Background: In congenital and developmental cataract primary undercorrection of intraocular lens (IOL) power is a common practice. However, long-term refractive status of these children is largely unknown. Aims and Objective: To analyse refractive status after cataract surgery with undercorrected IOL power implantation in congenital and developmental cataract. Materials and Methods: This study was descriptive, retrospective conducted for three years from 1st January 2013 to 31st December 2015. The children (> 6 months to <=7 years of age) who underwent cataract surgery for congenital and developmental cataract with a primary IOL implantation and had reached the age of 8 years were studied. The data were collected in terms of demography, axial length, biometry, IOL implanted, hyperopic correction and postoperative refractive status at 8 years. Results: Total numbers of children operated were 181 with total eyes 288. Unilateral cases were 74 (40.88%) and bilateral 107 (59.12%). ...
Unilateral intraocular lens implantation during the first six months of life
Journal of American Association for Pediatric Ophthalmology and Strabismus, 1999
The purpose of this study was to determine the incidence of postoperative complications and the occurrence of myopic shift in infantile eyes after cataract surgery and implantation of an intraocular lens (IOL). Methods: Cataract surgery and IOL implantation was performed on 11 infants with unilateral congenital cataracts who had a mean age of 10 ± 6 weeks at 5 clinical centers. IOLs with a mean power of 26.2 ± 2.3 D were implanted using a standardized protocol. The infants were then followed up for a mean of 13 ± 6 months for postoperative complications and longitudinal changes in their refractive error. Results: Eight of the 11 eyes had postoperative complications and were treated with a reoperation. Complications included open-angle glaucoma (n = 2), lens reproliferation into the visual axis (n = 2), pupillary membranes (n = 2), and corectopia (n = 2). A younger age at the time of surgery was positively correlated with the development of a postoperative complication requiring a reoperation (P = .03). A mean myopic shift of 5.49 D occurred in these eyes a year after surgery. No preoperative factors could be identified that correlated with the magnitude of the myopic shift. Conclusion: IOL implantation during infancy is associated with a high complication rate frequently requiring reoperation. A large myopic shift typically occurs that necessitates an initial or a late overcorrection with spectacles or a contact lens, depending on the power of the IOL implanted. Until ongoing randomized trials are completed, we recommend that surgeons exercise caution before implanting IOLs in the eyes of infants. (J AAPOS 1999;3:344-9)

The optimal role of intraocular lenses (IOLs) in infants remains a controversial topic for many reasons, including concerns about significant complications occurring in young rapidly developing eyes. Methods: To assess the number and type of significant complications requiring further intervention occurring in the first postoperative year, we reviewed the records of 15 eyes of 13 infants undergoing lensectomy with posterior chamber IOL and pars plana vitrectomy (PPV)/capsulectomy under 6 months (group A) of age as part of an ongoing prospective study of IOL use in infants. This group was compared with a group of 16 children age 10 months to 5 years undergoing an identical procedure (group B) and a group of 33 infants less than 6 months of age undergoing lensectomy/vitrectomy without IOL (group C). Results: Thirteen of 15 eyes in group A required additional surgery in the first postoperative year. Twelve of the 15 eyes (80%) developed secondary opacification across the visual axis posterior to the IOL requiring a second PPV and one eye developed pseudophakic glaucoma. Two patients required a third PPV to keep the visual axis clear. In group B, 0 of 16 (P Ͻ .0001) developed secondary opacification of the visual axis. In group C, 4 of 33 (12%; P Ͻ .0001) developed pupillary opacification in the first postoperative year. Conclusions: Intraocular lens implants in infants may be associated with a higher complication rate requiring further surgery during the first postoperative year than is lensectomy/vitrectomy surgery without IOL implant in infants or lensectomy/IOL/vitrectomy surgery in children older than 6 months of age.

Update of intraocular lens implantation in children
Saudi Journal of Ophthalmology, 2012
Cataract is a common problem that affects the vision in children and a major cause of amblyopia in children. However, the management of childhood cataract is tenuous and requires special considerations especially with regard to intraocular lens (IOL) implantation. Age at which an IOL can be implanted is a controversial issue. Implanting an IOL in very young children carries the risk of severe postoperative inflammation and posterior capsule opacification that may need other surgeries and may affect the vision permanently. Accuracy of the calculated IOL power is affected by the short eyes and the steep keratometric values at this age. Furthermore, choosing an appropriate IOL power is not a straight forward decision as future growth of the eye affects the axial length and keratometry readings which may result in an unexpected refractive error as children age. The aim of this review is to cover these issues regarding IOL implantation in children; indications, timing of implantation, types of IOLs, site of implantation and the power calculations.
