Pentacam and Sirius Eye Test in Delhi for Corneal Topography

The Pentacam and Sirius Eye Test at the Save Sight Centre in Delhi are high-tech ways to measure the topography of the eye. These tests give doctors clear pictures of the cornea, which helps them figure out what's wrong with the eyes and treat it. The Pentacam can do a 3D scan, and the Sirius can get accurate readings by combining topography and tomography. These tools are necessary to plan surgeries and make sure that patients get the right care.

What is Pentacam Eye Test?

A moving camera on the Pentacam takes detailed, three-dimensional pictures of the front part of your eye. It is a full eye exam. The eye, anterior chamber, iris, and lens are all studied in this test. It helps doctors figure out what kind of eye disease someone has, like keratoconus, and plan treatments like LASIK by showing them the shape and thickness of the cornea. The pictures and information gathered give a full picture of your eye health, which helps doctors make correct diagnoses and plan your treatment.

What is Sirius Eye Test?

Scheimpflug imaging and Placido disc topography are used to take detailed, 3D photographs of the front of your eye in the Sirius Eye Test. This test accurately measures cornea shape, curvature, and thickness. It helps doctors detect and treat keratoconus, corneal ectasia, and dry eye syndrome. By providing eye anatomy and health data, the Sirius Eye Test helps plan refractive operations like LASIK.

How Sirius Eye Test Help?

Provides precise information on the thickness (pachymetry), elevation, curvature, and power of both the front and back surfaces of the cornea.
Diagnoses the entire front part of the eye in a single step.
Captures high-quality images of the cornea up to 16 millimeters in diameter.
Calculates all necessary measurements for the front part of the eye using up to 100 high-resolution sections. Users can choose how many sections to measure.
Offers more precise centering and results for treatments through static cyclotorsion correction information.

Applications of Pentacam and Sirius Eye Test

Keratoconus Screening These tests provide essential corneal data, helping to detect early signs of keratoconus and prevent complications related to ectasia.
IOL Calculation: Using ray tracing technology, these module accurately calculates intraocular lenses (IOLs) for both treated and untreated eyes, aiding in precise treatment planning.
Intrastromal Rings Placement: : Pachymetry maps and corneal elevation profiles help plan the exact placement of intrastromal rings, improving treatment outcomes.
IOL Alignment and Patient Selection: The Pentacam is used for high-quality and premium IOLs, such as Multifocal and Toric, in cataract surgery to ensure correct alignment and select the right patients.
Pupillography: Sirius measures pupil diameter dynamically or statically under different lighting conditions. Accurate data on pupil center and diameter are crucial for planning and performing refractive treatments.

Video Keratoscopy: Special light sources stimulate fluorescein, aiding in the fitting of rigid contact lenses. This is done with the help of Sirius Machine.
Dry Eye Analyses: A high-resolution color camera evaluates the tear film, meibomian glands, conjunctival and limbal hyperaemia, and tear meniscus size. Thus Sirius provides a comprehensive assessment of the corneal condition and supports the diagnosis of Dry Eye disease.
Corneal Ectasia Detection: Identifies thinning and irregularities in the cornea, helping to diagnose and monitor corneal ectasia.
Refractive Surgery Planning: Supplies crucial data for planning LASIK and other vision correction surgeries, ensuring accurate and safe procedures.
Post-Surgery Monitoring:Evaluates changes in the cornea after surgery to ensure proper healing and outcomes.

FAQs

Que 1: How does the Pentacam help in diagnosing eye conditions?

Ans: It provides precise measurements of corneal thickness, curvature, and elevation, which are essential for diagnosing conditions like keratoconus, corneal ectasia, and glaucoma.

Que 2: Are these tests suitable for everyone?

Ans: Yes, these tests are beneficial for patients of all ages, especially those undergoing refractive surgery, managing eye diseases like glaucoma, or assessing corneal health.

Que 3: Do I need special preparation for a Pentacam or Sirius test?

Ans: No special preparation is required. You may be asked to remove contact lenses before the test to ensure accurate measurements.

Que 4: Are there any risks associated with these tests?

Ans: These tests are generally safe.

Que 5: How long does a Pentacam or Sirius test take?

Ans: The test typically takes a few minutes per eye. It is non-invasive and painless.

Que 6: Can these tests detect early signs of eye diseases?

Ans: Yes, both tests are effective in detecting early signs of conditions like keratoconus, glaucoma, and dry eye syndrome, enabling timely intervention and management.
