Dry eye

Dry eye commonly causes discomfort, poor vision and damage to the front parts of the eye. It is normally caused by not enough fluid being produced in the eye or too much evaporation because the oil glands within the eyelids are not working properly. Many other eye problems have similar symptoms and a careful examination is needed for a correct diagnosis.


Dry eye clinic

Dr Michael Johnson runs a medical clinic for dry eye and ocular surface problems. These conditions can be dealt with during regular eye examinations when they are mild, but more advanced cases benefit from a separate consultation. This allows for specialist tests to fully investigate the causes of any problem, and so advise on treatment.

A dry eye assessment is tailored to the specific needs of the patient, but usually involves a careful examination of the front surface of the eye and eyelids. The production, drainage, volume and stability of the tear film are measured. Images of the front of the eye may be taken to better explain problems and allow monitoring.

Treatment may involve lubricants, antibiotics, steroids and lifestyle/dietary advice. Some patients do best when small, hypoallergenic silicone plugs are used to prevent the outflow of tears through the drainage holes in the eyelids. This retains natural tears, and allows the ocular surface to benefit from their lubricating and nourishing actions.

Severe dry eye is often associated with a health condition affecting the whole body, and so we have networks to co-manage with GPs, rheumatology and dermatology.


Our credentials for managing dry eye

Dr Michael Johnson obtained his PhD on dry eye, which led to the advancement of several clinical tests and the development of a method of measuring treatment effects that has been approved for use in large clinical trials. He has published numerous scientific papers and acts as a reviewer for academic journals on the subject. Before setting up his own practice he worked as a consultant to global pharmaceutical companies, including Pfizer, Allergan and Chemedica. He is regularly invited to present at conferences on the subject.
