Insights
Predicting myopic shift after intraocular lens (IOL) implantation in children remains challenging. This study found no significant difference in refractive changes between primary and secondary IOL implantations, with the lowest shift observed in the youngest children.
Area of Science:
- Ophthalmology
- Pediatric ophthalmology
- Refractive surgery
Context:
- Children undergoing cataract extraction and intraocular lens (IOL) implantation can experience a myopic shift.
- The extent of this refractive change is difficult to predict accurately.
- This study investigates refractive development in pseudophakic children following both primary and secondary IOL implantation.
Purpose:
- To report and analyze the refractive development in pseudophakic children after primary and secondary IOL implantation.
- To compare refractive changes between primary and secondary IOL implantations across different age groups.
- To assess the predictability of myopic shift in pediatric patients.
Summary:
- A retrospective review of 62 eyes from 41 patients (aged 3-12 years) who received IOL implantation between 2000 and 2008 was conducted.
- The mean myopic shift was 2.5 D overall, with no significant difference between primary and secondary IOL implantations.
- The lowest myopic shift was observed in the youngest age group (3-4 years), contrary to some existing literature.
Impact:
- Findings suggest that primary and secondary IOL implantations result in similar refractive changes in children.
- The study highlights the difficulty in precisely predicting myopic shift after pediatric IOL surgery.
- Results provide valuable data for ophthalmologists managing pediatric pseudophakia and counseling families on visual outcomes.
Background:
A so-called myopic shift after cataract extraction and IOL implantation is known to occur in children. How much is difficult to predict. In this study we report the refractive development in pseudophakic children after primary and secondary IOL implantation.
Methods:
The refractive change in all patients receiving an IOL-implantation between 2000 and 2008 with a follow-up of a minimum of 6 months was reviewed (6 - 107 months). Rigid or foldable lenses were implanted by the same technique. Refraction postoperatively and at last follow-up was measured. 62 eyes of 41 patients were reviewed. Patients were divided into three groups based on age at time of surgery: 3 - 4 years, 5 - 6 years and 7 - 12 years.
Results:
The mean myopic shift was 2.5 D in both study groups, patients with primary and secondary IOL implantation. In the group with 3 - 4-year-old children mean myopic shift was 1.5 D in primary and 1.0 D in secondary implantations, in the group with 5 - 6-year-old children 2.75 D in primary and 3.25 D in secondary implantations and in the group with 7 - 12-year-old children 2.0 D in both primary and secondary implanted IOLs.
Conclusions:
We have shown that there are no differences in refractive changes between primary and secondary IOL implantations in our study group. In contrast to other findings we found the lowest myopic shift in the group of 3 - 4-year-old patients. Our results show that a prediction of expected myopic shift in children after IOL implantations remains difficult.
