Abstract Details
Purpose:
To assess the refractive outcome of intra ocular lens implantation [IOL] in children with cataract below five years of age.
Setting:
Institutional setup, Kasturba Hospital, Manipal
Methods:
It was a retrospective study of children with cataract, less than 5 years of age, during the period 2006-2016. All the patients underwent lens aspiration with primary posterior capsulotomy [PPC] and anterior vitrectomy with intraocular lens (IOL) implantation. Eyes without IOL implantation were excluded from the study. IOL power was calculated using SRK II formula. IOL was selected based on the rule of seven. Follow up period varied from 2 months to 96 months. Amblyopia treatment was given wherever necessary. Intraocular pressure, refraction and fundus examination was done during the follow up visits. Residual refractive error was corrected with spectacles.
Results:
19 eyes of 13 patients were included in the study. There were 4 male and 9 female patients. 6 patients had unilateral cataract.The age at presentation ranged from 4 months to 5 years, [Mean 22.20 months]. On last follow up, 9 eyes (47.36%) had visual acuity[VA] > 6/12, 3 eyes [15.78%) had VA between 6/60 to 6/12, 8 eyes [42.10%]VA < 6/60. In one eye foldable IOL was explanted and replaced with a rigid IOL in sulcus, intraoperatively as the PPC gave way and the IOL got decentered. None of the cases developed secondary glaucoma.
Conclusions:
Patients with bilateral cataract showed satisfactory visual outcome when compared to unilateral cases. Significant refractive surprise [>1D] was seen in 8 eyes. 5 eyes had myopia ranging from -1.25D to -4.25D. Under correction, ranging from +1D to +3D was seen in 3 eyes. Hence, we conclude accurate IOL power calculation in children < 5 years of age is still a challenge to the surgeon.
