Scleral contact lenses are increasingly becoming accepted as the method of choice for visual correction of the irregular cornea. As such, cases have surfaced which demonstrate complications arising from mini-scleral lenses. Identification of these issues and adjusting fitting techniques accordingly is necessary for reducing the risks associated with mini-scleral lens wear.
A 58 year old Caucasian female was referred for rigid gas permeable contact lens fitting for correction of right irregular astigmatism post penetrating keratoplasty. After four months of successful mini-scleral contact lens wear, the patient experienced a graft rejection episode and treated accordingly, then refit with a new mini-scleral lens. Five months after the lens refit, the patient presented with complaints of hazy vision, and a diagnosis of lens-induced corneal oedema made.
Increased awareness of the potential complications of mini-scleral lenses is necessary to encourage and enforce mini-scleral lens fitting techniques that meet the requirements of minimum vault but adequate protection of the compromised cornea.
巩膜接触镜越来越被视为矫正不规则角膜的视觉矫正的首选方法。因此，出现了一些由于微型巩膜镜片引起的并发症的病例。识别这些问题并相应地调整适配技术对于降低与微型巩膜镜片佩戴相关的风险是必要的。
一名 58 岁的白种女性因右眼穿透性角膜移植术后不规则散光，被转诊接受硬性透气性隐形眼镜矫正。成功佩戴微型巩膜接触镜四个月后，患者出现移植物排斥反应，并进行了相应的治疗，然后重新佩戴新的微型巩膜镜片。镜片重新配五个月后，患者出现视力模糊的症状，并诊断为镜片诱导性角膜水肿。
有必要提高对微型巩膜镜片潜在并发症的认识，以鼓励和实施符合最小拱高要求但能充分保护受损角膜的微型巩膜镜片适配技术。
