Rapid Relief for Dry Eye: Could Cequa Revolutionize Cataract Surgery Prep?
For decades, ophthalmologists have understood that a healthy ocular surface is paramount for accurate biometry and optimal outcomes in cataract surgery. But what if achieving that healthy surface could be dramatically accelerated? New research suggests cyclosporine 0.09%, specifically delivered via Cequa, may offer just that – significant improvements in dry eye signs and symptoms within just 7 days, potentially reshaping pre-operative protocols.
The Speed of Recovery: A Game Changer for Refractive Cataract Surgery
Traditionally, cyclosporine treatments for dry eye have been a long game, requiring weeks or even months to demonstrate noticeable effects. This presented a challenge for patients scheduled for cataract surgery, where a compromised ocular surface could lead to inaccurate measurements and compromised visual results. The study, presented at the American Society of Cataract and Refractive Surgery meeting, challenges this paradigm. Researchers, led by John A. Hovanesian, MD, FACS, found statistically significant reductions in higher-order aberrations (HOAs) – distortions in vision often exacerbated by dry eye – as early as one week after initiating Cequa treatment.
Study Details and Key Findings
The multicenter study involved 46 patients with moderate to severe dry eye, defined by corneal fluorescein staining and a tear breakup time (TBUT) of 10 seconds or less. All patients received Cequa in one eye, and researchers tracked changes in HOAs, corneal staining, TBUT, and patient-reported symptoms using the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire. The results were compelling:
- Significant improvements in HOAs were observed at both 7 and 28 days (P < .005 and P < .0001, respectively).
- 57% of patients showed improvement in HOAs by day 7 (P < .004), rising to 59% by day 28 (P < .03).
- Corneal staining was eliminated in 28% of patients after just 7 days, increasing to 61% by day 28 (P < .0001).
- TBUT improved significantly at all time points (7, 14, and 28 days; P < .0003, P < .0001, and P < .0001, respectively).
- SPEED scores also showed statistically significant improvements as early as day 7.
Importantly, the positive effects of Cequa were consistent regardless of whether patients also used artificial tears, suggesting a distinct mechanism of action beyond simple lubrication.
Beyond Preparation: Expanding the Role of Rapid-Acting Cyclosporine
While the study focused on pre-operative optimization, the implications extend beyond cataract surgery preparation. The rapid onset of action suggests Cequa could be a valuable tool for managing acute flares of dry eye, providing quicker relief for patients experiencing significant discomfort. This is particularly relevant given the increasing prevalence of dry eye disease, often linked to prolonged screen time and environmental factors. The American Eye Epidemiology Study Group estimates that over 48 million Americans suffer from dry eye, a number projected to rise in the coming years.

The Future of Ocular Surface Disease Management
The findings raise intriguing questions about the potential for personalized dry eye treatment. Could genetic factors or specific biomarkers predict which patients will respond most rapidly to Cequa? Further research is needed to explore these possibilities. We may also see the development of even faster-acting cyclosporine formulations or novel drug delivery systems designed to maximize ocular surface penetration and minimize systemic absorption. The trend towards minimally invasive and targeted therapies is likely to continue, with a focus on restoring the natural tear film and reducing inflammation at the source.
The study’s sponsor, Sun Pharma, is actively investigating further applications of Cequa, and the ophthalmology community is watching closely. This research isn’t just about faster surgery prep; it’s about a potential paradigm shift in how we approach and manage the pervasive problem of dry eye disease, offering hope for quicker, more effective relief for millions.
