Abstract

PURPOSE: To report the results of secondary posterior chamber intraocular lens (PC-IOL) implantation in pediatric cataract eyes with microcornea and/or microphthalmos. METHODS: Retrospective studies were conducted by reviewing the charts of 26 eyes of 15 patients with secondary PC-IOL implantations for microcornea and/or microphthalmos associated with cataract in children between 1999 and 2002. The corneal diameter was 9.5 mm or less at the time of secondary PC-IOL implantation. Preoperative examinations were conducted for bilaterality, corneal diameter, eye abnormalities and systemic abnormalities. Postoperative results were evaluated in terms of visual developments, refractive changes, axial length measurements and the occurrence of complications. The follow-up period was at least one year after secondary PC-IOL implantation. RESULTS: Age at the first diagnosis for cataract with microcornea and/or microphthalmos was 2.7 months on average. Among 15 patients, 8 (53.3%) had a family history. All patients received an initial irrigation and aspiration, posterior capsulectomy, and anterior vitrectomy at 0.8 years (0.1-3.3 years) of age and a secondary PC-IOL implantation surgery at 6.7 years (1.6-17.2 years) of age on average. The postoperative follow-up period was 2.1 years (1.1-4.3 years) on average. The average power of the implanted PC-IOL was +21.2D. Postoperative complications were secondary glaucoma in two eyes, secondary pupillary membrane formation in two eyes. Best corrected visual acuities in 20 eyes in children capable of the vision test at the last follow-up were 20/60 or better in 11 eyes, 20/80 to 20/150 in eight eyes, and 20/200 or worse in one eye. CONCLUSIONS: The secondary PC-IOL implantation in pediatric cataract with microcornea and/or microphthalmos is recommended as a means of improving vision, but must be conducted carefully to avoid possible complications.
