The visual outcomes and complications of intraocular lens implantation in children aged 1 year or less.
Al-Shifa J Ophthalmol Jan ;6(2):60-7.

Purpose: To present the visual outcomes and complications of intraocular lens (IOL) implantation in children aged 1 year or less. Subjects & Methods: A total of 30 consecutive eyes of 19 children undergoing cataract removal combined with IOL implantation at less than 1 year of age were evaluated. SRK-T formula was used to calculate the IOL power and emmetropic power was under corrected by 20%. After aspiration of the lens matter and posterior capsule polishing, acrylic hydrophilic foldable or PMMA rigid IOL was implanted by a paediatric Ophthalmologist. Visual acuity, refractive status and postoperative complications were recorded throughout the 12 months of follow up. Data was analyzed using SPSS version 13.0. Results: Out of 19 children, 8 (42.1%) had unilateral cataract (8 eyes), and 11(57.9%) had bilateral cataracts (22 eyes). Mean age at the time of surgery was 8.7 ( 2.5) months. Foldable IOL implantation in capsular bag was achieved in 17 (56.7%) eyes while sulcus fixation of IOL was done in 13 (43.3%) eyes. Mean post operative refraction was +5.97 (±2.60) DS. Postoperative fibrinous reaction was seen in 4 (13.3%) eyes, visually significant PCO requiring surgical posterior capsulotomy developed in 2 (6.66%) eyes while 24 eyes (80%) retained a clear visual axis during the follow up period. Conclusion: Lens matter aspiration combined with IOL implantation in children less than 1 year of age resulted in better visual outcomes with acceptable risk to benefit ratio. IOL power calculations and refractive outcomes were predicted satisfactorily using SRK-T formula with 20% under correction.
