To determine the efficacy of the KeraSoft(®) IC (KIC) (Ultravision International Limited, Bedfordshire, UK), a silicone hydrogel contact lens, for the optical management of non-surgical corneal ectasias and to compare it with the Rose-K 2 RGP contact lens.
In a retrospective study ninety-four eyes fitted with KIC (group A) were compared with seventy-seven eyes fitted with Rose-K(®) RGP lenses as a control group. Ocular diagnoses, corneal curvature by topography, refraction, best spectacle-corrected visual acuity (BSCVA), and age at time of fitting were noted. Outcome data included average daily wearing time, contact lens complications, visual acuity with the lens (BCLCVA), power of the lenses and length of follow-up.
Differences in either BCLCVA or wearing time could not be statistically established (p = 0.63, p = 0.15) between both groups. More biomicroscopic complications were found in the RGP group, basically corneal staining (P < 0.0001). In the KIC group, BCLCVA was statistically similar between types of ectasia (p = 0.19) as well as in mild and moderate keratoconus (p = 0.45).
KIC is a good alternative for the optical management of irregular corneal astigmatism in non surgical corneal ectasias such as keratoconus and pellucid marginal degeneration.
评估 KeraSoft（®）IC（KIC）（英国贝德福德郡 Ultravision International Limited 公司），一种硅水凝胶隐形眼镜，在非手术性角膜扩张症的光学矫正中的疗效，并与 Rose-K 2 RGP 隐形眼镜进行比较。
在一项回顾性研究中，对 94 只眼进行了 KIC（A 组）的适配，并与 77 只眼作为对照组的 Rose-K（®）RGP 镜片进行了比较。记录了眼部诊断、角膜地形图曲率、屈光度、最佳矫正视力（BSCVA）和配镜时的年龄。随访数据包括平均每日佩戴时间、隐形眼镜并发症、佩戴隐形眼镜时的视力（BCLCVA）、镜片屈光度和随访时间。
两组间 BCLCVA 或佩戴时间均无统计学差异（p = 0.63，p = 0.15）。RGP 组发现更多的生物显微镜并发症，主要是角膜染色（P < 0.0001）。在 KIC 组，角膜扩张症的类型间 BCLCVA 无统计学差异（p = 0.19），轻中度圆锥角膜之间也无统计学差异（p = 0.45）。
KIC 是治疗非手术性角膜扩张症（如圆锥角膜和边缘性角膜变性）不规则角膜散光的一种良好选择。
