Information You Can Provide to the Laboratory Consultant

What information should I provide?

“I always emphasize corneal topography — if available — as the primary resource to provide us. In addition, any parameter information on trial lenses that have been fit on this patient as well as the over-refraction should allow us to provide you with a lens that you can dispense and should meet — or come close to meeting — the patient’s expectations.” (Keith Parker, Advanced Vision Technologies)

“If possible, any lens-on-eye photographs or images that can be emailed would be valuable. Better yet, as it is relatively easy to take video images from an iPhone, this would be very helpful.” (Richard Dorer, Blanchard Contact Lens)

“The more information we have on the patient and their history, the better. The patient’s newest K reading and refraction, along with previous lenses worn and any maps, are very helpful. The patient’s best visual acuity and expectations are also helpful information to have.” (Kelsey Roberts, Valley Contax)

“Ks, spectacle Rx, corneal diameter, pupil size, and topography, if available, are all important to provide. Also, be sure to indicate if this is a previous or current lens wearer, and include information on lens specifications, evaluation of fit, and over-refraction.” (Joe Hanson, Mid-South Premier Ophthalmics)

How valuable are corneal topography images?

“If you have a topographer in your office, then it is very worthwhile to capture topography on all contact lens patients. You may observe many normal-appearing corneas, but you may also see any irregularity that may not be observed with keratometry. It is also essential for understanding the irregularity that is detectable with keratometry. Please send us your files, as we can work with most every topography system.” (Mike Johnson, Art Optical)

“Extremely. So much so, that we have invested in getting the software to open images from the more popular brands of topographers so you don’t need to convert the images or scan them to send to us.” (Susan Faul, Paragon Vision Sciences)

“Corneal topographies are very helpful, especially for patients with irregular corneas. I always request maps if they are available.” (Kelsey Roberts, Valley Contax)
