Secondary implantation of open-loop, flexible, anterior chamber intraocular lenses

Abstract

PURPOSE: To assess the results of implantation of secondary, open-loop, flexible, anterior chamber intraocular lenses (IOLs) and compare the findings with those of other published studies. SETTING: A combined ophthalmology and ear, nose, and throat hospital in Middlesbrough, Cleveland, England. METHODS: This retrospective study comprised 81 patients who had secondary implantation of a flexible, open-loop, anterior chamber IOL by the one surgeon. The incidence of postoperative complications was ascertained, and best corrected preoperative and postoperative visual acuities were compared. RESULTS: Two serious complications occurred: one severe loss of vision that is still under investigation and one retinal detachment that was repaired with good residual visual function. Of all 81 patients, 92.5% were within one Snellen line of their preoperative best corrected visual acuity. These results compare favorably with those of other published studies. CONCLUSION: Using an open-loop, flexible, anterior chamber lens for secondary implantation is still an acceptable way to treat aphakia. The poor reputation of these lenses is undeserved.
