Purpose: To evaluate the implantation of apodized diffractive multifocal intraocular lenses (IOLs) in children with unilateral cataract.
Setting: Ophthalmology Service, Hospital Clínico Lozano Blesa, Zaragoza, Spain.
Design: Prospective clinical study.
Methods: Five children between 4 and 6 years of age with unilateral cataract had cataract extraction and implantation of an apodized diffractive multifocal IOL (AcrySof Restor SN60D3). Phacoaspiration was accompanied by posterior capsulorhexis followed by an anterior vitrectomy. Uncorrected distance (UDVA), corrected distance (CDVA), and corrected near (CNVA) visual acuities; binocular function using the Worth 4-dot test and the TNO stereotest; and subjective symptoms such as glare and halos were evaluated over 21 months of follow-up.
Results: At the final follow-up visit, the mean UDVA was 0.45 ± 0.149 logMAR and the mean CDVA was 0.30 ± 0.06 logMAR with 20/32 in 3 eyes, 20/50 in 1 eye, and 20/63 in 1 eye. The mean CNVA was 0.10 ± 0.05 logMAR (about 20/25) with J1 in 2 eyes, J2 in 1 eye, J3 in 1 eye, and J4 in 1 eye. The stereoacuity was 120 seconds of arc (arcsec) in 2 patients, 240 arcsec in 1 patient, 1980 arcsec in 1 patient, and nonexistent in 1 patient. The Worth 4-dot test showed that 4 patients had fusion. None of the 5 patients complained about halos or glare. No IOL decentration was observed in any patient.
Conclusion: Implantation of an apodized multifocal IOL seems to be a satisfactory alternative to monofocal pseudophakia in children with unilateral cataract.

Prevalence of visually significant cataract and cataract surgical coverage in Indigenous and non-Indigenous Australians: a systematic review and meta-analysis.
BMJ Open Ophthalmol
January 2025
Lions Eye Institute, Nedlands, Western Australia, Australia.
Aims: Compare the prevalence of age-related cataract and the cataract surgical coverage rate between Indigenous and non-Indigenous Australians and explore differences in these estimates across location and time.
Methods: The Joanna Briggs Institute guidance for systematic reviews of prevalence studies was followed. A systematic search of Medline, Embase, Web of Science and grey literature from database inception to June 2022 was performed.
Comparison of Short-Term Clinical Outcomes After Implantation of Two Monofocal, Aspheric Intraocular Lenses.
Diagnostics (Basel)
December 2024
Department of Ophthalmology, Asan Medical Center, University of Ulsan College of Medicine, Seoul 05505, Republic of Korea.
Objectives: This study compared the visual outcomes and optical quality of two monofocal, aspheric intraocular lenses (IOLs; CT LUCIA 621P, Carl Zeiss Meditec; Eyhance ICB00, Johnson & Johnson Vision) by evaluating visual acuity, contrast sensitivity, and higher-order aberrations 1 month post-cataract surgery.
Methods: In this retrospective, comparative study, 120 eyes (72 patients) that underwent cataract surgery with either CT LUCIA 621P (Lucia group) or Eyhance ICB00 (Eyhance group) implantation (60 eyes/group) were retrospectively investigated. Visual acuity at various distances and defocus curves were measured 1 month postoperatively.
Early Patching Behaviors that Improve the Chances of Good Visual Acuity in Children Treated for Unilateral Congenital Cataract.
Ophthalmology
December 2024
Department of Ophthalmology, Stanford University, Palo Alto, CA.
Objective: Achieving near normal vision following unilateral congenital cataract surgery is possible but requires early surgery, optical correction and consistent patching. Patching is often challenging for children and their caregivers. The goal of these analyses is to examine the association between reported consistency in patching during the first year after surgery and visual acuity.

Objective: To evaluate the output of a child eye health programme in terms of identification, referral, and volume of paediatric cataract surgeries in Kaduna State, Nigeria.
Materials And Methods: This was a retrospective review of the North-West Nigeria Child Eye Health Initiative programme referral registers at primary, secondary and tertiary hospitals in Kaduna State. Theatre registers of children 0-16 years who had cataract surgery at National Eye Centre Kaduna between 2016 and 2019 were also reviewed.
Real-world use of integrated intraoperative OCT in pediatric cataract.

University of Pittsburgh Medical School, UPMC Children's Hospital of Pittsburgh, UPMC Vision Institute, Pittsburgh, USA.
Purpose: To study the utility of integrated intraoperative OCT (i2OCT) in pediatric patients with cataracts in the real world.
Methods: It was a retrospective case series. We included patients aged 0-12 years with unilateral or bilateral cataracts who underwent cataract surgery or membranectomy for visual axis opacification between July 2022 and December 2023, where intraoperative OCT was used.
