AIM: To evaluate the safety and efficiency of the open capsule-single loop intraocular lens(IOL)ciliary sulcus fixation for the treatment of congenital subluxation lens.

METHODS: Ten patients(13 eyes)with congenital subluxation lens were included. After conventional tunnel incision and continuous curvilinear capsulorhexis, iris hooks were used to fix the luxation lens helped the phacoemulsification(phaco)procedure and IOL implantation into capsular bag. The inferior capsular bag was opened. The IOL prolapsed from the bag and was half packaged. The lower loop was fixed to the ciliary sulcus by suturing to avoid the possible dislocation.

RESULTS: The best corrected visual acuity(BCVA)was increased in all of the patients without any serious complication. The IOL kept stable in 12mo.

CONCLUSION: The iris hooks can fix subluxation lens and facilitate the phaco. Open capsular bag makes IOL half-free and single suture the lower IOL loop in ciliary sulcus. It can avoid dislocation of the IOL due to progressive weakening of the zonular fibers.
