ABSTRACT
Purpose: To analyze the determinants of satisfaction and postoperative visual function
after cataract surgery in 3 settings in The Netherlands.
Setting: University Hospital Maastricht (outpatient care), Atrium Medical Center Heerlen(inpatient care), and Medical Center Maastricht Annadal (outpatient care), Maastricht,
The Netherlands.
Methods:This cross-sectional study consisted of 150 patients of 50 years and older who
had first-eye phacoemulsification with intraocular lens implantation. Data were collected
by a written questionnaire. The following parameters were measured: medical outcome,
postoperative function, patient satisfaction with medical outcome and hospital care,
and overall patient satisfaction.
Results: In general, patients were very satisfied (mean score 8.43 on a 10-point scale
ranging from 1 very bad to 10 excellent). The 3 centers did not differ regarding the
patient satisfaction (P .092). However, postoperative visual function (P .012),
counseling (P .010), and waiting time (P .001) were different among the settings.
Patient satisfaction with hospital care had a stronger correlation with overall satisfaction
than patient satisfaction with the medical outcome (r 0.669 versus r 0.543,
respectively).
Conclusions: A causal model of patient satisfaction was tested, indicating that satisfac-
tion was related to the patients preoperative expectations and the quality of care given
during the hospital stay and follow-up at the outpatient clinic. This emphasizes the
relevance of patient education (to set realistic expectations) and counseling (need for
care) by hospital staff in a cataract surgery setting. J Cataract Refract Surg 2000; 26:

It is generally agreed that modern cataract surgery iseffective in terms of postoperative increase in visionand safe with respect to the low incidence of surgical
complications.1 However, the measurement of visual
function after cataract surgery is a better outcome mea-
sure than visual acuity alone.2 Therefore, outcome stud-
ies in cataract surgery should focus on both functional
status and quality of life after surgery.3
Although after cataract surgery, most patients ben-
efit from an increase in visual acuity and visual function
and an improvement in quality of life, their satisfaction
may be limited because of a lack of perceived quality of
care. By combining the evaluation of functional and
technical quality-of-care aspects, clinician and patient
evaluations of quality of care can be related.4

A general problem of satisfaction studies is the
high number of satisfied patients, which accounts for
low sensitivity of measurement methods.5 To im-
prove the sensitivity of the study, problem definitions
are based on a classification of satisfaction into 3 di-
mensions: satisfaction with cure (the medical outcome),satisfaction with care given during hospital stay and
follow-up in the outpatient clinic, and overall satis-
faction. A research model was formed to map the
expected relationships between the research variables
(Figure 1).
This study analyzed the determinants of satisfaction
and postoperative function in patients who had cataract
surgery. Three treatment settings were compared, pro-
viding data on cataract surgery on an inpatient and out-
patient basis.
Patients and Methods
The study population consisted of 3 subgroups
based on the institution at which cataract surgery was
performed. One group of patients was treated at a gen-
eral hospital (Atrium Medical Center Heerlen
[AMCH]) on an inpatient basis, 1 group was treated at a
private daycare center (Medical Center Maastricht An-
nadal [MCMA]), and 1 group was treated at an aca-
demic hospital on an outpatient basis (University
Hospital Maastricht [UHM]). Inclusion criteria were
first-eye cataract surgery to prevent bias from earlier ex-
periences and age older than 50 years. The required
sample size of 150 patients was calculated by power
analysis.To correct for an anticipated nonresponse, 235 pa-
tients were asked to participate in the study. The re-
sponse rate to the questionnaire was 64% (150 of 235
patients). Mean age was 77.4 years 7.48 (SD) (range
54 to 90 years), 74.6 9.74 years (range 51 to 94 years),
and 72.3 9.95 years (range 52 to 89 years) in the
UHM, MCMA and AMCH groups, respectively (P.022). The male/female ratio among the 3 settings was
comparable: 21/30, 27/31, and 16/25, respectively (P.731). There were no significant differences in education
level (P .727) or civil status (P .253) parameters(Table 1).
Surgical TechniqueCataract surgery was performed from January
through July 1997 by 1 of 4 surgeons using a standard
divide and conquer phacoemulsification technique. A
3.2 mm corneoscleral incision was made and a poly-
(methyl methacrylate) intraocular lens (IOL) (SN53,
Allergan) implanted.

