Scleral lenses have become a cornerstone of modern optometric care, particularly for patients with complex anterior segment disease. Conditions that once resulted in limited visual potential—such as keratoconus and post–corneal transplant irregularity can now be managed with greater precision, comfort, and long-term stability.

In Grand Rounds LIVE: Getting It Right With Scleral Lenses, hosted by Dr. Chris Lievens, clinicians explored how advances in scleral lens design and anterior segment imaging are changing clinical decision-making. Expert insights were provided by Dr. Brooke Messer, along with a real-world case presentation by optometry student Sarah Sumida. Central to the discussion was the role of advanced imaging—specifically the Heidelberg Engineering Anterion in elevating scleral lens evaluation beyond visual acuity alone.

Historically, scleral lens success was largely defined by best-corrected visual acuity and central vault. While these factors remain important, they no longer tell the full story—particularly in post-surgical or irregular corneas.

Modern scleral lens evaluation requires clinicians to assess:

These factors are often invisible without wide-field anterior segment imaging, underscoring why technology has become inseparable from contemporary scleral lens care.

To illustrate these principles, the session focused on a patient case that reflects many real-world challenges encountered in specialty contact lens practice.

Importantly, the patient reported overall satisfaction with her scleral lenses and had worn the same lens design successfully for several years.

Slit lamp examination revealed stable findings in the right eye with mild neovascularization. The left eye, however, demonstrated central and paracentral corneal haze with associated edema. Notably, the scleral lens fit itself appeared appropriate, with no significant blanching or landing issues.

At this point, the case highlighted a critical clinical pivot: despite stable lens performance, something was changing at the corneal level.

Further history uncovered the key contributor—the patient had stopped using her prescribed maintenance steroid, despite a known history of graft rejection. This discovery shifted the clinical focus away from lens design and toward corneal health and long-term management.

This is where advanced imaging became essential. The Heidelberg Engineering Anterion provides wide-field anterior segment OCT imaging, allowing clinicians to visualize up to 16.5 mm across the anterior segment. This capability enables a comprehensive assessment of:

In post-PKP eyes, a lens may appear ideal centrally while exerting subtle stress in the mid-periphery. Without wide-field imaging, these issues can go undetected until corneal health begins to decline.

One of the strongest clinical takeaways from the discussion was the importance of imaging asymptomatic patients. Establishing baseline anterior segment OCT data allows clinicians to:

Rather than waiting for visual decline, proactive imaging supports earlier, more confident intervention—often preserving both corneal health and lens success.

Once imaging confirmed that the scleral lens was not the primary issue, attention turned to medication adherence. Similar to glaucoma management, graft rejection can progress silently until vision is compromised.

The panel emphasized that re-education must be ongoing, particularly as follow-up intervals extend. Patients may interpret clinical stability as permission to discontinue therapy, making it essential to reinforce:

In this case, restoring compliance was far more impactful than altering lens parameters.

When a scleral lens has performed well over time, the recommended approach is conservative:

Clinical stability and corneal health, not the pursuit of a “perfect” image, should guide lens replacement decisions.

This Grand Rounds LIVE case reinforces that modern scleral lens care extends well beyond achieving good visual acuity. By integrating patient education, thoughtful lens management, and advanced imaging with tools such as the Heidelberg Engineering Anterion, eye care professionals can better protect corneal health, extend graft longevity, and improve long-term outcomes for complex patients.

Ultimately, the most meaningful clinical decisions often come not from changing the lens—but from understanding the eye beneath it.
