This study was designed to investigate the effect of a hand massage program on anxiety and immune function in patients during cataract surgery. The hand massage program, in this study, consisted of hand massage and hand-holding. The subjects were sixty-three patients, thirty for the experimental and thirty-three for the control group, who were admitted at Kang Nam St. Mary's Hospital for cataract surgery. This study was carried out from December 10, 1997 to February 26, 1998. The level of anxiety as measured by the Visual Analogue Scale, systolic blood pressure, diastolic blood pressure, and pulse rate were measured before, after hand massage, and after hand-holding. Epinephrine, norepinephrine, cortisol, blood sugar levels, neutrophil, lymphocyte, and natural killer cell percentages also were measured before hand massage and five minutes before the end of the operation. Data were analyzed by t-tests, ANCOVA, repeated measures ANOVA, and Bonferroni multiple comparisons. The results were as follows : 1) After hand massage, psychological anxiety levels decreased significantly compared with before hand massage in the experimental group, not in the control group. After hand holding, there were significant decrease in both groups. 2) There were not significant differences on systolic blood pressure, diastolic blood pressure, and pulse rates in both groups. 3) The hand massage program decreased epinephrine, norepinephrine, and cortisol significantly in the experimental group, and increased epinephrine, norepinephrine, and cortisol in the control group. 4) There were no differences in blood sugar levels, neutrophil and lymphocyte percentages in white blood cells after the hand massage program. However, natural killer cells in lymphocytes were significantly increased in the experimental group. These findings indicate that a hand massage program could be a effective nursing intervention in decreasing the psychological and physiological anxiety levels and improving immune function in clients having cataract surgery under local anesthesia.

Our purpose is to ascertain, if possible, whether atomic bomb survivors with cataracts and epilation were more radiosensitive than those survivors with cataracts but without epilation. A major ophthalmologic survey was conducted in Hiroshima and Nagasaki in 1963-64. At that time, 2125 individuals were examined. Among these individuals, estimated eye organ doses, based on the DS86 dosimetry system, and information on the occurrence of epilation within the first 60 days following the bombings are available on 1742. In the analysis of these data we have assumed that each individual represents a sample of one from a binomial distribution, and that the occurrence of cataracts and epilation are independent biological phenomena. We got following results. The threshold for cataract induction and its 95% confidence limits have been estimated from data on the occurrence of cataract and epilation. Among the 1742 study subjects, 40 had both cataracts and severe epilation. The estimated threshold based on these cases is 0.98 sievert(Sv), with 95% lower and upper confidence bounds of 0.72, and 1.32 Sv, respectively, and is highly statistically significant. Among the 27 cases of cataracts where severe epilation was not reported, the estimated threshold is 1.74 Sv with 95% lower and upper confidence bounds of 1.21 Sv, and "not estimable". The difference between these two estimates is not statistically significant although the effect of dose is highly significant in both instances. The potential importance of biases in the DS86 dose estimates is discussed. The difference between the threshold estimated from cataract cases with epilation and that from cases without epilation is not statistically significant at the 5% or 10% level, and thus affords no support for the notion of increased radiosensitivity.

These days the posterior chamber lens implantation following the extracapsular cataract extraction has become the standard procedure except those patients who can not take it in one reason or another. In past, however, the anterior chamber lens implantation was popular for sometimes. Even now in those patient complicated by vitreous loss, the anterior chamber lens implantation following anterior vitrectomy is indicated in some cases. We have become interested in the difference of the intraocular pressure change in the patients who underwent the uneventful extra-capsular cataract extraction followed by anterior chamber lens implantation in routine manner and in those whose extra-capsular cataract extraction were complicated by vitreous loss and eventually needed the anterior vitrectomy before the anterior chamber lens implantation. We reviewed the medical records of 15 cases of the former group and 11 cases of the latter one in 1986 through 1988. There was some difference in the postoperative pressure in the two groups, but it was not statistically significant.

Purpose: The aim of this study was to investigate the distribution of age and gender, types of intraocular lens (IOL), and refractive errors in subjects who had cataract surgery. Methods: 2,217 subjects who had cataract surgery were surveyed at an optometry clinic in Chungbuk from 2010 to 2012. Information about IOL was obtained from case history, reflective and retroillumination images IOL by auto refracto-keratometer. Refractive errors were determined by objective and subjective refraction. Results: The mean age of the subjects was $71.74{\pm}10.62$ years. The number of cataract surgeries increased from 524 persons in 2010 to 888 persons in 2012. Of the subjects surveyed, 52 persons (2.3%) were under the 40 years of age, 144 persons (6.5%) were in 50s, 404 persons (18.2%) were in 60s, 1,132 persons (51.1%) were in 70s, 485 persons (21.9%) were in above 80s. Cataract surgery was significantly prevalent in more female (1,338 persons, 60.4%) than in male (879 persons, 39.6%). Types of IOL were 2,141 persons (96.6%) for monofocal lens, special IOLs such as multifocal, accommodative and toric lens were 76 persons (3.4%). The distribution of refractive errors after cataract operation were 1,588 eyes (38.5%) for simple myopic astigmatism, 327 eyes (7.9%) for simple hyperopic astigmatism, 601 eyes (14.6%) for mixed astigmatism, 1,240 eyes (30.0%) for myopia, 136 eyes (3.3%) for hyperopia, and 234 eyes (5.7%) for emmetropia. The uncorrected and best corrected visual acuity of the subjects were $0.55{\pm}0.25$ and $0.80{\pm}0.23$, respectively. Conclusions: The prevalence of cataract surgery increased with age until 70s years of age, it was more prevalent in men than women over 60s, and frequency of special types of IOL were low. Most cataract surgeries left residual refractive errors. Therefore even after cataract surgery it may need spectacles for better vision at either distance or near.

