To evaluate short-term visual outcome, patient acceptance, and tolerance of mini-scleral contact lenses (SCLs) in the management of various corneal pathologies.
Retrospective case series.
Thirty-two patients (40 eyes) who received mini-SCLs.
Single-centre retrospective case series, between February 2010 and January 2013, of 32 patients (40 eyes) with various corneal pathologies who were offered either Maxim 5R, Maxim 7, or Maxim 7 × 11 mini-SCLs for nonsurgical optimization of visual correction. Patients were followed up at 1 and 3 months for assessment of best-corrected visual acuity, comfort, length of daily wear, and complications.
Thirty-two patients (40 eyes), with a mean age of 41 ± 16 years, opted to receive mini-SCLs. Eighteen patients had previously undergone surgery such as penetrating keratoplasty, deep anterior lamellar keratoplasty, and intraocular lens implantation. The median best-corrected visual acuity improved from 0.3 logMAR (range 0-1.3) before mini-SCLs, to 0.05 logMAR (range 0-1) with mini-SCLs (p < 0.0001). At 1-month follow-up, the median length of wear was 10 hours/day (range 1.5-15). At 3-month follow-up, the median length of wear was 12 hours/day (range 2-15). All eyes were comfortable at initial use of mini-SCLs and 91% were comfortable at 3-month follow-up.
Mini-SCLs may be a comfortable management option for patients with keratoconus and other corneal pathologies who are unable to achieve adequate visual outcome with traditional spectacles or rigid gas-permeable contact lenses.
评估微型巩膜接触镜（SCL）在治疗各种角膜病变时的短期视觉效果、患者接受度和耐受性。
回顾性病例系列。
32例接受微型SCL的患者（40只眼）。
单中心回顾性病例系列研究，在2010年2月至2013年1月期间，对32例（40只眼）患有各种角膜病变的患者提供Maxim 5R、Maxim 7或Maxim 7×11微型SCL，用于非手术优化视力矫正。患者在1个月和3个月时进行随访，评估最佳矫正视力、舒适度、每日佩戴时长及并发症。
32例患者（40只眼），平均年龄41±16岁，选择接受微型SCL。18例患者此前接受过穿透性角膜移植术、深板层角膜移植术和人工晶状体植入术等手术。最佳矫正视力中位数从佩戴微型SCL前的0.3 logMAR（范围0 - 1.3）提高到佩戴微型SCL后的0.05 logMAR（范围0 - 1）（p < 0.0001）。在1个月随访时，佩戴时长中位数为每天10小时（范围1.5 - 15小时）。在3个月随访时，佩戴时长中位数为每天12小时（范围2 - 15小时）。所有眼睛在初次使用微型SCL时均感觉舒适，在3个月随访时有91%感觉舒适。
对于圆锥角膜和其他角膜病变患者，若使用传统眼镜或硬性透气性接触镜无法获得足够的视觉效果，微型SCL可能是一种舒适的治疗选择。
