Investigating the Impact of Dry Eye Disease (DED) on Quality of Life

This project investigates the impact of Dry Eye Disease (DED) on the Quality of Life (QOL) of Australian patients. It begins with an introduction to DED, its prevalence, and its disruptive effects on individuals' lives. The study outlines its aims and objectives, focusing on how DED affects quality of life, its symptoms, and overall impact on patients. A literature review explores existing research on DED, highlighting gaps that this study aims to address. The methodology section details a quantitative survey approach, involving 100 DED patients in Australia, utilizing a questionnaire with closed-ended, multiple-choice, and Likert scale questions to ensure data validity. The questionnaire covers demographics, lifestyle factors, DED symptoms, the presence of other diseases, and QOL measures, including HRQOL indicators, cost of medication, productivity loss, and work performance. Data collection involves visiting clinics, obtaining informed consent, and conducting surveys either face-to-face or via phone calls. The study also addresses ethical considerations, timelines, stakeholder participation, and dissemination strategies, emphasizing the importance of understanding and addressing the impact of DED on QOL.

that causes major disruptions in the lives of people. The study explores the literature to
identify the studies already conducted on the subject and identified the gaps that are still there
and can be filled by the current research. It proposes the research methods to be used for data
collection and analysis.
Aims & Objectives
The aim of this research is to study the impact of Dry Eye Disease (DED) on the Quality Of
Life (QOL) in Australians. To achieve this aim, following research questions have to be
answered:
 How is quality of life affected by DED?
 What are the symptoms and impacts of DED on patients?
 How does DED symptoms affect the life of people?
The research questions above can be converted into objectives of the research for exploration
as follows:
 Identify the Vision related quality Of Life measures that are affected by DED
 Explore the symptoms of different types of DED and their impacts on QOL measures
 Understand the impact of DED diseases and symptoms on the quality of life of
patients
Literature review
Dry Eye Disease (DED) is one of the most common ocular-surface disorders that is faced by
around 5% of children and 33% of the adult population. The disease affects the Quality Of
Life (QOL) by causing vision impairments and other symptoms such as stinging, dryness,
and fatigue (Schlarmann, Sabine, & Schnepp, 2018). These symptoms have a direct impact
on the social and economic lives of those affected for a long duration. Typical difficulties
faced in the disease include photophobia, unstable tear film, and visual disturbances
(Tounaka, et al., 2014). DED is defined as multifactorial disease that affects the ocular
surface and tear glands of the patients causing problems like increased tear osmolarity,
blurred vision, ocular discomfort and inflammation. The disease is mostly caused due to tear
deficiency caused by excessive evaporation of tears that damages the ocular surface and
produces symptoms like irritation, dryness, itching, grittiness, soreness, stinging, pain, strain,
blurriness of vision, foreign body sensation, burning, visual disturbance, and photophobia.

Study the Impact of Dry Eye Disease (DED) On the Quality of Life (QOL)
Dry eye is one of the major symptoms of DED which can be caused or escalated by the
presence of common chronic diseases like diabetes, arthritis, thyroid, and lupus. Medications
given to patients for cure of such diseases as well as other health problems such as beta
blockers, contraceptive’s, and antidepressants can also cause the dryness of eye. DED can be
of two types that include Aqueous tear deficient and evaporative. Tear deficient DED can be
Sjogren Syndrome or non-Sjogren syndrome. Evaporative DED is mostly caused by
meibomian gland dysfunction (MGD). Several studies have already been conducted on DED
that have revealed some insights on the cause, symptoms and impacts which can be useful to
explore here. A study was conducted to rest the prevalence of dry eye disease in Southern
Nigeria involving 730 patients. It was found that age and gender had association with the
prevalence of the disease and that females were found to be more susceptible to DED with
growing age than men (Onua & Chukwuka, 2017). A cross-sectional study conducted on 301
patients with DED was conducted to explore sleeping and mood disorders found in patients
affected by eye diseases like DED. The study found that people with severe DED conditions
were having problems with bed time and duration of sleep (Ayaki, et al., 2016).
Methodology
To descriptively measure the impact of DED on QOL of patients, a quantitative survey will
be implemented. A primary quantitative research would be done using a survey which would
be conducted on 100 DED patients from Australia. Various methods that would be involved
in the research are presented hereafter along with the justifications of sample size selection,
data collection, and analysis.[My comment - This part should really describe the reasoning
behind why you chose a survey.
For example: you wish to conduct a descriptive quantitative study to describe or measure a
factor. In order to collect descriptive quantitative data, you have chosen a survey with
discrete/multiple choice questions.]
SURVEY CHOICE IN DETAIL IN METHODS SECTION
Methods
This study would involve a quantitative survey which would be conducted through voluntary
participation from patients of eye clinics in Australia. The survey has been selected as the
primary method of data collected as it would give the researcher an opportunity to collected
specific quantifiable data from multiple respondents in less time as the questionnaire would
3

