Abstract: Objective To investigate the efficacy and safety of capsular hooks and modified capsular tension rings (MCTR) for the treatment of moderate to severe lens subluxation during phacoemulcification with intraocular lens (IOL) implantation. Design Retrospective case series. Participants 15 cases (19 eyes) of moderate to severe lens subluxation in which range of lens dislocation was from 135° to 225° in Beijing Intech Eye Hospital from January 2009 to January 2011. Methods  Data were collected from total 19 eyes of 15 patients with moderate to severe lens subluxation, who received the phacoemulsification and IOL implantation in the assistance of capsular hooks and MCTR. The range and location of lens dislocation were observed preoperatively. Visual acuity, refractive power, intraocular pressure and anterior segment of the eyes were observed postoperatively. The average follow-up period was 16.4±4.8 months. Main Outcome Measures Visual acuity, complications. Results The MCTR was implanted successfully in all 19 eyes (100%). At the last follow-up, visual acuity improved in all 19 eyes with no complications such as IOL asymmetry, high intraocular pressure, MCTR incarceration, serious posterior capsular opacification or vitreous hernia. Conclusion The capsular hooks and modified capsular tension rings are helpful for the treatment of moderate to severe subluxated lens during phacoemulsification. It can prevent from occurring of intraocular lens decentration and decrease the surgical complications. (Ophthalmol CHN, 2012, 21: 52-55)
