Slit lamp accessories enhance the functionality, precision, and diagnostic capability of ophthalmic slit lamps. These accessories are essential in ophthalmology clinics, hospitals, optometry practices, and teaching institutions for detailed eye examinations and imaging.

Key Slit Lamp Accessories

1. Tonometer (Applanation Tonometer)

Used to measure intraocular pressure (IOP) for glaucoma screening.

• Compatible types: R-type, Z-type, GAT tonometers

• Mounts directly onto the slit lamp.

2. Diffuser / Diffuse Illumination Filter

Softens the slit beam for overall inspection of the eye surface.

3. Cobalt Blue Filter

Essential for fluorescein staining tests—detects corneal abrasions, ulcers, and tear breakup.

4. Yellow Barrier Filter

Enhances fluorescein contrast for contact lens fitting and dry eye evaluation.

5. Patient Chin Rest Papers

Disposable papers that maintain hygiene and prevent infection transmission.

6. Replacement Bulbs / LED Modules

Halogen or LED lamps used to maintain optimal illumination.

7. Camera Adapters / Digital Imaging Modules

• Allows photo and video capture

• Connects to computers for documentation and telemedicine

• Styles: Beam splitter, C-mount camera, smartphone adapters

8. Breath Shield (Protective Shield)

Transparent shield protecting clinician and patient from droplets (especially post-COVID).

9. Power Supply / Control Unit

Replacement or upgraded power modules for illumination stability.

10. Chin Rest & Forehead Rest Pads

Soft, replaceable pads to improve patient comfort.

11. Slit Lamp Calibration Tools

Used for optical alignment, focus accuracy, and mechanical calibration.

12. Examination Lenses (Auxiliary Lenses)

High-resolution lenses used with the slit lamp to view different parts of the eye:

• 90D Lens – retina and optic disc

• 78D Lens – macular detail

• 60D Lens – high magnification retina

• Three-Mirror Lens – angle, retina periphery, and posterior pole

• Gonioscopy Lenses – 4-mirror or Goldmann 3-mirror for angle assessment

• Fundus Lenses – for posterior segment imaging

13. Dust Cover

Protects slit lamp optics and mechanics when not in use.

14. Joystick / Mechanical Spare Parts

Replacement parts including:

• Joysticks

• Chin rest rods

• Headrest assemblies

• Slit width/height control knobs

15. Table Mounts & Motorized Tables

Optional:

• Manual table

• Motorized ophthalmic table

  Improves ergonomics for patient access.

16. Disinfectant-Safe Eye Shields & Accessories

For maintaining hygiene between patient examinations.

Summary

Slit lamp accessories improve:

• Diagnostic accuracy

• Functionality

• Patient comfort

• Documentation (digital imaging)

• Safety & hygiene
