[The explantation and implantation of artificial crystalline lenses]
Unlabelled:
THE PURPOSE of the study is to evaluate the causes of explantation and replacement of different types of intraocular lenses.
Material And Method:
We performed a study of 1060 eyes operated for cataract in the University Eye Hospital between 1992-1996, following the number of explantation and replacement of intraocular lenses (IOL), the types of IOL and the causes of explantation.
Results:
We performed 8 explantation of IOL (0.75 g) for pseudophakic bullous keratopathy (1 case), chronic uveitis (3 cases), secondary glaucoma (2 cases), suppurative uveitis (1 case), cystoid macular oedema (1 case). From the 8 explantation of IOL, 3 were anterior chamber intraocular lenses (AC-IOL) and 5 posterior chamber intraocular lenses (PC-IOL). We performed reposition in 4 cases of IOL. The most frequent cause of explantation was chronic uveitis and secondary glaucoma.
Conclusion:
Explantation is indicated in certain cases of IOL complications without response on medical treatment.
