Abstract

Background: Cataract surgery is very important for the correction of visual acuity among the patients. Objective: The purpose of the present study was to assess the uncorrected visual acuity in small incision cataract surgery (SICS) with PCIOL than conventional method of ECCE with PCIOL implantation. Methodology: This cross-sectional study was conducted at National Institute of Ophthalmology, Dhaka, Bangladesh from January 1999 to December 2000 for a period of two (02) years. Patients with senile cataract were selected for study. A comparative study of changes in postoperative visual outcome and refractive status during post-operative follow up period up to 2 months were observed and documented between two groups of patients, one with suture less nonphaco SICS with PCIOL another with conventional ECCE with PCIOL. All the cataract surgery were done by the same surgeon, and in same place. All the patients were examined carefully both pre and post-operatively. For the purpose of recording, a proforma was made that includes particulars of the patient, complete history, general examination, ocular examination, relevant investigations, operation note, perioperative complications, post-operative follow-up, pre and post-operative visual acuity with keratometric reading. Result: A total of 60 eyes of cataract patients were included in the study of which 30 eyes of cataract patients were randomly selected for suture less nonphaco SICS with PCIOL and 30 eyes of cataract patients were for conventional ECCE with PCIOL.Mean age distribution (58.83±5.55 and 58.77±6.56) was similar in both groups. The unaided vision in both SICS & ECCE group at different postoperative intervals was reported. At day7 and month 1 postoperatively the result appears highly significant between the two groups. At day 1 and month 2 also shows the significant result between the 2 groups. The best corrected visual acuity in SICS and ECCE group at different postoperative intervals was measured. At day 7 and month 1 postoperatively the result appears highly significant between the two groups. At day 1 and month 2 also shows the significant result between the 2 groups.In SICS group out of 30 patients, 7(23.3%) cases acquired unaided vision 6/9 at day 1, 10(33.3%) patients at day 7,14(46.6%)patients at month 1 and 15(49.9%) patients at month 2. On the other hand in ECCE group no patient was found with vision ≥6/9 at day 1 and only one patient with vision ≥6/9 at day 7.At month 1 there were 5(16.6%) patients, and at month 2 there were 9(29.9%)patients with vision ≥6/9. Nearly 50.0% patients of SICS group achieve unaided vision of ≥6/9 within the follow up period of 02 months. Conclusion: In conclusion Uncorrected visual acuity in SICS cases were better than that of ECCE cases with sutures. Journal of National Institute of Neurosciences Bangladesh, 2019;5(2): 185-190

非晶状体小切口白内障手术与常规方法的比较观察研究

背景:白内障手术是白内障患者矫正视力的重要手段。目的:评价小切口白内障手术加PCIOL与常规ECCE加PCIOL植入术相比的未矫正视力。方法:本横断面研究于1999年1月至2000年12月在孟加拉国达卡的国家眼科研究所进行，为期2年。选择老年性白内障患者作为研究对象。观察并记录了两组患者术后视力和屈光状态的变化，一组为无缝线非晶状体晶状体与PCIOL，另一组为常规ECCE与PCIOL。所有的白内障手术都是由同一个外科医生在同一个地方做的。所有患者术前、术后均进行了仔细的检查。为了记录，制作了一份形式表，包括患者的详细情况、完整的病史、一般检查、眼科检查、相关调查、手术记录、围手术期并发症、术后随访、术前和术后视力及角膜测量读数。结果:共纳入60眼白内障患者，其中随机选择30眼进行无缝线非晶状体晶状体植入术联合PCIOL, 30眼进行常规植入术联合PCIOL。两组患者的平均年龄分布(58.83±5.55、58.77±6.56)相似。报告了SICS组和ECCE组术后不同时间间隔的独立视力。术后第7天和第1个月，两组间的差异有显著性。在第1天和第2个月，两组之间也显示出显著的结果。测量SICS组和ECCE组术后不同时间间隔的最佳矫正视力。术后第7天和第1个月，两组间的差异有显著性。在第1天和第2个月，两组之间也显示出显著的结果。在SICS组30例患者中，7例(23.3%)患者在第1天获得独立视力6/9，第7天10例(33.3%)，第1个月14例(46.6%)，第2个月15例(49.9%)。ECCE组第1天视力≥6/9的患者无一例，第7天视力≥6/9的患者仅有1例。第1个月视力≥6/9者5例(16.6%)，第2个月视力≥6/9者9例(29.9%)。sic组近50.0%的患者在随访2个月的时间内实现了≥6/9的独立视力。结论:经缝合的ECCE患者未矫正视力优于经缝合的ECCE患者。孟加拉国国家神经科学研究所学报，2019;5(2):185-190
