Purpose
To report the refractive outcomes of patients following implantation of low toric trifocal IOLs (AT-Lisa 939; Carl Zeiss Meditec) in terms of postoperative refraction and uncorrected distance visual acuity.
Setting
Single-center study.
Methods
Retrospective case series. Adult patients that underwent refractive lens exchange surgery or cataract surgery with primary phacoemulsiphication and posterior chamber AT-Lisa trifocal toric 939MP IOL low cylinder (1.0D and 1.5D versions) implantation were evaluated preoperatively and 3 months postoperatively for uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent (SE), and refractive astigmatism.
Results
Overall, 100 eyes of 100 patients were included in the study. 78% of eyes achieved logMAR 0 or better postoperative UDVA, versus 94% in preoperative UDVA. 93% of eyes had a postoperative refractive astigmatism within 0.5D, mean preoperative refractive astigmatism was 0.59 ± 0.48D and improved significantly to 0.25 ± 0.29D.
Conclusions
Correcting mild degrees of astigmatism can improve postoperative UCDVA and reduce spectacle dependence. A low toric power IOL improved postoperative uncorrected visual acuity and reduced refractive astigmatism. Using toric IOLs is recommended if predicted refraction shows improvement.
