Abstract:
1.5mm)and received CTR scleral fixation.Visual acuity before and after surgery were examined.IOL tilt and decentration were measured with PentaCam system.Complications were also recorded.Main Outcome Measures Postoperative visual improvement,IOL position and complications.Results At the last postoperative examination,best corrected visual acuities of all eyes were increased(P=0.000).The mean IOL tilt was 4.33?2.96?before and 4.11?2.05?after CTR fixation,the mean decentration was 2.56?0.90mm before and 1.19?0.71mm after.No significant differences were found in IOL tilt before and after CTR fixation(P=0.844),but there were significant differences in IOL decentration(P=0.009).Posterior capsular opacification was found in 8 eyes(20.5%)during the follow-up period,and 2 eyes(5.1%)received Nd:YAG posterior capsulotomy.1 eye received IOL scleral fixation because of capsule rupture during CTR implantation.2 eyes suffered from temporary IOP elevation after surgery.No other severe complications occurred.Conclusions Phacoemulsification with CTR and IOL implantation is effective and safe for congenital subluxated lenses.CTR scleral fixation is a necessary supplement for severely subluxated lenses and progressive cases.
