As technology for corneal topography scanning has improved, more eye care professionals are now incorporating it into their practices. Knowing the value of different corneal topography devices can help eye care professionals select the most suitable one. This choice will enable them to serve their patients more effectively.
Keep reading to learn more about corneal topographers. We will cover how to choose one, the pros and cons of popular models, and tips to get the best value for your money.
Understanding Corneal Topography
Corneal topography is a contactless system that scans the eye to generate a digital image of the cornea. Devices can measure corneal thickness and provide a detailed rendering of the corneal surface. There are three primary types of corneal topography technologies:
The Placido method looks at the front surface of the cornea. It does this by shining a series of black and white rings onto the cornea and capturing their reflection.
Scheimpflug: The Scheimpflug technology uses a rotating camera. It captures the reflection of a slit beam.
This beam sweeps across the cornea. It creates a 3-D image of the front and back elevation. It also measures the thickness of the cornea.
Dual-Scheimpflug Wavefront integration: Dual-Scheimpflug technology utilizes two cameras. [Writer’s note: I was not able to find a good definition of this technology.]
There is a wide range of clinical applications for corneal topography, including:
- Refractive surgery planning
- Contact-lens fitting (keratoconus, scleral lenses)
- Disease screening and progression monitoring
- Post-operative assessment
Key Factors for Selecting a Corneal Topographer
As you consider acquiring a corneal topographer for your practice, think about how you will utilize it. When selecting the right device, consider several key factors.
- Resolution, Repeatability & Maps Generated: Basic clinical functionality is the first factor to consider when selecting a device for a medical office. Select a corneal topography device that provides accurate measurements, detailed maps, and clear images. This will enable you to provide the best possible treatment to your patients.
- Speed & Workflow Integration: Software interoperability is a significant consideration when adding equipment to a practice. Integrating with your current EMR and other software ensures that the new device does not require extra data entry. This helps keep the workflow smooth and reduces the chance of recording errors.
In addition, consider how the device operates and the capture time per patient. A more efficient device can reduce wait times for patients, thereby improving overall patient satisfaction.
- Ease of Use and Training Needs: It is essential that all staff members feel confident and at ease with a corneal topography device. Inquire about training requirements and review the user interface before selecting a device for your practice.
- Data Analyzing & Reporting: Many corneal topography devices can provide automated analysis, which increases efficiency. Another consideration is whether you can create customizable report templates to meet your needs best as you deliver treatment.
- Patient Comfort & Throughput: Patient comfort and convenience are key elements in running an eye care practice. Any screening device should prioritize the patient’s experience.
It should have adjustable height settings and comfortable chin and forehead rests. Instructions from staff should be easy to understand. Comfortable corneal topography machines can improve efficiency for each patient. They help offices move patients through screenings quickly, increasing overall throughput.
- Service, Support & Warranty: Corneal topography devices are sophisticated technological instruments that require ongoing care to operate correctly. Before buying a device, ask the manufacturer and seller about the warranty. Also, check if extra services are included. These services may include on-site calibration, software upgrades, and service contracts.
- Total Cost of Ownership (TCO): Your budget for a corneal topography device should encompass not only the initial purchase price but also ongoing expenses. Consider the operational costs, including consumables, maintenance, and software licensing. The manufacturer or seller can provide an estimate of the yearly cost of owning a corneal topography machine. This helps you understand the total expected costs for the device’s lifetime.
Advantages & Disadvantages of Corneal Topography Systems
Corneal topography systems are valuable diagnostic tools that can be exceptionally useful in planning treatment. However, like any technology upgrade, they can’t replace experienced clinicians and personalized attention to patients. Before purchasing a corneal topography system, consider how it will benefit your patients. Also, consider if the costs are worth the benefits for your practice.
Advantages of Corneal Topography
- Early disease detection: Corneal mapping can help identify diseases like glaucoma at the most treatable stage
- Enhanced surgical planning: Corneal mapping can be a valuable component of planning refractive surgeries, reducing procedure times and improving treatment outcomes.
- Improved lens fitting accuracy: Comprehensive corneal mapping can help clinicians fit specialty contact lenses, such as scleral lenses or lenses to manage keratoconus.
- Objective, quantitative data: Digital imaging provides clear, objective data about the patient’s eyes. Scans are quick and easy to do. They cause no discomfort to patients. This means they can be repeated to confirm initial scans or to track the progress of eye disease.
Disadvantages of Corneal Topography
- Upfront investment: Corneal mapping devices are costly. They require a designated space in the office. Buying a corneal mapping device may need extra money to adjust the office space for the new equipment.
- Training and certification needs: If staff are unfamiliar with corneal mapping, they require training. They must learn to use the device and understand the data. Training may be included as part of the purchase price. However, the time spent learning to use a corneal mapping device takes time away from patient care.
- Ongoing maintenance costs: As with any device, there will be ongoing expenses to keep it operating correctly. You may need to purchase replacement parts and pay for service calls, as well as predictable costs for consumables.
- Potential data integration challenges: If you select a corneal topography device that doesn’t integrate with your existing office systems, you may increase your staff’s workload. Consider whether the device can send data to EMR systems independently. Or will staff need to add scans to each patient file manually?

Putting It All Together: Making Your Decision
As you evaluate the features of various corneal topography devices, consider how they align with your practice’s specific needs. You should avoid buying a device with features you won’t use often. However, it is also essential to select a machine that offers all the necessary functions. Integration with current systems is also a key feature to look for, since connectivity between systems streamlines workflows.
Compare cost estimates for different options. A lease with a strong service contract may be a better option than buying a device outright. This is especially true if you plan to grow your practice in the next few years.
The option to upgrade at the end of a lease term may be a financially sound decision. If you decide to buy, consider asking about potential future upgrades. This way, your corneal topography device can grow with your practice and adapt as technology improves.
Some stores allow you to try a device before making a purchase. This can help you feel more sure about your choice.
Additionally, inquire about installation, training, and service plans. You may be able to negotiate a package for training and support as part of your contract to purchase a device.
Ask about discounted rates on replacement parts and consumables for the device as part of your service contract. Ensure the service package is compatible with the manufacturer’s warranty. This way, you will have full coverage.
