作者报告2例因戴角膜接触镜引起的角膜内出血。例1:女,70岁,左眼行白内障囊内摘出术,术后戴常戴型软性角膜接触镜,11年后,该眼颞下方角膜基质层出血,并向中央区扩散,视力降至20/400,数月内部分吸收。再戴原接触镜再加矫正眼镜,视力矫正至20/50,伴有黄斑变性。4年后因左眼疼痛再诊,视力20/300,在原出血部位又有出血,见角膜浅层及深层新生血管形成。停戴接触镜后,出血少量吸收,视力低于20/200,遂施行穿透性角膜移植和
The authors report 2 cases of corneal hemorrhage due to wearing contact lenses. Example 1: Female, 70 years old, left cataract extraction of intracapsular cataract surgery, wearing a soft wearing contact lens after surgery, 11 years later, the corneal epithelial hemorrhage under the temporal cornea, and spread to the central area, decreased visual acuity To 20/400, absorbed within a few months. Then wear the original contact lens plus corrective glasses, vision correction to 20/50, associated with macular degeneration. 4 years after the left eye pain re-diagnosis, visual acuity 20/300, there are bleeding in the original bleeding site, see the corneal shallow and deep neovascularization. Stop wearing contact lenses, a small amount of bleeding, visual acuity less than 20/200, then the implementation of penetrating keratoplasty and
