Cataract Phacoemulsification Study, Postoperative Outcomes, 24th Apr
Summary
An observational clinical study (NCT07550907) was registered on ClinicalTrials.gov examining the impact of phacoemulsification tip location during cataract surgery on early postoperative corneal changes and visual acuity outcomes. The study will enroll patients with age-related cataracts and use intraoperative OCT imaging to evaluate tip positioning across three locations (supracapsular, iris-lens diaphragm, and endocapsular). The registration documents the study protocol and outcome measures without creating any regulatory obligations.
“In patients with age-related cataracts undergoing phacoemulsification, does the location (supracapsular, iris-lens diaphragm, or endocapsular) of the phaco tip affect postoperative corneal changes and visual acuity at early postoperative stage?”
About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.
What changed
A new observational clinical trial was registered on ClinicalTrials.gov under NCT07550907 on April 24, 2026. The study aims to evaluate whether the location of the phacoemulsification tip (supracapsular, iris-lens diaphragm, or endocapsular) affects early postoperative corneal changes and visual acuity in patients undergoing cataract surgery for age-related cataracts. Participants will receive intraoperative OCT imaging to assess tip positioning, with postoperative corneal changes and visual acuity measured as primary outcomes.
This is a clinical study registration providing transparency into planned research. It does not create compliance obligations for any regulated entity. Healthcare providers and clinical investigators conducting cataract surgery research may reference this registration for study design context, but no regulatory or reimbursement-related actions are triggered by this document.

The Impact of Surgical Procedures on Postoperative Outcomes in Cataract Phacoemulsification and Analysis of Related Factors
Observational NCT07550907 Kind: OBSERVATIONAL Apr 24, 2026
Abstract
The goal of this observational study is to evaluate the location of phacoemulsification tip measured by intraoperative OCT during cataract surgeries and its impact on early postoperative changes of cornea and visual acuity. The main question it aims to answer is:
In patients with age-related cataracts undergoing phacoemulsification, does the location (supracapsular, iris-lens diaphragm, or endocapsular) of the phaco tip affect postoperative corneal changes and visual acuity at early postoperative stage? Eyes having phacoemulsification for cataracts will receive intraoperative OCT imaging to evaluate the location of the phaco tip during surgery, and corneal changes and visual acuity will be measured postoperatively.
Conditions: Age-related Cataract
Interventions: cataract surgery
