This is an interventional treatment trial for Cataract

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria

  1. Male or female subjects 18 years of age or older.
  2. Willing and able to understand and sign an informed consent form prior to any study-related procedures.
  3. Willing and able to follow study instructions, and able to be present for the required study visits/assessments for the duration of the study.
  4. Diagnosis of cataract in both eyes scheduled for sequential bilateral elective cataract extraction by phacoemulsification and posterior chamber IOL implantation not combined with any other surgery except femtosecond laser.
  5. Minimum endothelial cell density (ECD) in both eyes of greater than or equal to 2000 cells per mm2.
  6. Fully vaccinated against COVID-19, as evidenced by vaccination record.

Key Opthalmic Exclusion Criteria

Ophthalmic:

  1. Have a history of or current uveitis, macular edema (cystoid or diabetic), diabetic retinopathy, retinal vein occlusion and neovascular glaucoma, corneal conditions such as keratitis, corneal edema or advanced macular degeneration, which in the opinion of the investigator would interfere with study assessments and confound the data.
  2. In the opinion of the investigator or reading center, have confluent central corneal guttatae, multiple central guttatae greater than a single cell, or corneal disease or abnormality that would prevent specular microscopy corneal scans.
  3. Aphakia or low vision or monocular.
  4. Have had any intraocular surgery, glaucoma surgery (including but not limited to filtering surgery like trabeculectomy, Ahmed valve, etc) or cornea/refractive surgery within the past 6 months or anticipate a need for eye surgery (including laser) during the study period.
  5. Use of prostaglandin (PG) analogues within 60 days prior to Screening or during the course of the study.
  6. Subjects with clinically diagnosed Fuchs' Endothelial Corneal Dystrophy (FECD)/ history of keratoplasty.
  7. Subjects for whom an intra-ocular or glaucoma device procedure is planned during the cataract procedure, during study participation or has been previously undertaken.
  8. Have a current retinal detachment or history of blunt trauma in either eye.
  9. Subject who in the opinion of the surgeon has a high risk of the posterior capsule being compromised/zonular dehiscence during cataract surgery.
  10. Intraoperative complications during the cataract surgery including posterior capsule rupture, zonular dehiscence, non-placement of Posterior Chamber Intra Ocular Lens (PCIOL), vitreous prolapse, lens fragments in the vitreous, placement of Anterior Chamber Intra Ocular Lens (ACIOL), uncontrolled bleeding /hyphema.
  11. Known sensitivity to any component of the product (e.g. fluoroquinolone or polyurethane sensitivity), or to topical therapy used during course of study (e.g., povidone iodine, or anesthetics).
  12. Used fluoroquinolone antibiotics (topically, orally or systemically) during the 4 weeks before screening visit.

5. Study Description

Brief Summary
Open label controlled interventional study in eyes in up to 12 subjects (24 eyes) scheduled for uncomplicated bilateral cataract surgery on separate days.
Detailed Description
This is a multicenter, open label, controlled, pairwise, interventional study in eyes in up to 12 subjects (24 eyes) scheduled for uncomplicated bilateral cataract surgery on separate days. Eligible individuals provide informed consent; and are screened for inclusion in the study. Once eligible, subject eyes will be randomized to determine which eye will receive the first surgery. After the first surgery, study participants will receive the control treatment consisting of commercially available topical medications. For the second cataract surgery, study participants will receive a single Levofloxacin Ocular Implant in the posterior sulcus in the surgical eye at the end of cataract surgery. No sham dosing will be conducted in the eyes in the control arm.
