1. Settings (gear icon) - Usually found in the top-right or bottom-left corner of the chat window
2. Appearance / Theme settings - Look for options labeled "Appearance", "Theme", "Display", or "Customize"
3. Profile settings - Some platforms put color/theme options under your user profile

• Check the admin panel or widget settings where the chat was configured
• The chat widget color is often set by whoever deployed it, under branding/customization options

• Look for a Branding or Widget Customization section in the Orris dashboard
• Chat bubble color, header color, and accent colors are typically configurable there

• Are you a user trying to change how the chat looks for yourself?
• Or are you an admin/developer setting up the chat widget for a website?

1. Contact your Orris administrator - If this is a deployed instance, the admin can update the widget's CSS/theme settings.
2. If you have admin access - Look in the Orris dashboard under Appearance, Branding, or Theme settings for a color picker for the input field.
3. If it's a custom deployment - The chat input background color would be in the CSS, something like:

   .chat-input {
     background-color: #000000; /* black */
     color: #ffffff; /* white text so it's visible */
   }
   

4. Browser workaround (for yourself only) - You can use a browser extension like Stylus or User CSS to override the styling locally on your end.

.chat-input {
  background-color: #000000;
  color: #ffffff;
}

1. Install Stylus for Chrome/Firefox
2. Create a new style for the Orris URL
3. Paste the CSS above and save

<textarea class="chat-input" style="background-color: #000000; color: #ffffff;"></textarea>

.chat-widget .input-area textarea {
  background-color: #000000;
  color: #ffffff;
}

POWER % Column - Marked Area Explained

UNOCCLUDED

45

LINEAR

• In LINEAR mode, power is proportional to how far down you press the foot pedal
• Pressing the pedal halfway gives roughly half the max power (22.5%), full depression gives 45%
• This gives fine intraoperative control vs. PANEL mode (which gives a fixed preset power the moment you enter position 3)

CONTINUOUS

• Continuous = uninterrupted, constant ultrasound energy delivery when pedal is in position 3
• The alternative modes are Pulse (on/off cycling) or Burst (bursts at set intervals)
• Continuous delivers the most energy per unit time - useful for hard nuclei during sculpting

⭐ 10 / 4 (71%) - WhiteStar Technology

• Even though the mode says "Continuous," WhiteStar micro-pulses the energy at a very fast rate (within that continuous delivery)
• The 4 ms OFF period allows thermal dissipation at the corneal incision, dramatically reducing the risk of wound burns
• Fluid is also drawn back during the OFF phase, helping with holdability of the nucleus fragment
• Net effect: less thermal energy to the eye while maintaining cutting efficiency

Quick Clinical Summary

The Apparent Contradiction - Resolved

What Siebel's book says (and it's correct)

• Use continuous power because you need sustained ultrasound energy to mechanically cut through hard nucleus
• Pulse or burst modes can cause the tip to "stall" in the groove because energy is intermittently absent
• Holdability (the ability to keep the nucleus engaged on the tip) depends on sustained energy during cutting

The Key Distinction: Two Separate Levels of "Continuous"

Surgeon presses pedal for 3 seconds:
|████████████████████████████████████████| ← Siebel's "CONTINUOUS" (3 seconds of active phaco)

What WhiteStar is doing inside those 3 seconds:
|██████░░░░██████░░░░██████░░░░██████░░░░| ← 10ms ON / 4ms OFF cycling
    (71% duty cycle, 100s of cycles per second)

Why WhiteStar Does This (The Thermal Problem)

• Thermal wound burns (wound necrosis)
• Wound distortion affecting final refractive outcome
• Corneal edema

1. Heat dissipation at the wound
2. Fluid ingress around the tip (cooling)
3. Cavitation bubble collapse - actually improving cutting efficiency

The Bottom Line

Sovereign Compact - Soft Cataract Sculpt/Trenching Settings

Core Principle for Soft Nucleus

"Let the fluidics do the work, not the ultrasound." A soft nucleus aspirates easily - excessive power will cause the nucleus to chatter, move away, or worse, rupture the posterior capsule.

Recommended Parameter Changes

1. POWER % Column (the marked area)

• Soft nucleus does not need mechanical cutting - aspiration alone does the job
• High power on a soft lens causes nucleus repulsion (the nucleus bounces away from the tip due to cavitation)
• Excess power = unnecessary heat and endothelial damage
• The Sovereign cuts efficiently at as low as 5% for soft/average nuclei (Dr. David Chang's published experience)

2. ASP RATE (Aspiration Flow Rate) Column

• Low aspiration prevents accidentally aspirating the soft nucleus whole while you're trying to groove it
• Prevents dragging the posterior capsule forward prematurely
• 15-20 cc/min is the safe range for sculpting any nucleus density

3. MAX VAC (Vacuum) Column

• Low vacuum = low risk of occlusion at the tip during grooving
• Occlusion during sculpting near the equator can tear the zonules or posterior capsule
• Save high vacuum (200-400 mmHg) for quadrant removal AFTER trenching is complete

Suggested Complete Setting Profile for Soft Cataract Sculpt

MODE:        SCULPT
POWER:       15% max | LINEAR | PULSE (or Continuous at 15%)
             WhiteStar: 6ms ON / 8ms OFF (lower duty cycle ~43%)
ASP RATE:    15-18 cc/min | PANEL
VACUUM:      40-50 mmHg | LINEAR

Practical Tips for Soft Cataract on Sovereign Compact

1. Consider "0% power sculpting" - Many experienced surgeons trench a soft nucleus in foot pedal position 2 only (pure aspiration/vacuum, zero ultrasound). The soft nucleus aspirates into the groove without any phaco energy at all.
2. Pulse mode over Continuous - If you do use power, switch from Continuous to Pulse via the SUBMODE button on the right panel. Short pulses give you better tip control and less nucleus repulsion.
3. After trenching - increase vacuum significantly for quadrant removal: go up to 250-350 mmHg once you switch to quadrant removal mode.
4. Watch your chamber - Soft cataracts have weaker zonules more often. Keep bottle height standard (not too high) to avoid excessive pressure.
5. The Sculpt → Quadrant removal transition: Once trenching is complete, hit PHACO SETTINGS on the right menu to switch to your quadrant removal parameters before chopping.
