Abstract Details

Purpose:

To compare the final astigmatic error using four different types of toric IOLs

Setting:

Department of Ophthalmology, Aarhus University Hospital

Methods:

One hundred and seventy three eyes from one hundred and nine patients with a median preoperatively regular corneal astigmatism of 2.4 D (range from 0.68 to 9.4 ) where operated with one of the following toric IOLs (AMO ZCT, ALCON SN6AT, ZEISS AT TORBI, or HOYA iSert351T). Preoperative corneal astigmatism was calculated and a toric IOL was chosen with the aim to reduce the postoperative astigmatic error below 0.75 D. All patients were examined after the implantation and the postoperative astigmatic error was measured. The preoperative and postoperative astigmatic error was compared using Kruskal-Wallis test.

Results:

81 patients were implanted with AMO ZCT IOLs, 67 patients with ALCON SN6AT IOLs, 14 with ZEISS AT TORBI IOLs and 11 with HOYA iSert351T IOLs The preoperative median astigmatism error were 2.5 D, 3 D, 5.25 D, 3 D for the patients receiving a AMO ZCT, ALCON SN6AT, ZEISS AT TORBI, HOYA iSert351T, respectively). The final median astigmatism error were 0.75 D, 0.75 D, 0.5 D, 0.875 D for the patients receiving a AMO ZCT, ALCON SN6AT, ZEISS AT TORBI, HOYA iSert351T, respectively). No significant difference was found in the difference between postoperative astigmatic errors among the four types of toric IOLs (P=0.65).

Conclusions:

The four types of toric IOLs were good to reduced the final astigmatic error, but no significance was found among the four different toric IOLs FINANCIAL INTEREST: NONE
