Dry Eye Conditions

Dry eye or Dry Eye Syndrome is a very common condition that increases with age and probably affects 2 million people in the UK – usually more women than men. Dry eye occurs when people don’t have either enough tears, or the correct composition of tears, on the surface of their eyes to lubricate the eyes and keep them comfortable. For some this can be a maddening condition that can frustrate as much as it does irritate.

What is Dry Eye?

Centre for Sight are constantly looking to find new ways to tackle dry-eye, and one of only a few centres is Europe to have the Lipi-Flow system to treat Meibomian gland disease. While not suitable for all we have many options that can help relieve the sufferer.

The tear film is composed of three layers.

Each component layer is dependent on the other for proper function. The outer oily layer of the tear film is produced by the meibomian glands in the eyelids and reduces evaporation of the tears. The thick middle watery layer is made by the lacrimal gland above the upper eyelid and washes away irritants. The inner mucus layer is secreted by the goblet cells in the conjunctiva (mucous lining) of the eyelids and helps the tear film stick to the cornea.

 

 

Main Components

Simplistically, there are three main components of Dry Eye and one individual may have one, two or all three components:

  1. Underproduction – where there is poor production of fluid by the lacrimal glands.
  2. Evaporative – tears evaporate too quickly. Result of poor oil production by eyelid meibomian glands.
  3. Inflammatory – seen in conjunction with dry eye and requires specific treatment.

Laser eye surgery and dry eye

Laser eye surgery, especially traditional Lasik can aggravate dry eye.

Once corrected they can undergo laser vision correction. If they cannot be corrected, Laser eye surgery will not be recommended and other options may be considered.
