[Clinical use of capsular tension ring during phacoemulsification in subluxated lens].

OBJECTIVE: To investigate the safety of capsular tension ring implantation during phacoemul- sification in the subluxated lens. METHODS: Capsular tension ring was implanted in 13 cases (14 eyes) of subluxated lens after continuous curvilinear capsulorrhexis during phacoemulsification. The luxated area was ranged from one third to three quarters of a circle. The capsular tension ring was necessary to be fixated on sclera if the luxated area was larger than half-quarter of a circle. After the ring was implanted, phacoemulsification was performed and foldable intraocular lens (IOL) was implanted. RESULTS: The capsular tension ring was successfully implanted in 14 eyes, including 11 IOLs fixated in the bag and 3 in ciliary sulcus. IOL positions in 12 cases were normal, and in 2 eyes, had slight tilt. The most common intraoperative complication was the rupture of capsular bag, and secondly, the loss of vitreous body. CONCLUSION: Capsular tension ring implantation is safe in the patient of lens subluxation during phacoemulsification. It can prevent the IOL decentration and decrease the vitreoretinal complication.
