目的：评估高度近视患者有晶状体眼后房型人工晶状体(ICL V4c)植入术后早期双眼视觉功能。

方法：前瞻性研究。观察2019-05/2021-05在我院行双眼ICL植入术的高度近视患者35例70眼。术前和术后1 mo评估双眼全程视力、双眼对比度敏感度、双眼立体视、双眼中间视觉及眩光敏感度、单眼波前像差及视觉质量调查问卷。

结果：术后1 mo双眼裸眼远视力(UDVA)≤0.00(LogMAR)者35例(100%)，双眼UDVA≥术前最佳矫正视力(CDVA)者16例(46%)。术后双眼裸眼远视力(UDVA)、中视力(UIVA， 80 cm)较术前CDVA、最佳矫正远视力下中视力(DCIVA，80 cm)均有所提升(均P<0.05)； 双眼术后UIVA(60 cm)与术前DCIVA(60 cm)、双眼术后裸眼近视力(UNVA，40 cm)较术前最佳矫正远视力下近视力(40 cm)，均无差异(均P>0.05)。术后双眼对比度敏感度较术前好转(P=0.001)。术后双眼中间视觉及眩光敏感度(无眩光)、中间视觉及眩光敏感度(眩光)，较术前均无差异(均P>0.05)。手术前后双眼5 m和40 cm立体视比较均无差异(均P>0.05)。除在瞳孔直径3.0 mm下右眼全眼彗差术后较术前中位数减小，余全眼总高阶像差、三叶草像差、彗差及球面像差术后较术前中位数均有所增加。患者术前及术后的主观视觉质量量表评分总分均值由54.87分显著提升至80.92分(P<0.05)，患者术后满意度高、无明确视觉干扰症状。

结论； 高度近视患者双眼植入ICL V4c术后早期单眼全眼高阶像差虽有所增加，但双眼视觉功能得到改善。

METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.

RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.

CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.
