⁴Selçuk Üniversitesi Meram Tıp Fakültesi, Göz Hastalıkları A.D., Konya, Prof. Dr. Purpose: To determine the clinical and surgical features of eyes with retained lens fragments during cataract surgery managed by pars plana vitrectomy (PPV) and to evaluate the treatment results at 6-month follow-up.
Mateirals and Methods: Medical records of 29 patients who underwent PPV for retained lens fragments and were followed-up at least for 6 months between June 2005 and December 2008 were reviewed.
Results: Retained lens fragments were removed with PPV and phacofragmantation in 24 eyes and with a vitreous cutter in 5 eyes. Before PPV, 9 eyes had intraocular lenses (IOLs) at the ciliary sulcus, 2 had IOLs subluxated into the vitreous, and 1 had a posterior chamber IOL located in the anterior chamber. Fourteen eyes had IOL implantation into the ciliary sulcus during the same session as PPV. Of the 6 eyes that were left aphakic during PPV, 2 had IOLs implantation to the ciliary sulcus and 4 had scleral fixated IOLs within the subsequent 2-month period. One eye had trabeculectomy 4 weeks after PPV and 1 eye had rhegmatogenous retinal detachment 7 weeks after PPV. At the 6-month follow-up, corrected visual acuity was beter in eyes operated on within 3 days of cataract surgery compared to eyes operated more than 3 days after cataract surgery (0.64±0.27; 0.43±0.26; respectively, p=0.04).
Conclusions: PPV is an effective and safe surgical treatment in eyes with retained lens fragments. The improvement in visual acuity is better in eyes operated on within 3 days of cataract surgery. Keywords : Cataract surgery, retained lens fragments, pars plana vitrectomy
