She checks the ICL power when it is delivered to her practice before the patient is even scheduled and again on the day of surgery. It is very easy to mistakenly flip the plus/minus sign on the astigmatism, and the patient could end up with double the amount of astigmatism they start- ed with. The same holds true for LASIK. It is important to verify that the refraction that is programmed into the laser matches the final refraction obtained on surgery day. "As a safeguard, I double check to make sure that the final refraction written in the chart is consistent with a recent refraction that was obtained at a separate preoperative visit. I then confirm once more that the numbers in the machine match continued from page 38 The copy forward button on many EHRs as seen here makes it easy to inadvertently propagate outdated or erroneous information in medical notes.

Indications: ARGOS® is a non-invasive, non-contact biometer based on swept- source optical coherence tomography (SS-OCT). The device is intended to acquire ocular measurements as well as perform calculations to determine the appropriate intraocular lens (IOL) power and type for implantation during intraocular lens placement. Intended Use: The Reference Image functionality is intended for use as a preoperative and postoperative image capture tool. It is intended for use by ophthalmologists, physicians, and other eye-care professionals and may only be used under the supervision of a physician. Warnings and Precautions: • Only properly trained personnel with experience may operate the device and control software and interpret the results. • Factors that influence the measurement of patient's eyes are listed in the User Manual (Table 1): pseudophakic eye, wearing contact lenses, fixation problem, cornea opacity, non-intact cornea, refractive surgery, blood in the vitreous humor, retinal detachment, keratoconus, asteroid hyalosis, ambient light in the room, and deformation of the corneal shape. Please consider the guidance provided in Table 1 when you encounter these factors. • Optical Radiation - This device is equipped with a Class 1 laser light source. ATTENTION: Refer to the ARGOS® User Manual for a complete description of proper use and maintenance, optical and technical specifications, as well as a complete list of warnings and precautions.