Outcome MeasuresThe determinants of patient satisfaction were eval-
uated by analyzing objective medical outcome measure-
ments and subjective patient evaluations. Medical
outcome parameters for patient satisfaction were post-
operative logMAR visual acuity and vision improve-
ment defined as at least2 lines on the Snellen scale.6 In
addition, the incidence of intraoperative complications,
vision in the contralateral eye, and ocular co-morbiditywere recorded. Ocular co-morbidity consisted of glau-
coma, corneal disease, age-related macular degeneration
(ARMD), diabetic retinopathy, retinal detachment, am-
blyopia, and uveitis.
A questionnaire was sent to patients 6 months after
surgery to measure subjective patient evaluations. To
evaluate postoperative function, the following variables
were studied: ability to perform specific vision-depen-
dent activities (Dutch version of the VF-14), with 1
question reflecting overall trouble with vision, 5 ques-
tions related to the patients opinion of quality of life,
and 3 questions on subjective general health. Patient
satisfaction was measured by 3 dimensions: satisfaction
with medical outcome; satisfaction with care; overall
satisfaction.
The VF-14, which has been described in detail,2was
adapted for use in The Netherlands. Considerable atten-
tion was given to conceptual and cultural equivalence
and to ensuring the instrument was translated accurately
(translation-back translation method) (Table 2). Ques-
tions 7, 9, and 10 were changed because they referred to
handwork (crocheting), a game (mahjong), and sports
(golf) less familiar to the Dutch population. Two
questions relating to cycling (during the day and
nighttime) and 1 question on the use of public
transportation, common activities for the older pop-
ulation in The Netherlands, were added. Otherwise,
the questions and scoring were performed as described
by Steinberg et al.2
The VF-14 scores ranged from 0(worst level of function) to 100 (best level of func-
tion/no disability).2,7
Validity and reliability of the Dutch version of
VF-14 were tested by an expert panel and in a pilot
study in a fashion similar to that reported by Alonso
et al.8 Cronbachs alpha was similar to that in the
original VF-14 ( 0.98), and factor analysis
supported the Dutch version of VF-14 to be a single
index of visual function. The criterion validity of the
VF-14 instrument was assessed by examining the corre-
lation between VF-14 scores and visual acuity and be-
tween VF-14 scores and patient satisfaction with their
vision. The correlation between the VF-14 and visual
acuity and between the VF-14 and patient satisfaction
with vision was 0.28 and 0.64, respectively. These values
are comparable to those in the study by Steinberg et al.2
In addition, patients were asked to rate their overall
amount of trouble with vision. Response options were
4 none; 3 a little; 2 a moderate amount; 1 a
great deal.7,9

Patients opinions about their postoperative quality
of life and subjective general health were measured on a
3-point scale. They were asked whether their quality of
life (self-management, feelings of loneliness, life satisfac-
tion, activity, happiness) or general health (1 got
worse, 2 stayed the same, 3 got better) had changed

postoperatively. Face validity was tested by an expert
panel and a pilot study among patients.
Response options for satisfaction with medical out-
come were 1 very dissatisfied; 2 dissatisfied; 3
neither satisfied nor dissatisfied; 4 satisfied; 5 very
satisfied. In addition, patients were asked whether theirvision and visual function had changed as expected. Re-
sponse options were 3 better than expected; 2 as
expected; 1 less than expected.
To evaluate patient satisfaction with care, the
SERVQUAL service quality measurement scale10 was
used. This questionnaire was designed to be applicable
across a broad spectrum of services. It was empirically
evaluated for its potential usefulness in a hospital service
environment by Babakus and Mangold.11 Minor
changes were made to tailor the instrument to the spe-
cific characteristics of the department of ophthalmol-
ogy. Translation into Dutch was based on translations
by Kunst and coauthors.12 Content validity was tested
by an expert panel and a pilot study among patients as
described by Babakus and Mangold.11 The final scale
consisted of 13 quality-perception statements measured
on a 5-point scale, with endpoints labeled very good
(score 5) and very poor (score 1). Factor analysis revealed
3 dimensions: education, counseling, and waiting time.
Reliability analysis of these dimensions resulted in
Cronbachs alphas of 0.84, 0.88, and 0.59, respectively.Patients were also asked to rate their satisfaction with
care on a 5-point scale on which 1 very dissatisfied
and 5 very satisfied.
Overall satisfaction was scored on a categorical vi-
sual analog scale ranging from 1 (very bad) to 10 (excel-
lent). In addition, a have it again score, based on an
intention-to-return score developed by Babakus and
Mangold,11was formulated as follows: If I had to un-
dergo a second eye cataract surgery, I would want to
receive my treatment there again. This statement was
measured on a 5-point scale on which 5 strongly agree
and 1 strongly disagree.
Statistical AnalysisDescriptive and inferential data analyses were per-
formed using the SPSS 7.0. In preparation for data re-
duction, a correlational analysis was performed. A mean
relative score [sum score/(number of items missing
values)] was calculated in scale construction to solve the
problem of missing values. The research model was
tested by multiple linear regression. The level of signif-
icance for this study was P .05.Ordinal data based on multi-item factors were in-
terpreted as interval data in the statistical analysis as
described by Tabachnick and Fidell13 and Swanborn.14
Because various items are related to the same conceptand sum scores are calculated, reliability of this proce-
dure is high. The assumption of an underlying normally
distributed continuum was checked by item analyses in
which the following indicators were taken into account:
internal consistency (Cronbachs alpha), skewness, kur-
tosis, median and mean values, and distribution.
Results
Response Versus NonresponseResponse and nonresponse groups were compared
with respect to sex, setting, complications, ocular co-
morbidity, preoperative and postoperative vision, and
vision improvement. No significant difference was
found between respondents and nonrespondents (for
ordinal variables, 1-way analysis of variance; for nominal
parameters, chi-square test).
Objective Medical OutcomeVisual acuity improved in 88.8% of cases (Figure 2,
Figure 2. (Nijkamp) Improvement in visual acuity, logMAR (solid
bars preoperative; cross-hatched bars postoperative).

