Abstract Details


To analyse the rotational stability of hydrophilic Rayner T-flex IOL over 4 years post-surgery using serial digital photographs and software.


Scarborough Hospital, Scarborough, United Kingdom


In a prospective study over 2 years, 12 eyes with keratometric cylinder of ? 2.5D underwent routine phacoemulsification with in-the bag implantation of hydrophilic Rayner T-flex IOL. This lens has anti-vaulting haptics designed for rotational stability. Slit-lamp digital photographs were taken after maximal pupillary dilatation at 1 week, 6 months and 2 years post-operatively and analysed with Adobe Acrobat Professional software. Unaided acuities were recorded and patients were asked to rate the visual outcome as highly satisfied, satisfied or not satisfied. Patients will be called to collect 4 years results.


Eyes were grouped based on the extent of IOL rotation (? 5 degrees, 5-10 degrees and > 10 degrees). At 2 years, all 12 eyes showed IOL rotation of < 5 degrees post-surgery. Unaided acuity was 20/40 or better in 11 out of 12 eyes. All but one patient were highly satisfied with the outcome of the surgery. 4 years follow up data will be added.


Rayner T-flex Toric IOL showed excellent rotational stability at 2 years post-surgery. It also provided excellent post-operative unaided visual acuity with a high patient satisfaction rate. Conclusions at 4 years follow up will be added.
