Abstract

Objective: To evaluate the outcomes of three-piece foldable intraocular lens (IOL) fixation using lamellar tunnel dissection in congenital ectopia lentis and to analyze selected factors associated with postoperative outcomes.


Subjects and methods: This prospective interventional study without a control group included 35 eyes of 19 children with congenital ectopia lentis who underwent surgery at Vietnam National Eye Hospital from February 2025 to September 2026. A three-piece foldable IOL was fixated by directly tucking both haptics into scleral tunnels without IOL-fixating sutures, fibrin glue, or flange creation. Visual acuity, intraocular pressure, IOL position, and complications were assessed during 3 months of follow-up.


Results: Mean UCVA improved from 1.52 ± 0.40 logMAR preoperatively to 0.57 ± 0.27 logMAR at 3 months, while mean BCVA improved from 1.23 ± 0.50 to 0.35 ± 0.26 logMAR (both p<0.001). At 3 months, 48.6% of eyes achieved BCVA ≥20/30 and no eye had BCVA <20/200. Haptic position was graded as good in 88.6% of eyes, and 91.4% of IOLs were centered at 3 months. Postoperative ocular hypertension occurred in 8.6% and conjunctival wound dehiscence in 5.7%; no uveitis, intraocular hemorrhage, retinal detachment, or endophthalmitis was observed. Three-month BCVA differed significantly among age groups (p=0.01) and according to preoperative spectacle correction or regular follow-up (p<0.001).


Conclusion: Three-piece foldable IOL fixation using lamellar tunnel dissection provided significant visual improvement and relatively stable IOL positioning during the first 3 postoperative months. Longer follow-up is required to assess long-term fixation stability and late complications.
