Phacoemulsification in the treatment of cataract with lens subluxation

Abstract

Objective To investigate the surgical technique of phacoemulsification in the treatment of patients with cataract and lens subluxation.Methods A retrospective case series rearch.The records of 16 eyes of 16 patients who underwent surgery for cataract and lens subluxation were reviewed.Combination low energy phacoemulsification and posterior chamber intraocular lens implantation was applied in the patients with or without capsular tension ring implantation.The mean follow-up was (4.0 ± 2.3) months.The visual acuity,intraocular pressure (IOP),intraocular lens position and complication were observed.Results The postoperative visual acuities and best corrected visual acuities were improved in various degrees.The postoperative mean intraocular pressure (13.49 ± 2.32 mmHg) was significantly lower than the preoperative one (15.26 ± 3.44 mmHg) (P ＜ 0.05).The position of intraocular lens of all cases was in the center.No serious complication,such as intraocular lens dislocation,high IOP or vitreous prolapse was seen.Conclusion The low energy phacoemulsification and posterior chamber intraocular lens implantation is safety and effective in the treatment of cataract combined with lens subluxation,with slight anterior chamber reaction and few complications.
