Introduction: To evaluate the safety and efficacy of new precision pulse capsulotomy (PPC) in pediatric cataract surgery

Methods: It is a retrospective study of all children (age<12years) undergoing cataract surgery using the PPC technique for anterior capsulotomy. Best corrected visual acuity (BCVA) and intra ocular pressure (IOP) were measured pre-operatively; centration and size of the capsulotomy, pupillary dilatation, surgical time and time required for PPC were measured intra-operatively; post operatively BCVA, IOP, centration and size of capsulotomy were noted. Any complications intra or post operatively were noted

Results: 11 eyes of 7 patients (mean age= 6years, range 11months to 9years, 5 boys and 2 girls) were included. Mean PPC time was 91 (±28)seconds (n=8) and mean surgical time was 31.2 (±5.6)minutes. Intra-operatively, all patients had good pupillary dilatation, well-centered, circular and complete capsulotomy of appropriate size, successful intra-ocular lens (IOL) implantation with capsular edge covering the IOL. 2 eyes had inferiorly decentered capsulotomy which was clinically insignificant. 2 eyes had increased post-operative IOP, which was controlled with anti-glaucoma medications. At an average 1month follow-up, no other intraoperative or postoperative complications were noted.

Discussion: Precision pulse capsulototmy has shown circular, centered, strong and consistent outcomes in cadaver, animal and adult human studies (1-3). We found PPC to be effective in pediatric eyes.

Conclusion: PPC is safe, precise and effective in pediatric cataract surgery with a short learning curve. No major complications or change in surgical time was noted.
