Efficacy of primary implantation of flexible open loop anterior chamber intra-ocularlenses

ABSTRACT

Eighteen eyes of sixteen patients [eight males with age ranged from Thirty-two to seventy-two years with mean age of fifty-four years and eight females with age ranged from forty-five to seventy-five years with mean age of fifty-five years] were operated on in the period from November 1993 to June 1997. All eyes were implanted with flexible open loop anterior chamber lenses [AC-IOL]. At the end of the follow up period which ranged from three to twenty-one months with mean of eight months, unaided vision of six eyes was 6/12 or better and was better than 6/36 in fifteen eyes and three eyes had vision of 6/60 or less. The undesirable postoperative findings noted were deposits on intraocular lens [IOL] in three eyes, prolapse of iris round IOL in three eyes, iritis in four eyes, glaucoma in two eyes, vertically oval pupil in four eyes and hyphema in one eye of diabetic patient. In spite of these findings, flexible open-loop anterior chamber lenses are considered visually effective and relatively safe for primary implantation when impossible or inadvisable to place posterior chamber intraocular lenses
