Here are additional pre-surgical case examples to review: - Patient 1: Keratoconus in both eyes, worse in right. Best corrected vision 20/60 in right, 20/40 in left. Steep cornea with thinning. Consider Intacs to flatten cornea and improve vision. - Patient 2: Asymmetric keratoconus. Left eye moderate, right eye advanced. Right eye best corrected 20/100. Consider Intacs in right eye to improve vision and stabilize further ectasia. - Patient 3: Keratoconus diagnosed 5 years ago. Wears rigid gas permeable lenses but vision fluctuates. Best corrected 20/40. Consider Intacs to improve and stabilize vision long term

1. What Do Intacs Do?
Reshapes The Cornea From Within
Restoring Symmetry To An Asymmetric Cornea

2. Background
Addition Technology in collaboration with highly
experienced Intacs surgeons have analyzed
thousands of cases over a multi-year period to
provide a “best practices” approach to pre-surgical
planning and case review.
Since keratoconus is unique to each case and is a
perfectly imperfect condition, an in-depth
understanding of the optical principals, physics &
clinical application can be provided on one-on-one
case analysis of your cases.

3. What Do We Know?
The Medical Community Has Shown Us …
• Intacs corneal implants flatten the cornea helping achieve a functional contact
lens fit.
• Intacs corneal implants help provide patients the best functional corrected
visual acuity and contact lens fit.
• Intacs corneal implants stabilize the cornea helping the patient defer the need
for a corneal transplant.
• According to a survey of 76 U.S. surgeons who performed 2,136
Intacs surgeries, only 1.9% have gone on to a corneal transplant. 3
3 Based on a patient survey of 76 U.S. refractive ophthalmic surgeons who performed 2,136 Intacs surgeries between August 2004 and April 2008
