268 2014 23 4 Ophthalmol CHN 2014 Vol. 23 No.4 patients combined with high myopia. Design Retrospective case series. Participants 20 patients (20 eyes) with high myopia were performed phacoemulcificatioan and IOL implantation as control group. 20 patients (20 eyes) with high myopia were performed phacoemulcification, IOL and CTR implantation as observed group. All patients came from Beijing Tongren Hospital in Jan. 2013 to Dec. 2013. Method The visual acuity, intraocular pressure, corneal endothelium, and refraction before and after surgery in both groups were reviewed and compared. Main Outcome Measures Visual acuity, intraocular pressure, coneal endothelium, and refrection predication error. Results Predicative refractive degree in observed group and control group was (-1.29±0.34) D, (-1.16±0.39) D (P=0.31). Refractive prediction error in observed group and control group in 3 months after phacoemulcification was (1.38±0.43) D, (1.71±0.32) D, respectively (P=0.06). There was no hyperopia error in two groups after phacoemulcification. Conclusion Capsular tension ring implantation had no significant effect on refractive error in lens subluxation patients combined with high myopia. There is no necessity to additional adjusting IOL calculating formula in these patients.

Department of Ophthalmology, People s Hospital of Xinglong County, Hebei, Chengde 067300,China Corresponding author: SONG Wan-qing, Email: xinglongswq@sina.com Abstract Objective To explore the application value of trypan blue lens capsule staining in cataract surgery in Vision Recovery Project. Design Retrospective comparative case series. Participants 84 patients (84 eyes) with severe cataract in Vision Recovery Project of Millions of Poor Cataract Patients in 2012-2013 were recruited. Methods Patients were randomly divided into observation group(42 patients, 42 eyes) and control group(42 patients, 42 eyes). Observation group received 0.1 ml trypan blue capsule staining before continuous curvilinear capsulorhexis during phacoemulsification, but control group were not stained. Main Outcome Measures State of intraoperative lens capsule staining, success rate of continuous curvilinear capsulorhexis, visual acuity, intraocular pressure, degree of anterior chamber inflammation, corneal edema and posterior capsular opacification. Results The lens anterior capsule of all patients in observation group was stained as light blue after the trypan blue staining. The success rate of continuous curvilinear capsularhexis was 97.6% in observation group and 78.6% in control group (P=0.003). The difference of visual acuity, intraocular pressure, anterior chamber inflammation, corneal edema after surgery were no statistically significant (all P>0.05). 3 months after surgery, significant posterior capsular opacification appeared in one case in observation group and six cases in control group ( P=0.027). Conclusion The continuous circular capsulorhexis and phacoemulsification in Vision Recovery Project could become easier to perform after anterior capsule staining with trypan blue.
