Purpose: The aim of this study was to compare the refractive results and perioperative complications of a range of current unifocal intraocular lenses. Method: A prospective cohort study involving 550 cases compared the refractive and visual outcomes of patients receiving Alcon WF/Toric, Zeiss Asphina/Torbi, Hoya 251/351, Tecnis one piece/toric or B&L enVista MX60/MX60T. Surgeries were performed by a single surgeon consecutively. Exclusion criteriawerepostoperative BCVA less than 6/9 where intercurrent opthalmic disease could explain the reduced vision. Patients were reviewed at 1day, 1week and 1month postoperatively. Complications were reviewed and discussed. Results: No statistical significant difference was found in UCVA. Statistical difference was noted between the Hoya 351 and the enVista MX60Tx. The Zeiss lenses gave excellent visual outcomes but had the highest complication rates. The enVista MX60 and Alcon SN6ATx gave the best mix of visual outcome and safety, whilst the HOYA lenses offered the most reliable delivery system. The Tecnis lenses were discontinued due to high predictive error, and the enVista MX60T was discontinued due to poor rotational stability. Conclusion: No definitive answer can be made regarding lens choice. However, this study has led us to use the HOYA lens where lens loading is an issue. Where this is not an issue, we use the enVista MX60 where a non toric lens is required and either the Alcon SN6ATx or Zeiss Torbi where a toric lens is required.
