RESUMO
AIM: To observe the efficacy of phacoemulsification combined with capsular tension ring and intraocular lens implantation in the treatment of high myopia with cataract.METHODS: Retrospective study. A total of 82 cases(82 eyes)of high myopia complicated with cataract who admitted to the cataract department of our hospital from December 2021 to April 2023 were selected as study objects, and they were divided into control group(n=39)and combination group(n=43)according to whether or not the capsular tension ring was used intraoperatively. Patients in the control group were treated with intraocular lens implantation alone, and those in the combination group were treated with phacoemulsification combined with capsular tension ring and intraocular lens implantation. The preoperative and postoperative best corrected visual acuity, central anterior chamber depth, trabecular ciliary process, visual quality and complications were compared.RESULTS: At 1 mo after surgery, the best corrected visual acuity(LogMAR)of both groups increased significantly(combination group: 0.64±0.28 vs 0.12±0.14; control group: 0.62±0.26 vs 0.23±0.25, both P<0.001). Central anterior chamber depth in both groups were higher than those before surgery(combination group: 2.57±0.56 vs 1.97±0.40 mm; control group: 2.22±0.45 vs 1.89±0.37 mm; both P<0.001), and the best corrected visual acuity and central anterior chamber depth of the combination group were significantly better than those of the control group(both P<0.05). The distance of trabecular ciliary process showed no statistical significance(combination group: 0.68±0.22 vs 0.74±0.20 mm; control group: 0.74±0.19 vs 0.78±0.17 mm, both P>0.05). The visual quality scores of the combination group were all higher than the control group at 1 mo after surgery [watching TV: 3.00±0.38 vs 2.22±0.46 points; reading books: 2.85±0.42 vs 2.21±0.44 points; night vision: 2.71±0.34 vs 2.37±0.41 points; fine operation: 2.82±0.38 vs 2.33±0.40 points, all P<0.001]. The incidence of complication in the combination group was significantly lower than that of the control group(33% vs 14%, P<0.05).CONCLUSION: Phacoemulsification combined with capsular tension ring and intraocular lens implantation can effectively promote the recovery of visual function, improve the structure of chamber angle, and reduce the incidence of complications in the treatment of patients with high myopia and cataract.
RESUMO
Objective To compare the clinical efficacy of uniportal complete thoracoscopic and conventional three -port thoracoscopic lobectomy in the treatment of lung cancer. Methods A total of 62 cases of lung cancer from January 2012 to January 2016 received lobectomy in our hospital.According to admission sequence number, the patients were randomly divided into either single-port group(n=31)or three-port group(n=31).The single-port group was given uniportal thoracoscopic lobectomy, and the three-port group was given traditional three-port operation of VATS lobectomy.We compared the two groups with intraoperative and postoperative conditions and follow-up outcomes. Results The operations were successfully completed in both groups.There were no significant differences between the two groups in operation time[(182.3 ±77.9)min vs.(177.6 ±69.2)min, t =0.251, P=0.803],intraoperative blood loss[(207.3 ±48.4)ml vs.(226.5 ±52.3)ml,t=-1.500, P=0.139], chest tube indwelling time[(5.5 ±1.6)d vs.(5.7 ±2.0)d, t=0.435, P=0.665], postoperative hospitalization time[(8.7 ±2.7)d vs.(9.0 ± 2.8)d,t=0.925,P=0.0.372],lymph node dissection number[(11.2 ±2.8)vs.(11.7 ±3.1),t=-0.666,P=0.508]and postoperative incidence of complications[9.7%(3/31)vs.12.9%(4/31),χ2=0.000,P=1.000].The VAS scores on the first and fifth postoperative day were(3.1 ±1.1)points and(1.0 ±0.7)points in the single-port group, which were significantly lower than those in the three-port group[(3.9 ±1.4)points,t=-2.502,P=0.015;(1.5 ±0.7)points,t=-2.812,P=0.007].The 62 cases were followed up for 12-36 months(mean,18.4 ±6.4 months)without recurrence and death. Conclusion Single-port thoracoscopic lobectomy for lung cancer has good curative effect and safety as compared with traditional method,being worthy of clinical application.
RESUMO
Objective To compare the clinical effects of one-stage modified capsular tension ring (MCTR) scleral fixation and second-stage capsular tension ring (CTR) capsular bag complex scleral fixation in the treatment of moderate and severe subluxation of lens.Methods Retrospective study.Thirty cases (43 eyes) of patients with moderate and severe subluxation of lens from January 2012 to December 2015 were collected.Those patients were treated with phacoemulsification cataract extraction and MCTR or CTR and IOL intracapsular implantation under local anesthesia.23 eyes in group A were treated with MCTR combined with IOL implantation and one-stage scleral fixation.20 eyes in group B were treated with one-phase CTR combined with IOL implantation and second-stage of CTR-capsular bag complex scleral fixation after 3 to 6 months.The best corrected visual acuity,location of the postoperative capsular bag complex and complication were observed at 6 months after surgery.Results Postoperative 6-month,the best corrected visual acuity ≥0.6 were in 87％,95％ of the patients m group B,and there was no statistical significance difference (P ＞ 0.05).All CTR and IOL were located in the capsular bag after surgery.Two eyes in group A and 1 eye in group B were observed with moderate contraction and off-center of capsular bag,there was no significant difference (P ＞ 0.05).All groups achieved response after YAG laser anterior capsule relaxing incisions.Early complications of postoperative (1 month):3 eyes in group A and 1 eye in group B were observed with exudative membrane in anterior chamber;5 eyes in group A and 2 eyes in group B were with transient high intraocular pressure,and there was no significant difference (all P ＞ 0.05).Long-term complications of postoperative (6 months):3 eyes in group A and 1 eye in group B were observed with after cataract,and there was no significant difference (P ＞ 0.05).All groups conducted YAG laser posterior capsulotomy.Conclusion The location stability of the capsular complex after one-stage MCTR scleral fixation or secondstage CTR capsular bag sclera fixation is good.And the treatment is effective for moderate and severe lens dislocation.
RESUMO
Objective To compare the clinical outcomes of dilator-kyphoplasty (DKP) and balloonkyphoplasty (BKP) in treatment of osteoporotic vertebral compression fractures. Methods From May 2007 to March 2009, 23 cases with 26 vertebrae were treated with DKP, while 29 cases with 29 vertebrae were treated with BKP procedures. The operating time, bleeding volume and injecting volume of cement were recorded during operation. The distribution of cement, the restoration of vertebral height and Cobb angle were observed. The patients' visual analogue scales (VAS) score and Oswestry disability index (ODI) score were evaluated after operation. Results There were no differences in operative time, bleeding volume of every vertebrae and cement injected volume between these two groups (P＞0.05). The vertebral height, Cobb angle, VAS and ODI scores were significantly improved than those of pre-operation in these two groups (P＜0.05). The height of the anterior vertebrae and Cobb angle in DKP groups were restored significantly than those in BKP groups (P＜ 0.05). There were 1 case (1 vertebra, 3.8%) underwent cement leakage in DKP groups and 5 cases (5 vertebrae, 17.2%) in BKP groups. Conclusion DKP and BKP were effective in the treatment of osteoporotic vertebral compression fractures. The height of the anterior vertebrae and Cobb angle in DKP groups were restored significantly than those in BKP groups.
