| Purpose: To evaluate the controversy of early and delayed pars plana Vitrectomy (PPV) for posteriorly dislocated lens fragments after phacoemulsification. Patients and Methods: A Prospective study was conducted on all consecutive cases (30 patients) with parsplana Vitrectomy performed for retained lens fragment. In first group: 15 eyes (50%), PPV were performed within 1 week of cataract extraction and in second group 15 eyes (50 %), PPV were performed more than 1 week post cataract extraction from January 2016 to November 2017. Results: In the first group, 67 % of the patients had a final Visual acuity of 0.3 or better, but 27% of them achieved a final Visual acuity of 0.5 or better. The mean improvement of Visual acuity in the 1st week was 0.13 ±0.14, in one month 0.18 ±0.16, 0.28 ±0.21 in the 3rd month and 0.37 ±0.23 at the end of the 6th month .In the second group, 34 % of the patients had a final Visual acuity of 0.3 or better, but 14% of them achieved a final Visual acuity of 0.5 or better. The mean improvement of Visual acuity in the 1st week was 0.09 ±0.07, in one month 0.14±0.09, 0.19±0.13 in the 3rd month and 0.24±0.17 at the end of the 6th month. Conclusions: The visual outcome of the first group in our study is better than that of the second group but with no statistical significance (P value more than 0.05), the results did not indicate an association between clinical outcomes and whether the patient had an early or delayed PPV, However, there was evidence that early PPV may produce better outcomes than delayed PPV. | ||
