Tracey Wavefront Analysis and Topography
Tracey topography is based on the reflection of concentric rings (Placido disk) from the surface of the cornea, from which a special program calculates its radius of curvature at each point. It is one of the most basic preoperative tests for refractive surgery and the basic diagnostic test for keratoconus. It is also diagnostic for a number of other corneal diseases. The Tracey system also performs wavefront analysis, i.e., it provides a detailed representation of the optical properties of each eye. This system is therefore able to provide us with information on the overall optical function of the eye, as well as the cornea and lens separately, helping in the diagnosis of a number of conditions.
Pentacam Topography-Tomography for Assessment of Anterior, Posterior Curvature, and Corneal Pachymetry Scheimpflug Imaging
Galilei optical tomography provides us with an image of the transverse structure of the cornea, which we use to map its anterior and posterior surfaces and its thickness at each point. This examination complements topography and can help us in the early diagnosis of keratoconus and provide valuable information for the preoperative and postoperative assessment of candidates for refractive surgery. Optical tomography is performed using the most modern dual imaging method with a dual Sheimpflung imaging system.
Visante OCT Optical Coherence Tomography of the Anterior Segment
This examination utilizes Optical Coherence Tomography technology to image the internal structure of the cornea and other details of the anterior segment of the eye. With the help of the detailed anatomical imaging it provides, we can assess corneal conditions such as dystrophies, and make accurate measurements such as the thickness of the cornea after LASIK, locate damage at a microscopic level even when the clarity of the cornea does not allow clinical examination.
Confocal Specular Microscopy of the Cornea
It is a method of imaging microscopic structures of the cornea. Using a special focusing system, it allows us to take microscopic images of the patient’s cornea with a quick and easy examination and to identify lesions that are impossible to detect with conventional examinations.
Medmont-type Computational Perimetry (Visual Fields)
Medmont visual fields are static perimeter tests. They are the basic test for monitoring optic nerve disorders such as glaucoma. They assess the sensitivity of the retina to light at various points. The test requires the patient’s cooperation and takes a few minutes for each eye.
IOL Master Biometry
The IOL Master biometry system measures the dimensions of the eye with great accuracy so that we can calculate the dioptric power of the intraocular lens needed for cataract surgery. It is one of the most advanced systems available. The examination is performed without coming into contact with the patient’s cornea.
