RESUMO
Purpose: To compare the performance of nylon sutures to that of polyglactin sutures in pediatric patients undergoing cataract surgery. Setting: University of Campinas (UNICAMP), Campinas, São Paulo, Brazil Design: A prospective, randomized, partially masked, single-site clinical trial. (https://clinicaltrials.gov/ct2/show/NCT03812640). Methods: A total of 80 eyes from 80 patients who underwent pediatric cataract surgery were randomized into two groups in block sizes of four. Group A consisted of 41 patients whose surgical incisions were sutured with polyglactin 10-0 material. Group B consisted of 39 patients whose surgical incisions were sutured with nylon 10-0 material. The primary outcome was frequency of suture-related complications in each group. Secondary outcomes were the frequency with which suture removal was necessary. Results: The incidence of suture-related complications within 6 months of follow up was 0 out of 41 eyes (0.00%) in the polyglactin group and 17 out of 39 eyes (43.59%) in the nylon control group (p < 0.001). In all of the eyes with suture-related complications, the sutures were promptly removed. The most frequent complications were vascularization near the suture (17.95%) and loose sutures (17.95%). No ocular or systemic study-related adverse events were observed. Conclusions: Polyglactin sutures were found to be safe and effective for pediatric patients undergoing cataract surgery. Their lower rate of complications and reduced likelihood of removal (and the subsequent need for general anesthesia) make their use preferrable to that of nylon sutures. This study represents the first controlled randomized clinical trial to compare nylon sutures to polyglactin sutures in pediatric patients undergoing cataract surgery.

RESUMO
OBJECTIVE: To estimate the prevalence of blindness in the elderly population of Campinas, Brazil, and to describe the coverage and quality of cataract surgery services in the area. METHODS: A brief assessment of cataract surgery services (using the "RACSS" (Rapid Assessment of Cataract Surgical Services Method) was conducted using random cluster sampling, with a sample composed of 60 clusters of 40 people aged 50 years or older. Visual acuity (VA) was measured and the lens status observed by direct visual ophthalmoscopy. From the selected sample of 2,400 subjects, 92.67% were examined. RESULTS: Blindness (VA < 3/60 with available correction) was found in 1.98 % (2.03 % among male subjects, and 1.94 % among female subjects). The prevalence of blindness varied with age, from 0.2%, in the group from 50 to 54 years, to 7.2% in those above 80. Cataract was the main cause of blindness (40.2%) followed by suspected posterior segment disorders (18.2%), diabetic retinopathy (15.9%), and glaucoma (11.4%). The cataract surgical coverage was of 93% (VA < 3/60) and 82.18% when the criterion was VA 6/60 in the best eye. The main reasons the subjects did not receive surgical treatment were: fear of undergoing surgery, 11.1%; lack of awareness about the condition, 16.7%; waiting for maturity, 16.7%; and contraindication to surgery, 44.4%. CONCLUSION: Cataract is the major cause of blindness in Campinas. Education on eye diseases, their prevention and treatment must become part of the city's public healthcare policies.

OBJECTIVE: To evaluate patient characteristics and satisfaction in an outpatient service at a university hospital, aiming at obtaining subsidies for standardization of a quality assessment program. METHOD: Patient-representative sample was selected. It consisted of users of the Ophthalmology Outpatient Service at the Hospital das Clínicas, Universidade Estadual de Campinas (UNICAMP). A structured questionnaire was applied through interview, including the following variables: personal characteristics (gender, age, literacy, job), type of appointment (new patient, follow-up), waiting time for the first appointment, opinion regarding ease of access to the hospital, assistance at the front desk, time spent in the waiting room on the appointed day, quality of care, degree of satisfaction with the consultation and general evaluation of the assistance. RESULTS: The sample was characterized by patients with low literacy and socioeconomic level; 21.7% had a steady income. The majority of them think that it is easy to obtain an appointment. According to patients, the mean waiting time for the appointment was 94.6 minutes and 45.3% of them received no orientation after the appointment. Final evaluation of the quality of assistance was positive and patients were satisfied with the provided assistance. CONCLUSION: Although a high level of satisfaction regarding the provided service was observed, when the various factors that can affect patient satisfaction are considered, users reported limitations as concerns quality. Evaluation allowed a better knowledge about the provided service in a university hospital and pointed to the possibility of implantation of quality assessment routines.