Table 3). Preoperatively, 91.8% of the patients had a
visual acuity worse than 20/40 on the Snellen scale; post-
operatively, the median score was 20/25. There was no
significant difference among the 3 settings in preopera-
tive and postoperative visual acuities (P .580; P.710) or improvement in visual acuity (P .229). In 2cases, posterior capsule rupture without vitreous loss
occurred.
Medical outcome was correlated to pre-existing oc-
ular pathology (r 0.264) and preoperative visual acu-ity (r 0.282). The incidence of ocular co-morbidity isshown in Table 3. There was no significant difference
among settings in the incidence of ocular co-morbidity
(P .517); 27.3% of the study population sufferedfrom pre-existing ocular pathology.
Subjective Patient EvaluationsPostoperative function. Mean score for postoperative
visual function on the Dutch version of the VF-14 was
80.79 25.31, 92.17 14.53, and 86.73 16.94 for
AMCH, MCMA, and UHM, respectively (P .012,Table 4). The determinants of visual function were post-
operative visual acuity (r0.283) and general health(r 0.331). Regression analysis showed no significantrelation between logMAR visual acuity in the contralat-
eral eye (mean 0.36 0.43) and visual function (P.264).
The median score for overall trouble with vision was
3.00, 4.00, and 3.00 for AMCH, MCMA, and UHM,
respectively (P .023, KruskalWallis). Five patientsfrom the 3 settings stated they were bothered very much
by their postoperative vision in everyday life (score 1 on
the overall amount of trouble question). Four of these
patients had pre-existing ocular pathology (glaucoma,
ARMD, diabetic retinopathy, or retinal detachment). In
the other patient, the IOL power was incorrect; the
achieved minus the predicted refraction was 6.79
diopters.

Sixty-one percent of the patients stated their general
health did not change as a result of the cataract surgery.
However, 31.5% of patients reported that their general
health had improved after cataract surgery (mean
3.40 0.87). No significant difference was found
among the 3 settings (P .881).Mean quality-of-life scores were 2.22 0.45,
2.31 0.35, and 2.28 0.39 for AMCH, MCMA, and
UHM, respectively (P .524), with 62.7% of patientsreporting that their quality of life had improved after
surgery. In patients who stated their quality of life was
worse postoperatively, visual acuity did not improve af-
ter surgery.
Patients opinions about postoperative quality of life
were related to subjective general health (r 0.563) andvisual function (r 0.303). Civil status (living togetherversus alone) did not affect the predictive value of a
patients opinion of quality of life.
Satisfaction with medical outcome. Scores for meansatisfaction with medical outcome were 4.12 1.17,
4.51 0.79, and 4.16 0.98 for AMCH, MCMA, and
UHM, respectively (P .089). Eighty percent of re-spondents gave a score of 4 or 5 (satisfied or very satis-
fied) on the 5-point scale. Nine patients stated they were
dissatisfied or very dissatisfied (score 1 or 2) with the
results of surgery. These patients had pre-existing eye
disease. The determinants of this satisfaction score were
analyzed by a series of singular linear regression analyses.
As proposed in the research model (Figure 1), visual
function and patient reports of change in the quality of
life were mediators in the relationship between objective
medical outcome or general health and satisfaction with
medical outcome, respectively (Figure 3).
Perceived quality of care. Mean scores for quality ofcare were 4.45 0.51, 4.48 0.56, and 4.34 0.65
for AMCH, MCMA, and UHM, respectively (P .43);90.0% of patients reported the quality of care was satis-
factory (score 4 or 5). Patients evaluated the waitingtime for cataract surgery the least positive aspect of care
(Table 5). Significant differences were found in waiting-
time scores among the 3 centers: 2.61 0.83, 3.61
0.77, and 2.62 0.79 for AMCH, MCMA, and UHM,
respectively (P .001). Waiting time for cataract sur-

