Abstract
Purpose:To evaluate the early postoperative change in astigmatism in pediatric patients having cataract extraction with intraocular lens implantation using sutured temporal clear corneal incision. Methods: A retrospective chart review was performed on all pediatric patients who underwent clear corneal cataract surgery with intraocular lens implantation between 12/01/2005 and 11/30/2006. Results: A total of 31 eyes of 22 patients who underwent temporal clear corneal cataract surgery and intraocular lens implantation were included. The mean patient age at surgery was 6.05 years (range 1.5 months to 17 years). Mean postoperative refractive astigmatism the first day after surgery was 2.35±1.37 diopters (D). There was a statistically significant decrease in mean postoperative astigmatism by postoperative week 1 to 1.45 ± 0.79 D. Mean astigmatism was 1.48 ± 0.98 D by postoperative months 2-4, which was not a statistically significant change from postoperative day 1. Conclusions: Postoperative astigmatism can be expected after sutured temporal clear corneal surgery in pediatric patients and decreases over time without removal of sutures. The amount of postoperative astigmatism in children requires close follow-up after pediatric cataract surgery.
Highlights
Intraocular lens (IOL) implantation at the time of cataract surgery is currently a widely accepted method of treatment for pediatric patients with cataracts [1]
We evaluated the early change in postoperative refractive astigmatism in pediatric patients after cataract extraction with IOL implantation through a 3.2mm temporal clear corneal incision closed with dissolvable suture
Our results demonstrate that early postoperative astigmatism is induced in pediatric patients after a sutured temporal clear corneal wound
Summary
Intraocular lens (IOL) implantation at the time of cataract surgery is currently a widely accepted method of treatment for pediatric patients with cataracts [1]. Because the pediatric eyes are much softer than the eyes of adults and since pediatric patients may be more prone to trauma and less compliant, pediatric clear corneal wounds are usually sutured. Since amblyopia is a concern in children, the amount of postoperative astigmatism is an important factor to consider. Postoperative astigmatism is of concern, since amblyopia treatment is usually initiated as soon as possible after cataract surgery and precise optical correction of astigmatism is needed to maximize visual improvement. We evaluate the early postoperative changes in refractive astigmatism after cataract extraction in the pediatric population using sutured clear corneal temporal wounds