Purposes: This study aims to investigate the number of cataract surgeries and predict future trends using 13-year data. Methodology: Trends investigation and comparison of prediction methods was conducted to determine better prediction model using Major Surgery Statistics from Korean Statistical Information Service in 2006-2018. ARIMA(Auto Regressive Integrated Moving Average) was selected and prediction was conducted using R program. Findings: As a results, the number of surgeries will continue to increase. The trends was predicted to increase during January-April, and it declined over time and was the lowest in August. Pratical Implications: Therefore, it is necessary that management will be needed by continuously investigating and predicting the demand and trend for surgery to prepare an alternative to the increase.

Purpose: In this study, eye-health inequity was investigated by analyzing the relationship between household incomes and eye-health of senior citizens. Further, this study suggested the preliminary data for establishment of public eye-health policy in order to improve low income senior citizens' life quality. Methods: The data from the 2009 Survey of Korea National Health and Nutrition Examination were analyzed in this study. The objectives of the KNHNE survey were over 65 year old group (1,668 people). Main factors of eye-health (visual acuity, cataract, pterygium, intraocular pressure, retinophathy, age-related macular degeneration, diabetic retinophathy, myopia, hyperopia, astigmatism, and anisometropia prevalence) were analyzed with t-test and chi square test. Results: Low income group revealed that refractive error rate and intraocular pressure were low, however, naked eye visual acuity and corrected visual acuity were high at 0.1 to less than 0.5. On the other hands, in the high income group, there was high prevalence of hyperopia. Cataract mainly occurred at low income group besides group which maximum corrected visual acuity was below 0.8 also highly showed cataract. Moreover, the prevalence of cataract showed that it related with smoking, drinking, occupation, and education level. Conclusions: Results revealed that there was inequity of eye-health which related with socioeconomic status of the elderly. Especially, the prevalence of cataract was correlated with life quality. Consequently, establishment of public eye-health policy seems to be required for eye-health inequity of low income senior citizens.

Propose: Due to the rapid growth of medical technologies and the increasing population of older people, we investigated clinical status of ocular dimensions and visual acuity for pre and post cataract surgeries of people over age 90. Methods: From March 2007 to February 2009, we investigated eighty-two eyes of forty-eight patients who had undergone cataract surgeries at an ophthalmic clinic (Ansung, Kyungi-do), investigated maximum corrected vision, axial length, anterior chamber depth and accompanied ocular diseases before and after the surgeries based on the collected data. Results: As patients aged, axial length unchanged but anterior chamber depth decreased over all due to the increase of intraocular lens thickness, and men tended to have a higher degree than women. Seventy-one (86.6%) of eighty-two eyes showed improved corrected vision than before surgeries and forty-three (52.4%) eyes could see more than visual acuity of 0.5. Conclusions: Patients with the systemic disease and accompanied ocular disease showed low vision less than 0.5 after cataract surgery compared to same healthy age peoples. But the others improved correction visual acuity more than 0.5, so the cataract surgery was surely necessary for people over 90 years old and also the presence of ocular disease could have a great influence on correction visual acuity.

We studied the change in intraocular pressure (IOP) in 15 consecutive cataract patients who underwent extracapsular cataract extraction and posterior chamber lens implantation between Feb. 1993 and Apr. 1993 to evaluate the effect of this surgery on postoperative IOP. To evaluate the clinical usefulness of non-contact tonometer, the intraocular pressures were measured with Kowa non-contact tonometer (TM-2000, Japan) as well as Goldmann applanation tonometer. There was a decrease in IOP of $3.4{\pm}2.9$mmHg (p<0.00l) 3 months after this surgery and the intraocular pressure differences between pseudophakic eyes and contralateral phakic eyes at 3 months postoperatively were $2.4{\pm}3.8$mmHg (p<0.05). The correlation coefficient between non-contact tonometer and Goldmann tonometer was 0.8876 (p=0.001) in the postoperative 76 eyes. Therefore, our results suggest that extracapsular cataract extracion and posterior chamber lens implantation alone can be a useful surgical method in cataract patient with ocular hypertension, and non-contact tonometer was relatively accurate in measuring the postoperative intraocular pressure.
