Intraocular lens implantation as an isolated risk factor for secondary glaucoma in pediatric patients.

OBJECTIVE

To evaluate the effect of intraocular lens (IOL) implantation on the development of secondary glaucoma after cataract surgery in pediatric patients.

DESIGN

Retrospective case series study.

METHODS

This study reviewed the medical records of children under 16 years of age who had undergone cataract surgery from 1996 to 2016 for congenital or developmental cataract. In every child an IOL was implanted in the primary surgery. Data collected included demographic information, age at cataract diagnosis and at surgery, surgical procedure, and postoperative follow-up of refraction, cup-to-disc ratio (C/D), intraocular pressure (IOP), and associated systemic and ocular anomalies. Patients with risk factors for glaucoma were excluded from the study.

RESULTS

Of the 255 children below age 16 years who underwent cataract extraction surgery with primary IOL implantation, 73 (124 eyes) met the inclusion criteria. Follow-up ranged from 4 to 18 years. Only 1 patient (0.8% of the 124 eyes) developed glaucoma in 1 of his 2 operated eyes; the surgeries were performed at 10 months, 1 week apart, and glaucoma was diagnosed 4 months later. One patient had suspected glaucoma in both eyes (incidence of 1.6%). Both these children were of Bedouin origin.

CONCLUSION

IOL implantation, by itself, is not a risk factor for development of secondary glaucoma after cataract surgery in a population below 16 years of age.
