Course Content:

The modern ophthalmology office is moving toward push-button efficiency. Push a button and you have an "IOL measuremnt". Push another button and you have an "IOL power calculation". Often, this is all you need to do, but not always. Cataract surgery is becoming more and more complex, and the public is demanding higher levels of perfection. This course is designed to give the ophthalmic technician the tools and understanding to be able to insure and confirm accurancy of measurements and calculations before surgery, and to evaluate the (hopefully) rare post-op surprise.

The following topics are discussed in Part 1:

1. Types of IOLs
2. Basics of A's and K's
      The basic power calculation: what it tells us and how to use it
      The "average" eye
      Rounding up
3. How the following relate to the IOL power:
      nearsightedness
      farsightedness
      flat and step corneas
      short and long eyes
4. Corneal Measurements
      Options for K readings
      Reproducibility
      Standard deviation
      The corneal surface
      Fixation and head position
5. Axial length measurements
      Options for axial length measurements
      Confirmation of measurements
6. IOL calculation formulas
      Modifications to the formula
           the IOL power/refractive error relationship
           monovision
           the surgeon factor
7. The contact lens wearer
8. The refractive surgery patient
9. Macular OCT

The following topics are discussed in Part 2:

1. Limbal relaxing incisions (LRI) and Surgically Induced Astigmatism
      Parameters
      Calculations via a website
2. Toric IOL calulations
      Parameters
      Calculations via a website
3. Using a topographer in the IOL evaluatiion process
      Types of topographers
      Evaluating abnormal corneal shape
      Multi-focal IOLs and contrast
      Evaluating higher order aberrations
      Evaluating spherical aberrations
      Evaluating corneal astigmatism
4. Special situations
      Silicone oil
      Posterior staphyloma
      Scleral buckle
      Calculations for the highly myopic eye
      Lens position and lens power
          anterior chamber
          in-the-bag
