Abstract Details

Purpose:

Analysis of the results of surgical treatment of children with congenital cataract (CC) and corneal astigmatism (CA) with toric (TIOL), spherical and aspheric IOLs implantation.

Setting:

109147, Moscow, Marksistskaya str. 3/1, Excimer Eye Centre, kpershin@mail.ru

Methods:

The analysis included 93 children (123 eyes) with CC and CA. The observation period ranged from 0.4 to 9 years (4,3±0,8) .All the studied cases were divided into 3 groups. Group I (24 patients, 36 eyes) - cases of TIOL implantation with a combination of CC and CA. Group II (37 patients, 45 eyes) consisted of patients who with spherical and aspheric IOLs for the correction of the CC and CA. In group III (comparison) there were 32 patients (42 eyes) with CC, but without CA (including cases of physiological astigmatism less than 1.0 D) with spherical and aspheric IOLs.

Results:

. In the long-term follow-up in Group I we achieved a significant reduction in the cylindrical component of refraction as compared to groups II and III (p = 0,003 and 0,014, respectively). Thus, in the group I value of cylindrical refraction component was -0.28 diopter, while in group II -2,01 diopters, and in the group III -0,89 diopters which can be attributed to development of SIA in group III. UCVA and BCVA in group I are above than in group II and III, but a high significance of differences is not shown.

Conclusions:

In children after surgical treatment of CC, combined with CA greater than 1.25 D in the value of long-term follow cylindrical refraction component with was -0.28 diopters in TIOL group, which is significantly less compared with other groups. Visual acuity in the group with TIOL is higher than in the groups with aspherical and spherical IOLs, however, statistically significant differences are not shown.
