Description
Summary:To evaluate the safety and effectiveness of the Visian Implantable Collamer Lens (ICL) implantation in high myopic patients with inactive Graves' ophthalmopathy (GO) by observing the changes of choroidal thickness (CT). Eight patients (16 eyes) with high myopia accompanied with inactive GO were selected as the experimental group (group A) and 18 high myopic patients (36 eyes) without GO were selected as a control group (group B). The outcomes of uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BCVA), safety index, efficacy index, intraocular pressure (IOP), vault, corneal endothelial count, and choroidal thickness (CT) were observed. The values of CT were measured using swept-source optical coherence tomography (SS-OCT) scans. The UCVA and BCVA in all operated eyes were better than that before surgery. The postoperative safety index and efficacy index were 1.23 and 1.19 in the group A, respectively, and 1.26 and 1.21 in the group B, respectively. In both groups, foveal CT increased significantly in high myopic patients at 2 h and at 3 months after surgery, compared to preoperative values. The same tendencies were observed in the inner nasal and outer nasal regions. Compared with patients without GO, the increase of CT was more obvious in GO patients, 2 h postoperatively (P = 0.006) and 3 months postoperatively (P = 0.011). The ICL implantation is safe and effective in high myopic patients with inactive GO. Subfoveal and nasal CT may be useful parameters for monitoring the activity of GO patients.
