To report a case of bilateral implantable collamer lens (EVO-ICL) implantation for residual error of a patient after congenital cataract surgery.

A retrospective case report.

A 17-year-old boy had uneventful bilateral congenital cataract surgery 15 years ago. He came for the correction of his myopia. His BCVA was 20/20 with a manifest refraction of –6.00DS – 2.50DC *5 (OD) and –6.75DS – 3.25DC *180 (OS). A slit-lamp examination showed localized posterior iris synechiae of the left eye. Both the IOLs were in the capsular bag, but slightly dislocated to the naso-inferior. The anterior chamber depth was 3.27mm(OD) and 3.40mm(OS). The white-to-white was 11.5mm (OD) and 11.7mm (OS) on Pentacam and 11.7mm (OD) and 12.1mm (OS) on IOL Master. The angle-to-angle was 11.45mm (OD)and 11.41mm (OS) horizontally and 11.93mm (OD)and 11.97mm (OS) vertically on anterior-segment OCT. The endothelium count was within normal limit for both eyes. Based on the patient’s need, the target refraction was -1.24D and -1.43D for the right and left eye, respectively. Therefore, it was decided to proceed with implantation of a -8.50D/+2.50D TICL for the right eye and -9.50DS/+3.50D TICL for the left eye in the sulcus with vertical position (132 EVO). 

During the surgery, the posterior iris synechiae was completely released and then ICL was implanted into the sulcus. The post-operative UDVA was 20/20 (OD) and 20/25 (OS), with the manifest refraction of -0.50DS – 0.25DC*60 (OD) and -1.00DS (OS). The vault was 1223μm and 960μm 1 week post-operatively. The patient was followed for 6 months. The vision, IOP and examinations for the anterior and posterior segment were stable.

1. ICL implantation may be an alternative to currently available methods in managing residual error after congenital cataract surgery.

2. The size of ICL should be considered carefully based on the examinations pre-operatively.
