New study aims to make cataract surgery safer by measuring ultrasound energy
NCT ID NCT07468877
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two different machines used during cataract surgery to see which one uses less ultrasound energy. The researchers will measure the total energy delivered into the eye while removing the cloudy lens. Thirty adults with cataracts in both eyes will take part, with each eye treated using a different machine.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Healthy patients 18 years or older undergoing uncomplicated sequential bilateral cataract surgery with phacoemulsification and IOL implantation * Expected to undergo sequential cataract surgery in both eyes * Must have bilateral nuclear sclerosis cataracts classified using LOCS III as grade 3 or above (see appendix III) * Both eyes will be operated on by the same surgeon * Have the ability to consent for study and procedure planned Exclusion Criteria: * Patients under 18 years of age. * Complex cataract cases involving zonulopathy (e.g., pseudoexfoliation syndrome, traumatic zonular weakness) that may require use of zonular support devices during surgery (e.g. capsular hooks) and/or implantation of capsular tension rings or other zonular support devices, and in the investigator's judgment, may interfere with the surgical procedure or study outcome measures. * Require mechanical pupil expanding devices (e.g., iris hooks, Malyugin rings, etc.) * Undergoing femtosecond laser-assisted lens fragmentation. * Surgical complications, in the opinion of the investigator, occurring either intraoperatively or postoperatively (including capsule tears, iris trauma, or decentered intraocular lens) and not attributable to the study device or study design. * Prior ocular surgery (including intraocular, oculoplastic, corneal or refractive surgical procedure) performed within the last 3 months or at any time that in the investigator's clinical judgment, if it interferes with the outcome measures of this study. * Presence of endothelial cell dystrophies and/or corneal comorbidities. * History of intraocular inflammation (e.g., uveitis, iritis). * History of retinal edema or presence of a clinically significant epiretinal membrane that, in the investigator's clinical judgment, may interfere with the outcome measures of this study. * History of retinal surgery (e.g.retinal detachment repair, membrane peel) involving vitrectomy. * Dense brunescent cataract that in the investigator's clinical judgment, may interfere with the outcome measures of this study.
