  • *Versus preoperative, p<0.05.

  • †3-month follow-up versus the last follow-up, p<0.05.

  • ‡The preoperative refractive power of this eye was −18.75 DS/−3.50 DC×15°. The spherical power was completely corrected and the attempted SE was −2.50 D (−0.75 DS/−3.50 DC×15°).

  • ACA, anterior chamber angle; ACD, anterior chamber depth; ACV, anterior chamber volume; CDVA, corrected distance visual acuity; ECD, endothelium cell density; IOP, intraocular pressure; SE, epherical equivalent; UDVA, uncorrected distance visual acuity.
