Insights
Silicone elastomer lenses (Silsoft) are safe and effective for pediatric aphakia management, offering good optical correction. However, availability and replacement costs present challenges in certain socioeconomic settings.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Contact Lens Technology
Background:
- Pediatric aphakia requires effective optical correction post-surgery.
- Silicone elastomer lenses offer a potential solution for visual rehabilitation in children.
Purpose of the Study:
- To evaluate the performance of silicone elastomer lenses (Silsoft) in pediatric aphakia.
- Assess the safety, fit, and wearability of these lenses in young patients.
Main Methods:
- Retrospective study of pediatric aphakic eyes fitted with Silsoft lenses.
- Analysis of lens fit, wear duration, adverse events, and replacement reasons.
Main Results:
- Satisfactory fit achieved in 81.1% of 106 eyes across 74 children.
- One-week extended wear was common; 64.2% wore lenses for ≥6 months.
- Lens replacement was frequent; 75.5% probability of no complications at 24 months.
Conclusions:
- Silsoft lenses are safe and provide satisfactory optical correction for pediatric aphakia.
- Ease of handling is a noted advantage.
- Limited availability and high replacement costs are significant limitations.
Purpose:
To evaluate the performance of silicone elastomer lenses in pediatric eyes with aphakia.
Methods:
We retrospectively studied pediatric aphakic eyes fit with Silsoft lenses (elastofilcon A, Bausch & Lomb) at the L.V. Prasad Eye Institute, India.
Results:
Seventy-four children (106 eyes) with a median age of 9.0 months (range: 1 month to 12 years) were included in the study. Congenital cataract was the pre-existing pathology in 84 eyes. Lenses were fit between 1 week and 5 years following surgical intervention (median: 25 days). The most frequently used base curves were 7.5 mm (n=46 eyes) and 7.7 mm (n=39 eyes); lens diameter was 11.3 mm (n=103 eyes). Satisfactory fit was achieved in 86 eyes (81.1%). One-week extended wear was the most commonly recommended mode of wear (n=95 eyes). Lenses (n=118) were replaced for change of power, lens loss, and deposits or damage. Lenses were worn for > or =6 months in 68 eyes (64.2%). Twenty-three contact lens related adverse events occurred, all of which resolved uneventfully. On survival analysis, the probability of not having a lens related complication was 75.5% (95% CI; 61.5-89.5) at 24 months.
Conclusions:
In the management of pediatric aphakia, Silsoft lenses are safe, provide satisfactory optical correction, and are easy to handle. Limited availability and the financial costs associated with frequent lens replacement are limitations in our socioeconomic circumstances.
