To evaluate the utility of the Rose K2 XL semi-scleral contact lens (Menicon Co. Ltd., Nagoya, Japan) in the management of the irregular cornea.
Twenty-seven subjects (34 eyes) with irregular corneas referred for contact lens fitting were evaluated. A diagnostic trial set was used in the fitting process. Once the trial lens was considered optimal, a final lens was ordered from the manufacturer with the necessary changes in power, edge lift and diameter. We analyzed visual acuity, number of lenses ordered and patients' ability to wear and handle lenses.
Twenty-three subjects (30 eyes) were fitted with the Rose K2 XL lens. Four subjects (4 eyes) decided not to conclude the fitting process for different reasons. Average logMAR visual acuity without correction and with the lens was 0.82 and 0.09, respectively (p<0.001). An average of 1.4 ordered lenses (range 1-3) were necessary to achieve the optimal fit. Nineteen eyes (63%) were fitted with the first lens ordered. Three subjects (13%) had problems with lens handling, and three subjects (4 eyes) abandoned the wear of the lenses after three months due to discomfort (3 eyes) and unsatisfactory visual acuity (1 eye), respectively. Follow-up ranged from 6 to 9 months.
Rose K2 XL semi-scleral contact lens provides good visual acuity and comfort in patients with irregular corneas.
评估 Rose K2 XL 巩膜半接触镜（日本美尼康株式会社）在处理不规则角膜中的应用效果。
对 27 名（34 只眼）需要配接触镜的不规则角膜患者进行评估。在适配过程中使用了诊断试戴镜。一旦认为试戴镜是最佳选择，就从制造商处订购具有必要功率、边缘提升和直径变化的最终镜片。我们分析了视力、订购镜片的数量以及患者戴镜和处理镜片的能力。
23 名患者（30 只眼）适配了 Rose K2 XL 镜片。4 名患者（4 只眼）由于不同原因决定不继续适配过程。不矫正时和戴镜时的平均 logMAR 视力分别为 0.82 和 0.09（p<0.001）。平均需要 1.4 副（1-3 副）镜片才能达到最佳适配。19 只眼（63%）第一副订购的镜片适配成功。3 名患者（13%）在处理镜片方面存在问题，3 名患者（4 只眼）在佩戴三个月后因不适（3 只眼）和不满意的视力（1 只眼）而放弃佩戴，随访时间为 6-9 个月。
Rose K2 XL 巩膜半接触镜可为不规则角膜患者提供良好的视力和舒适度。
