What is ESSential Solution?

• Two leading industry products merge
• ESSential multifocal
• SOLUTION bifocal

3
What is ESSential Solution?

• Translating design with intermediate vision

• Up to 3.50D add in a thinner lens profile

• Decreased lens mass increases patient comfort

• No jump optics

4
What are the Fitting Goals?

• Position slightly below center

• Segment height just below the pupil

• Allow for slight rotation

5
Who are the Best Candidates?

• Mid-life and mature patients who require
  excellent vision at all levels

• Intermediate vision for computer users

• Reading segment for clear near vision

Fitting Example
Spectacle Rx -2.00 - 0.75 x 180 Add 2.00D K
Readings 42.50 _at_ 180 / 43.25 _at_ 090
10
Step 1 Determine Base Curve and Distance
Power
Spectacle Rx -2.00 - 0.75 x 180 Add 2.00D K
Readings 42.50 _at_ 180 / 43.25 _at_ 090
Base curve 7.80mm Distance power - 2.75D
11
Step 2 Determine Near Power
Spectacle Rx -2.00 - 0.75 x 180 Add 2.00D K
Readings 42.50 _at_ 180 / 43.25 _at_ 090

• Determine the patients spectacle Add power and
  add 0.50D

Base curve 7.80mm Distance power - 2.75D Add
2.50D
12
Step 3 Choose Segment Position
Spectacle Rx -2.00 - 0.75 x 180 Add 2.00D K
Readings 42.50 _at_ 180 / 43.25 _at_ 090

• Start at 1.0mm below geometric center
• 1.5mm below geometric center is the only other
  option

Base curve 7.80mm Distance power - 2.75D Add
2.50 Seg position 1.0mm BGC
13
Step 4 Order Lens
Spectacle Rx -2.00 - 0.75 x 180 Add 2.00D K
Readings 42.50 _at_ 180 / 43.25 _at_ 090

• Diameter 9.3mm
• Standard medium prism at 90

Base curve 7.80mm Distance power - 2.75D Add
2.50 Seg position 1.0mm BGC Dia
9.3mm Prism standard _at_ 90

Lens Evaluation

• Alignment along the flat corneal meridian

• Lens translation during down gaze

15
Vision Evaluation

• Allow the lens to settle
• Test the patient's binocular distance and near
  visual acuity
• Over-refract

16
Problem Solving

• Problem Solving Grid
• Lens riding high/low
• Excessive/restrictive movement
• Segment line too low/high
• Excessive rotation
• Poor near/distance vision

17
Problem Solving

• Lens rides high
• Try a steeper base curve
• Lens rides low
• Try a flatter base curve

Seg too high
18
Problem Solving

• Excessive movement
• Try a steeper base curve
• Restricted movement
• Try a flatter base curve

19
Problem Solving

• Seg line too low
• Try a flatter base curve
• Raise segment line
• Seg line too high
• Try a steeper base curve
• Lower segment line

20
Problem Solving

• Poor near vision
• Try a flatter base curve
• Raise segment line

Non-translating

• Poor distance vision
• Over-refract
• Lower segment line
• Change base curve

Translating
21
Problem Solving

• Excessive nasal rotation (gt15 degrees)
• OD use prism axis 110
• OS use prism axis 70
• Excessive temporal rotation (gt15 degrees)
• OD use prism axis 70
• OS use prism axis 110
