Correction of astigmatism with toric IOL

Purpose: To evaluate stability of toric IOL model TSN60T3-T4-T5 (Alcon) after cataract surgery with endocapsular IOL implantation. Methods: 23 eyes were operated. Age of patients was from 35 to 74 years.

Vertical meridian of cornea was marked before surgery and steep axis – during surgery. Diameter of anterior CCC was 4–4,5mm. Cataract was removed using phacoemulsification method and IOL (SA60T5–16, SA60T4–4, SA60T3–3 units) inserted through 2,2mm temporal corneal incision. OVD were removed carefully, especially from behind of the IOL optics. IOL was stuck to the posterior capsule after aligning of marks on the IOL with markers of steep meridian of cornea. No sutures were placed. Results: Position of the toric element of IOL during follow-up time (1 month) was almost stable; rotation of IOL first day after surgery was 1,73±1,21° (max 4°) and 1,79±1,55° (max 4°) after 1 months. Uncorrected/corrected visual acuity 1 day after surgery was 0,88±0,23/0,90±0,22 and 0,85±0,10/0,92±0,06 1 months after surgery respectively. Conclusions: Available toric IOL made from hydrophobic acrylic material after endocapsular implantation is a good option for preoperative astigmatism of moderate degree correction.
