Abstract Details

Purpose:

To evaluate trifocal toric IOL to manage astigmatism to get postop emmetropia and best near vision after cataract surgery. To demonstrate that Trifocal technology IOLs has replaced Bifocal IOLs in Countries were available

Setting:

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

Methods:

Eyes with cataract and corneal astigmatism (1.45 ± 0.53 D) had AT LISA tri toric 939MP implantation. Toric correction was adopted when an astigmatism of 0.75 diopters or more was detected by corneal map evaluation.IOL calculations were performed using Z-CALC online calculator, taking into account the surgeon SIA. IOL axis alignment during surgery was accurately performed also using Callisto device. 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 123 eyes from 76 patients (mean age 66.93 years ± 12.04). Preoperatively, mean BCVA and SE were 20/30 ± 13.80 and -1.16 D ± 3.78 respectively. Patients presented with a mean corneal cylinder and mean refractive cylinder of 1.45 D ± 0.53 and 0.95 D ± 0.84 respectively. 4 years postoperatively, mean monocular UCVA and BCVA were 20/23 ± 0.17 and 20/21 ± 3.61 respectively for far vision. Intermediate monocular UCVA was 20/25 ± 0.29. Near monocular UCVA was 20/27. The mean residual refractive cylinder was 0.40 ± 0.31. Photopic contrast sensitivity were within the normal range.

Conclusions:

AT LISA tri toric 939MP is an advanced generation of multifocal IOL indicated for bilateral implantation. Clinical outcomes indicate that this is the more effective multifocal design to correct corneal astigmatism and to achieve emmetropia and near vision. It is mandatory to adopt toric correction when an astigmatism of 0.75 diopters or more was detected by corneal map evaluation. Using the proper advanced technology and organization we have got in 83% of the eyes a refractive results within +- 0,50 diopters. Almost in one eyes in 94% of patients
