The Refractive Change after Secondary Intraocular Lens Implantation

ABSTRACT

The authors analyzed one hundred and forty-six consecutive patients(146 eyes) receiving secondary intraocular lens implantation from May 1983 to September 1990 in respect to refractive change. The results were as follows 1. The secondary implantation is gradually increased year by year and age range of that becomes younger than before. 2. ACL is replaced with PCL according to the introduction of transs-cleral fixation techmque. 3. The postoperative corrected visual acuity shows no difference between ACL group and PCL group. 4. The change of keratometric reading between before and after secondary IOL implantation shows 66.1% within 1 diopter. 5. The final refractive error shows no difference between ACL group and PCL group. 6. The final change of refractive error in relationsphip between with IOL power calculation and without that shows no different change. 7. The postoperative complication shows that after-cataract is the most common in PCL group and glaucoma in ACL group. The incidence of complication is not different between the two groups.
