Insights
Pediatric cataract surgery with extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation can lead to significant postoperative complications. These issues, including posterior capsule opacification and decentered IOLs, may result in permanent visual impairment.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Background:
- Cataract surgery in children presents unique challenges compared to adults.
- Extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation is a common procedure for pediatric cataracts.
Purpose of the Study:
- To investigate the spectrum and frequency of postoperative complications following ECCE with IOL implantation in pediatric eyes.
- To evaluate visual outcomes and the need for secondary interventions after pediatric cataract surgery.
Main Methods:
- Retrospective analysis of 39 eyes from 28 children with complications after ECCE and IOL implantation.
- Evaluation of visual acuity, iridocapsular issues, and IOL-related complications.
- Interventions included neodymium:YAG (Nd:YAG) capsulotomy, membranectomy, and penetrating keratoplasty (PKP).
Main Results:
- Congenital, developmental, and traumatic cataracts were primary indications.
- Posterior capsule opacification (87.2%), updrawn pupil (38.5%), decentered IOL (33.3%), and pupillary capture (30.8%) were most frequent.
- Visual acuity improved to 6/18 or better in 19 eyes post-intervention.
Conclusions:
- Pediatric ECCE with IOL implantation is associated with a high rate of complications.
- These complications can lead to significant visual impairment if not managed promptly.
- Close monitoring and timely intervention are crucial for optimizing visual outcomes in pediatric cataract surgery.
Purpose:
To study the pattern of postoperative complications following extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation in pediatric eyes.
Setting:
Tertiary eye care center, New Delhi, India.
Methods:
A retrospective analysis of 39 eyes of 28 children referred for complications after ECCE with IOL implantation was performed. The results evaluated were visual acuity, iridocapsular problems, and IOL-related complications. Additional interventions such as neodymium:YAG (Nd:YAG) capsulotomy, surgical membranectomy, and penetrating keratoplasty (PKP) were done when necessary. Visual acuity was measured 1 week following intervention and at the last follow-up.
Results:
Congenital (17 eyes, 43.6%), developmental (11 eyes, 28.2%), and traumatic (11 eyes, 28.2%) cataract were the indications for surgery. Posterior capsule opacification (34 eyes, 87.2%), updrawn pupil (15 eyes, 38.5%), decentered IOL (13 eyes, 33.3%), and pupillary capture (12 eyes, 30.8%) were the major complications. An Nd:YAG capsulotomy was attempted in 19 eyes (48.7%). Surgical membranectomy was performed in 10 eyes (25.6%); PKP was performed in 2 eyes (5.1%) to treat pseudophakic bullous keratopathy. One eye had to be eviscerated because of uncontrolled endophthalmitis. In 31 eyes in which visual acuity could be measured, 27 had an acuity of 6/60 or worse at the time of presentation. Following intervention and amblyopia therapy, 19 eyes achieved a visual acuity of 6/18 or better.
Conclusion:
Routine ECCE with IOL implantation in pediatric eyes is associated with various problems and may lead to permanent visual disability.
