To evaluate the clinical outcomes of laser in situ keratomileusis (LASIK) using a new approach for the calculation of the ablation profile based on wavefront vertexing from pupil plane to corneal.
One hundred eyes of 50 patients (age, 21-41 years) with low and moderate myopia were enrolled in this prospective case series. All of them underwent topography-integrated wavefront-guided (TI-WFG) LASIK using the STAR S4IR excimer laser platform (Johnson & Johnson Vision). Visual, refractive, ocular aberrometric, ocular scattering index (OSI) and patient satisfaction outcomes were evaluated after a 90-day follow-up period. Astigmatic changes were evaluated by vector analysis.
A significant reduction in sphere and cylinder ( < .001) was observed, with a significant improvement in uncorrected (UDVA) and corrected distance visual acuity (CDVA) ( < .001). Postoperative spherical equivalent was within ±0.50 and ±1.00 D in 91.1% (82/90) and 98.9% (89/90) of eyes, respectively. UDVA was 20/20 or better in 98.9% (89/90) of eyes. A total of 50.0% (45/90) of eyes gained 1 line of CDVA. Mean postoperative astigmatic correction index and angle of error were 1.01 ± 0.56 and 0.17 ± 0.18º. Postoperative high-order aberrometric coefficients were below 0.50 μm in 92.2% (83/90) of eyes. Mean postoperative OSI was 0.71 ± 0.44. All patients referred to be satisfied with the final outcomes and would recommend the procedure to their friends and relatives.
TI-WFG LASIK is a new approach for myopia and myopic astigmatism correction, with preservation of the ocular optical quality and high level of patient satisfaction associated.
评估基于瞳孔平面到角膜顶点的波前顶点进行消融轮廓计算的新方法在准分子激光原位角膜磨镶术(LASIK)中的临床效果。
本前瞻性病例系列研究纳入了 50 例(年龄 21-41 岁)低中度近视患者的 100 只眼。所有患者均在 STAR S4IR 准分子激光平台(Johnson & Johnson Vision)下行基于像差引导的角膜地形图整合 LASIK 手术。术后 90 天随访时,评估视力、屈光、眼像差、眼散射指数(OSI)和患者满意度。通过矢量分析评估散光变化。
术后球镜和柱镜显著降低(均<0.001),未矫正视力(UDVA)和矫正视力(CDVA)显著提高(均<0.001)。术后等效球镜在±0.50 和±1.00 D 范围内的眼分别占 91.1%(82/90)和 98.9%(89/90)。98.9%(89/90)的眼术后 UDVA 达到 20/20 或更好。共有 50.0%(45/90)的眼获得 1 行 CDVA。平均术后散光矫正指数和误差角分别为 1.01±0.56 和 0.17±0.18°。92.2%(83/90)的眼术后高阶像差系数低于 0.50 μm。平均术后 OSI 为 0.71±0.44。所有患者均对最终结果表示满意,并愿意将该手术推荐给他们的朋友和亲戚。
基于像差引导的角膜地形图整合 LASIK 是一种矫正近视和近视散光的新方法,可保留眼部光学质量,患者满意度高。
