About this study
Official title: The Effects on Betadine 5% Penetration When Using Lidocaine 2% Jelly Versus Topical Tetracaine 0.5% for Topical Phacoemulsification Cataract Surgery.
The purpose of this study is to determine if there is a difference on the penetration of betadine 5% when using lidocaine 2% jelly versus topical tetracaine 0.5% in topical cataract surgery. This will be assessed comparing bacterial colony count and species by taking swabs from the eye surface before and after the topical anesthesia has been administered.
Read the detailed description
The purpose of this research study is to show that using Lidocaine2% jelly before surgery as an anesthetic (keep you from feeling touch or pain) for cataract surgery does not block the antiseptic (cleans and kills germs) effect of Betadine5%.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Ln(Bacterial Colony Count) From Pre-antibiotic Administration to Post Study Medication Swabs
Within 3 hours from time of culture acquisition, the samples will be vortexed for 30 seconds and 100µl aliquots will be plated onto 5% sheep blood and chocolate agar plates. These plates will be incubated with 5% carbon dioxide at 35˚ C for 72 hours. After 72 hours all plates will be read for colony count and identification of all isolates will be performed using routine microbiological methods. The natural log of bacterial bacterial colony count will be used for the outcome measure.
Measured: (1) Pre-antibiotics swab, and (2) Post-study medication (pre surgery)
Number of Bacterial Species in Pre-antibiotic Administration and in Post Study Medication Swabs

Questions about this trial
What is this clinical trial studying?
A study testing tetracaine 0.5% and Lidocaine 2% Jelly in people with Cataracts, run by Hermann Eye Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Jun 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Ln(Bacterial Colony Count) From Pre-antibiotic Administration to Post Study Medication Swabs (time frame: (1) Pre-antibiotics swab, and (2) Post-study medication (pre surgery)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00827073, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2014; AzTrials last refreshed its copy on 8 Nov 2026.
