Bilateral implantation of a non-diffractive extended depth of focus intraocular lens in a pediatric patient with lamellar cataract.

Abstract

Purpose: To present a case of a pediatric patient with infantile cataract, which was treated with lens extraction surgery and bilateral implantation of an extended depth of focus (EDOF) intraocular lens (IOL).

Methods: A 13-year-old boy with bilateral lamellar cataract underwent standard phacoemulsification and bilateral implantation of a toric, non-diffractive EDOF IOL. Preoperative assessment included biometry, keratometry, and visual acuity testing. Postoperative follow-up included refraction, defocus curve, contrast sensitivity, and patient-reported outcomes.

Results: After a follow-up of three months uncorrected and corrected distance visual acuity on both eyes was 0.1 logMAR. Uncorrected intermediate visual acuity (80 cm) was 0.2 logMAR (left eye) and 0.1 logMAR (right eye), while uncorrected near visual acuity (40 cm) was 0.5 logMAR (left eye) and 0.4 logMAR (right eye). The contrast sensitivity using Pelli Robson charts shows good results of 1.85 for both eyes. The patient indicated very low values concerning optical phenomena and was very satisfied. The patient reported that he occasionally uses reading glasses in close proximity.

Conclusions: Bilateral implantation of a non-diffractive EDoF IOL resulted in high patient satisfaction with spectacle independence for distance and intermediate vision with an insignificant level of photic phenomena. The EDOF IOL appears to be a viable option for older pediatric patients undergoing cataract surgery.
