Abstract Details


To ascertain real-world visual and refractive outcomes following toric intraocular (IOL) insertion in patients undergoing cataract surgery at a tertiary referral centre in the UK (UK).


The Western Eye Hospital, Imperial College Healthcare National Health Service (NHS) Trust, London, UK.


This was a retrospective study of all patients who underwent surgery for age-related cataract with toric IOL insertion at the Western Eye Hospital between November 2014 and November 2016. All patients had preoperative keratometric regular astigmatism of ≥2.00 dioptres (D), as per local protocol. A T-flex 623T Rayner toric IOL was used in all cases. Visual acuities are presented in logMAR.


114 eyes (95 patients) were identified, mean age 70 years and 45% male. The mean preoperative best corrected visual acuity was 0.50, improving to a mean uncorrected visual acuity (UCVA) of 0.35 postoperatively (p<0.001) with 65% of patients attaining an UCVA ≥0.30. Excluding 32 patients with pre-existing visual co-morbidities and one aiming for monovision, mean postoperative UCVA was 0.24 (p<0.001) and 85% had UCVA ≥0.30. The mean refractive astigmatism improved from 3.04D to 1.36D (p<0.001). Toric IOL misalignment was noted postoperatively in 2 patients and 2 cases of posterior capsule rupture required conversion to an aspheric IOL.


Toric IOL insertion is a safe and effective method of astigmatic correction at the time of cataract surgery. Our results may be used as a reference for other centres to audit their own outcomes against. More real-world studies including higher degrees of preoperative astigmatism are needed.
