Nine Years' Follow-up of Bilateral Extremely Low Vaulting of Implantable Collamer Lens: Case Report

Abstract

Purpose: To present a patient with bilateral implantable Collamer lens (ICL) implantation with extremely low vault who was followed up over 9 years and in whom no cataract was detected. Methods: A 56-year-old woman underwent uneventful bilateral ICL implantation and her postoperative ICL vaulting was 10 and 8 µm in the right and left eye, respectively. After consultation with the patient, it was decided to withhold surgical intervention and follow up closely. Results: Nine years postoperatively, the patient had normal ophthalmological examination results: uncorrected distance and near visual acuity of 20/20, normal intraocular pressure and open angle, stable ICL with low vaulting of 8 to 12 µm, clear lens with stable Objective Scatter Index scores, and normal posterior segment. Conclusions: This case report shows that even though low ICL vault is a risk factor for cataract development, withholding surgical intervention should be considered depending on the patient's age, characteristics, and compliance with close follow-up.
