Summary: Purpose: To measure the anterior segment using optical coherence tomography in children with primary IOL implantation following congenital and developmental cataract surgery.
Material and Methods: 96 eyes of 62 patients (39 boys, 23 girls) at the age from 3 to 17 years (mean 9.1±3.1) were examined. Mean age at surgery was 5.7 years (±3.7), mean follow-up 6.5 years (±2.2). Group I comprised 34 children with bilateral IOL, group II 28 patients with unilateral IOL, group IV – 16 children (surgery at the age below 2 years). Control group IIa – 28 unoperated eyes from group II, group III consisted of 44 eyes of 30 healthy children (14 girls, 16 boys) at the age from 4.5 to 15.5 years (mean 9.3±2.6). All study participants underwent optical coherence tomography with Visante 1000 OCT (Carl Zeiss). Central corneal thickness (CCT), anterior chamber depth (ACD), chamber angle-to-angle distance (CAAD), iridocorneal angle size (IAS) were measured. The results were analyzed statistically; p(α) = 0.05.
Results: The following mean values were calculated based on OCT measurements:
group I – CCT 542±91 µm, ACD 3.84±0.52 mm, CAAD 12.13±0,53 mm; IAS at the nasal and temporal positions were 31.5±6.5° and 28.9±5.0°, respectively,
group II – CCT 540±41 µm, ACD 3.72±0.54 mm, CAAD12.40±0.52 mm; IAS at the nasal and temporal positions were 33.9±9.2° and 31.9±8.5°, respectively,
group IV – CCT 530±25 µm, ACD 3.51±0.50 mm, CAAD 12.19±0.72 mm; IAS at the nasal and temporal positions were 32.5±6.0° and 29.9±6.8°, respectively,
control group IIa – CCT 536±36 µm, ACD 3.13±0.26 mm, CAAD 12.50±0.61 mm; IAS at the nasal and temporal positions were 31.8±6.0° and 29.8±6.4°, respectively,
control group III – CCT 544±31 µm, ACD 3.03±0.23 mm, CAAD 12.49±0.41 mm; IAS at the nasal and temporal positions were 30.0±6.7° and 29.6±6.7°, respectively.
Statistical analysis revealed statistically significant increase in anterior chamber depth in groups I and II. Chamber angle-to-angle distance was significantly greater in group II and the control. Mean values of the remaining parameters did not differ significantly between the groups.
Conclusion: The present investigation has not demonstrated any disadvantageous effects of artificial IOL implantation on the anterior segment, the development of which proceeds as in healthy children.
