Patient Satisfaction,Dry Symptoms in Patients Cataract Surgery in NHS Patients Treated With Prophylactic Preservative-free Lubricant Eye Drops (AEONTM Repair, and AEONTM Protect Plus): A Randomized, Prospective, Controlled Study.

Patient satisfaction and dry symptoms in patients undergoing routine uncomplicated cataract surgery in NHS patients treated with prophylactic phosphate-free, preservative-free lubricant eye drops (0.3% cross linked sodium hyaluronate, AEONTM Protect Plus and0.15% Sodium Hyalu-ronate with vitamins A and E, AEONTM Repair): A randomized, prospective, controlled study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of this study is to investigate the routine use of such lubricating drops in a randomized, prospective methodology in patients undergoing uncomplicated cataract surgery in the NHS setting. As these drops are provided with the intraocular lens, if found to be of benefit in reducing dry eye problems such a study might provide evidence for the universal implementa-tion of post-operative ocular lubricant drops

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
