Abstract Details

Purpose:

To study the refractive results after more than 600 implantations of Toric MICS IOL during cataract surgery with hydrophilic acrylic lens.

Setting:

Centre Ophtalmologique IRIDIS, Albi, France.

Methods:

This prospective study comprises all patients who were implanted in 2018-20 by the same surgeon in BMICS with AT TORBI 709M/MP (11mm) (CZM) bitoric IOL hydrophilic acrylic lenses and Ankoris (11.4mm) (BVI-PhysIOL). The goal was to correct total astigmatism with the calculator Z align and optimization with TK data (IOLMaster 700 CZM).IOL choice was done on corneal diameter (CD) measure with Ankoris for CD over 12mm and AT TORBI under 12mm. A control group is done with Ankoris under 12mm. Analysis of VA, Astigmatism, TK pre and postop and rotation by dilation at M3.

Results:

The mean age is 76.25 years (SD ±8.70) with a preoperative anterior corneal astigmatism of 1.17D (SD ±0.82) and mean total corneal astigmatism of 1.25D (SD ±0.74). The mean final post op astigmatism is 0.12D (SD ±0.20) with 66.3% of patients with 0D astigmatism, 88.7% ±0.25D, 92,4% ±0.50D, 99.9% ±0.75D and 100% ±1D. The rotation was respectively for AT TORBI and Ankoris 2° (SD±5.19) and 6° (SD±5.34). For a small sample with both IOLs implanted with CD under 12mm the result is AT TORBI 3.8° and Ankoris 4°. The final analysis of the control group will be done.The SIA for all implantations is 0.32 at 80.53°.

Conclusions:

The main concern for astigmatism correction remains SIA, accuracy in IOL power, axis and postop IOL rotation. Microincision, TK from IOLMaster and IOL design adapted to the corneal diameter can improve the final results. This new concept to limit IOL rotation will be discussed to obtain more accurate results.
