Abstract Details

Purpose:

To report post-operative uncorrected distance visual acuity (UDVA), spherical equivalent (SE) using a toric intraocular lens (IOL) Acrysof IQ SN6AT-range (Alcon Laboratories, Inc.), in the context of a post-graduate training centre within the National Health Service (NHS).

Setting:

Cataract Service, Moorfields Eye Hospital, NHS Foundation Trust, London, United Kingdom (UK).

Methods:

Retrospective analysis of 272 eyes that underwent insertion of Acrysof IQ toric IOL following calculation using online Alcon toric IOL calculator, by post-graduate Trainee/Fellow versus Consultant surgeons and by IOL subtype (ie SN6AT3 to SN6AT9).

Results:

Mean post-operative UDVA Trainees/Fellows (n=115) = 6/11 (Snellen) and Consultants (n=156) = 6/27 (Snellen), p=0.79. Mean post-operative SE Trainees/Fellows (n=115) = -0.36D, and Consultants (n=156) = -0.29D,p=0.46. Mean post-operative residual astigmatism (RA) Trainees/Fellows (n=115) -1.19D and Consultants (n=156)=-1.11D, p= 0.44 (unpaired t-test). Mean post-operative UDVA (Snellen) by IOL subtype T3(n=3)= 6/8, T4(n=44)= 6/9, T5(n=60)= 6/11, T6(n=64)= 6/11, T7 (n=37)= 6/11, T8(n=18)= 6/12 and T9 (n=46)= 6/13. Mean SE achieved versus target refraction IOL by subtype T3 (n=3)= 0.312D T4 (n=44)= 0.046D T5(n=60)= 0.024D T6(n=64)= 0.413D T7 (n=37) = -0.320D T8(n=18)= 0.05D T9 (n=46) = -0.03D. 84% of patients achieved uncorrected distance vision of 6/12 Snellen acuity or better i.e. UK visual driving standard.

Conclusions:

There was no significant difference in outcomes between Trainee/Fellow versus Consultant surgeons or between IOL subtype. However, a larger RA approaching 2D was found in the SN6AT9 subtype as it corrects only up to 4.11D at the corneal plane and such patients should be advised accordingly of a higher predicted RA than SN6AT3 to SN6AT8.
