영문 초록

Purpose: To evaluate the short-term efficacy of astigmatism correction and rotational stability of AcrySof Toric Intraocular lens (IOL) implants. Method: We analyzed 27 eyes of 23 patients who underwent microcoaxial cataract surgery (MCCS) and AcrySof Toric IOL implantation between March 2008 and July 2008. We evaluated visual acuity, keratometry, and refraction. Slit-lamp retroillumination photographs were obtained in all patients on 1 day, 1 month and 3 months postoperatively. The change of postoperative IOL axis alignment and the presence of anterior capsular shrinkage were analyzed. Result: The mean unaided visual acuity (LogMAR) improved from 1.02±0.38 to 0.10±0.12. Although postoperative manual keratometric value was not different from the preoperative value, post-operative astigmatism decreased from a mean value of 1.66±0.42D to 0.61±0.38D at 3 months postoperatively. The mean difference between achieved and intended lens axis was 1.63±2.83 degrees at the first post-operative day, and 1.91±2.92 degrees on the first postoperative month, with all cases within 10 degrees. There were two cases of IOL rotation between one day and one month postoperative follow-up, and severe anterior capsule contractions were found in them. Conclusions: AcrySof Toric IOL is effective for correction of astigmatism and it has good post-operative rotational stability. Because most of misalignments were found at the postoperative day 1, the precise implantation of IOL, according to the intended axis, can be important during operation and immediately after the operation.
