Purpose:To investigate a customised aspheric,toric,multifocal IOL(Rayner M-Flex T)implanted in patients presenting for presbyopic refractive lens exchange.
Method:Four patients aged between 47-58 years received 6 aspheric,toric,multifocal IOLs(custom made by Rayner Inc.UK).The preoperative sphere ranged from-8.0 to+9.0 D with corneal astigmatism between-2.5 to-4.75 D.Two patients received Mix&Match implantation of the Tecnis ZM900(AMO)multifocal IOL in the fellow eye.
Results:ix months postoperatively,the uncorrected distance visual acuity was 20/30,the uncorrected near visual acuity was 20/40.The median difference target vs.achieved refraction was 0.13 D(spherical equivalent)and-0.4 D(cylinder).Furthermore,high patient satisfaction was achieved in the Mix&Match group.
Conclusion:According to these results the addition of a fixed torus to a multifocal IOL is possible and will increase the numbers of selectable patients for multifocal IOL implantation.The M-Flex T provides reliable postoperative results not only for bilateral but also for Mix&Match implantation.
