Abstract:AIM: To observe the visual quality and capsular stability after implantation ofAcrysof Toric intraocular lens(IOL)in cataract patients with corneal astigmatism.
METHODS: Totally 20 patients 23 eyes were implanted with the Acrysof Toric IOL between April 2010 and April 2012. All the patients were followed up for 12 months. The pre and post-operative uncorrected visual acuity(UCVA), preoperative corneal astigmatism, postoperative residual astigmatism, IOL axis, IOL decentration, IOL tilt and the capsule were detected and measured.
RESULTS: After 12 months, UCVA was ≥0.6 in 23 eyes(100%); ≥0.8 in 17 eyes(74%). The mean preoperative corneal astigmatism was(2.31±0.70)D and the postoperative refractive cylinder was(0.43±0.28)D, which was statistically significance(P=0.00). The mean rotation of Toric IOL in 17 eyes(74%)was(4.98±0.25)°, of which 2 cases' rotation was >10°, the maximum was 12.9°. IOL decentration was in 11 eyes(48%)in which 7 eyes(30%)<0.5mm, 0.5mm≤3 eyes(13%)≤1mm, 1 eye(4%)=1.1mm. 20 eyes(87%)was not tilted while 3 eyes(13%)was tilted an less than 5°.
CONCLUSION: Implantation of theAcrysof Toric IOL proves to be an effective, safe, and stable method of managing corneal astigmatism in cataract patients and provides patients with good visual quality. The Acrysof Toric IOL demonstrates excellent rotation and centration stability.
