Abstract
PURPOSE: To report longer term results of transscleral sutured intraocular lens (TSSIOL) implantation in a sizable cohort of aphakic children, who were not suitable for contact lens wear and lacked adequate capsular support for sulcus fixation of an intraocular lens. METHODS: Clinical outcome data were collated by retrospective review after surgery on 43 consecutive eyes in 32 aphakic children (mean age at implantation = 10 years; 33% < or = age 7 years). Outcome measures included visual acuity, postoperative refractive error, postoperative complications, and rate of reoperation. Follow-up averaged 37 months. RESULTS: Visual acuity improved after surgery in 70% (30) of operated eyes (in 69% or 22/32 children). Fifty-one percent (22/43 eyes) improved by two lines or more. No patient suffered a loss of acuity or exacerbation of preexisting amblyopia. Postoperative refraction was within +/-2.0 D of the predicted refraction in 93% (40/43) of eyes. Complications, with the exception of one eye (2%), were minor/transient and resolved in the first week after surgery. Complications included small hyphemas (7%, 3/43 eyes), vitreous hemorrhage (5%, 2/43 eyes), and ocular hypertension or hypotony (5%). Two eyes (5%) exhibited episodes of iris capture of the IOL optic, one of which (2%, 1/43) eventually necessitated reoperation for IOL exchange. No retinal detachments or other retinal complications were encountered. CONCLUSION: TSSIOL implantation appears to be a safe and effective method for correcting aphakia in pediatric eyes that lack adequate capsular support. Safety over a follow-up period longer than the average 3 years reported here remains to be determined. The surgery is more difficult to perform than capsular-bag or sulcus implantation and potentially carries greater risks.
