NASHVILLE, Tenn., Aug. 20, 2026 (GLOBE NEWSWIRE) -- Harrow (Nasdaq: HROW), a leading provider of ophthalmic disease management solutions in North America, today announced positive results from a prospective, randomized, contralateral-eye study evaluating IHEEZO® (chloroprocaine hydrochloride ophthalmic gel) 3%, an ophthalmic gel indicated for ocular surface anesthesia, in patients undergoing same-day bilateral intravitreal injections. The single-center, investigator-initiated study demonstrated statistically significant differences favoring IHEEZO at every measured time point.
Patients reported approximately 58% less discomfort overall in the IHEEZO-treated eye than in the fellow eye treated with proparacaine ophthalmic solution 0.5%, a statistically significant difference at all four post-injection assessments (all p≤0.048). The largest absolute treatment differences were observed immediately after injection, when discomfort is highest: 1.44 versus 3.06 at two minutes and 1.26 versus 2.82 at one hour, while lower discomfort scores with IHEEZO remained evident through the 24-hour assessment.
Millionsi of intravitreal injections are performed in the United States each year — making them among the most frequently performed procedures in ophthalmology — and they are often administered repeatedly over months or years to patients with retinal diseases. As a result, the injection experience, including patient discomfort, can become an important consideration for both patients and retina specialists, particularly in practices managing a high volume of patients who return regularly for treatment.
Study Results
IHEEZO was associated with lower patient-reported discomfort at all four post-injection assessments, measured using a standard 0-to-10 numeric rating scale:
The results showed a consistent benefit with IHEEZO throughout the 24-hour assessment period, with lower patient-reported discomfort at every time point. The largest absolute differences occurred shortly after injection, when discomfort is highest. Absolute treatment differences were 1.62 points at two minutes and 1.56 points at one hour, and lower discomfort scores with IHEEZO remained evident through the 24-hour assessment.
“Patient comfort is a larger part of the intravitreal injection experience than it is sometimes given credit for,” said Travis Peck, MD, Retina Consultants of Delmarva, principal investigator of the study. “Because each patient received both anesthetic approaches on the same day, we were able to directly compare the patient experience. Patients consistently reported less discomfort in the IHEEZO-treated eye across all time points we measured. For retina specialists who perform a high volume of injections and care for patients who return repeatedly for treatment, these are practical and clinically relevant findings.”
“These results provide new clinical evidence from a real-world practice setting supporting IHEEZO’s differentiated clinical profile versus commonly administered legacy ophthalmic anesthesia modalities – demonstrating a measurable improvement in patient-reported comfort following intravitreal injections,” said Mark L. Baum, Chief Executive Officer of Harrow. “Retina specialists work to preserve vision in patients who require ongoing treatment over many years, and the experience of each of those visits matters and ideally, should be optimized. The consistency and magnitude of the reduction in patient discomfort should strengthen physician confidence in IHEEZO’s clinical profile and support broader utilization of the product across retina practices.”
About the Study
The investigator-initiated study was a prospective, randomized, contralateral-eye comparison conducted in a private retina practice. The study evaluated 100 eyes from 50 adult patients undergoing same-day bilateral intravitreal injections. Both eyes received 2% lidocaine-soaked pledgets prior to administration of the randomized study anesthetic. In each patient, one randomly assigned eye received IHEEZO prior to injection and the fellow eye received preservative-containing proparacaine ophthalmic solution 0.5%, allowing each patient to serve as his or her own control and reducing between-patient variability.
Patient-reported ocular discomfort was assessed using a 0-to-10 numeric rating scale at 2 minutes, 1 hour, 6–12 hours, and 24 hours following injection.
