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)

“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, ABB Optical Group)

“Slit lamp and OCT images with trial lenses on the eye really help the consultants in determining the changes needed. Lens marking orientation is very critical in determining areas of the lens in need of modification.” (Eric Marshall, Visionary Optics)

“In consultation, the more information provided, the better the lens fit outcome. The most recent K readings, refraction, and patient condition are the very least needed. Along with that, topography, trial lens fluorescein images, patient history, and patient expectations are all helpful for a successful fit.” (Derrell James, X-Cel)

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. Send us your topographies. We understand and can work with information from nearly every brand of topographer.” (Mike Johnson, Art Optical)

“Corneal topography is quite useful in fitting custom lenses. We ask that an axial map as well as an elevation map for both eyes be sent to us. Receiving this information online aids the consultant in determining which design may be best for the patient. With the recent concerns about trial lens disinfection, first lens selection programs based on topography will become much more the norm.” (Keith Parker, Advanced Vision Technologies)

“Good communication between the practitioner and the consultant is crucial when designing and fitting a GP lens. As they say, ‘a picture is worth a thousand words.’ So a topography is a very useful tool for accurately and quickly conveying the essential information necessary to design the lens.” (John Belliveau, Visionary Contact Lens)

“In addition to topography, OCT images are invaluable in both the initial fitting, follow-up, and troubleshooting of scleral lenses.” (Bernie Ferguson, SynergEyes)
