Slit Lamp Digital Imaging Systems

Frequently Asked Questions about the EyeRes™ Slit-Lamp Imaging System

Before contacting us, please browse our FAQ.

What imaging systems do forward-looking doctors such as Dr. Paul Karpecki, Dr. Ben Gaddie, and Dr. Mile Brujic use in their practices?

More and more ODs are turning to TelScreen EyeRes slit lamp and slit lamp imaging systems. Doctors Paul Karpecki, Ben Gaddie, and Mile Brujic, for example, are amongst the many ODs who have purchased and are presently using TelScreen products in their eye care practices.

What financial benefits can my practice expect?

National statistics indicate that about 30% of your patients have conditions that should be treated, followed and photographed. It is not unusual for practices to have $2,000 to $4,000 per month in slit-lamp imaging revenue. Some have less, some have more. On a 60-month finance agreement, you have nearly 8x coverage of the monthly payment at the low end of the revenue range. So, you can take a week or two of vacation without worrying about having enough imaging revenue for the equipment to pay for itself.

What eye care benefits can my patients expect?

Videos and images help patients to understand more, and to understand more quickly. The system is also useful for contact lens fitting (send pictures to the lab for consultation) and for encouraging lens care & replacement compliance – “If you aren’t replacing your lenses on schedule, this picture will show it.” Any patient with a medical condition (keratitis, conjunctivitis, dry eye, etc) will benefit from a visual explanation, and will be more likely to comply with your treatment plan.

Can I take a photo of the optic disk with the EyeRes system?

If you can see it through the slit lamp oculars, you can photograph it. For posterior photos at the slit lamp, a dilated pupil is extremely helpful, and a condensing lens is required. We recommend the Volk / TSi 1.0 Digital Imaging Lens.

I like the idea of eye photography—but will it slow me down?

Dr. Larry Alexander helped us refine the user interface until he was taking slightly less time per patient with slit lamp imaging than he was without it. When implemented correctly in a practice, the EyeRes system will not slow you down.

When I take a photo of the optic disk or macula with the EyeRes system on my slit lamp, is that a slit lamp photo or a fundus photo? How do I bill for it?

The procedures are defined by “what did you photograph” not by “which instrument did you use to photograph it.” So, optic disk and macula photos are fundus photographs, regardless of how you acquired the image. You should bill for CPT 92250 Fundus Photography.

What determines if my photography procedures are “covered for reimbursement”?

Coverage is dependent upon the pathology, the state, and the patient’s medical coverage. Medicare coverage in a particular state either follows the national coverage (559 ICD-9 codes) or is limited by a Local Coverage Determination. Go to and select your state. Then look for an Ocular Photography LCD. Or, just call TelScreen and we’ll send you the information. Private insurance usually covers the same or more conditions, and usually reimburses the same amount or more than Medicare.

I don’t bill medical insurance. Is there any reason for me to have a slit-lamp imaging system?

Yes. Some doctors use it solely for practice marketing. Every patient sees a photo, and anyone who is with the patient (e.g., parent, spouse, caregiver, adult child, etc.) gets a much more complete understanding of the expertise you deliver. Some doctors differentiate their practices by the quality of their patient education.
