A 56-year-old man presented with symptoms of monocular diplopia and reduced vision in his left eye. Visual acuities were R6/6, L6/12. At his previous visit left visual acuity was 6/6. An irregular area of anterior corneal stromal scarring was evident, encroaching on the visual axis of the left eye. Rigid lens fitting improved left visual acuity to 6/6, however, lens wear caused a corneal abrasion over the lesion after one to two hours of wear. Several other contact lens and surgical strategies were employed to successfully address the visual requirements of the patient.
一名56岁男性出现单眼复视和左眼视力下降的症状。视力检查结果为:右眼6/6,左眼6/12。他上次就诊时左眼视力为6/6。可见角膜前基质有不规则瘢痕区域,侵犯了左眼视轴。硬性镜片矫正使左眼视力提高到6/6,然而,佩戴镜片1至2小时后,病变处角膜出现擦伤。还采用了其他几种隐形眼镜和手术策略,成功满足了患者的视力需求。
