Chang-Sen Tu and Guo-Xing Xu

AIM:To investigate the situation of prevention and treatment for blindness,analyze the data and find a suitable way for prevention and treatment for blindness in rural area.METHODS:We used the random sampling method,sent the medical team to establish the long-lasting patients sifting mechanism,the medical team could organize the regular visit to the rural area,the same version checking flow sheet,standard logarithmic visual acuity chart and stenopaic spectacles were used to check the visual acuity,the imported portable slit-lamp and handheld ophthalmoscope were used to check the bottom of the eyes.In order to ensure the high quality of vision rehabilitation surgery,those who needed the operation had to accept the small incision non-phacoemulsification cataract extraction and intraocular lens implantation.The patients’ ages,gender were analyzed with statistically and samples were taken for epidemic analysis.RESULTS:We had visited the rural area for 201 times,it covered more than 200 towns,totally 23020 people had the examination,the major facts affecting the older people’s vision quality were cataract,pterygium,ametropia,and others,such as thygeson,retinopathy,glaucoma,strabismus,amblyopia,uveitis,eye tumor and orbital disease.The cataract prevalence rate was growing with age,the female had higher rate than male,it was statistically significant(P=0.005).There were 6869 people that could be applied the cataract extraction surgery,of which 5011 people had already done it.The sampling survey showed the visual rehabilitation rate was 99.2% and the disability recovery rate ws 95.0%,most patients could recover soon.CONCLUSION:The investigation of the epidemiology of rural area in Wenzhou provides us the reasons and distribution of blindness and shows us the direction of blindness prevention and treatment.Regular sifting mechanism in rural area of selecting and sending patients to have the small incision non-phacoemulsification cataract extraction is an acceptable mode in those undeveloped areas.

Initial investigation of perioperative cases of cataract surgery in primary blindness-prevention project

AIM:According to the analysis of 1061 cases(1061 eyes) of cataract surgery in primary blindness-prevention project,to explore the key processes in perioperative period in order to find a safe and effective procedure.METHODS: According to the information of 1061 cases in the blindness-prevention project in 2009,the perioperative processes were summarized and regulated.RESULTS:Among these 1061 cases who accepted cataract surgery,there were 17.0% cases with the preoperative corrected vision under hand movement,22.1% under 0.1,59.0% between 0.1 to 0.3,and 1.9% better than 0.3.267 cases(25.2%) were hyper matured cataract with/without hard nucleus.There were 2 cases(0.2%) combined with lens dislocation,13 cases(1.2%) accepted anti-glaucoma surgery,3 cases(0.3%) accepted vitrectomy surgery,and 9 cases(0.8%) suffered by obsolescence uveitis,44 cases(4.1%) corneal endothelial cell counting was less than 2000 per square centimetre.Phacoemulsification were performed in 1048 cases(98.8%) and ECCE in 13 cases.The incidence of several primary complications were separately: 27 cases(2.5%) of posterior capsular rapture,54 cases(5.1%) of corneal edema at postoperative 3 days,and 1 case(0.1%) of failure to IOL implantation.None endophthalmitis happened.In 3 months postoperation,the out of blindness rate(uncorrected visual acuity >0.1) was 97.8% and the rate(best corrected visual acuity >0.3) was 84.2%.There were about 36.7% with visual acuity better than 0.6.There were so many cases combined with kinds of fundus diseases,such as retinopathy due to high myopia(3.7%),age-related macular degeneration(3.3%),and so on.CONCLUSION:The conditions of cataract patients who joined in blindness-prevention project were very complex,not only in ocular but also in systemic.The rate combined with fundus diseases was high.In order to make the cataract surgery successful,normative processes in perioperative period are very important.

Practice and experience of preventing blindness using a mobile cataract operation vehicle in Shaanxi province for 25 years

Jing Li, Ya-Guang Hu, Xiu-E Shi, Yi Guo, Jing Guo, Yan-Nian Hui and Xian-Fu Yue — 2022/10/28 16:28:15

The“14th Five-Year” National Eye Health Plan has been released and national eye health has risen as a national strategy. Cataract is the primary blinding eye disease in our country, which seriously affects the national eye health. Shaanxi Province, an old revolutionary base area in the western of China, has a relative lower socioeconomic level and about millions of people need to undergo cataract surgery. In 1996, multi-cooperation built the mobile ophthalmic operation vehicle — “Fuming No.1” to contribute the poverty alleviation initiative in Shaanxi Province. In the past 25a, “Fuming No.1” has taken the advantage of the convenience of mobile operation vehicles, implementing operations in rural, mountainous and old areas with weak medical services in Shaanxi Province. A total of more than 480 trips have been made, with a total mileage of more than 200 000 kilometers,covering 104 counties and districts in the province, and nearly 60 000 cases of cataract operations have been completed. “Fuming No.1” bring the light, relieve the pain for cataract patients and help them better fit the world. Furthermore, “Fuming No.1” also offers free operation and intraocular lens for more than 30 000 poor rural patients and reduces medical expenses by nearly 10 million yuan, which has obtained high praise and support from the patients and all walks of life. In addition, “Fuming No.1” is also a mobile training vehicle, which could improve the operation skills of ophthalmologists. In the process of teaching and training, the operations had also been completed with high quality. In view of the unbalanced economic development in our country, “Fuming No.1” will expand service projects, innovate work models, and continue to construct eye healthy in Shaanxi province, making greater contributions to consolidating the achievements of poverty alleviation.
