To report a case of Implantable Collamar Lens (ICL) decentration and to discuss the importance of ICL size calculation
Ophthalmology Department Habib Thameur hospital Tunis, TUNISIA
A 29-year-old patient with bilateral high myopia. He underwent a refractive surgery (LASIK) in his right eye and ICL implantation in his left eye. Icl power calculation was performed using the modified vertex formula provided by the manufacturer. Postoperative anterior segment optical coherence tomography (AS-OCT) showed a low vault (172 μm). We decided on a close follow-up with monitoring of the vault size but the patient disappeared and returned 8 months later complaining of blurred and decreased vision. His visual acuity was 20/100, the anterior segment was normal and the intraocular pressure was 12(A). SA-OCT revealed a vault of 84 μm and specular microscopy showed a decrease in the number of endothelial cells. The patient underwent emergency surgery associating ICL explantation, phacoemulsification and monofocal IOL implantation.
ICL implantation is a safe and effective refractive surgery but an accurate ICL size calculation is mandatory to predict postoperative vault height. Up to the present, the prediction of vault and ICL sizing remains technically problematic.
