Study summary

Purpose:

To examine the safety of omitting the routine postoperative eye clinic review following phacoemulsification cataract surgery.

Background:

Approximately 300000 cataract extractions are performed annually in the NHS in England, requiring a similar number of post-operative visits, the majority of which result in no change in management. A conservative estimate of 70% of visits being unnecessary suggests a potential saving to the NHS of approximately £10M annually.

What's involved:

The study involves some questionnaires during the duration of the study. These include questionnaires relating to the quality of life of the patient (conducted before the operation, and at the 3 month research clinic) and a patient satisfaction questionnaire. There is also a research clinic 3 months following the operation.

What are the risks/benefits:

There are no real personal benefits to patients on the trial. The trial aims to provide very important information regarding the safety of discharging patients immediately after surgery. However the trial could potentially save many thousands of unnecessary hospital visits each year.

Read the detailed description

Method:

The method presented is based on the method employed successfully by one of the applicants in an earlier stuy of the first day postoperative review following cataract surgery which has been peer-reviewed and published in the scientific literature. An earlier draft has been presented to a patient panel and has the benefit of external review by a potential steering group.

Patients undergoing routine elective phacoemulsification cataract surgery will be randomly assigned to either a routine review at 4-6 weeks post-operatively (routine care) or to be discharged from the cataract service immediately post-operatively. All patients will be advised to see their own optometrist at 4-6 weeks for new spectacles if appropriate and will then be reviewed in a research clinic at 3 months post operatively.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2014 to primary completion in Aug 2016, 30 months.

Of 316 non-industry interventional studies with no phase under Cataract, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 30. This study's 30 months is above that.

Counting every sponsor, half of 501 studies reached it within 17 months; a quarter within 9 and three quarters within 29.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
