ABSTRACT
OBJECTIVE:To study sterility test after using Non-PVC bivalve soft-bag injection in PIVAS. METHODS:The test was divided into 3 groups according to the type of transfusion solution packaging and dispensing environment. Group 1 received Glucose solution using bivalve soft-bag,dispensed in PIVAS;group 2 received Glucose solution using bivalve soft-bag,dispensed in wards area;group 3 received Glucose solution using plastic bottle,dispensed in wards area. After puncturing 1,3,6,9 times (n=80),finished products placed in ward for 0,2,4,6 h(n=20),and then sterility test was conducted with membrane filtra-tion method stated in second part of Chinese Pharmacopoeia (2010 edition). Infusion contamination of 3 groups was analyzed at 9th puncture. RESULTS:The growth of bacteria was not found in group 1;the positive detection rate of group 2 and 3 were 2.5%and 3.8%(n=320). The total positive detection rates after puncturing 1,3,6,9 times were 0,0.4%,0.4%,7.5%(n=240);the positive detection rates of group 1 were all 0,those of group 2 were 0,1.25%,0,8.75%and those of group 3 were 0,0,1.25%, 13.75%(n=80). After 9 times of puncture,the positive detection rates of group 1 after placing 0,2,4,6 h were all 0,those of group 2 were 25%,5%,0,5%;those of group 3 were 5%,15%,5%,30%(n=20). CONCLUSIONS:The use of the Non-PVC bi-valve soft-bag injection in PIVAS can effectively prevent microbial contamination.
ABSTRACT
Objective To study the effect of double capsulorhexis combined with anterior vitrectomy in children with congenital cataract.Methods 42 (71 eyes) (age from 3 months to 14 years) underwent posterior continuous circular capsulorhexis (PCCC) and anterior vitrectomy after cataract extraction, and intraocularlens (IOL) were implanted in some eyes.The median follow-up time was 24 months.Results Among the 61 eyes of 37 patients who could do the visual examination,39 eye shada corrected visual acutiy of 0.5 or better, 16 eyes had a corrected visual acutiy of 0.3 or better;6 eyes had a corrected visual acuity of 0.3 or below.The postoperative complications included uveitis in 9 eyes,cornealede main 8 eyes,posterior capsular opacity(PCO) in 5 eyes.Some severe complications such as off centre IOL,cystoid macularedema and retinal detachment did not occur.Conclusion The double capsulorhexis combined with anterior vitrectomy and IOL implanted into eye should be a safe and effective method to prohibit after cataract in children with congenital cataract.
