3M.D., Ankara Special Acıbadem Hospital, Eye Clinic, Ankara/TURKEY Purpose: To determine reasons of IOL extraction and evaluate the prognosis of the patients that had IOL extraction.
Materials and Methods: We evaluate 29 patients that had anterior segment IOL extraction in Ankara Education and Research Hospital, between 2006-2010. We divide the patients into 3 groups Group 1; IOL extraction because of pseudophakic bullous keratopathy, Group 2; IOL extraction because of dislocation, Group 3; IOL extraction because of high intraocular pressure (IOP). Before and after IOL extraction, best corrected visual acuity (BCVA) was detected, biomicroscopic, posterior segment examination were done, IOP and corneal thickness were measured. Follow up periods were 1. day , 1. week, 1. month, 3. month, 6. month after operation. Then the patients were followed every 6 months.
Results: The most common symptom was visual loss in group 1 (68.2%) and group 2 (100%), visual loss (50%) and pain (50%) in group 3. The most frequently explanted IOL in group 1 was angle supported anterior chamber PMMA IOL (86.4%), one piece hydrophilic acrylic IOL (66.6%) in group 2, angle supported anterior chamber PMMA IOL (50%) in group 3. Preoperative and postoperative corneal thickness was thicker in group 1, compared with other groups (p<0.001). In group 3, preoperative IOP was higher then other groups (p<0.001). There wasn't any statistical difference between groups, after operation. In group 1, preoperative and postoperative BCVA was lower then other groups (p<0.001).
Conclusion: The most common patient symptom is visual loss in patients that had IOL extraction. IOL extraction doesn't change the level of keratopathy in pseudophakic bullous keratopathy patients.
