ABSTRACT
Purpose:
To evaluate the efficacy and safety of 23-gauge (23G) pars plana vitrectomy (PPV) in dislocated intraocular lens (IOL) cases: In early- and late-term follow-up.
Material and Method:
In this retrospective study, the medical records of 17 patients who underwent 23 G PPV treatment for dislocated IOL between January 2009 and June 2011 were analyzed. Detailed ophthalmologic examination was performed in all patients; intraoperative and postoperative complications were recorded.
Results:
In this study, mean follow-up time was 9.0 (4-22) months and mean age was 60.8 (8-82) years. Mean time after cataract surgery was variable (mean of 28.3 (0-80) months). Four patients had trauma history, five patients had pseudoexfoliation syndrome, and two patients had pathologic myopia. Dislocated IOL was placed into the sulcus in nine patients (52.9%). In two cases (11.7%), the IOLs were removed, and the patients were left aphakic. In two cases out of other 6 (11.7%), the dislocated IOL was changed with scleral fixation lens, whereas in the other four cases (23.5%), IOL was changed with iris claw lens. One patient (5.8%) remained at the same level of vision, while twelve (70.5%) cases increased two or more lines in BCVA. The vision was decreased in two cases. Intraocular pressure elevation controlled by medication was observed in one case. For two days, hypotony was observed in one patient.
Discussion:
23 G PPV technique is an effective and safe method for removing and repositioning of dislocated IOL in the vitreous.
