Contact lens intolerance in keratoconus may be due to the formation of a proud nebula at or near the apex of the cone that gives rise to contact lens related abrasions. These nebulae do not flatten when contact lens wear is discontinued. We describe a simple technique of superficial keratectomy to remove proud nebulae in which the resulting defect healed quickly under a therapeutic hydrogel lens. In all of the six cases described patients were able to resume contact lens wear within one month of the procedure. One case was lost to follow-up. Of the remaining five (follow-up 3-9 months), all achieved comfortable wearing times of 8 hours or more and visual acuities of 20/40 or better. One patient developed a recurrent epithelial defect that resolved on discontinuing lens wear for one week. Corneal transplantation was thus avoided.
圆锥角膜患者的隐形眼镜不耐受可能是由于在圆锥顶点或其附近形成了一个隆起的角膜云翳，从而导致与隐形眼镜相关的擦伤。当停止佩戴隐形眼镜时，这些角膜云翳不会变平。我们描述了一种简单的浅表角膜切除术技术，用于切除隆起的角膜云翳，在治疗性水凝胶镜片下，由此产生的缺损愈合迅速。在所描述的6例患者中，所有患者在手术后1个月内都能够恢复佩戴隐形眼镜。1例失访。其余5例（随访3 - 9个月），所有患者的舒适佩戴时间均达到8小时或更长，视力达到20/40或更好。1例患者出现复发性上皮缺损，在停止佩戴镜片1周后痊愈。从而避免了角膜移植。
