February 4, 2020 updated by: yousef ahmed el-ayman, Zagazig University

Nano-Ceramic Coating for Laparoscope Lens: a Cheap Magical Solution for Lens Fogging and Smearing

The investigator tests the effectiveness of nano-ceramic coating when applied (painted) on laparoscope lens to protect it from fogging or smearing during laparoscopic operations

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

A Ceramic Coating is a liquid polymer that is applied by hand to surfaces to make them resistant to scratching, staining, rust or oxidation, as well as "hydrophilic", meaning that water or mud doesn't stick to them and so, they become much easier to clean. It was publicly commercialized in recent years for use on automobiles to preserve their gloss, protect their paint, preserve the clarity of their wind shields and headlights so as to provide better lighting and vision.

On the other hand, lens fogging and other vision-obstructing events during laparoscopic or endoscopic operations(e.g. being smeared by blood or other body fluids during operation, or having a piece of loose tissue stick to its surface that require manual removal and wiping) have been an ever-lasting concern for operators ever since the advent of the respective devices. Many techniques and methods have developed, tested and compared regarding their effectiveness in protecting the lens from such events and preserving vision clear and uninterrupted during operations. Examples of such methods are (scope warmers, FREDTM, ResoclearTM, chlorhexidine, betadine and immersion in heated saline.

In this study the investigator seeks to apply the idea of nano-ceramic coating as a new technique for achieving that goal. to the investigator's best knowledge, this idea was never conceived or tested in the field before.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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.
Outcome Measure
Measure Description
Time Frame
rate of fogging or smearing (per hour)
Time Frame: One month
The investigator calculates the number of times the lens is visibly fogged or smeared per hour of operation.
One month
rate of fogging or smearing (per single operation)
Time Frame: One month
The investigator calculates the number of times the lens is visibly fogged or smeared during a single operation.
One month
rate of extraction for cleaning (per hour)
Time Frame: One month
The investigator calculates the number of times the lens needs to be extracted from the abdomen for cleaning per hour of operation.
One month
Rate of extraction for cleaning (per operation)
Time Frame: One month
The investigator calculates the number of times the lens needs to be extracted from the abdomen for cleaning per single operation.
One month
The time consumption for lens cleaning (per hour)
Time Frame: One month
The investigator calculates the time consumption of the cleaning process as a total (in minutes) per hour.
One month
The time consumption for lens cleaning (per single operation)
Time Frame: One month
The investigator calculates the time consumption of the cleaning process as a total (in minutes) per single operation.
One month
Cleaning difficulty (per hour)
Time Frame: One month
The investigator calculates how many times the lens needed more measures for cleaning than simple wiping E.G immersion in hot saline per hour
One month
Cleaning difficulty (per single operation)
Time Frame: One month
The investigator calculates how many times the lens needed more measures for cleaning than simple wiping E.G immersion in hot saline per hour
One month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Affecting the lens function
Time Frame: One month

This is a subjective assessment measure, represented by the operators' statement about whether coating the lens affected its vision I.E whether there is a difference in acuity of vision between the coated and the non-coated lens in the absence of any fogging or smearing.

Statement is given as one of five choices:

  1. coated lens is notably better (significant difference)
  2. coated lens is slightly better (negligible difference)
  3. non-coated lens is notably better (significant difference)
  4. non-coated lens is slightly better (negligible difference)
  5. no difference
