Abstract
Purpose: To evaluate the refractive outcome of congenital cataract surgery with intraocular lens (IOL) implantation at Vietnam National Insitute of Ophthalmology.
Methods: A cross-sectional descriptive study on eyes that underwent surgery for congenital cataract with IOL implantation when children were from 2 to 16 years old at the Pediatric Department of Vietnam National Institute of Ophthalmology from June 2019 to June 2020. The follow-up period was 3 months postoperative.
Results: Of the 32 eligible patients (53 eyes), 21 had bilateral cataract, and 11 unilateral. The mean age of patients at surgery was 6.22 ± 2.86. All eyes had residual refractive outcome, most were hyperopia (62.3%). The mean spherical equivalent refraction were +0.94 ± 2.38D. 96.2% eyes had difference between the residual refraction and the desired correction postoperative
(range 0.0 – 9.0D). 98.1% eyes had astigmatism (mean +1.73 ± 0.95D), most were inverse
astigmatism (60.4%). 96.9% eyes had a difference in refraction between both eyes. 45.3% eyes had the final best corrected visual acuity (BCVA) ≥ 20/60. The patients in the unilateral cataract group had the residual refraction and the difference in refraction between both eyes higher than the bilateral cataract group. The older the surgical age, the smaller the residual refraction outcome.
Conclusion: All eyes had residual refractive outcome, most were hyperopia. The patients in the unilateral cataract group had worse outcome than the bilateral cataract group.
