GONIOSCOPE THREE MIRROR LENS

A Gonioscope Mirror Lens is a specialized ophthalmic lens used during gonioscopy, a procedure to examine the anterior chamber angle of the eye. This angle is where the iris meets the cornea, and it's crucial for diagnosing conditions like glaucoma. The lens allows eye care professionals to view this angle, which is otherwise obscured by the cornea's curvature.

Key Features of a Gonioscope Mirror Lens:

1. Multiple Mirrors: Gonioscope lenses often have one or more mirrors that allow the examiner to view different parts of the anterior chamber angle.
   • Single-mirror lenses: Offer a direct view of one angle at a time.
   • Three-mirror or Four-mirror lenses: Provide a broader view of the chamber, allowing the examiner to see multiple areas by simply rotating the lens.
2. High-Quality Optics: The lens is made from high-quality glass or plastic to provide a clear, distortion-free image of the angle structures.
3. Contact Lens Design: The lens is placed directly on the eye's surface, typically with a coupling fluid like a saline solution or gel to maintain optical clarity and comfort.
4. Slit Lamp Compatibility: The lens is typically used in conjunction with a slit lamp biomicroscope, allowing the doctor to closely examine the eye under magnification and with controlled lighting.
5. Multiple Views: Depending on the number of mirrors, it allows the professional to rotate the lens for comprehensive viewing of the anterior chamber from different angles.
6. Anti-Reflective Coating: Some lenses are coated to reduce glare and improve the clarity of the image, making the procedure easier and more comfortable for both the examiner and patient.

Common Uses:

• Glaucoma Diagnosis: Gonioscopy is essential for determining whether glaucoma is open-angle or closed-angle, helping guide appropriate treatment.
• Anterior Chamber Angle Evaluation: Helps assess the drainage angle for any abnormalities, blockages, or risks of angle-closure glaucoma.
• Iridocorneal Angle Examination: Useful for evaluating conditions affecting the iris and cornea junction.
