To compare the results of secondary implantation of angle-supported anterior chamber intraocular lenses (IOLs) and scleral-fixated posterior chamber lenses.
Eye Clinic, University of Verona, Italy.
This study of 68 eyes of 60 patients comprised two groups. In Group A (n = 35), an angle-supported anterior chamber IOL was implanted and in Group B (n = 33), a scleral-fixated posterior chamber IOL. Follow-up was from 12 to 45 months.
In Group A, one eye developed a retinal detachment and another, pseudophakic bullous keratopathy. In Group B, one eye had a major intraoperative choroidal hemorrhage and two developed a retinal detachment postoperatively. All other complications were minor.
Although the rate of sight-threatening complications was about 6% for both groups, scleral-fixated posterior chamber IOLs were associated with more intraoperative and postoperative complications than angle-fixated anterior chamber IOLs, and surgery took longer. Thus, anterior chamber IOL implantation should be considered for older patients with relatively good endothelial cell counts.