Study the Impact of Dry Eye Disease (DED) On the Quality of Life (QOL)
have objectives questions that could be answered faster. [My comment - This part should
really describe the reasoning behind why you chose a survey.
I EXPLAINED IT ALREADY]
Also, the data obtained from the survey would help researcher test the same using statistical
methods that are scientific in nature and thus, would have more accuracy in results. Another
reason survey would be an appropriate method of data collection is that it is cost effective
when the sample size is large as a single questionnaire can be used for data collection and the
administration of the same is also simpler. Survey provides an opportunity to the researcher
in taking views of a large number of people and provides flexibility of taking responses by
various methods such as phone calls, online data collection, or face to face interviews. [My
comment - My given solution did not have the para - A survey has been selected as the
primary method of data collection as it allows the researcher to collect specific quantifiable
data from multiple respondents in the shortest time frame. Also, the data obtained from the
survey would help the researcher test the same using statistical methods that are scientific in
nature and thus, meaning the results would be more accurate.]
A quantitative survey questionnaire would have nearly 20 questions and it would be
conducted from 1st Nov 2018 to 30th Nov 2018. It would use a combination of different
types of questions including closed-ended discrete and multiple-choice as well as the Likert
scale questions. The question types would ensure the validity of the data to the objective the
research which is to explore the impact of DED on QOL. [I HAVE EXPLAINED EVERY
SECTION OF THE QUESTIONNAIRE IN DETAIL]
Questionnaire:
The questionnaire uses measures validated from previous studied conducted on DED. The
respondents would be invited to fill in this questionnaire prepared to explore the following
information: [Is there a validated questionnaire that measures this and rates severity? If there
is you should use it and cite it here
YOU DELETED DETAILS]
Demographics: the questionnaire would record the demographic information of patients
including age, gender, occupation, and income. Gender and occupation would be measured
4

Study the Impact of Dry Eye Disease (DED) On the Quality of Life (QOL)
on the nominal scale while age and income would make use of the ordinal scale with
differential values distributed as ranges.
Lifestyle: Physical activity, smoking behaviour, and alcohol consumption of the patients
would be measured to understand if there is a differential impact of patients of DED to their
QOL among people living different lifestyles. The patterns of activities, behaviour and
consumptions in respondents would be recorded using an ordinal scale defining their level of
engagement in each of the case.
Symptoms of DED: The symptoms experienced and the quality of life measures. Symptoms
that would be studied include fatigue, irritation, dryness, itching, grittiness, soreness,
stinging, pain, strain, blurriness of vision, foreign body sensation, burning, visual disturbance,
photophobia and issues in physical functioning. The symptoms experienced by the patients
would be recorded using nominal variables and the Likert scale that would measure the
presence of each symptom on a five differential scale identifying the level of severity.
Presence of other diseases: There are possibilities of confounding variables affecting the
findings on the impact of DED on QOL in presence of specific diseases that patients may
have. Thus, tThe questions would also record the presence of other diseases that could cause
similar symptoms to ensure if the impacts are only due to DED or could be a contribution
from other diseases like hypertension, thyroid, cancer cardiovascular, diabetes, and
dyslipidaemia. The presence of other disease would be marked by a nominal scale on which
their presence would be marked or unmarked in the data.[ Wouldn’t you screen out people
that had conditions which could confound your results?
THIS WAS EXPLAINED BUT DELETED IN YOUR FILE]
QOL: Questionnaire would note the Health-related quality of life (HRQOL) indicator to
capture data on mental and physical health of these patients and would measure their current
health status through the use of measures like general health status, physical unhealthy,
mental unhealthy, and activity limitations (Yin, Njai, Barker, Siegel, & Liao, 2016).
This data would make use of the defined scale of HRQOL measuring the impacts only on the
health-related QOS but as the results do not include lifestyle impacts other than the health
condition of the body, the researcher would also make use of other QOL measures that would
be separately recorded on the Likert scale defining the level of severity on a five-differential
scale for them. QOL measures would include measures such as cost of medication, healthcare
5

