Lacrimal surgeries are among the most commonly performed ones in occulopastic surgery. The procedures range from unblocking tear ducts in small children with this very minor congenital dysmorphology to correcting dry eye through surgery. As with many of these procedures, the disorders sound minor but the patients’ lives are seriously affected. Dry eye is more than an inconvenience, sometimes leading to corneal microabrasions, infections, and photosensitivity. Dry eye is caused by any number of systemic autoimmune disorders such as lupus or arthritis, excessive radiation, drug reactions, old age, and lasik and other surgeries. There are other books reviewing lacrimal surgery as a portion of occuloplastic practice. The editors have chosen, in The Lacrimal System: Diagnosis, Management & Surgery, to address the whole range of lacrimal disorders in one concise, practical volume. By broadening the scope of the subject, the editors hope to meet the needs of residents, ophthalmologists who do some lacrimal procedures, fellows who are learning the special procedures, and experts interested in learning about the most recent modifications of technique.
