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 (chi(2)=259.730, P<0.001). For aged patients, both Phaco and SICS could significantly improve visual acuity with no significant difference (chi(2)=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 (chi(2)=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.展开更多

The results revealed that this combined operation can make most of them get useful visual acuity, although they were often accompanied with several comlicated eye injuries. We think the most important thing is to choose suitable opertion time, the reasonable operation method and take close followup after operation.展开更多

Therefore, we aimed to study the effects of different cataract surgery techniques on endothelial cell loss in transplanted corneal grafts. Methods： A total of 54 patients who received complicated cataract surgery in post-penetrating keratoplasty （PKP） eyes at the Shandong Eye Institute between February 2001 and June 2014 were included, and clinical records were reviewed. Baseline demographic details, clinical characteristics, endothelial cell density （ECD）, and best-corrected visual acuity （BCVA） were recorded. Wilcoxon rank-sum test and Wilcoxon signed-rank test were used to test the equality of medians. A regression model was constructed to compare the reduced rate of ECD. Results： Of the 54 eyes included in this study, extracapsular cataract extraction （ECCE） was performed in 34 eyes of 33 patients （ECCE group） whereas phacoemulsification was performed in 20 eyes of 20 patients （phacoemulsification group）. There was no signifcant difference in the median age （P = 0.081） or preoperative ECD （P = 0.585） between the two groups. At 6 months after cataract surgery, ECD in ECCE group was significantly higher than that in phacoemulsification group （P = 0.043）. In addition, the endothelial cell loss rate in ECCE group was significantly lower than that in phacoemulsification group at 2 months （P = 0.018）, 4 months （P 〈 0.001）, and 6 months （P 〈 0.001） after cataract surgery. Endothelial cell loss rate after cataract surgery increased over the 6-month study duration in both ECCE group （P 〈 0.001） and phacoemulsification group （P 〈 0.001）, but phacoemulsification resulted in a greater reduction in ECD than that of ECCE in transplanted corneal grafts （P 〈 0.001）. There was no signifcant difference in postoperative BCVA between the two groups （P = 0.065）. Conclusion： ECCE is more suitable than phacoemulsification in cataract surgery in complicated cataract after PKP.展开更多
