·AIM:To evaluate the therapeutic effect of capsular tension ring(CTR)implantation in cataract surgery.·METHODS:Twelve cases 12 eyes with subluxation lens had cataract surgery.After continuous curvilinear capsulorhexis(CCC)and phacoemulsification,foldable intraocular lenses(IOL)were implanted after CTR implantation in the capsular.·RESULTS:Twelve cases(12 eyes)with subluxation lens underwent CTR and posterior chamber IOL implantation successfully.All patients’ visual acuities were improved.IOL were in the good position.No significant complications occurred.·CONCLUSION:CTR may prevent IOL deviation and decrease complications in surgery.·
