  4. What Every Tech Should Know About Contacts Basic understanding of types of CL and reasons to go with one modality or another. • How to insert and remove CL and how to instruct patient to do so. • Appropriate cleaning material and procedure for each modality • How to evaluate VA and perform an over-refraction. • Basic understanding of evaluation of fit.

  5. Basic understanding of types of CL and reasons to go with one modality or another.

  6. Types of Contacts Soft Contact Lenses - Sphere only, toric, multifocal - variety of replacement schedules: daily, weekly, 2 week, monthly, 3 month, annual - comfortable with variety of lens materials and colors - wide price range to suit most budgets - relatively easy to insert/remove and care for. RGPs – Sphere, toric, multifocal - can last years with careful maintenance - relatively inexpensive - relatively easy to insert/remove and care for - superior optics to soft contacts Hybrids - optics of RGP with comfort of a soft contact Scleral Lenses - comfortable with good optics

Types of Contacts Soft Contact Lenses - Sphere only, toric, multifocal - variety of replacement schedules: daily, weekly, 2 week, monthly, 3 month, annual - comfortable with variety of lens materials and colors - wide price range to suit most budgets - relatively easy to insert/remove and care for. I CAN’T SEE ANYTHING RGPs – Sphere, toric, multifocal - can last years with careful maintenance - relatively inexpensive - relatively easy to insert/remove and care for OW? ARE YOU KIDDING ME?! Hybrids - optics of RGP with comfort of a soft contact YOU WANT ME TO DO WHAT?! Scleral Lenses - comfortable with good optics CHA CHING$$$

  8. Explain the options.Know the Pros and Cons.Let the patient &/or doctor decide.

  9. Insertion and Removal

  10. Caring for the contacts

  11. Achieving the best acuity

  12. YOU HAVE TO KNOW THE PATIENT’S BEST CORRECTED VISUAL ACUITY OR EXPECTED VISUAL POTENTIAL!

  13. Over-Refraction Soft Contacts – can use trial frames, push plus All others – use fogging with phoropter Start with just sphere only, however, if that doesn’t reach BCVA then check Cyl/Axis

  14. Fitting Soft Contact Lens - General Recommendations: Movement: They should move .5-1mm. Comfort counts more than the rule! Generally, as long as movement isn’t past limbus, or if tight that they are free to push, then it’s ok. Excessive movement = flat fit = decrease base curve (steepen) or increase diameter Little to no movement = steep fit= increase base curve (flatten) or decrease diameter Alignment: Let comfort be your guide! Decentered is okay as long as limbus is covered.

Decentered is okay as long as limbus is covered. Rotation: Observe where the toric mark lines up.
