Abstract Details
Purpose:
To compare the efficacy of plasma knife assisted posterior capsulotomy versus manual primary posterior capsulorhexis in preventing visual axis opacification in pediatric cataract surgery.
Setting:
Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi.
Methods:
Thirty one eyes of children less than 2 years with bilateral congenital cataract underwent lens aspiration with manual posterior capsulorhexis with anterior vitrectomy without IOL implantation and the fellow eye underwent lens aspiration with plasma knife assisted posterior capsulotomy with anterior vitrectomy without IOL implantation.
Thirty one eyes of children aged 2-5 years with bilateral congenital cataract underwent lens aspiration with manual posterior capsulorhexis with anterior vitrectomy and IOL implantation and the fellow eye underwent lens aspiration with plasma knife assisted posterior capsulotomy with anterior vitrectomy and IOL implantation. Parameters evaluated were visual acuity (Cardiff visual acuity chart), Axial length, Keratometry, Intra ocular pressure (IOP in mmHg) using Perkin's applanation tonometer, retro-illuminated clinical photograph for visual axis opacification analysis / quantification using EPCO software at 6th month and at the end of 1 year.
Results:
The mean age of patients in group A was 9.5483 ± 4.6104 and in group B it was 36.6452 ± 11.4587 months. There was no significant difference in visual improvement between the groups. There was no statistical significance difference in VAO score between the two techniques in all follow up visits (6 months p = 0.661, 1 year p = 0.724).
Conclusions:
The VAO after pediatric cataract surgery remains comparable in both techniques at one year. FINANCIAL INTEREST: NONE
