Abstract
Purpose: :
To report the frequency of retinal detachment (RD) occurrence and the visual outcome of patients with Retained lens fragments (RLF) or dislocated posterior chamber intraocular lenses (PC IOLs).
Methods: :
A retrospective review was conducted to evaluate all cases of vitrectomy for RLF or PC IOLs at CHNO XV-XX Hospital from 2003 to 2006.
Results: :
A total of 100 eyes of 100 patients were studied with 65 cases of RLF and 35 cases of PC IOLs. The mean follow-up was 19 months. The prevalence of coexisting RD and RLF was 11% and this rate was the same in the PC IOLs group, for an overall rate of RD of 11%. The mean preoperative visual acuity was 20/270 whereas the mean final visual acuity was 20/57. In all cases, RD was treated with success whereas the post-operative visual acuity was slightly lower without any statistical difference (p>0,05). But reasons for a poor visual outcome (≤ 20/200) included RD, persistent corneal edema, age-related macular degeneration and glaucoma.
Conclusions: :
RLF or PC IOLs are potentially serious cataract surgery complications that can lead to retinal detachment (RD). Previous series of RD after vitrectomy for RLF or PC IOLs shows an incidence varying from 3 to 19%. Our study rate is in the mean compared to this series without differences between the RLF and PC IOLs groups. However it seems that RD occurring after this surgery is a prognosis factor of poor visual outcome.
