DESIGN AND IMPLEMENTATION OF A COMPUTERIZED OPHTHALMOLOGIST INFORMATION SYSTEM CASE STUDY OF NIGER MEDICAL OPTICS, ENUGU

ABSTRACT

Ophthalmology information system is concerned with the function and care of the eye and with the disorders that affect it. An ophthalmologist is a physician who has graduated from medical school and completed at least three additional years of special training in the diagnosis and treatment of eye disorders. Ophthalmologists are qualified to perform medical eye examinations, prescribe corrective eyeglasses and contact lenses, treat diseases of the eye, and perform eye surgery. Some ophthalmologists specialize in treating particular parts of the eye, such as the cornea (the transparent cap at the front of the eye) or the retina (the light-sensitive membrane lining the back of the eye). Others specialize in working with specific patient populations. Ophthalmology information system is to document information concerning eye problems. This project is written to help hospitals especially Niger Medical optics Enugu in the areas they encounter problems in keeping their record and the solution given to tackle those problem. The research was carried out of many difficulties such as time factors, money and inability to get much information that could have been of help. But still with all those the researcher came up with something readable and valuable to any body that goes through it. This project is implemented with the help of visual basic programming language and Microsoft access. The Microsoft Access is used for the database creation.
