About this study
Official title: Evaluation of Postoperative Pain in Cases Undergoing Cataract Surgery Under Topical Anaesthetic Versus General Anaesthesia
Comparison between cataract surgery under local versus general anesthesia regarding postoperative pain, complications and patient satisfaction and need for rescue analgesic intake after surgery The results will be followed up at 24 hrs, 1 week and after one and half month following the surgery.
Read the detailed description
This prospective randomized controlled study will be carried out on 50 adult patients. Written informed consent will be taken from all prospective cases.
The cases will be selected having (ASA1), (ASA II) or (ASA III) physical status in the age range between 20 and 70 years old with cataract eye disease.
This study will be performed in Alexandria Main University Hospital, Egypt. Patients will be followed up at 24 hours, 1 week, and 6 weeks after surgery.
The following measurements will be recorded
- Pain will be assessed prior to surgery and after surgery using VAS score at 24 hours, 1 week, and 6 weeks after surgery.
- Need for analgesic intake after surgery will be assessed for the first 48 hours
- Complications after surgery as irritation, infection ,and foreign body sensation were assessed
- Patient satisfaction will be assessed.
- Being tested
- Topical Anaesthesia group, General Anaesthesia group
- Medical subject headings
- Cataract
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Topical Anaesthesia groupDrug
Also called Topical group
This group of patients will only receive topical anaesthesia for Cataract surgery
General Anaesthesia groupDrug
General Anaesthesia will be given to this group undergoing cataract surgery
| Study group | Role | What they receive |
|---|---|---|
| Group under general anesthesia for cataract surgery | Active comparator | Patients undergoing cataract surgery will receive general Anaesthesia using intravenous injection and inhalational anaesthetics Receives: Drug: General Anaesthesia group |
| Group under topical anaesthesia | Active comparator | Patients will receive topical anaesthesia for cataract surgery Receives: Drug: Topical Anaesthesia group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post operative pain
Postoperative pain will be assessed using the Visual Analogue Scale (VAS), ranging from 0 (no pain) to 10 (worst pain imaginable).
Measured: At 24 hours, one week and 6 weeks following surgery
Secondary outcomes (1)
1-complications after surgery 2-Patient satisfaction will be measured using the IOWA Satisfaction with Anaesthesia Scale (ISAS), which ranges from 6 (very satisfied) to 3 or less (dissatisfied).
Complications including hypotension, nausea and allergic reaction will be assessed after surgery and 24 hours later. satisfaction assessment will evaluate patient safety, pain control, comfort, nausea, interaction with the surgical team, willingness to repeat the anaesthetic, and relaxation during and after surgery. Patient satisfaction will be recorded at one week and six weeks postoperatively.
Measured: Up to 6 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Topical Anaesthesia group and General Anaesthesia group in people with Topical Anaesthesia and General Anesthetic Drug Adverse Reaction, run by Alexandria 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 1 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 17 Dec 2025. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Post operative pain (time frame: At 24 hours, one week and 6 weeks following 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2025; AzTrials last refreshed its copy on 6 Nov 2026.
