“…Enlargement of the incision to 2.4 mm prior to implantation of the IOL has now become a standard. With this technique, implantation of a foldable Type 89A or 89F IOL with optic size 5.0 mm and dioptres ranging from 8 D to 36.5 D was possible in all subsequent cases (Lytvynchuk et al 2019).…”

Purpose To report the rate and management of intra‐ and early postoperative complications of bag‐in‐the‐lens intraocular lens (IOL) implantation technique for cataract treatment in paediatric patients of different age groups. Settings Department of Ophthalmology, Justus‐Liebig‐University Giessen, University Hospital Giessen and Marburg GmbH, Campus Giessen, Giessen, Germany. Design Retrospective non‐randomized consecutive case series. Methods Ninety eyes of 60 paediatric cataract patients were enrolled to this retrospective non‐randomized observational consecutive case series single‐centre study. All patients underwent cataract surgery with bag‐in‐the‐lens IOL implantation between January 2008 and December 2018, performed by two experienced surgeons. The entire cohort was divided into four age groups: first – 0–<3 months, second – 3–<12 months, third – 12–<36 and fourth – >36 months–17 years of age. The intra‐ and postoperative complications were based on the clinical records. The description of management of complications related specifically to bag‐in‐the‐lens IOL technique was based on the 39 consecutive cases operated since 1 Jan 2016 by one single surgeon that were all video documented. The early postoperative period was defined as 12 months after surgery. Results Overall, there were 27 unilateral and 33 bilateral surgical cases of 24 female and 36 male children. The mean age at surgery was 45.25 months (range 1–200 months). The most common intraoperative events were vitreous prolapse and anterior capsule rupture with 28.9% and 13.3%, respectively. Within 12 months of follow‐up, five eyes (5.6%) were re‐operated because of visual axis reo‐pacification (VAR). Intraocular hypertension was diagnosed in seven eyes (7.8%), including two cases that required surgical treatment. In all cases with intra‐ and early postoperative complications related specifically to bag‐in‐the‐lens technique, it was possible to manage them and successfully implant bag‐in‐the‐lens IOL. Conclusions Implementation of bag‐in‐the‐lens technique in the treatment of paediatric cataract was associated with a relatively low rate of intra‐ and postoperative complications, including rare cases of VAR. The correct management of complications related specifically to bag‐in‐the‐lens IOL implantation technique shall to be considered during the learning curve.

“…While for patients older than 2, the Haigis formula performed better. The possible reason is that the Haigis formula can predict better the effective position of IOL, although it may need further study, and the a1 constant of the Haigis formula is tied to the measured ACD, which can be an issue in children of different eye dimensions [ 22 ]. The Holladay 2 formula needs ACD as well as lens thickness for calculation, while lens thickness may vary due to lens abnormality such as posterior capsular defect [ 23 ].…”

Purpose. This study aims to compare the accuracy of five intraocular lens (IOL) power calculation formulas (SRK/T, Hoffer Q, Holladay 1, Haigis, and Holladay 2) for pediatric eyes in children of different ages. Methods. In this prospective study, patients who received cataract surgery and IOL implantation in the capsular bag were enrolled. We compared the calculation accuracy of 5 formulas at 1 month postoperatively and performed subgroup analysis with the patients divided into three groups according to their ages at the time of surgery as follows: group 1 (age ≤ 2 years, 35 eyes), group 2 (2 years < age < 5 years, 38 eyes), and group 3 (age > 5 years, 29 eyes). Results. 75 patients (102 eyes) were enrolled in this study. The Haigis formula got the smallest PE among all formulas in all three groups. With regard to APE, there were no statistical differences among the formulas except group 2, with the SRK/T formula a little smaller, the Holladay 2 formula a little larger in group 1, and the Haigis formula a little smaller in group 3. In group 2, the Haigis formula had the lowest APE (0.87 ± 0.61 D), while the Holladay 2 formula had the largest (1.71 ± 1.20 D, p<0.001), followed by the Holladay 1 formula (1.51 ± 1.07 D, p=0.002). On comparing the percentage of APE within 0.5 D and 1.0 D obtained with 5 formulas in each group, there were no statistical differences. The SRK/T formula and the Holladay 1 formula showed the highest percentage (40.00% and 60.00%) in group 1. While the Haigis formula got the highest percentage in less than 0.5 D (34.21%) and less than 1 D (60.53%) in group 2. In group 3, the Holladay 2 formula and the Haigis formula got the highest percentage less than 0.5 D (58.62%) and less than 1 D (79.31%). The multiple linear regression indicated that the age at the time of surgery was a significant factor affecting the accuracy of APE; after removing the age, AL was the only factor that affected the accuracy of APE. Conclusion. The SRK/T and the Holladay 1 formulas were relatively accurate in patients younger than 2 years old, while the Haigis formula performed better in patients older than 2.
