Abstract

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.
