Eye Examinations

There are various eye examinations conducted depending on the vision issue that needs to be corrected, and the treatment method being used. There is a huge difference between the regular eye exam, examinations conducted before laser-assisted in situ keratomileuses (Lasik) procedure, and the contact lens exam.

There are different treatments used to correct vision, such as eyeglasses or spectacles, Lasik treatment, and contact lenses in Atlanta. For individuals who already have contact lens, the contact lens exam will be to determine if the lenses are a perfect fit for your eyes and if the lenses have any effect on the health of both eyes.

Routine Eye Exam

A routine eye exam is necessary for everyone and not only for individuals who have sight difficulties. A routine eye exam includes the comprehensive examination of the eyes to check for signs that might indicate the patient suffers from chronic health issues like diabetes or hypertension. The health specialists conducting the exam should look out for symptoms that might indicate the presence of glaucoma.

Tests should also be performed to assess the vision sharpness, eye coordination, and pressure of fluid present in the eyes. These tests will help in determining the strength of the prescription required. In addition, health specialists should dilate the eyes to check for any existing eye conditions or underlying chronic health conditions.

Contact lens examination

The contact lens exam is a comprehensive examination conducted on individuals who are already wearing contact lenses and those who want to wear them. There are special tests conducted by optometrists to determine the vision sharpness with and without contact lenses.

The first step is measuring the eye surface to assess the type and size of contact lenses required by that particular patient. After this, the doctor will conduct the tear film examination to determine if the patient has enough tears to allow them to wear the contacts comfortably.

After the tests have been completed, the doctor can now easily provide the patient with a prescription for the contact lenses. The contact lenses vary in type and size, so it is essential for the optometrist to make an accurate diagnosis.

Eye contact lenses are not prescribed as a substitute for glasses as these two perform very different functions. Eyeglasses prescription is measured for lenses that are precisely 12 millimeters from the position of the eyes while contact lenses are measured for lenses that are directly on the eye surface. Improper or inaccurate prescription of contact lenses has the capability to damage the eyes completely.

After an accurate prescription has been made, the next step is deciding on the type of contact lenses you want, extended wear or disposable contacts, colorless, or colored contacts. The optometrist will provide a trial sample which should be worn for several days, mostly about one week after which a follow-up examination is done to determine if your eyes have fully adjusted to wearing the lenses and if they have any effect on the health of the eye.

It is important for both individuals who wear contact lenses and glasses to have a regular check-up at least once annually to check if new vision problems have arisen or the existing problems have worsened.

LASIK or Refractive Surgery

Laser-assisted in situ keratomileuses (Lasik) is an eye treatment method that makes use of a laser to correct vision. This method is often used by ophthalmologists who use a precision laser to conduct eye surgery and insert a lens implant to correct vision problems like myopia, hyperopia, astigmatism, and presbyopia. Lasik’s corrected vision eliminates the use of both spectacles and contact lenses. Prior to having the Lasik treatment, there are various exams conducted, such as topography, pachymetry, keratometry, fundus imaging, and refraction.
