Abstract Details

Purpose:

To evaluate trifocal toric IOL to manage astigmatism and near vision after cataract surgery

Setting:

C.M.A. Centro Microchirurgia Ambulatoriale Monza , Italy

Methods:

Eyes with cataract and corneal astigmatism (1.47 ± 0.56 D) had AT LISA tri toric 939MP implantation. IOL calculations were performed using Z-CALC online calculator, taking into account the surgeon SIA. IOL axis alignment during surgery was accurately performed. Outcomes measurements were subjective refraction, corneal astigmatism using ATLAS™ 9000 Corneal Topography System or Tomey TMS 2 Corneal Tomographer, visual acuity, contrast sensitivity using OPTEC 6500

Results:

Study included 50 eyes from 32 patients (mean age 66.36 years ± 13.51). Preoperatively, mean BCVA and SE were 20/28 ± 8.60 and -0.95 D ± 3.23 respectively. Patients presented with a mean corneal cylinder and mean refractive cylinder of 1.47 D ± 0.56 and 0.94 D ± 0.83 respectively. 2 year postoperatively, mean monocular UCVA and BCVA were 0.87 ± 0.17 and 0.93 ± 0.14 respectively for far vision. Intermediate monocular UCVA was 0.45± 0.29. Near monocular UCVA was 0.80. The mean residual refractive cylinder was 0.33 ± 0.33. Photopic contrast sensitivity were within the normal range for lower spatial frequencies.

Conclusions:

AT LISA tri toric 939MP is an advanced generation multifocal IOL preferably indicated for bilateral implantation. Clinical outcomes indicate that this is an effective multifocal design to correct corneal astigmatism and to achieve emmetropia and near vision.