Study the Impact of Dry Eye Disease (DED) On the Quality of Life (QOL)
plan costs, productivity loss, daily activities performance impairments, loss of work days, and
work performance loss (MCDONALD, PATEL, KEITH, & SNEDECOR, 2015).
The questionnaire would be developed using objective questions with nominal and ordinal
scale variables and Likert scale along with the HRQOL scale.
Data Collection
To collect the data, the researcher would visit the clinics and take inputs from selected
patients informing them about the purpose of the survey. The researcher would be asking
questions to the patients and would be manually taking their responses on paper. The manual
consent would be taken from the respondents who would be signing that they have been
given the information about the purpose of survey and they are agreeing to provide
information as well as give permission to use the same for the purpose of the current study.
If some patients are not available during the face to face survey, the researcher would take
their contact number and would either interview them over calls or would fix up an
appointment for the later date for the survey [HAS BEEN EXPLAINED BUT IT IS
DELETED IN YOUR FILE]. In the case of the refusal from a selected patient to provide
information, the researcher would revisit the list of patients provided by the doctor and would
make selection of another patient to complete the data needed for the survey (Tounaka, et al.,
2014).
Participants
Participants would be selected from the patients coming to eye clinics in Australia on the
voluntary basis from the patients affected by any type of DED. The participants chosen
would from the young adult and adult groups with age more than 19 [do they need to be over
18? MENTIONED VERY CLEARLY]. The respondents would be selected on the basis of
certain parameters that include presence of DED, absence of any major disease other than
DED, and major impacts on the life of individuals from DED. The researcher would thus
personally select those respondents above the age of 19 with DED as a major health problem
(Gideon, 2012).

Sampling
This research would use purposive sampling as people with specific characteristics are
required to be participating in the survey. The researcher would visit 10 eye clinics from
where 100 patients would be selected and the research would try to create a balance between
gender and age groups to make the sample most representative of the affected population. A
sample size of minimum 100 is recommended for any population above 5000 to get the
definite patterns that can be generalizable [The sentence “<<detail test to show that you can
reach 95% confidence by sampling 100 people>>.” Which is asked to delete was never there
in my solution]. The sample size has been determined on the basis of the perspective of the
research on the sufficiency of data that could make a good representative of the population.
Also considering the time, budget, and logistics complications needing permissions from
doctors as well as patients has been a determining factor for the selection of the sample size.
Data Analysis
The data collected would be coded into SPSS and the statistical analysis would be performed
to identify the DED factors and symptoms that are causing impacts on the quality of life
parameters. For this correlation and regressions tests would be run between the symptoms
experienced by the patients and the quality of life measures as well as between the type of
DED and the quality of life measures. The analysis would also identify if there could be other
contributing factors to QOL problems such as other diseases and life style issues. Based on
the analysis, a model can be prepared which identifies different types of DEDs with
associated symptoms and the type of quality of life impairments that are caused due to them
(Kaplan & Fryback, 2010).
The research would make use of following data analysis methods:
Descriptive Analysis: Descriptive analysis would be used on the variables reflecting
demographics and symptoms to understand the distribution of participants in the survey with
respect to demographics and other factors including gender and age. he results of this analysis
would be presented using tables and graphical representations.
Correlation: Correlation tests would be run between the factors identifying presence of DED
and its symptoms and the factors representation the QOS. The symptoms that would be tested
in the correlation test would include irritation, dryness, itching, grittiness, soreness, stinging,
7

