What is keratometry?
keratometry is a process used to measure corneal curvature. An eye specialist, such as an ophthalmologist, is performed using a device known as a keratometer or ophthalmometer. No special preparation for keratometric session is required for the patient's parts, and the procedure is usually painless if the patient does not try to sit down. The basic keratometer was developed in 1880, although the proposal has been significantly refined since then. Most modern keratometers use computers and optical sensors, rather than forcing a doctor to make calculations, and the computer can compare the cornea of the patient with a database of known measurements and typical standards. Finally, the numbers will be created so that keratometry data can be recorded in the patient's graph or passed to other doctors.
One of the main reasons for keratometry is to control the patient's astigmatism, the problem of vision caused by inconsistencies in the shape and curvature of the cornea, and determining the degree of astigmatism. With numbers from keratometer, the doctor can determine which optionsThey are available to repair astigmatism so that the patient can see more clearly. The device can also be used to search for corneal -shaped discrepancies between the eyes.
Before certain types of eye surgery, the surgeon can ask keratometry to get a complete picture of the eye, and the measurement can also be used to guide the procedure. After eye surgery, it is also common for a keratometer to be seated, so the results of surgery can be followed and the eye can be monitored for changes. Identification of unexpected changes in the eye is critical because this may mean that the occasion is quickly seen.
As with correction lens recipes, patients can take keratometry values if they want care from another doctor. Patients can also apply for copies of their graphs, something patients may want to do if they have complex eye problems and move to another area. Having a copy of the chart can save a new time of a doctoreye and ensure that the patient receives the most suitable care and treatment from the first vision.
