PURPOSE: To investigate the effect of secondary intraocular lens (IOL) implantation on binocular vision in @entity1 with unilateral @entity4118 uncorrected consecutively for 3 years or more. METHODS: This study included nine @entity1 who underwent secondary IOL implantation, but had remained in a unilateral aphakic state, without being corrected, for at least 3 consecutive years at the time of the secondary IOL implant. They also had a postoperative best-corrected visual acuity of better than 20/40 in both eyes. All @entity1 underwent an ophthalmologic examination including best spectacle-corrected visual acuity and binocular alignment. Stereoacuity was evaluated using the Titmus Stereotest and a stereoacuity of 100 sec of arc or better was designated as "good" stereoacuity. Binocularity was determined using the polarized 4-dot test at distance and at near and the reporting of 4 dots were used to establish fusional ability. RESULTS: Four of the nine @entity1 (44.4%) showed the highest stereoacuity of 40 sec of arc and another four @entity1 (44.4%) showed a stereoacuity of 50 or 60 sec of arc. Only one @entity1 showed "poor" stereoacuity of 200 sec of arc. All the @entity1 could fuse at near and at distance on the polarized 4-dot test. @entity892 and @entity1319 were not found in any @entity1 . CONCLUSIONS: Secondary IOL implantation can provide good binocular vision even in @entity1 with unilateral @entity4118 who had not been corrected for 3 years or more.
