Purpose . To investigate two-year outcomes of Visian Implantable Collamer Lens with a central hole (ICL V4c) implantation for correcting high myopia. Methods Sixty-one eyes 32 patients went through ICL V4c implantation. Safety, efficacy, predictability, and intraocular pressure were evaluated 2 years postoperatively. Anterior chamber volume (ACV), anterior depth (ACD), angle width (ACAW), vault measured using Scheimpflug tomography imaging system. Results At years, the spherical equivalent refraction decreased from preoperative −14.62 ± 4.29 D to −0.90 0.95 D, 79% within ±0.50 98% ±1.00 intended correction. The efficacy index was 1.03 0.23, safety 1.24 0.26. Corrected distance visual acuity (CDVA) remained unchanged in 23% eyes, 75% gained one or more lines CDVA, 2% lost line. ACV, ACD, ACAW, respectively, 193.28 29.15 mm 3 , 3.15 0.23 mm, 36.51 6.54 degree 112.48 17.01 2.99 22.54 5.27 (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>p</mml:mi><mml:mo>=</mml:mo><mml:mn>0.0008</mml:mn><mml:mo>,</mml:mo><mml:mtext> </mml:mtext><mml:mn>0.008</mml:mn><mml:mo>,</mml:mo><mml:mtext> </mml:mtext><mml:mn>0.0003</mml:mn></mml:mrow></mml:math>, resp.).
