience and better appearance.   Prolonged dry eye conditions left untreated can created cornea damage, which may eventually require cornea transplants or blindness.

The problem with contact lens-associated dry eye is well documented. The frequency of contact lens related dry eye is about 50 percent,  which means about 17 million of the 35 million contact lens wearers in the United States alone have dry eyes.  A study shos that almost 77% of people who wear contacts lenses will discontinue at one time or another due to comfort issues..

So what  kind of dry eye workup will your eye professionals do to diagnose dry eyes?

Dry Eye Work-Up
So often, customer come to their eye doctors complaining of dry eyes, and they indicate their eye doctors didn’t do any tests, or done a few and been told they have dry eyes.  What kind of tests should be done to diagnose dry eyes ?

1. Fluorescein staining of the cornea and conjunctiva, see if there are dry staining spots.

2. Tear Viscosity Test- also called “tear break-up testing”, lissamine green staining of the cornea and conjunctiva.  Dispersion of the dye measured by a stop watch measured in seconds.

3. Schirmers or phenol red thread testing, and evaluate the tear volume- responsible by la
crimal glands.  Normal Shirmer’s test value should between 15-20 mm

4. Dry Eye Questionnaire:

a.  How often do your eyes have symptoms of dryness? (Never; Sometimes; Often; Constantly)
  1. How often do your eyes have symptoms of scratchiness? (Never; Sometimes; Often; Constantly)
  2. Do you experience these symptoms in the company of smokers (pubs, clubs)? (Yes or No)
Treat Tear Deficiencies and Tear Film Stability:

TheraLife Eye Capsules- highly recommended for both lacrimal gland (tear volume) and meibomian gland dysfunctions (tear thickness) deficiencies.  TheraLife Eye works from inside out to normalize cell functions to both lacrimal and meibomian glands intra-cellularly so that you get balanced, sustainable tears all day long.   This formula is unique, and protected by patents.  Try it today!

Treat Ocular Surface- Mybomian Gland Dysfunction

Second, treat ocular surface problems.. For many patients, developing dry eye is a normal part of the aging process and contact lens wear only pushes them prematurely into this problem. Without a stable and healthy tear film, the patient will fail with contacts lens wear. Assess meibomian gland function as healthy meibomian glands are necessary for a stable tear film.
Recommended procedure here is to start lid scrubs and warm compresses to treat plugged meibomian glands and blepharitis. Reevaluate your treatment regimen in several weeks before considering changing the contact lens solution or material. Contact lens patients may well function acceptably with some modifications in the patient's tear film health and lid hygiene.

Preservative-Free Rewetting Agents-
Be aware that frequent use of eye drops (more than 3-4 times a day make your eyes drier.

The liberal use of artificial tears and drops to provide e temporary relief for dry eyes. . Regular use of rewetting agents (every two to three hours throughout the day) will make eyes drier.  If you ever noticed that after applying eye drops, you feel like putting more in within 10 minutes.  This is a sign you are over using eye drops, preservative free or not.

Advice is to decrease his contact lens wearing time and to use preservative-free tear drops frequently to improve his tear film no more than 3-4 times per day. Non-preserved tears eliminate the risk of the lenses adsorbing what may be toxic preservatives found in preserved artificial tears. Preservatives may disrupt the tear film, but they can also bind to deposits in the contact lens material, resulting in an imperfect surface over which tears will not flow smoothly. Therefore artificial tears and rewetting drops used by our contact lens wearers should be preservative-free.
