To describe the use of rigid gas-permeable scleral contact lenses (ScCL) in the treatment and visual rehabilitation of patients with medically controlled advanced atopic keratoconjunctivitis (AKC).
Retrospective chart review of 10 eyes with medically controlled advanced AKC whose treatment included the use of ScCL for protection of the cornea from the ocular surface environment and visual rehabilitation. Outcomes measured were changes in biomicroscopic findings and visual acuity.
Median follow-up period after ScCL fitting was 20.5 months (range, 14-32 months). An improvement in conjunctival hyperemia and corneal epithelial defects was observed in all eyes. Median best-corrected visual acuity before ScCL was logMAR 0.651 (Snellen 20/90; range, 20/45-20/400). After proper ScCL fitting, median logMAR visual acuity was 0.239 (Snellen 20/35; range, 20/20-20/50; P = 0.001). All patients gained at least 1 line of vision after initiation of ScCL, and 9 of 10 eyes experienced an improvement of at least 2 lines of vision. ScCL use was well tolerated by all patients, and no complications or infections occurred as a result of ScCL wear.
Rigid gas-permeable ScCL are useful and safe to use in the management of the ocular surface and in the visual rehabilitation of eyes with medically controlled advanced AKC.
描述硬性透气性巩膜接触镜（ScCL）在医学控制的重度特应性角结膜炎（AKC）患者治疗及视觉康复中的应用。
对10只患有医学控制的重度AKC眼睛进行回顾性病历审查，其治疗包括使用ScCL来保护角膜免受眼表环境影响及进行视觉康复。测量的结果为生物显微镜检查结果和视力的变化。
ScCL验配后的中位随访期为20.5个月（范围14 - 32个月）。所有眼睛的结膜充血和角膜上皮缺损均有改善。ScCL验配前的最佳矫正视力中位数为LogMAR 0.651（Snellen 20/90；范围20/45 - 20/400）。在正确验配ScCL后，LogMAR视力中位数为0.239（Snellen 20/35；范围20/20 - 20/50；P = 0.001）。所有患者在开始使用ScCL后至少提高了1行视力，10只眼中有9只眼视力至少提高了2行。所有患者对ScCL的使用耐受性良好，佩戴ScCL未出现并发症或感染。
硬性透气性ScCL在医学控制的重度AKC患者的眼表管理和视觉康复中使用是有用且安全的。
