Ophthalmology is the branch of medicine which deals with the anatomy, physiology and diseases of the eye. Since ophthalmologists perform operations on eyes, they are considered to be both surgical and medical specialists.
Ophthalmology includes sub-specialties which deal either with certain diseases or diseases of certain parts of the eye. Some of them are cornea, ocular surface, and external disease, glaucoma, the treatment of retinal problems through non-surgical means.
Dry Eye Syndrome and its Treatment
Punctal plugs increase moisture to dry eyes naturally, and could provide relief of unpleasant symptoms when eye drops are no longer sufficient. By preventing tears from draining away, more moisture remains on the cornea.
Following an examination by your ophthalmologist, the plugs can be placed painlessly, in less than a minute. Relief of your symptoms can be expected within a day or two. In the event that the plugs do not prove to be comfortable, they can be easily removed by being flushed from the tear ducts.
