A prospective randomized clinical trial of phacoemulsification vs manual sutureless small-incision extracapsular cataract surgery in Nepal

PURPOSE: To compare the efficacy and visual results of phacoemulsification vs manual sutureless small-incision extracapsular cataract surgery (SICS) for the treatment of cataracts in Nepal. DESIGN: Prospective, randomized comparison of 108 consecutive patients with visually significant cataracts. METHODS: settings: Outreach microsurgical eye clinic. patients: One hundred eight consecutive patients with cataracts were assigned randomly to receive either phacoemulsification or SICS. intervention Cataract surgery with implantation of intraocular lens. main outcome measures: Operative time, surgical complications, uncorrected and best-corrected visual acuity (BCVA), astigmatism, and central corneal thickness (CCT). RESULTS: Both surgical techniques achieved excellent surgical outcomes with low complication rates. On postoperative day 1, the groups had comparable uncorrected visual acuity (UCVA) (P = 0.185) and the SICS group had less corneal edema (P = 0.0039). At six months, 89% of the SICS patients had UCVA of 20/60 or better and 98% had a best-corrected visual acuity (BCVA) of 20/60 or better vs 85% of patients with UCVA of 20/60 or better and 98% of patients with BCVA of 20/60 or better at six months in the phaco group (P = 0.30). Surgical time for SICS was much shorter than that for phacoemulsification (P < .0001). CONCLUSION: Both phacoemulsification and SICS achieved excellent visual outcomes with low complication rates. SICS is significantly faster, less expensive, and less technology dependent than phacoemulsification. SICS may be the more appropriate surgical procedure for the treatment of advanced cataracts in the developing world.     

西藏地区影响老年性白内障术后视力改善因素分析

目的 分析影响西藏地区老年性白内障术后视力改善的因素.方法 对西藏地区接受白内障手术的老年性白内障278例,分析年龄、核分级、术式(超声乳化术和小切口白内障囊外摘除术)、人工晶状体度数、角膜水肿部位等对术后视力改善的影响.视力采用LogMAR视力.统计方法分别采用单因素和多因素线性回归方法.结果 (1)单因素分析:术式:超声乳化术组术后较术前视力改善(平均视力差) 0.92±0.48,小切口白内障囊外摘除术组平均视力差0.83±0.46,两种手术方式对视力改善的影响,差异没有统计学意义(P＞0.05).年龄:70-、80-年龄组分别与40-、50-、60-年龄组差异有统计学意义(P＜0.05).角膜水肿部位:弥漫性水肿(平均视力差0.52±0.42)较中央部位水肿(平均视力差0.70±0.44))对视力改善影响更大,差异有统计学意义(P＜0.05).(2)多因素线性回归分析:年龄、角膜水肿部位均对视力改善有影响,差异有统计学意义(P＜0.05).结论 (1)超声乳化术和小切口白内障囊外摘除术两种手术方式对视力提高程度无明显差异,因此在西藏地区可以根据当地条件,包括经济状况和医师具备的手术水平,来选择术式,以使患者获得最佳有用视力.(2)年龄为白内障术后视力改善的影响因素之一,随年龄增加视力改善减少,而西藏地区就医条件有限,故在西藏地区更应重视白内障的普查,强调早期发现和早期手术.(3)在角膜水肿分级无明显差异的基础上,弥漫性水肿较中央部水肿对视力改善影响更大,因此在术中应谨慎操作,尽量避免角膜内皮广泛的损伤.

Controlled clinical trial comparing biaxial microincision with coaxial small incision for cataract surgery

