Abstract

Purpose: To report the use of miniscleral contact lenses (MSCLs) with diameter of 14.7 mm for Asian eyes to improve vision in patients after penetrating keratoplasty (PKP) surgery.

Methods: Two patients with high corneal astigmatism post-PKP were evaluated for a contact lens fitting. Visual acuity, slit lamp, and anterior segment OCT findings before and after fitted the lens of 14.7 mm diameter were recorded.

Results: A Kmax of case 1 and 2 were 52.8 D and 76.9 D, respectively at the first visit. Both patients were successfully fit with MSCLs, showing adequate corneal clearance of over 250 μm with no corneal touch on OCT and sufficient limbal clearance and edge alignment. MSCLs use resulted in improved comfort and visual acuity of 20/30 or better.

Conclusion: MSCLs with diameter of 14.7 mm can be considered a safe and effective option for patients with highly steep corneas post-PKP surgery in Asian eyes.

亚洲眼穿透性角膜移植术后小睑孔微型巩膜隐形眼镜一例报告。

目的:报道亚洲眼使用直径为14.7 mm的微晶状体隐形眼镜(MSCLs)改善穿透性角膜移植术(PKP)术后患者的视力。方法:对2例pkp术后角膜高度散光患者进行隐形眼镜配戴评价。记录安装直径14.7 mm晶状体前后的视力、裂隙灯及前段OCT表现。结果:病例1和病例2首次就诊时Kmax分别为52.8 D和76.9 D。两名患者均成功植入mscs，角膜间隙超过250 μm, OCT无角膜接触，角膜缘间隙和边缘对齐。mscl的使用改善了舒适度，视力达到20/30或更好。结论:对于亚洲眼pkp术后角膜高度陡的患者，直径14.7 mm的mscs是一种安全有效的选择。

期刊介绍： Clinical Optometry is an international, peer-reviewed, open access journal focusing on clinical optometry. All aspects of patient care are addressed within the journal as well as the practice of optometry including economic and business analyses. Basic and clinical research papers are published that cover all aspects of optics, refraction and its application to the theory and practice of optometry. Specific topics covered in the journal include: Theoretical and applied optics, Delivery of patient care in optometry practice, Refraction and correction of errors, Screening and preventative aspects of eye disease, Extended clinical roles for optometrists including shared care and provision of medications, Teaching and training optometrists, International aspects of optometry, Business practice, Patient adherence, quality of life, satisfaction, Health economic evaluations.
