Abstract Details

Purpose:

The purpose of the study was to assess the results of the cataract surgery with simultaneous astigmatism correction with the toric intraocular lens, and answer if rotation stability and changes in contrast sensitivity have influence on patients’ subjective satisfaction.

Setting:

University Centre of Ophthalmology and Oncology Silesian University of Medicine, Katowice, Poland

Methods:

The research was based on 40 eyes of 28 patients (22 females and 6 males) at the average age of 59,85years with corneal astigmatism higher than 1.25D received the T-flex toric IOL (Rayner). Outcomes included stability, efficacy, safety, predictability, contrast sensitivity, rotation, patient satisfaction. Follow-up was until 24-48 months. Toric IOL rotation angle was drawn after 6, 12, 24 and 48 months after surgery and the patient filled in an additional control satisfaction questionnaire. Preoperative complete refractive astigmatism 2,74 ± 1,08 D, corneal astigmatism 2,52 ± 0,75 D, lenticular astigmatism 0,22 ± 0,79 D.

Results:

Post-op UDVA was 25 times better than pre-op CDVA. For CDVA, 94% and 5% of eyes gained 1 and 9 lines, respectively. Refractive predictability increased from 85% (day 1) to 95% (1 month). Only 1% of all eyes lost 1 line of CDVA. CDVA have not changed in 5.5% of all eyes, whereas the 93.5% gained 1 line. Average rotation after 6 months was 2˚. Rotation was <10˚ in 97.5% of eyes. Contrast sensitivity improved significantly. Spectacle usage reduced by 48.1% and patients reported reduced difficulty (36.2%) performing sight-dependent activities.

Conclusions:

The T-Flex toric IOL improves visual quality and distance spectacle independence. The level of patients subjective satisfaction and rotational stability are very high.