Purpose. Clinical outcomes of biaxial microincision versus coaxial small incision cataract surgery were compared in a prospective, controlled, paired-eye clinical study. Methods. A total of 84 eyes of 42 patients underwent cataract surgery using the biaxial microincision (B-MICS) technique in either the right or left eye. The fellow eye was to undergo cataract surgery using the standard coaxial small incision (SICS) technique. All surgeries were performed using the Stellaris Vision Enhancement System and all eyes were implanted with an aspheric microincision intraocular lens (IOL). The 1.2-mm B-MICS incision was widened to 1.8 mm for IOL insertion. The main outcome measure was the change from baseline best-corrected visual acuity (BCVA). Secondary outcome measures were uncorrected visual acuity (UCVA), surgically induced astigmatism (SIA), manifest subjective refraction in spherical equivalent (MRSE), absolute phacoemulsification time (APT), effective phacoemulsification time (EPT), mean phacoemulsification power, and endothelial cell count (ECC). Follow-up was at 1 day, 3 days, 1 week, and 2 months. Results. The treatment groups did not differ in baseline characteristics. Improvement in BCVA over baseline logarithm of the minimum angle of resolution (logMAR) was statistically significantly greater with B-MICS than SICS at 1 day (B-MICS -0.1, SICS -0.05; 95% CI -0.26 to -0.05, p=0.005). Mean improvement in UCVA from baseline was greater with B-MICS at 1 day (B-MICS -0.33, SICS -0.12; 95% CI -0.35 to -0.10, p=0.001), 3 days (B-MICS -0.39, SICS -0.26; 95% CI -0.22 to -0.02, p=0.022), 1 week (B-MICS -0.44, SICS -0.33; 95% CI -0.20 to -0.009, p=0.033), and 2 months (B-MICS -0.47, SICS 0.38; 95% CI -0.19 to +0.002, p =0.054). At 2 months, SIA was significantly lower with B-MICS than SICS (B-MICS 0.70 D, SICS 0.89 D; 95% CI -0.39 to -0.1, p=0.045), as was endothelial cell loss (B-MICS -1.4%, SICS -7.8%; p=0.05). The EPT was lower with B-MICS (B-MICS 1.60 s, SICS 2.80 s; 95% CI -1.68 to -0.77, p<0.001) with no difference in mean phaco power. Conclusions. Compared to the standard small incision technique, B-MICS showed earlier improvement in BCVA, better overall UCVA, less SIA, and less endothelial cell loss.

AIM:To evaluate the effects and safety of phacoemu-lsification(Phaco) or small-incision extracapsular cataract surgery(SICS) and intraocular lens(IOL) implantation for aged patients.METHODS:Totally 137 aged patients(149 eyes) underwent cataract operation in the case of stable systemic condition,the blood pressure less than 160/95mmHg,blood glucose less than 8mmol/L,and under the help of electrocardiogram surveillance by anesthesiologists during the operation.106 aged patients(114 eyes) underwent Phaco while 31 aged patients(35 eyes) underwent SICS.The postoperative visual acuity,corneal endothelial cell loss,surgery time and major complications were observed and analyzed retrospectively.RESULTS:The best-corrected visual acuity(BCVA) of ≥0.6 was achieved in 135 eyes(92.6%) at 1 month postoperatively(χ2=259.730,P<0.001).For aged patients,both Phaco and SICS could significantly improve visual acuity with no significant difference(χ2=4.535,P>0.05).Postoperative corneal endothelial cell loss was 18.6%,in PHACO group,the rate was 18.5%;in SICS group,the rate was 19.0%,the difference of which was no significant(χ2=0.102,P >0.05).The surgery time was different in two groups.No severe complications occurred.CONCLUSION:Both Phaco and SICS combined with IOL implantation for aged patients are effective and safe.Before surgery,detailed physical examination should be performed.When the systemic condition is stable,cataract surgery for aged patients is safe.

Intraindividual comparison of surgical trauma after bimanual microincision and conventional small-incision coaxial phacoemulsification

PURPOSE: To compare the surgical trauma after microincision phacoemulsification and small-incision coaxial phacoemulsification after implantation of conventional, foldable, hydrophobic acrylic intraocular lenses (IOLs). SETTING: Department of Ophthalmology, Medical University of Vienna, Vienna, Austria. METHODS: A prospective investigator-masked case series comprised patients with bilateral cataract who had cataract surgery on the same day. Thirty-three patients (66 eyes) were randomized. Microincision cataract surgery (MICS) was performed through 2, 1.4 mm clear corneal incisions (CCIs) using bimanual sleeveless phacoemulsification (cool phaco) in 1 eye. Small-incision cataract surgery (SICS) was performed on the other eye through a 3.2 mm CCI. In all cases, an AcrySof SA60AT IOL was inserted, in the MICS group after the CCI was enlarged. Laser flare photometry, specular microscopy, corneal endothelial cell density, and pachymetry were evaluated preoperatively and postoperatively. Intraindividual comparison and statistical analyses were performed. RESULTS: There were no relevant clinical differences or perioperative complications in either group. There were no statistically significant differences between preoperative and postoperative anterior chamber flare or endothelial cell loss. On the first postoperative day, the MICS group had statistically significantly increased corneal swelling (P = .008). Postoperatively, the mean endothelial cell density loss was higher in the MICS group (6.2%) than in the SICS group (3.10%); however, the difference between groups was not significant (P = .08) CONCLUSIONS: Microincision cataract surgery was a safe and reproducible technique. The postoperative results in the MICS group were comparable to those in the SICS group.
