A foldable phakic posterior chamber Collamer toric lens was injected through a standard 3.0-mm clear corneal temporal incision. Uncorrected distance visual acuity (UCDVA, logMAR), best-corrected distance visual acuity (BCDVA, logMAR), spherical refraction, cylindrical refraction, and refractive spherical equivalent (RSE) were measured preoperatively and postoperatively.

The BCDVA changes were not significant (0.09\u00b10.11 vs 0.05\u00b10.08). All patients gained \u22655 lines of UCDVA (average 7.6\u00b11.9 lines). The number of patients with UCDVA \u22656\/12 (0.3 logMAR) increased after surgery (0% vs 87.5%; p&lt;0.01), while the number of patients with BCDVA \u22656\/12 was unchanged (100% vs 100%; NS), with 0% (0\/7) of patients losing \u22652 BCDVA lines.
