Abstract Details


In the search for the optimal toric intraocular lens (IOL) that deliver the best visual outcomes and least post operative misalignment, the new transitional conic surface toric IOL are claimed to offer greater tolerance to misalignment with improved visual outcomes.


Tertiary referral centre in the UK


Prospective, non-randomised, single centre. Cataract patients with pre-existing corneal astigmatism of more than 2 diopters were offered toric IOL implantation using the new conic toric IOL. All participants had no pre-existing eye disease except the cataract and attended a minimum of 6 months follow up. Outcomes measures for efficacy were IOL alignment, Change in UDVA, Change in CDVA, Post-op SE, and refractive outcomes in particular change in astigmatism vectors. Safety measures were a reduction in CDVA by more than 2 lines, and intra/post-operative complications.


27 eyes (24 patients) with pre-existing corneal astigmatism mean 2.64 (1.95-5.22). The average age was 74.7 years. Mean pre-op UDVA 0.78±0.14 and CDVA 0.70±0.16 improved at 6 months to mean UDVA 0.04±0.10 and mean CDVA 0.01±0.08. The mean reduction in the refractive cylinder was 77.88%±15.05. Average misalignment was 5 degrees in the total 9 cases where the IOL has rotated; none needed surgical intervention. No patient lost more than 2 lines and no operative or postoperative complications.


Transitional conic IOL is a new concept in toric IOLs. It is a safe and effective new technology. Larger randomised controlled trial will be useful
