Two-year results of AcrySof toric intraocular lens implantation in patients with combined microincision vitrectomy surgery and phacoemulsification

Aim: To evaluate the effects and stability of AcrySof toric intraocular lens (IOL) implantation in patients who had combined microincision vitrectomy surgery (MIVS) and phacoemulsification for vitreoretinal diseases and cataract with corneal astigmatism. Methods: A retrospective comparative study with 20 patients (20 eyes) who had combined 23-gauge MIVS and phacoemulsification with regular corneal astigmatism (>1.00 dioptres) was done. 10 eyes had toric IOL and 10 eyes had non-toric IOL implantation. The main outcome measures were uncorrected visual acuity (UCVA), refractive cylinder and toric IOL axis rotation at postoperative months 1, 6, 12, 18 and 24. Results: The mean UCVA of toric IOL was better than non-toric IOL at each postoperative period (p=0.019, 0.001, 0.007, 0.004 and 0.001, respectively). The mean absolute residual refractive cylinder of toric IOL was less than non-toric IOL at each postoperative period (p=0.001, <0.001, <0.001, <0.001 and <0.001, respectively). At month 24, the mean toric IOL axis rotation was 3.3±2.1°, which was within 5° in 80% and within 10° in 100%. Conclusions: Toric IOL implantation could be an effective method of correcting corneal astigmatism in patients who have vitreoretinal diseases and cataract. The toric IOL showed good rotational stability, even in vitrectomised eyes for 24 months.
