We report a case of a 40-year-old female with keratoconus and high myopia who had previous ICRS implantation in both eyes (OU) and was intolerant to contact lenses. Manifest refraction was -8.50 -1.50 × 95 (20/25--) in right eye (OD) and -9.50 -2.50 × 60 (20/70--) in left eye (OS). A topography-guided transepithelial-photorefractive keratectomy (ttPRK) was performed to correct high-order aberrations on OS, resulting in corneal surface and coma improvement, and CDVA achieved 20/30. Correction of residual ametropia was performed with an iris-fixated toric phakic lens in OU. CDVA improved to 20/20- (Plano) in OD and 20/20- (Plano -1.00 90°) in OS. In conclusion, it is possible to rehabilitate a patient with keratoconus and high ametropia after intrastromal corneal ring segments (ICRS) implantation associating ttPRK and phakic lens ("Trioptics").
我们报告了一例 40 岁女性患者，患有圆锥角膜和高度近视，双眼均植入了 ICRS（Intrastromal Corneal Ring Segments，角膜基质环），并且对隐形眼镜不耐受。右眼（OD）的矫正视力为-8.50 -1.50 × 95（20/25--），左眼（OS）的矫正视力为-9.50 -2.50 × 60（20/70--）。对 OS 进行了基于角膜地形图引导的经上皮准分子光角膜切削术（ttPRK），以矫正高阶像差，从而改善了角膜表面和彗差，并达到了 20/30 的裸眼视力（CDVA）。在双眼植入虹膜固定型有晶状体眼人工晶状体（toric phakic lens）来矫正残余的屈光不正。OD 的 CDVA 提高至 20/20-（平光），OS 的 CDVA 提高至 20/20-（平光-1.00 90°）。总之，在对植入了 ICRS 的圆锥角膜和高度屈光不正患者进行 ttPRK 和有晶状体眼人工晶状体手术（“Trioptics”）后，有可能进行康复治疗。
