RESUMO
To evaluate the vitreoretinal complications in myopes after Visian implantable collamer lenses [ICL] implantation. This is a retrospective, observational, non-comparative clinical study that evaluated 617 consecutive myopes who underwent ICL implantation at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen between July 2006 and May 2010. Follow up ranged from 6 months to 40 months. Preoperative and postoperative patient evaluation included manifest and cycloplegic refractions, uncorrected [UCVA] and best spectacle-corrected visual acuity [BSCVA], slit-lamp biomicroscopy, intraocular pressure and dilated retinal examination. Investigations included corneal topography, central corneal thickness, anterior chamber depth and white to white diameter. Retinal diseases and complications were recorded and analyzed preoperatively and postoperatively. Preoperatively, 61 [9.9%] eyes had posterior segment pathology requiring prophylactic laser photocoagulation. One eye developed spontaneous rhegmatogenous retinal detachment [RRD], one eye developed traumatic retinal detachment and two eyes required laser treatment postoperatively. The overall retinal detachment rate post-ICL was 0.32%. Posterior segment complications are rare after ICL implantation but dilated vitreoretinal assessment is important before and after the procedure. Patients with suspicious retinal lesions need a comprehensive vitreoretinal evaluation by a retinal specialist. If a patient develops floaters or blurry vision he/she requires further assessment by a vitreoretinal specialist