gery did not predict patient satisfaction with care (P.992).
The mean scores for patient education were 3.54
1.01, 3.79 0.80, and 3.43 1.02 for AMCH,
MCMA, and UHM, respectively (P .120); 20.0% ofpatients rated the education they received as poor (score
1 or 2).
Mean scores for patient counseling were 4.25
0.54, 4.50 0.49, and 4.20 0.58 for AMCH,
MCMA, and UHM, respectively (P .010). Regres-sion analysis indicated that counseling by ophthalmolo-
gists accounted for a greater part of satisfaction with
quality of care (r 0.674) than did patient education(r 0.534).
Overall satisfaction. Mean overall satisfactionscores were 8.37 1.30, 8.66 1.24, and 8.18
1.31 for AMCH, MCMA, and UHM, respectively
(P .146); 91.0% of respondents wanted to betreated in the same center if they had to have second-
eye surgery. The median have it again scores were
4.00, 5.00, and 4.00 for AMCH, MCMA, and UHM,
respectively (P .083).The following parameters were predictors of overall
satisfaction: whether preoperative expectations of med-
ical outcome were met (r 0.407), satisfaction withquality of care (r 0.669), and evaluation of patientcounseling (r 0.674). Patient education and counsel-ing were more strongly correlated with overall satisfac-
tion than medical outcome (r 0.669 versus r 0.543).
Discussion
Studies have proved the usefulness of patient ques-
tionnaires for outcomes evaluation of cataract sur-
gery.2,1518 Several instruments have been developed to
assess subjective visual disability and self-rated quality of
vision in patients with ocular disease.
We chose the VF-14 questionnaire, developed by
the Cataract PORT group, because it has proven test
retest reliability, responsiveness, and international valid-
ity in cataract patients specifically.8,9,19 We modified
the VF-14 for the Dutch population and showed valid-
ity and reliability comparable to the internationally val-
idated VF-14 instruments by Alonso et al.8
Our study found that cataract surgery is an effective
treatment in terms of improvement in visual acuity,
postoperative visual function, and patient opinion of
quality of life. This multidimensional influence of cata-
ract surgery was manifested in a high rate of satisfaction(80.0%) with medical outcome. These findings are
comparable to those of previous studies.9,20,21
The high rate of success achieved by modern cata-
ract surgery1 has created a situation in which patient
expectations of postoperative visual function are very
high; in most cases, such expectations are fulfilled.22
One must be careful in interpreting these positive results
with regard to response rates, however. A nonresponse of
36% can compromise generalization of results. There
were, however, no significant differences among respon-
dents and nonrespondents on available data (sex, setting,
complications, co-morbidity, preoperative and postop-
erative visual acuities, and vision improvement).
Satisfaction studies of patients, the consumers of
care, should also focus on the quality of care given dur-
ing treatment. The Medical Outcomes Study23 advised
including the following variables in outcome studies:
clinical endpoints, functional status, general well-being,
and satisfaction with care. However, few studies have
focused on all 4 outcomes.21,24

Our study compared 3 settings regarding compa-
rable dimensions of outcome: clinical endpoints, vi-
sual function, patient opinion of postoperative quality
of life, subjective general health, and patient satisfaction
with medical outcome and care. Analysis of variance
showed significant differences among the groups in age,visual function, patient evaluation of counseling, and
the waiting time. Although the visual function score was
significantly better in the MCMA group than the
AMCH group, determinants of visual function, post-
operative visual acuity, and general health did not
differ among the settings. Although age differed signifi-
cantly among the 3 settings, regression analysis revealed
that the difference in visual function could not be ex-
plained by the difference in age. Further research is
needed to explain the difference in visual function
among settings.
The differences in evaluation of patient counseling
at MCMA and UHM can be explained by the difference
in the physicianpatient relationship at the 2 settings. At
UHM, an academic hospital, the patient is treated by
various doctors. At MCMA, patients are seen by only 1
or 2 ophthalmologists, which likely benefits the doctor
patient relationship.
Patient waiting time also varied significantly among
the 3 centers. Patients at MCMA had to wait 3 months
to be treated; however, the waiting time at the other 2settings was about 1 year. The patient evaluations reflect
this difference. However, no direct relationship was
found between evaluation of the waiting time and pa-
tient satisfaction with care. This might be explained by
the supporting role of patient education; when patients
are adequately informed about waiting time, they are
often willing to accept a longer time.
Multiple linear regression analysis showed that pa-
tient counseling had more predictive value than medical
outcome with regard to overall patient satisfaction. This
emphasizes the relevance of patient support and educa-
tion by hospital staff in a cataract surgery setting.
In conclusion, to improve overall patient satisfac-
tion after cataract surgery, more emphasis should be
placed on meeting patient expectations of postoperative
vision and visual function. In general, we believe that
current medical outcomes of routine cataract surgery
are excellent and, therefore, quality improvement
should focus more extensively on patient education and
counseling.
