title: Complications after primary and secondary transsclerally sutured posterior chamber intraocular lens implantation.
abstract: This retrospective study analyses and compares early complications during the first month after primary and secondary posterior chamber implantation of transsclerally sutured IOL. The analysis covered medical records of 65 patients who underwent posterior chamber implantation of transsclerally sutured IOL at the Eye Clinic in Rijeka between 1998 and 2003. In 30 patients (group 1) lenses were implanted in one eye during complicated cataract surgery (primary implantation), whereas 35 patients (group 2) had lenses implanted afterwards (secondary implantation). There were 77 early complications, equally represented in both groups, i.e. 40 in (51.9%) the first and 37 (48.1%) in the second group. The most frequent complications were: vitreous hemorrhages 24.7% (14.3% and 10.4%), cystoid macular edema 19.5% (9.1% and 10.4%), keratopathy 14.3% (6.5% and 7.8%), pupil distortion 11.7% (9.1% and 2.6%), IOL decentration and tilt 10.4% (6.5% and 3.9%), high intraocular pressure 9.1% (2.6% and 6.5%), inflammation 6.5% (2.5% and 3.9%). Retinal and choroidal detachment had low incidence: 2.6% (1.3% and 1.3%) and 1.3% (0% and 1.3%) respectively. As concerns early complications, there were no statistically significant differences between the two groups, except for pupil distortion, which was more frequent in primary IOL implantation (p = 0.045). After primary implantation of IOL, the average visual acuity was 0.38 +/- 0.27, whereas after secondary implantation visual acuity was 0.52 +/- 0.21. The difference was not statistically significant.
