Toric Intraocular Lens Implantation in Pediatric Cataract

A Prospective Randomized Controlled Trial of Toric Intraocular Lens Implantation in Pediatric Cataractous Eyes

To evaluate the visual and refractive outcomes after an intraocular lens (IOL) implantation in pediatric eyes with cataract and preexisting corneal astigmatism

This single-center, single-blinded, prospective, randomized controlled trial was performed at two sites of Kazakh Eye Research Institute.

Children with pediatric cataract and corneal astigmatism were included and randomized to two groups for pediatric cataract surgery with toric and non-toric intraocular lens (IOL) implantation. The uncorrected and corrected distance visual acuity, near visual acuity, keratometry data, and residual astigmatism were evaluated.

The purpose of this study is to evaluate the visual and refractive outcomes after a toric IOL implantation in pediatric eyes with cataract and preexisting corneal astigmatism.

Inclusion criteria:

1. Visually significant cataract;
2. Corneal astigmatism more than 1.25 diopters;
3. Children aged ≥ 6 years and < 18 years.

Exclusion criteria:

1. Patients with a corneal diameter less than 9 mm;
2. Presence of corneal scarring;
3. Irregular astigmatism;
4. Intraocular pressure more than 25 mm Hg;
5. Active inflammatory process of the eyeball or signs of a previous episode of inflammation;
6. Traumatic, subluxated, or complicated cataract;
7. Persistent Fetal Vasculature;
8. Diseases of the optic nerve or macula that may limit visual potential;
9. History of previous intraocular surgeries;
10. Performing posterior capsulorhexis intraoperatively.
