Abstract Details

Purpose:

to identify the amount of residual refractive astigmatism in patients who underwent cataract surgery and toric IOL implantation (Zeiss AT TORBI 709 M/MP) in OKC Pfeifer, Ljubljana Slovenia.

Setting:

In the study were included 194 eyes of 134 patients who underwent cataract surgery and toric IOL implantation at OKC Pfeifer from January 2016 to September 2018.

Methods:

Statistical analysis was performed to determine uncorrected and best corrected visual acuity (UCDVA / BCDVA) using Snellen charts and the amount of residual astigmatism. Follow up was 2 to 20 months after the surgery. The mean sphere power of the implanted toric IOL was +16,7DSph and the median was +18.50DSph (range: 1.00DSph to +26.50DSph). The mean cylinder of the IOL was 2.43DCyl, the median was 2.00DCyl (range: 1.00DCyl to 10.00DCyl).

Results:

Mean BCDVA before surgery was 0.50 (range: CF to 1.00). Mean preoperative refraction was -1,60 D Sph, (range: -20.00DSph to +6.50DSph). Mean preoperative refractive cylinder was 1,5Cyl (range: 0DCyl to 6.0DCyl). Mean keratometry was 44.471D (range: 41.06D to 50.32D). Mean corneal astigmatism was 1.88DCyl  (range: 0,5DCyl to 7.25DCyl). Postoperative mean UCDVA was 0.86 (range: 0.16 to 1.20) and the mean BCDVA was 1.00 (range 0.30 to 1.50). Mean postoperative refraction was +0.15DSph (range: -0.75DSph to +1.75DSph). The mean postoperative refractive astigmatism was  0.31DCyl (range: 0D to 1,75DCyl). Mean spherical equivalent was 0.003 (range: -0.75 to 1,5).

Conclusions:

The residual postoperative astigmatism was very low in patients with corneal astigmatism who underwent cataract surgery and toric IOL (Zeiss AT TORBI 709 M/MP) implantation. Patients uncorrected visual acuity improved significantly and consequently also the quality of life.
