Refractive outcomes with secondary intraocular lens implantation in children

Secondary intraocular lens implantation after pediatric aphakia

“…Our absolute mean PE was 0.9 AE 0.9. Moore and colleagues 16 found mean absolute PE to be 1.64 D AE 1.58 D. They found no significant associations between mean absolute PE and other variables, such as axial length, mean keratometry, bag versus sulcus, formulae used, and age at primary and secondary surgery (P . 0.05).…”

Refractive outcomes and prediction error following secondary intraocular lens implantation in children: a decade-long analysis

“…The mean absolute value of PE at 3 months observed in the present study, albeit slightly higher, was comparable to that reported in limited number of previous paediatric secondary IOL series (table 2). 9 18 Moore et al 9 calculated the PE between 6 and 8 weeks whereas Nihalani and Vanderveen4 did the same between 4 and 8 weeks postoperatively. In the current study 20% had an absolute PE within 0.5 D and 60% within 2 D. In a study of 61 eyes with secondary ciliary sulcus-fixated IOL implantation, Awad et al 6 found that 78% of the patients had a postoperative refraction ±2 D of the predicted value.…”

“…Recent studies have reported on the safety and favourable visual outcomes with secondary IOL implantation 4–10. However, studies on refractive outcomes and prediction error (PE) following secondary IOL implantation in children have been limited 4 6 9 10…”

Comparison of aphakic refraction formulas for secondary in-the-bag intraocular lens power estimation in children

“…1 Aphakic children may not be cooperative for measurements of axial length (AL) and keratometry (K), and these measurements may not be available in the operating room. In 2004 Hug 2 described a formula that uses preoperative aphakic refraction (AR) to calculate the IOL power to be implanted.…”
