Pentacam examination is an examination method used for detailed imaging and analysis of the front part of the eye. This examination is very important, especially to measure the topography and thickness of the cornea. Pentakam is a device that works similar to optical coherence tomography (OCT) of the eye and provides high-resolution images.
Purposes and use of Pentakam examination:
1. Topography of the cornea:
It measures and maps the curvature and shape of the corneal surface. This information is used to diagnose and monitor keratoconus, astigmatism, and other corneal abnormalities.
2. Corneal thickness (pachymetry):
The thickness of the cornea is measured at different points. This is important for the diagnosis of keratoconus and other ectatic diseases. It also helps in accurate measurement of intraocular pressure.
3. Front camera depth and angle analysis:
It is used to diagnose and monitor glaucoma by measuring the depth of the anterior chamber (the space between the cornea and the iris) and the angle between the cornea and the iris.
4. Eligibility for laser refractive surgery:
It is used to evaluate the suitability of the eye for laser refractive surgery procedures such as LASIK and PRK. Corneal thickness and topography are critical for these operations.
5. Planning for Cataract Surgery:
It can be used to determine the power and type of intraocular lens (IOL) to be used during cataract surgery.
The course of the Pentakam examination:
Preparation:
The examination does not require special preparation. However, contact lens wearers should remove the lenses a few days before the examination to allow the cornea to return to its natural state.
Examination:
You sit in front of the device and place your head and chin on a special support.
Keeping your eyes open and steady, you look at the light source inside the device.
The device performs various measurements by scanning the front part of the eye. This process takes a few minutes and does not cause any discomfort.
Analysis:
The collected data is analyzed by the device and a detailed map of the eye is produced.
The doctor evaluates this information, obtains detailed information about the health of the eye and makes recommendations on the necessary treatment or additional examinations.
Advantages of Pentakam examination:
High precision: Enables precise imaging and measurement of the anterior part of the eye at the micrometer level.
Non-invasive: During the examination, the eye is not touched and any discomfort is not felt.
Early diagnosis: Helps detect corneal and anterior chamber abnormalities at an early stage.
Treatment planning: Helps to develop an appropriate treatment plan for refractive and cataract surgery.
Pentakam examination is a very important tool for the protection and treatment of eye health. Applying this procedure as part of regular eye examinations helps to prevent serious eye diseases and to develop effective treatment plans.
