Refractive errors of the eye
Refractive errors of the eye:
Refractive operations are performed to correct refractive errors in the eye, which include LASIK and PRK.
To perform these operations, it is necessary to check the complete characteristics of the cornea before the operation. Devices for specialized corneal examination are:
Determine the thickness of the cornea
Pachy metry through Pentacam sound waves, Orbscan through laser
Topography examines the surface map of the cornea
Orbscan, which outlines the anterior and posterior surface and the thickness of the cornea
Gallile, Pentacam Newer devices that give your doctor more complete specifications of all corneal levels.
Zywave device, OPDscan
LASIK is performed in two simple and advanced methods. In the new advanced method to correct all the very delicate unevenness of the corneal surface of these devices, all the corneal characteristics of each person are photographed separately and statistical information is calculated and sent directly to the laser device in the room. It is sent that the laser device acts directly on the basis of this information, which is called Customized Ablation. In some people who are able to perform LASIK or PRK due to corneal problems or the patient’s cornea is out of proportion to the eye number. Use an intraocular lens change without cataract surgery to get rid of the glasses.
