Chronological Versus Non-chronological Phacoemulsification Training
A study testing Chronological phacoemulsification training and Non-Chronological phacoemulsification training in people with Age-related Cataract, run by Sohag University at 1 site in Egypt.
Trial summary
The goal of this clinical trial is to compare between two methods used in training residents on phacoemulsification. The residents were classified into two groups; the first group were trained on surgical steps in a chronological order, while the second groups in non-chronological order. Read more about this study

About this study
Official title: Chronological Versus Non-Chronological Method in Phacoemulsification Training for Ophthalmology Residents
The goal of this clinical trial is to compare between two methods used in training residents on phacoemulsification. The residents were classified into two groups; the first group were trained on surgical steps in a chronological order, while the second groups in non-chronological order. The outcomes included surgical competency, success rate and incidence of complications.
- Conditions
- Age-related Cataract
- Being tested
- Chronological phacoemulsification training, Non-Chronological phacoemulsification training
- Keywords
- Phacoemulsification, Learning curve in cataract surgery, Training of ophthalmology residents
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Chronological phacoemulsification trainingProcedure or surgery
Residents trained step-by-step in the natural order of phacoemulsification (incision, capsulorhexis, hydrodissection, phacoemulsification, irrigation/aspiration, IOL implantation, wound closure).
Non-Chronological phacoemulsification trainingProcedure or surgery
Residents trained initially on selected steps (e.g., wound construction, IOL implantation, cortical cleanup) before progressing to more critical steps such as capsulorhexis and phacoemulsification
| Study group | Role | What they receive |
|---|---|---|
| Group A | Active comparator | Not described Receives: Procedure: Chronological phacoemulsification training |
| Group B | Active comparator | Not described Receives: Procedure: Non-Chronological phacoemulsification training |
What is being measured
The primary outcome is the main question the study is designed to answer.
Success rate
Measured: From enrollment till three months after the last surgery
Secondary outcomes (1)
Incidence of complications
Measured: From enrollment till 3 months after the last surgery

Questions about this trial
What is this clinical trial studying?
A study testing Chronological phacoemulsification training and Non-Chronological phacoemulsification training in people with Age-related Cataract, run by Sohag University at 1 site in Egypt.
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 1 inclusion and 11 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: under way, not looking for participants, as of the sponsor's last update on 28 Apr 2026. 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 Egypt. 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.

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?
Success rate (time frame: From enrollment till three months after the last surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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?
