“…Local stretching of the iris with iris retractors led to the damage of rim pigment. Alternatively, different kinds of iris retracting devices with smooth dilation principle can be used (Malyugin ). But the application of iris expanders is limited in the youngest children due to the small size of their eyes (anterior chamber depth, white‐to‐white distance, etc.…”

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.

“…Patients with pupillary diameter above 5 mm were included in group 1, and those below 5 mm were included in group 2. The reference pupillary diameters for grouping were made according to the narrow and normal pupillary width specified in the referenced studies (17)(18)(19). Group Visual acuity, intraocular pressure and anterior chamber depths were evaluated in both groups before and after surgery.…”

A small pupil and poor pupil dilation are well-known risk factors faced by veterinary ophthalmologists during and after cataract surgery. We here describe two cases of phacoemulsification performed using an iris expander (Visitec I-Ring Pupil Expander, Beaver-Visitec International, USA) for treating cataracts in dogs with small pupils. Using this technique, we performed cataract extraction effectively in dogs with insufficiently dilated pupils. This case report provides useful information on the use of an iris expander for phacoemulsification in eyes with a small pupil, which can be applied in veterinary settings.