Study the Impact of Dry Eye Disease (DED) On the Quality of Life (QOL)
pain, strain, blurriness of vision, foreign body sensation, burning, visual disturbance, and
photophobia. The QOS factors that would be correlated with each of these symptoms would
include HRQOL measures, medication, healthcare plan costs, productivity loss, daily
activities performance impairments, loss of work days, and work performance loss.
Regression: If a significant correlation is found between the factors representing symptoms
of DED and the factors representing QOL measures then a regression test would be run on
those factors to test if there exists a causal relationship between them so that the factors that
actually caused the QOL disruptions can be identified (Engel, Jann, Lynn, Scherpenzeel, &
Sturgis, 2014).
Based on the findings of the regression, a clinical model would be proposed which would
explain how DED patients feel the symptoms and how these symptoms lead to disruptions in
their quality of life [do you need a reference list or will this be at the end of the chapter?
REFERENCES ARE ALREADY BEEB PROVIDED].
Ethical Considerations
As the research involved a primary survey in which respondents are taken the sensitive
information from, the researcher needs to take care of the ethical codes of conduct like
confidentiality, privacy, and informed consent. For this, the researcher would take a written
permission from all those participating in the survey and would keep them informed of the
objective of the survey with a promise to not use the information for any other purpose. The
collected data would be deleted once its analysis and presentation are completed. The
researcher would not take any personally identifiable information from the selected patients
like personal identification number, email ID or contact number to ensure that privacy is
maintained (Yanagawa, Takai, Yoshimaru, & Kida, 2014).
Besides these, the researcher also needs to take care of the research related codes of conduct
for ethical representation for which the researcher would need to ensure that the survey is not
biased by his own opinions and thus, after creation of the questionnaire it would be tested by
taking peer reviews before it is finalized. The researcher would also make sure that the data
collected would not be manipulated in any way and would be used objectively to present the
findings as it is. In case of any data missing, the researcher would take the confirmation from
then patient selected and would not fill the gaps just to complete the data for analysis
(Shigeyasu, et al., 2018).

Stakeholder Participation
Stakeholders of a research project are the people who affect or are affected by the project in
any way. The researcher has identified some major stakeholders of the research project who
would be involved in the project in the defined ways:
 DED patients who are participating in the survey would be answering the survey
questions for the purpose of this study and their responses would be analysed to draw
findings and conclusions
 Guide or tutor would be involved in providing guidance on how to proceed with the
research through feedbacks and the researcher would be updating him on research
progress actively
 Doctors working in the clinics from where patients are selected would be involved in
the research process as they would be providing the data on their patients to help the
9

Study the Impact of Dry Eye Disease (DED) On the Quality of Life (QOL)
researcher identify the patients to select for the survey (Siedlecki, Butler, & Burchill,
2010).
 Other students would be helping the researcher test the questionnaire to identify any
biases and suggest improvements before the questionnaire could be finalized and sent
for approval
 Healthcare community would be helped by this research as they would be shared the
findings with as it can help them take steps to improve conditions of the people and
patients affected by DED
Dissemination Strategy
The research would be communicated to the desired audience that include the patients,
academic, health communities and organizations. The organizations and communities would
be communicated through publishing of the article in related journals summarizing the
findings from the research. Patients participating in the survey would be communicated
through email by sending them the copies of synopsis highlighting the major research
findings (NIDRR, 2001). The researcher would also submit the full research report to the
university for disseminating its findings for academic advances. The journal publications
would increase the reach to the aider community of academicians in the field of healthcare.
The researcher would present the findings in national and international journals to reach out
to them (Wilson, Petticrew, Mike W Calnan, & Nazareth, 2010).
Importance
The proposed research would explore the impacts of DED on the QOL of patients in
Australia. The disease is very common in adults and is found in over 33% of them across
globe. The cause of DED could be many including other diseases and the symptoms
generated able affecting the lives of people in severe ways. With the understanding of the
factors that cause the major disruptions in the lives of patients can help the healthcare
community evaluate the real impact of DED and prescribe solutions for improvement of the
lives of people who are affected. The research findings would add value to the research
community by delivering new insights that would add to the body of knowledge on DED.
The research would help the researcher gain an understanding of what symptoms of DED
causes disruptions in QOL of people living in Australia and identify specific factors and
symptoms that are either causing or escalating the impacts on patients. With the help of the
findings obtained from this research, the causes of lifestyle disruptions could be understood
10

and based on the same, prescriptive measures could be suggested to the patients to help them
alleviate their conditions and improve their lives.
Conclusions
The paper proposes a research to be conducted on the 100 DED patients from Australian
clinics to understand the impacts of DED on QOL of the patients. It proposing conducting a
survey on the selected patients in order to identify the cause, symptoms, demographics,
lifestyle, and quality of life measures so that the identified factors can be evaluated for their
impacts caused on the QOL of people. Based on this analysis, a model can be proposed for
explaining the impacts of DED on the life of people through identification of the impacting
factors and the quality of life measures.
