Abstract:AIM: To observe the clinical outcome of implanting AcrySof IQ Toric intraocular lens to correct corneal astigmatism in cataract surgery, and to evaluate the result and rotational stability of AcrySof IQ Toric after cataract surgery.
METHODS: A retrospective study of 26 eyes in 21 cataract patients with corneal astigmatism. All patients implanted AcrySof IQ Toric intraocular lens. The preoperative and postoperative uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), preoperative corneal astigmatism, anticipated residual astigmatism, total astigmatism, postoperative residual astigmatism and Toric lens axis were detected and measured.
RESULTS: All patients' visual acuity and best corrected visual acuity improved significantly. The mean refractive cylinder decreased significantly after surgery from(2.05±0.57)D to(0.55±0.33)D(t=13.574, P<0.05). There was no significant difference between preoperative(0.47±0.19)D and postoperative corneal astigmatism(t=1.149, P>0.05). Three months after surgery, there was no significant difference between preoperative(2.01±0.58)D and postoperative(-1.89±0.53)D corneal astigmatism(t=1.908, P>0.05). The rotation of intraocular lens were <20°, the mean rotation was 3.65°±2.86°.
CONCLUSION: The AcrySof IQ Toric lens make cataract patients enjoy the better UCVA including good rotational stability in the correct of corneal astigmatism. The AcrySof IQ Toric implantation is an effective option for the correct of preexisting corneal astigmatism in cataract surgery.
